Instalasi Database Oracle di Windows XP

Oracle merupakan salah satu software yang sering digunakan sebagai salah satu software database. artikel ini bertujuan untuk sharing-sharing pengalaman kepada teman-teman yang sedang belajar tentang database oracle. artikel ini juga merupakan saduran dari beberapa artikel yang di susun menjadi satu sehingga menjadi suatu artikel yang cukup bermanfaat bagi teman-teman yang ingin belajar database oracle dari awal.

Download software Database Oracle dulu. Free, alias gratis… tis.. Sebelumnya anda harus punya account di Oracle. Kalau belum punya, membuatnya gampang sekali, yang penting punya email. Ikuti saja proses “sign up”. Kalau diminta memasukkan pin OPN, dan anda tidak punya pin OPN karena company anda bukan partner-nya Oracle, kosongkan saja.

Berikut ini panduan download “Oracle Database 10g Release 2 (10.2.0.1.0)”:

1. Buka link (page) untuk download di sini
http://www.oracle.com/technology/software/products/database/index.html
2. Pilih versi database dan tipe OS

Dalam hal ini saya memilih “Oracle Database 10g Release 2 (10.2.0.1.0) for Microsoft Windows”
3. Kemudian muncul pilihan berikut
- Oracle Database 10g Release 2 (10.2.0.1.0)
- Oracle Database 10g Companion CD Release 2 (10.2.0.1.0)
- Oracle Database 10g Client Release 2 (10.2.0.1.0)
- Oracle Clusterware Release 2 (10.2.0.1.0)
- Oracle Gateways 10g Release 2 (10.2.0.1.0) (10.2.0.1.0)

Pilihlah option pertama. Kalau hanya untuk sekedar belajar database, anda cukup milih option pertama saja.

PC yang saya gunakan dalam instalasi ini adalah:
- Microsoft Windows XP Professional Version 2002 Service Pack 2
- CPU: intel 2 Ghz
- Memory: 1G
- Virtual (page) memory: 1,5G

Dengan spesifikasi tersebut, jelas PC saya sangat (lebih dari cukup) memenuhi syarat. Lebih detail tentang spesifikasi komputer yang bisa diinstall, lihat dokumentasi (installation guide) yang ada di paket software yang telah di download. Secara umum, berikut ini spesifikasinya:
Hardware:
- Physical memory (RAM) : 256 MB minimum, 512 MB recommended
- Virtual memory: dua kali RAM
- Disk space: kira-kira 5 G
- Video (monitor) adapter: 256 colors
- Processor : 550 MHz

Operating system (OS)
- Windows 2000 with service pack 1 or later. All editions, including Terminal Services and Microsoft Windows 2000 MultiLanguage Edition (MLE)
- Windows Server 2003 - all editions
- Windows XP Professional
- Windows NT is not supported.
Berikut ini langkah-langkahnya:

1. Jalankan command “setup.exe” yang ada di paket software yang telah di download
Kemudian muncul Install wizard (GUI).
- Pilih option “Basic Installation”
- Masukkan directory “Oracle Home Location”
- Pilih “Installation Type”
- Jangan pilih “Create Starter Database”
- Klik button “Next”
2. Oracle installer akan mengecek OS kita, apakah requirement-nya dipenuhi atau tidak. Setelah itu Pastikan semua statusnya “Succeeded”. Kalau ada warning, atau statusnya bukan Succeed, bereskan dulu OS-nya. Kemudian klik button “Next”
3. Dalam proses installati, Oracle akan menjalankan program java. Bila firewall PC anda memblock java, dan muncul alert “Windows Security Alert”, kilk tombol “Unblock”.
4. Muncul summary komponen Oracle Database 10g yang siap kita install. Kemudian klik tombol “Install”
5. Setelah itu akan terjadi proses Instalasi
6. Setelah itu akan dilakukan konfigurasi tambahan oleh Oracle Installer. Kita cukup perhatikan saja. Setelah konfigurasi selesai, klik tombol “Next”. Kadang-kadang kita tidak perlu kilk tombol Next tersebut, secara otomatis wizard menuju ke berikutnya.
7. Akhirnya instalasi selesai. Setelah itu klik tombol “Exit”

Dilema WP dan Blogspot.

