That works for me. It'll cause trouble when there's more than one ap per tower. The cpe will tend to hunt from ap to ap casing flaky performand and outages. Then there's the small problem of using a tower to feed another small tower. If you use the same essid the two local systems will hook up to each other rather than the previous tower in line. Or use MikroTik AP's with a secondary essid that is the same on every tower just for roaming users. I've got 6000 square miles of coverage. Changing out all devices isn't an option. Most of the tower sites are very, uh, crude. Hostile may be a better word. I use my system to test gear so I can tell you guys what'll hold up and what won't, even when you do things you shouldn't. And you've missed the whole point in the first place. My solution to this problem allows the use of EXISTING infrastructure from MULTIPLE providers. Think cell phone system evolution here guys.

The farm in eastern Mississippi has about 1600 acres of contiguous farmland with gently rolling land. We used Alvarion BreezeAccess II equipment with an omni antenna at thebase station to communicate to three repeater station located at the edges of the farm. Directional panel antennas connected to BreezeAccess II 2.4 GHz radios which then went to Breezecomm radios connected to 120 degree sector antennas which broadcast into the farm to the equipment in the fields. THe farm equipment was equipped with Breezecom radios attached to omni antennas. All of these radios are frequency hopping spread spectrum radios. These have a range of about 2.5 miles talking from sector antennas to omnis. Wifi will onlu have a range of 1500 feet talking to omnis. An omni antenna is the only cost effective practical device to put on a tractor, combine or truck. The other reason we chose Alvarion is that their radios automatically handle mobility. That is, they can automatically hand over communcation from sector to sector as boudaries are crossed with loosing connection or packets of data. This system has a user data rate of 2 Mbps. The base station has a Starband satellite link to the Internet. We have also used DirecWay satellite links. The other farm is located in the Mississippi Dellta and is set up similarly with the exception being that the communication from the base station to the 9 repeater stations is handled using the Waverider 900 MHz radios. This farm consists of over 12000 acrs of cotton farmland separated by various tree lines and is roughly oval shaped with the major axis being 12 miles from side to side with the farm headquarters situated in the middle. We needed the 900 MHz radios to penetrate the trre lines to reach the Breezecom repeaters with 120 degree sector antennas to provide field coverage. THe siganl from the base station reaches almost 10 miles so the entire farm is covered by the base station. However, you must use yagi antenna precisely aimed to get reception.
