Understanding the WiMax Spectrum

Worldwide Interoperability for Microwave Access or WiMax is often compared to WiFi because both technologies are wireless. But then again, WiMax operates somewhat closely the same like cellular networks because of one very essential element – spectrum. To transmit data, most handsets or mobile phones use at least five frequencies. This makes it easier for people to communicate even at very far distances, say for example a person who lives in the US can still send or receive text messages from his or her loves ones in the Philippines or the rest of Asia. Now, WiMax operates pretty much the same thing because a list of frequencies can be used for data transmission depending on the subscriber’s location and this might include 2.3 GHz, 2.5 GHz, 3.4 GHz, 3.6 GHz, 5.4 GHz, and possibly 700 to 900 MHz.

Though it is true that there is wide range of available frequencies to be used for WiMax around the world, only two bands are considered stable and these are (a) 2.5 GHz and (b) 3.5 GHz. The 2.5 GHz band is being used in some Latin American countries such as Brazil and Mexico as well as Asian countries that include Indonesia and India. The 3.54 GHz band, on the other hand, is being used in European countries such as Austria, France and Ireland. It is also widely distributed in other parts of the globe such as China and Argentina.

700 MHz and 900 MHz bands are ideal for mobility, which is the reason why these are being considered for wireless data use. Indeed, there are still a lot of things to be worked on with the WiMax spectrum. Considering the tremendous growth of WiMax users around the world, anything is possible.
