WiMax Formed To Promote 802.16 Standard
The Original Yama writes "Intel, Nokia, Proxim, and a bunch of other companies have launched WiMax, a non-profit group founded to certify and promote the IEEE 802.16 wireless networking standard. What's interesting about this standard is that it allows "up to 31 miles of linear service area range and allows users connectivity without a direct line of sight to a base station," all at a shared speed of 70Mbps. This simultaneously blows away 3G mobile and 802.11 technologies."
Sounds great, but 31 miles? How about 50 feet though wood and concrete? Line of sight is nice, but for most interesting home networking, there's just no way.
Obviously if you have a dense population of users it becomes economical to have more base stations in the 31 mile radius, each serving a smaller zone, in the interests of extra bandwidth per user.
