Wireless ISP Using 802.11?

netheadglenn asks: "I'm trying to set up a small ISP using wireless delivery in a developing country. I'm considering 802.11 as the protocol. Our available spectrum is from 3.7 to 4.2 Mhz. My understanding is that this works fairly well without perfect line-of-sight. We aren't limited by enforced regulation of power output - and in any case regulations here are as flexible as currency. Over here, 64kbps shared between 10 users is considered broadband. The isps simply don't offer anything better than that over dial up connections. Believe it or not, we plan to have 6 users per 64kbps. At $1000/month for 64 kilobits per second, you can see why sharing such limited bandwidth is common. We will start with serving an area within 10 miles of our server. Later we'd like to service two cities that are each about 20 miles away. What is the the absolutely least expensive solution for this?" While the idea of a wireless ISP is a good one, is 802.11 the best protocol for this kind of service?

Hu-hum : frequency

available spectrum is from 3.7 to 4.2 Mhz.

For your information, IEEE 802.11(b) products are in the 2.4 GHz range and future 802.11(g) products will be in the 5 GHz range.

So it won't work except if you develop a new version of 802.11 in the MHz (and products).

Good luck !

(frequency hopping will be very hard to do in a 0.5 MHz bandwith)
