In Indonesia, it has not sepopuper Wimax Wi-Fi (Wireless Fidelity). But as one state licensees Wimax (Worldwide Interoperability Mobile Access), Indonesia has the authority to apply this technology in the telecommunications mobile operators who have either preparedness readiness of infrastructure and operational readiness-maintanance. Wimax wireless broadband access is expected to give a fresh breeze in the midst of the telecommunications industry competition and market needs.
Little Review about Wimax
In the session of the International Telecommunications Union (ITU), Wimax included in the IMT-2000 standard. These standards also known as third generation mobile telecommunications standard (3G) spectrum covering 2.5 to 2.69 gigahertz.
Currently undergoing WiMAX coexistence studies to ensure its status as one of the 3G technology. In fact, through his IMTAdvanced standard ITU, Wimax is ready to 4G technology.
Wimax on the side of the Manufacturer or Provider
Head of General and Public Relations Directorate General of Post and Telecommunication, Gatot S. Dewa Broto confirmed, his party has prepared a set of rules in the form of draft Regulation of the Minister of Communications and Informatics for the tender of BWA (broadband wireless access), which will begin in 2008. Tenders are intended for equipment supporting the industry to license a single block of frequencies in the 2.3 GHz band.
Wan Yi, Director of Wireless and Mobile Communications Department at China Standards Association (CCSA), said 3G Wimax satus would disrupt the balance of the mobile industry.
"The 3G technology relies on the triangular structure of W-CDMA, CDMA, and TD-SCDMA. Wimax will this affect the massive secar. All the big vendors W-CDMA and CDMA oppose this, "said Wan. Wimax is a technology that uses SOFDMA techniques, multicarrier modulation technique that uses subchannelisasi. Provider uses frequency standard for customer equipment (fixed) and mobile (normadic). Wimax different modulation techniques with CDMA CDMA which uses different code for each customer.
Wimax on the Consumer Side
Wimax technology can cover an area of about 50km, where hundreds of users will wish to share signals and channels for data transmission up to 155 Mbps.
In mobile applications, users like to use the terminal Wifi Wimax such as: notebooks, PDAs, and smartphones. Wimax utilization with the use of Wifi. A terminal can detect Wimax and Wifi network so that users will increasingly be eased because they can choose Wimax broadband (Wimax network) or wireless hotspot (for network Wifi / Wireless LAN).
Synergy Wimax-Wifi-Cell
Wifi (Wireless LAN) is a wireless communication network via the LAN computer. Its scope is limited to certain areas, so called hotspots. Services provided can be varied, like LAN applications such as email, internet, intranet, messaging, music / video streaming and other IP service base.
When Wifi Wimax combined with the obvious implementation will accelerate and expand its use, more secure because it can be a QoS (Quality of Service), more reliable, and rich in new services.
Synergies between the mobile WiMAX combines cable and wireless networks, services and terminals. In general, the concept of convergence in telecommunications involves three aspects, namely: devices, services, and network.
Wimax generally introduced as a solution that offers access to multi-access, for example: WiMAX to complement the existing networks (2G/3G and WiFi). Wimax will automatically lead to the emergence of competition from 3G bearers
3G service is mobile communication service that promises up to 384 Kbps bandwidth peningkakan when accessed in a state of motion (normadic) while for the vehicle moving speed 128 Kbps and 2 Mbps sampao rest. GSM-based 3G technology (WCDMA) and CDMA (CDMA 2000). Thus advantages of speed and Wimax is a more attractive service than the 3G. However, the ability mobilitynya 3G is still more superior because it uses the node B, which of course can cover a wider.
