Typical areas of application of WiMAX are as given below:
1. Residential and SOHO High Speed Internet Access. The main contenders for residential and SOHO market are the DSL, and Cable Internet technologies. These technologies have already established a market presence, and have proven track record in meeting the demands of the residential and SOHO customers. WiMAX provides an alternative to existing access methods, where it is not feasible to use DSL or Cable Internet. Typical application will be in remote areas where it is not economically feasible to have a DSL or Cable Internet. WiMAX is also expected to be more reliable due to wireless nature of communication between the customer premises and the base station. This is particularly useful in developing countries where the reliability and quality of land-line communications infrastructure is often poor.
2. Small and Medium Business. The WiMAX WBA is well suited to provide the reliability and speed for meeting the requirements of small and medium size businesses in low density environments. One disadvantage of WiMAX is the spectral limitation, in other words limitation of wireless bandwidth. For use in high density areas, it is possible that the bandwidth may not be sufficient to cater to the needs of a large clientele, driving the costs high.
3. WiFi Hot Spot Backhaul: Another area where WiMAX connectivity is for WiFi hot spots connectivity. As of now, there have been several WiFi hotspots and a WiMAX backhaul provides full wireless solution to these wireless networks.
Compare WiMAX with WiFi:
The mail distinction between WiFi and WiMAX is speed and coverage distances. WiFi has a typical bandwidth of 2MBps whereas WiMAX can have a bandwidth of up to 75MBps. The coverage distances also differ to a great extent. A WiFI hotspot typically covers a few hundred feet radius (fraction of a kilometer) whereas a WiMAX can practically cover up to a distance of 10 kilometers (6 miles). One probable application of MAN is to link several WiFi networks together with WBA (Wireless Broadband Access) using WiMAX technology.
Current trends in WiMAX usage:
The technology is relatively new, and several vendors are coming up with the support infrastructure. Intel and Fujitsu are among the leading providers of WiMAX compliant SoC chips. The SoCs’ can be used to make Customer Premise Equipment (CPE) that are used to access WBA base stations. It is expected that 802.16 compliant systems would be in place by the end of 2005.