Belakangan ini ane dilema mau nentuin apakah tetep ingin berdiam diri di blogger atau hijrah ke tetangganya yaitu WP (wordpress). sebenarnya seh baik itu WP ataupun BG sama-sama bagus, baik itu dari system, kelengkapan widget, theme hingga security, tapi menurut ane WP lebih berada sedikit di depat karena sudah mendukung CMS dan Open Source yang dimana dengan adanya fitur ini para blogger dapat lebih leluasa berimajinasi untuk mengembangkan Blognya..

Setelah browsing membandingkan beberapa blog-blog yang gunain WP ama BG ane dapat beberapa blog yang membahas tentang kelebihan masing2 dari 2 produk itu (untuk link back nya ngak ane ikut kasi karena ini artikel udah beredar di mana-mana,, jadi dah g jelas siapa yang punya nya).

ok deh gan, langsung aja deh,, agan-agan compare 2 binatang ini and milih mana menurut agan yang manteps..

Keunggulan Worpress

1. Install di localhost.
WordPress bukan sekadar menyediakan situs blog gratis seperti blogger.com namun WordPress juga menyediakan CMS yang dapat anda instal pada localhost di komputer anda. Namun karena asumsi saya adalah anda ingin segera berbisnis di internet, maka masalah localhost ini tidak akan saya bahas di sini.

2. Install online.
Jika anda mengikuti petunjuk yang saya jelaskan pada materi Hosting, Domain dan Control Panel maka wordpress dapat anda install dengan lebih mudah dan praktis secara online. Hanya beberapa kaliklik jadilah blog anda.

3. Kemampuan UTC.
WordPress memungkinkan anda mengatur waktu berdasarkan Universal Coordinated Time (UTC). Hal ini akan membantu anda mengatur waktu sesuai lokasi anda di mana pun anda berada, sekalipun host server anda berbeda waktu.

4. Kompresi Gzip.
Mengompres file dengan Gzip akan membantu anda mengurangi biaya bandwidth situs anda dan WordPress. Memungkinkan untuk melakukan hal tersebut.

5. Multi user. WordPress memungkinkan anda membuat situs komunitas sendiri seperti halnya sebuah web forum dengan mengaktifkan sesi multi user maka setiap pengunjung yang mendatangi situs anda dapat berperan aktif sebagai kontributor.

6. User ability.
Semua user dapat diatur hak aksesnya dan profilnya sesuai keinginan admin sendiri termasuk profil pengguna yang ingin ditampilkan pada blog.

Plugin sangat esensial untuk menambah berbagai fungsi blog anda. Ada ribuan plugin yang dapat gunakan beberapa di antara akan membantu anda memperoleh uang dari blog yang anda buat. Hebatnya adalah sejak versi Wordpres 2.7 xx plugin sudah bisa diinstall online tanpa harus masuk kontrol panel hosting.

18. Desain template.
Dalam wordpress anda mudah mengedit tampilan blog anda langsung melalui internet browser tanpa harus mengunduh atau unggah file.

19. Tag template.
Setiap template/tema yang ada pada WordPress sudah terdapat tag yang memudahkan anda dalam mengeditnya.

20. Proteksi password.
Anda ingin artikel anda hanya terlihat bagi sebagian orang, ya anda dapat menggunakan kata sandi pada artikel yang anda buat agar hanya dapat diakses bagi yang pemilik kata sandi tersebut.

21. Post slug.
Post slug ialah menghubungkan artikel satu dengan artikel yang lainnya di dalam blog anda. Jadi pembaca dapat membaca artikel berseri milik anda dengan mudah.

22. Waktu posting.
Dalam WordPress anda dapat menyimpan tulisan yang telah anda buat dan memublikasikannya nanti.

23. Simpan tulisan.
Anda juga dapat dengan mudah menyimpan tulisan secara permanen atau sementara untuk anda edit kembali nanti sebelum dipublikasikan.

24. Membagi tulisan.
Jika anda menulis terlalu panjang anda dapat membagi tulisan tersebut ke dalam beberapa halaman.

25. Unggah gambar dan file.

Keunggulan Blogger

1. user friendly
blogspot memiliki fitur yang paling mudah di gunakan terutama untuk pemula.

2. seo friendly
walaupun hampir semua orang mengatakan wordpress lebih seo friendly. Namun blogger juga sudah seo friendly tanpa kita membuat perubahan pun.Jadi masih sangat sesuai buat blogger pemula yang belum mengerti bahasa pemrograman

3. aman dan jarang eror
kalau dipikir pikir kayaknya memakai blogspot akan aman-aman saja,karena blogspot di miliki oleh google. Sebagai portal terbesar dunia kayaknya google bakal selalu memberi kualitas yang terbaik kepada pengguna, jadi tak perlu kawatir.

