| Calling WiMAX a disaster is not fair! Mobile WiMAX falls short of expectations?
It has been reported that “Dispute erupts over bad WiMax performance” based on the report by an Australian WiMAX operator. The report cites of loss of service with direct connectivity beyond 2 Km and inbuilding coverage of only a few hundred meters from the base station.
WiMAX technology has proved itself in more than 300 trials and a number of commercial launches. Some of the recent ones are the QMAX harbour area WiMAX in Singapore, Wateen telecom in Pakistan, Tata Indicom in India and a number of operators in Latin America.
A network can not defy the laws of physics and the link performances need to be built in. First of all, the higher frequency ranges used in Australia ( nearing the extended c-band at 3.6 GHz are no help as the loss increases with square of frequency as well as distance. Secondly WiMAX base stations come in different versions such as carrier grade, Micro base stations and Pico base stations. These are with different power levels and can not deliver more than their scheduled range.
Hence it all boils down to sectorization and base station densities.
