Wireless standards for long distance Networks

Hello everyone,

I am doing some research about the wireless networks for long distance
communication and access. I am interesting in how wireless technolocy can be
use to bring internet access to remote locations and third world countries

Are there any standards in develop or already available that where one can
access a wireless network from say several miles away? (similar to Tv and
radio networks)

thanks in advance

You might try Google and search for WiMax, WISP, Alvarion, Redline,
smartBridges, WaveRider, Canopy. The first term is a kind of wireless
technology, the second refers to wireless internet providers, the others
are brands of wireless equipment.

I've been told that the most important problem with 3rd world wireless
infrastructure is theft of the equipment. I heard a speaker describe
how he setup a radio system in Guatamala, mostly for wireless VoIP
telephony. They built a small village around the radio site, located
on a high mountain, where nobody wanted to live. They then "hired"
the transplanted residents to take care of the radio site, which meant
keeping anyone from stealing the equipment. Incidentally, they went
with 900MHz because it penetrates foliage better.

Oh yes. 802.16 (WiMax) is designed for such a centralized system.
Central hub, NLOS, 4-6 miles typical, satellite link. No hardware
quite yet except on 3Ghz (for EU) thanks to Intel being late on chips.
I suggest you talk to Alvarion.

One catch... New hardware is expensive.

Thanks Roger I did a quickie search on WiMax and I believe I hit the
jackpot.
I'll try the others soon.