4. kemudahan posting
blogger menyediakan fasilitas posting yang mudah baik secara langsung,lewat e mail ataupun yang terbaru lewat sms

5. Bisa megunakan javascrib
Yang ini nih penting bagi kita-kita yang pengin nyari uang tambahan didunia maya alias internet.

6. Kode HTML/source code-nya Terbuka
Dengan demikian kita lebih leluasa untuk memodifikasi tampilan blog sesuka hati.

7. Pilihan Template bermacam-macam
Koleksi template ada banyak pilihan, dimana kita bisa langsung pakai dan bisa pula memodifikasinya sendiri tanpa harus mempelajari HTML, Blogger/ blogspot juga mengizinkan pengeditan kode HTML blog kapanpun.

8. Warna dan font kustom yang bervariasi
Kita bisa dengan leluasa mengkustomisasi template yang telah kita ambil secara Cuma-Cuma di koleksinya blogger, kita bisa menganti warna dan huruf sesuai dengan keinginan kita.

9. Seret dan jatuhkan elemen laman
Dengan Sistem sederhana seret dan jatuhkan ini mempermudah kita untuk meletakan komponen halaman seperti posting, profil, arsip dan bagian lainnya sesuai keinginan dan kebutuhan kita.

10. Bisa ditukar ke domain sendiri
Kita bisa menukar dari domainmu.Blogspot.com ke domainmu.Com kapan saja, cukup dengan beberapa setting ringan. Jika kita mengubah alamat domain tak perlu kawatir akan kehilangan pelanggan atau pengunjung situs karena visitor yang mengunjungi url lama secara otomatis akan di redirect ke domain baru kita. Dengan fasilitas ini, kita hanya perlu membayar nama domain saja, sedangkan untuk biaya hosting adalah gratis. Kalo saya sih belum ganti domain, maklum pemula jadi masih dalam proses belajar.

Review Hacking Movie

Do not believe everything you lihat.Apalagi if you see it in
a film.Selama Hollywood years helped to disrupt the image of a hacker
the errors and absurdities masyarakat.Berbagai they display when
describe hackers silver screen, but some things can not be denied
is something close to the Hollywood interpretation kenyataan.Bagaimana
against hackers?

1.Wargames
(1984)-A film that illustrates how a teenager could
control of nuclear missiles the United States through a computer at a young rumah.Anak
thought he was controlling a game, story in this movie often disebutsebut
Mitnick.Pada Kevin terispirasi of this film in fact made before the name
Mitnick soared, writer and director did not even know the name of Mitnick as
making this film.

2.Sneakers (Universal Pictures/1992)
A group of people are often hired as a breaker
security system in a gedung.Teknik used similar to that used
hackers, including a character named telepon.Seorang tapping Whitsler could be inspired
by Joe Engressia.

3.Hackers (MGM/1995)
Angelina Jolie plays a role in this film as a sexy girl
who also likes to break into the group komputer.Ia and then trapped in
dirty conspiracy a 'security consultant'. The film is full of absurdities
such as a database view of buildings and viruses that have the form
animasi.Semua that, according to the film maker has done to effect
dramatis.Di other hand, the hacker community is often tease movie interesting things ini.Satu
is described named Cookie Monster virus can be stopped by
Cookies typing on a keyboard, a virus like that supposedly really ever
there.

4.The Net (Columbia/1995)
Sandra Bullock served as a hacker
wanita.Lucunya, the film is a link to a secret database application obtained from
a game.

5.Independence Day (20th Century Fox/1996)
Alien with the size of a spaceship months approaching the Earth and threatening to destroy all sizes dunia.Selain
ship from the chaotic logic of physics, this movie has a rarity for use
computer viruses to destroy the ship could alien.Bagaimana virus maker
fake virus in accordance with the technology owned by the aliens?

6.Trilogi Matrix (Warner Bros/1999)
Keanu Reeves as a hacker who play
found that the world is not the world but a matrix of human and machine driven by energy use as baterai.Piranti
Nmap is used in one scene in this trilogy.

7.Anti Trust (MGM/2001)
Display of the software billionaire ruler of the world
like Bill Gates as the killing penjahat.Ia software developer
Would be considered independent rival.

8.Swordfish (Warner Bros/2001)
Hugh Jackman served as a hired hacker
by conspiracy hacking penjahat.Selain excessive visuals, characters
Jackman played in this movie loved to use the technical term is not in
place.

