How WiMax Works

A slight difference is found between the two fastest growing internet connections i.e WiFi and WiMax. A WiMAX connection, in layman’s terms, is a faster, more extensive version of a WiFi connection. With faster speeds, greater reach and larger hosting capacity, it is seen as the solution to the oft-criticized, meager WiFi range.

This savior of the internet-using populace basically consists of two parts, a WiMax tower and a WiMax receiver. While the former, an offshoot of the phone tower concept, provides the coverage connections for an area of 3,000 square miles, the latter comes in the form of a PCMCIA card or a small receiver and antenna box.

A wired connection, high-bandwidth, of course, is a possible way to establish an Internet connection from a tower station, while a line-of-sight, microwave-based connection is the other option. This connection is the main driving force behind the ability of a WiMax connection to cater to a large area.

The non-line-of-sight service uses an antenna, installed in the computer, to establish a connection with the tower. With a frequency range of 2GHz to 11 GHz, this is the lower frequency range option but is better when it comes to protection against physical obstructions.

Similarly, the line-of-sight service uses a dish antenna, fixed and pointing straight at the WiMax tower. As is it is much more direct in nature, the connection is stronger and frequencies high, around 66 GHz, allowing for greater bandwidth and, consequently, data transmission in large amounts. The WiMax transmitting station in a line-of-sight service sends data to WiMax enabled routers or computers within a 30-mile radius, allowing for maximum range.

The last quality ascertaining factor when it comes to WiMax quality is the global area network (GAN). This, essentially, works much like a cell-phone network, with coverage in all areas of the country. Moreover, it also harbors the ability to offer cable modem service type Internet access, while also being available for portable devices such as laptops and cell-phones.
