I found this interesting site about community wireless providers – defiantly one of the interested readings at last time.

I recommend to take a look at http://www.cwirp.ca/

The Community Wireless Infrastructure Research Project (CWIRP) project brings together an interdisciplinary team of academic researchers and community and government partners to engage in in-depth case studies of public/community-based ICT initiatives in order to document and assess the various models, best practices and benefits of public ICT infrastructure provision in Canada.

Time division multiple access (TDMA)

Technology used for example in GSM networks, Motorola Canopy, DVB, etc. This is a smart and sophisticated system sharing one frequency supporting multiple users on an accrual basis. Each of the users, who share the frequency, has a dedicated time slot. This is in very rapid succession of individual transmissions creates a transmission hannel, called timeslots, used for communication between client and base station unit (access point).

** To get full AirMax performance, all radios have to be AirMax products.

** AirMax is not compatible with AirOS 3.x or any other manufactures’ products or OS.

** Non-AirMax UBNT products and other manufactures’ products cannot be upgraded to an AirMax product.

If you have AirMax on, and you take note of proper installations signals and fade margins, then you can reach in upwards of 100 user’s. However you must have the bandwidth to support this.