9.Takedown (Dimension Films/2004)
Taken from the book by John Markoff and
T. Shinomura, this is the arrest of Kevin Mitnick kidah already dramatized
to display the author of the book as a hero and as a hacker Mitnick
could destroy the world just by whistling into the phone.
Hollywood certainly can not be a reference when it comes hacking, but to see hackers
Hollywood mythology can be a lot of young kids who become really interested
to hackers and find information about itu.Jika was thus impossible to open
some of them will find the essence of the hacker and become a true hacker.

Dream House? Why Not??

Houses can be regarded as one aspect of the life support that must be fulfilled by every human being. This is because most of the activities conducted by both human activities and the activities to work for a rest can be done in the house. Not only that, a person's personality can be seen from the condition of homes occupied by people, I mean words here is not whether the house is a luxury home high Uncategorized class or category of houses with a very simple house can reflect the personality of the honor Otang house , meaning here is that we can see the homeowner's personality from the aspect of cleanliness and maintenance aspects of the house.
If someone can not organize and take care of his house in such a way it is not impossible that the house could be a disaster for himself or his family. Many disaster-caused disaster from home care was not optimal, among other terpelesetnya home residents in the bathroom caused a slippery bathroom and not preserved or the fall of the occupants of the house's staircase which can be said not suitable to be used. However, the house can also be the abiding place is like a beautiful paradise with attention to design aspects of home and hospital care.
Every person who lived in tropical climates, especially in Indonesia country crossed by the equator must have dreamed of a cool house. Most people outsmart them to get the house cool by installing air conditioner (AC). For people who could be categorized earn more is not going to be a big problem for them to install air conditioning, but what about people who earn mediocre?. This can be akali with home design settings. Among other steps we can do to make ventilation, adequate ventilation. In addition, we also need to minimize the sun coming directly into our homes. Also, try as we buy or make a design house, we must consider the distance between the ceiling of the house with the floor. If the ceiling of our house has a distance from the floor far enough air circulation can lead to spin smoothly and will cause the air inside the house a bit cool, but that this aspect can also reduce heat deposits in the floor. Another aspect to consider in making semuah house cool without air conditioning that is a plant-or garden plants in the house that served to transform carbon dioxide into the usual oxygen inhaled by humans.
State of Indonesia is an archipelago that lies between two oceans. This has resulted in Indonesia in the zone of earthquake prone, it is good before we buy / make a house we must also consider the power structure of our country due to the earthquake-prone. To create a home that will stand the earthquake shocks there are several criteria that we must fulfill, among others the structure of the house that we buy / build should be strong. The foundation is a core / pole of a house can be categorized if the house was resistant to shock or not. For this we need to be carefully observant or consider this aspect, we'd better spend a little more to build a strong foundation for a house resistant to earthquakes shake houses so that we can be long lasting. Besides watching a house foundation, we must also consider the structure of the land where our homes would be built, I suggest to build a house on solid ground instead of land formerly used as paddy fields or marshes. Solid ground will be slightly more resistant to shocks when compared to the swamp lands. After watching the first aspect of the structural aspects of the home, the next aspect we need to consider is the aspect of building materials or building materials that we use as raw materials and aspects of home furniture that we use. For the material aspects of raw materials we use to build our homes should use materials made of wood, gypsum or lightweight wall materials. This serves to minimize the shock forces generated home-use of materials made of heavy materials in building houses, so the foundation can withstand shocks with stronger buildings. Aspects of furniture for writers recommend the use of furniture that blend with the house. This can take the example of houses in Japan. Most of the houses in Japan using the furniture that blend with the house so that it can reduce the shock forces during an earthquake.
For colleagues who wish to buy homes on credit either to the bank or in cash to the seller author has some tips that are used by the author's experience with families who have had several buying or selling a house. Among other things we should do a survey on housing prices we want to buy, do not we trust the words of the seller who said that this house is a cheap house with the type and type segitu segini. It would be good before buying a house, we ask for a copy of the certificate of house and home bidding by submitting certified copy of the house to the bank that we believe in, so we can compare the price of homes being offered by banks with home prices in the offer by sellers. If the bank can offer a higher price than the seller's house to offer his house, it would be nice if we had bought the house because if a destitute time we do not have the money we have nothing to lose if it sells it to banks. Also a lot is seeing or doing surveys home prices to developers of new housing or see ads listed in newspapers. Once you feel to find the right choice in a home do not rush to make transactions with the seller, it would be much better if you first check the condition of the building and check the status of ownership of the house if the house on his own behalf or on behalf of others. I suggest if you intend to buy a better home buying a house directly to homes in other words, not through brokers. Usually for metropolitan areas, brokers requested 20% fee each time a transaction. Can you imagine what price he was asking was not it?. Just imagine if I Analogikan who have a house to put brokers in house prices could have 200 million brokers offer you 240 million-an. Or even a candidate who dared to ask for a fee of more than 20%.
After I explained some of my experiences in buying and making home design can hopefully help colleagues in designing his dream house respectively. Now, depending on the innovation and imagination of colleagues to develop and create a dream house. And the dream house is not always synonymous with luxury homes that have sold billions of rupiah value. With hundreds of dollars of money we can make a house that has a value as the value of billions of dollars if we can do a bit of innovation, new innovation.

