IEEE 802.16

WiMAX, the wireless internet of the future

We talk about Wi-Fi? Well, let’s brush up what it is. Today, the standard for wireless Internet is the Wi-Fi, which is summarized in the following: an antenna array radiates a signal and equipment with this technology that are within the range of antennas Wi-Fi (called “Hot spots”) can connect to wireless Internet, a transfer rate bandwidth (the maximum allowed for that system is 54 Mbps).

Thanks to this feature, in certain parts of the world this technology had extensive development, which led to forming a kind of social movement, with users communities, each with its antenna trying fully cover a sector of a community or neighborhood. Why is it necessary to have several members of a community for this? Because the Wi-Fi antennas have a maximum range of 150 meters, which in practice is reduced to about 90.

What is Wimax

And here is the point of the matter: the new WiMax technology proposes higher speeds (up to 124 Mbps) and, most important, each antenna of this system expands its range of 150 meter to 44 miles. The thing obviously changed. Even more so when you consider that when WiMAX is in full swing, the promise is that the cost of installation of antennas and equipment is lower than the current Wi-Fi.

With the promised range of 50 to 70 kilometers, another panorama opens. Wireless Internet no longer be an exclusively urban attraction (a situation that is unavoidable and necessary to put antennas each 90 meters), on the other hand, Internet could be brought into suburban and rural areas where cable installation is even more difficult by the low number of users. For this reason it is that India is one of the major stakeholders in the WiMAX, to bring broadband (and telephony, and associated services) low cost to more distant areas.

Some technical details of the WiMAX

  • Name: WiMAX comes from “Worldwide Interoperability for Microwave Access”. The name is the “mask” of the technical definition of the standard 802.16a, a new wireless standard that was approved in 2001 by the WiMAX Forum, which brought together more than 60 companies in the sector.
  • High bandwidth: A base station can simultaneously allow access to more than 60 clients with T1-type connectivity / Y1 hundreds of homes with DSL connections.
  • Protocol independence: can carry IP, Ethernet, ATM and more.
  • Services added: can transmit Voice over IP (VoIP), data, video, etc.
  • Compatibility: supports phone masts third generation (3G) (called smart antennas) that constantly point to the receiver, although moving.

The future of WiMAX

As mentioned, members of the working group of the IEEE 802.16 standard are investing in the development of portability and mobility. The IEEE 802.16y will fixed correct but also portable and mobile base specification to enable not only the operation. The working groups of the IEEE and IEEE 802.16g 802.16f are responsible for the management interfaces of fixed and mobile operation.

What is Wimax

In this scenario fully in motion, users can move data while accessing broadband or multimedia session streaming. All these features will help make that WiMAX is an even better solution for Internet access in developing countries.

How it works WiMAX?

Internet provider sets up a WiMAX base station to few Km. from your city. To access this service, you just need a computer suitable for WiMAX or to upgrade your current computer to get the necessary support.

Each user will have a special code to obtain access to the station-base. The base station will transmit data from the Internet to your computer (with a current modems that potentially higher speed).

The cost of this service will be much lower than the current high-speed Internet because the provider need not use cables or have facilities to provide service.

In the case of a home network, things would not be very different. The WiMAX base station-send data to a WiMAX router, which send data to computers on your network. You can also combine WiFi and WiMAX by having the router send data to computers via Wi-Fi.

What is Wimax

WiMAX is not only a threat to providers of DSL and cable Internet. The WiMAX protocol is designed to provide different data transmission methods, one of them is the VOIP (Voice Over Internet Protocol).

VOIP allows even international via an Internet connection broadband local calls, long distance and. If the WiMAX service does become a consumer service, using VOIP can increase increasingly. Virtually anyone with a laptop could make VOIP calls.
