QuoteIn a sense, these long-range Wi-Fi antennas would perform the same function as WiMax, a long-range wireless technology that many, including Intel, are experimenting with now. The difference is that a WiMax tower costs about $15,000 to $20,000. The long range Wi-Fi towers might only cost $700 to $800. Additionally, long range Wi-Fi could spread faster, Brewer said. The radio spectrum employed by WiMax is regulated by local telecommunications authorities. Putting up towers or offering services can require getting governmental permission.