REVIEW SEMINAR SECURITY SYSTEM & LIVE DEMO HACKING 2009

Akhirnya, acara-acara yang dinantikan para pengamat IT dan para komunitas hacking underground dimulai juga. Acara yang bertajuk Seminar Security System & Live Demo Hacking 2009 dimulai, walaupun acara ini sempat molor hingga se jam. Acara yang rencananya dimulai pada pukul 09.00 WIB diundur hingga pukul 10.00 WIB. Seminar ini sendiri menampilkan narasumber dari berbagai kalangan underground nasional antara lain dari yogyafree ada family_code, ^rumput_kering^, za_2007. Sedangkan dari coder diwakili oleh kang harry beserta team coder.web.id. Selain Seminar Security System & Live Demo Hacking 2009, pada acara kali ini juga ada pertemuan antara komunitas hacking di Indonesia. Antara lain dari komunitas coder diwakili oleh staff administrator-nya akang harry, dari yogyafree reg. bandung diwakili adesurya_tkj. Selain itu juga ada rekan-rekan dari ilmu website, secure-hacklink dan comic community.

Acara dimulai dengan kata sambutan dari kang ^rumput_kering^ selaku ketua panitia dan dilanjutkan dengan kata sambutan oleh rektorat STMIK AMIK Bandung. Materi pertama disampaikan oleh kang hary (Staff Administrator) dari coder.web.id. kang harry menjelaskan tentang web hacking yang dimana kang harry menggunakan teknik sql injection dan record id. Terbukti walaupun teknik ini sudah tergolong “jadul” (sesuai dengan yang dikatakan oleh xnuxer) tetapi masih terbukti ampuh untuk melumpuhkan beberapa site di Indonesia. Bahkan site-site yang terinjeksi oleh SQL ini boleh dibilang situs-situs vital di Indonesia, antara lain ada site Ikatan Dokter Indonesia disalah satu daerah di Indonesia dan beberapa Situs Perguruan Tinggi terkenal di Indonesia (Maap sebelumnya kami tidak bisa menyebutkan daerah mana yang terinjeksi karena melanggar kode etik kami). Hal ini merupakan peringatan besar bagi admin-admin lainnya jika website yang mereka tidak ingin menjadi ajang olok-olok kan bagi para cracker-cracker yang ada. Bukan hanya di Indonesia, beberapa Site di negara Afrika juga masih bisa terinjeksi dengan teknik SQL ini.

Setelah kang harry selesai melakukan demo web hackingnya, acara dilanjutkan oleh ^rumput_kering^ dan za_2007 dengan menyajikan materi local hacking. Dengan memanfaatkan bug yang tersedia pada varian windows XP SP 1,SP 2,SP 3 hingga Windows 2003 server sampai windows 2008 Server, kita bisa mengambil alih computer lawan tanpa harus menginstal spyware maupun remote client. Sungguh teknik yang sangat berbahaya jika sampai dimanfaatkan oleh cracker, ini dikarenakan komputer kita dapat dengan mudah dikuasai oleh cracker tanpa kita ketahui karena sang cracker dapat menyerang dengan melakukan scanning IP saja. Teknik ini kira-kira menghabiskan waktu 15 menit untuk menguasai komputer target. Setelah kita menguasai computer target kita dapat meng-copy data target, melihat save password computer target bahkan untuk men-delete data computer target sendiri dapat kita lakukan dengan menggunakan teknik ini. teknik ini menggunakan teknik metasploit yang dapat kita download software metasploit di website resmi metasploit. Teknik ini dapat dicegah dengan mengaktifkan firewall dan menutup port-port yang memberi akses untuk cracker mengambil alih computer kita. Selain itu juga dengan cara melakukan update windows dan menggunakan antivirus yang selalu di update.

