WiMax Hype

All this is theorically, 40Mbps is a hype, the real speed per user (the bandwith is always split and limited by QoS functions) is about 0.4Mbps to 1Mbps (quality and coverage will decrease dramatically the speed because phisical issues), also the price per conection will have a role in the delivered Troughput (more you want, the more you pay if this is posible). Another issue is the fact that the price of a UMTS RBS or BTS and WiMax AWC is the about the same price at this moment, but the frequency band in which this will work (2.5 GHz), will make the carriers to spend more money then UMTS or CDMA carriers with lowers frequencies. Indoor coverage will be a hughe disapointment for many CDMA or WCDMA users. This will be a huge backward in real life deployment of networks but seems nobody wants to talk about it. Remeber, this technology is base on a patched fixed standar, Handover will be a real headache for users and carriers (NO REALTIME APLICATIONS WILL BE SUITED FOR THIS TECHNOLOGY). This will make the carriers to spend hard time trying to get back the investment (MORE hardware require more money investement, but if people in ther house are not happy = less contracts). And finally, the Sprint experience will scare many others telcos observers (everybody is at expectition for Sprint). THEY URGENTLY NEED 700 MHz to really have a nice network and be able to compete to others 3G technologies. NO OTHER WAY IS LEFT. I see the whole thing as a strategy to push users for a CDMA EV-DO/WiMax card/Handset contract in order to increase CDMA presence (WiMax for fix locations usage and CDMA for mobility).