Setelah ^rumput_kering^, za_2007 menyelesaikan materi ini, acara dilanjutkan oleh founder yogyafree yaitu family_code, family_code membawakan materi wireless hacking WEP/WPA dengan menggunakan backtrack 3. Dengan memanfaatkan teknik ini kita dapat mengetahui password WEP suatu AP dan mengetahui IP hidden. Sungguh teknik yang sangat-sangat berbahaya karena teknik ini bisa membahayakan suatu jaringan dan menjadi peringatan besar bagi admin-admin yang mengurus jaringan disuatu daerah bebas hotspot. Dengan teknik ini sang cracker bisa merusak struktur jaringan wireless itu sendiri dan mengambil alih jaringan itu. Selain bisa masuk dan menguasai jaringan itu, sang cracker juga bisa menguasai computer target dan mengambil data-data berharga dari computer target. Teknik ini bisa diatasi dengan menggunakan WPA atau dengan menggunakan random password yang dimana system dapat mengacak password jaringan sekali dalam 5 menit sehingga cracker bisa dibuat kepusingan melakukan kegiatan crackingnya.

Setelah family_code selesai melakukan demo hacking, kegiatan diakhiri dengan diskusi antar komunitasi hacking. Disini kita bersepakat untuk lebih meningkatkan tali silaturahmi antar komunitas hacking. Komunitas hacking yang hadir dalam kegiatan itu antara lain coder.web.id, yogyafree bandung, comic, IlmuWebsite, Secure Hacklink. Selain untuk lebih meningkatkan silaturahmi, kami juga berencana untuk mengeluarkan majalah hacking bersama. Mudah-mudahan dengan pertemuan ini komunitas-komunitas hacking di Indonesia dapat bersatu dan saling support karena setelah mendengar visi dan misi dari masing-masing komunitas ternyata kami semua memiliki visi yang sama untuk menjadikan bangsa Indonesia menjadi lebih baik dan menjadi Negara yang disegani oleh dunia di bidang IT bukan menjadi Negara yang di black list oleh dunia karena kegiatan pembajakan dan cracking nya. Amin.

3G and WiMAX FUTURE COMMUNICATION TECHNOLOGY

The development of wireless technology in Indonesia, starting from the first generation of low-speed, second generation digital, and third-generation high-speed digital, bringing major changes in various aspects of social life. Therefore, wireless network technologies continue to evolve so quickly. Starting from the first-generation technology (1G), two-generation technology (2G) to third-generation technology (3G) evolve rapidly, just wireless technologies third-generation technology (3G) developed in Indonesia, Indonesian Society again shocked by technology new so-called Worldwide Interoperability for Microwave Access (WiMAX). This technology could provide speeds up to 80 Mbps. Is WiMax could be called a successor to 3G or 3G instead contender?

3G and WiMax

Currently there are two forms of 3G development, namely from the GSM (Global System for Mobile Communication) which was pioneered by the 3G Partnership Project and CDMA (Code Division Multiple Access) which was pioneered by the 3G Partnership Project 2 (3GPP2). The two technologies are incompatible and actually competing.

3G is the third generation cellular technology. Represented by the first generation AMPS technology (Advanced Mobile Phone System), which developed in the United States and TACS (Total Access Communication Service) in Europe. Technology that uses an analog system is only able to serve the voice communication. The second generation, this is the beginning of a GSM (Global System for Mobile Communication), has been using digital technology and communication can serve SMS (short message service). In the world of information technology and telecommunications, also known as broadband access technologies, whether in the form of Wired (cable) and Wireless (wireless). Wi-Fi at 2.4 GHz frequency has released its use. As we see today, the use of 2.4 GHz transmitters are rampant in Indonesia, primarily for Public Internet (Warnet) and Community (RT / RW Net), as well as small & medium companies, and education. Hotspot points in some major cities in Indonesia (in malls, airport lounges, hotels, places to eat, parks, mosques, and residential complexes) began springing up with access to paid or not. All that use Wi-Fi technology.

WiMAX (Worldwide Interoperability for Microwave Access) is a certification mark for products that pass the test match and in accordance with IEEE 802.16 standards. WiMAX is a wireless technology that provides broadband connections over long distances. WiMAX can also dikatakatan broadband technologies that have high speed access and wide reach. WiMAX is the evolution of the previous BWA technology with features that are more interesting. Besides the high data rates can be given, WiMAX also brings the issue of open standards. In this sense, although WiMAX communication devices of different vendors can still be done (not proprietary). With a large data rates (up to 70 MBps), WiMAX eligible applied for 'last mile' broadband connections, backhaul, and high-speed enterprise.

Many among the public the wrong perception by saying that WiMAX and WiFi are the same, what distinguishes WiMAX with Wi-Fi is a technical standard which joined in it. If the WiFi standard IEEE 802.11 combines with ETSI (European Telecommunications Standards Intitute) HiperLAN as technical standards suitable for WLAN, and WiMAX is a merger between the IEEE 802.16 standard by ETSI HiperMAN standards.

Video Call, "Best Application" 3G in Indonesia?

As mentioned above, that can be used for 3G data (eg internet access), voice (voice call), and video (call & streaming). The question is, What will be the best 3G application? At a certain phase, 3G operators must prepare a special session to figure out what the best application if going boom. In every country, there are different possibilities, depending on the culture of society. We have seen, how the Japanese and Korean people use 3G and how European societies less use.

In Indonesia, a campaign video calls and video streaming is very intense at the beginning of the introduction of 3G. In the meantime, as we know, the 2G era, SMS has become the best application. Cultural community for SMS was already beginning to form because the service felt more practical and cheaper. Moving a habit to SMS to a video call, the application must be accompanied by affordable rates, if not cheaper rates at least equal to the voice call.

Tariffs could be a sensitive subject in the state in economic conditions such as Indonesia. Indonesia has a population of very large, but with the market penetration of information and telecommunications (Infocom) is still small. With such market conditions, the Infocom business can choose cheaper tariff models with many customers, or the expensive fares with customers limited.

Video call is a new communication and capital can be quite sensational. But he will not be able to become best 3G application if the operator is not sensitive to read between the needs of customers and size of the pegged rate.

3G compare with other broadband access can be briefly considered less relevant. However, in the name of convergence vision, then this could be considered relevant.
3G is more popular among the people of Indonesia as a GSM mobile phone feature. (Though in fact also in the 3G CDMA 1X technology). For some advanced users (advance), this feature can be used more optimally, including access to the internet. Since the 2.5G era, they might have been using GPRS for internet access, although with limited speed.

3G Mobile and Practical

3G, with its mobile devices that have many available in Indonesia, should rely on its mobility capability and practicality. Mobility in this case, has been recognized, especially its roaming capabilities. Practicality in this case, of course related to the customer terminal or handset, proven lightweight and still able to carry in his pockets.

Existence content provider in Indonesia that reached 200 companies, should be encouraged to be more creative. Of course, it must be balanced with the cooperation scheme with the operators of mutual benefit so that (it was) able to continue to stimulate creativity. The existence of practical applications and direct touching personal needs of its customers, that's what determines the future of 3G in Indonesia. Move over, before the tide arrives. Each technology has their respective age

Prospects for WiMax and 3G developments

The presence of 3G technology in Indonesia has become adorned range broadband access services in Indonesia. Advantages in terms of mobility plus the data transmission speed faster, with a capital 3G data communications, voice, and video are promising in the future.

Finally there is the power of competition coverage, rates, and content services. In addition to large 3G market opportunities (and broadband access in general), should remain aware that Indonesia is still poor in the last mentioned earlier.

WiMax consists of two fixed WiMax services, which refers to the utilization of technology to the terminal plays remain. While Mobile WiMAX refers to broadband wireless technologies for mobile communications devices.

Excess WiMax has a data transfer speeds up to 70 Mbps and range up to 50 km. Expressed also in the early stages will be applied to fixed services in IEEE 802.16d technology. As it is known that the WiMax IEEE 802.16 standards of 802.16a / d revision to fixed, limited to 802.16e for mobility (nomadic), and 802.20 for full mobility.

Hasnul Suhaimi, president of PT Excelcomindo to trend Digit @ l expressed interest to enter the WiMax service. However, he suggested opening greater opportunities for companies to enter the service.

Alternative Technology

It Wimax will be one of the alternative technologies in the future. But the problem WiMax technology will be accepted in society and become a competitor's new 3G service was held among mobile operators? This is the question that arose following the WiMax digelarnya plan.

A market survey conducted shows of Researd Pyramid 100 cable TV companies and telecom operators around the world, at least 75 companies will use the network based on WiMax technology. Admittedly, it does not become an excuse for mobile operators to go out of business, cellular networks are built with billions of dollars, but they create opportunities through wireless broadband access as a complimentary service fixed phone or mobile network.

Sara Harris, an analyst with Strategy Analitics added, his party saw the new WiMax will boom at the beginning of the next decade. In fact, he added, Wimax users only reached 6% of the 500 million users of technology-based broadband wireless in 2010. What was stated it could happen in Indonesia. Telecommunications operators do not want 3G service with a large investment to be in vain and with the emergence of WiMax unrivaled. While expectations are expecting the BRTI WiMax service will be more focused in rural areas is of course impossible.



Application of WiMax and 3G Technology In Everyday Life

Based on the distribution segment of the use of wireless technologies, WiMAX is intended for use in segments of the Metropolitan Area Networks (MAN). MAN usually consists of a collection of LANs, and covers an area within a radius of 50 km. In terms of segment using WiMax clearly intended for the same segment with copper wire technology (eg DSL).
The problem that often occurs in the use of DSL technology to provide broadband access to users is usually called the "last-mile problems", or a problem last the distance range between the home or office users and broadband service provider networks. Which includes last-mile problem for users is the low broadband data rates due to the division of bandwidth to multiple users on the network.

The most likely solution is to use a wireless infrastructure. For wireless, the technology is commonly used WiFi network that operates at a frequency of 2.4 GHz. For a city only in Indonesia, using a WiFi solution to meet the needs of less experienced because of the very limited scope, and size of the data stream that can be skipped.

Although many predicted that WiMax will undermine the 3G market (TelecomViews research in 2009 that the mention of more than 40% of wireless broadband market will be dominated by WiMAX), 3G will not be lost and it is likely that the two technologies will live side by side. 3G is more established than WiMAX, and has many installed by various countries. Besides 3G also has the advantage of providing regional mobility in the wider coverage. 3G technology is not stagnant, and continues to grow. This year 3G base stations will be upgraded to support Dowlink High Speed Packet Access (HSDPA) which will become a standard feature for 3G mobile phones since 2006.

Meanwhile, WiMax has a bright future as seen offering opportunities for alternative telecommunication operators to offer broadband services at competitive prices to customers in the metropolitan area, and also to customers in rural areas or small cities with limited infrastructure. Combination with other technologies such as VoIP can also be new business opportunities.

What is clear in the future there is no wireless vendors or service providers that will bind themselves to one type of broadband technology, or a single network platform. What is the consumer in control. Important for consumers is how the need (to communicate over the phone, reading e-mails, download content, video streaming) can be met. Questions about "how" it needs will be met will not be disallowed.

Across Aral for WiMax

The main constraint facing the implementation of WiMAX technology is nothing but the policy issues and government regulations for wireless regulation. It still has not disappeared from our memory settings kisruhnya reviews about 3G licensing rights. Tantalizing possibility that the benefits of wireless frequency control may be making a lot of the fight, and ultimately harmful to users who pay a premium to be able to enjoy broadband services.

Implementation of Pre-WiMax technology in Aceh for example, had feared hampered by problems associated with the regulation. Based on government regulations, the use of devices that work in the WBA 5GHz frequencies require frequency licenses that can only be obtained by telecommunications operators. Users will also be charged the right to use (BHP) frequencies to be paid per year. In addition, import duties and import duties device can reach the other 30% of the price of the device. Keep in mind the implementation of a wireless frequency setting strategies that promote the public interest so that the paradigm of broadband access into something that can be enjoyed by as many people.

In addition to regulatory issues, WiMax also may take a little longer before it can be used widely by the public. Currently the price of WiMax devices still very expensive because it is still produced in limited. In addition, the devices that WiMAX technology is now on the market have not passed the certification process from the WiMAX Forum that has not guaranteed the performance and kompabilitasnya each other.


Against WiMAX Market Response Compared with 3G

3G development was carried by several vendors of telecommunications, particularly among mobile operators that currently exist, both GSM and CDMA, which is mainly supported by the manufacturers who produce 3G portable devices, both mobile phones and PDA phones. WiMAX was borne more by the industry, such as Intel and incorporated in the WiMAX Forum, including the telecommunication operators, internet access provider (ISP - Internet service provider) and device vendors, such as laptops, mobile phones, PDAs and so on.

3G, we could say, is the initiation of new services, especially for the needs of consumers who not only stop the mobile voice communications services and wireless, but also data communication services and multimedia. WiMax was, from the beginning was designed to provide wireless data communications services large capacity (wireless broadband). This WiMAX service capacity, even, can compete with DSL service and cable modem, a development many analysts predicted it would change the map of the world telecommunications industry.
