Wireless Point-to-Multipoint

For networks using the unenhanced radio protocols, all wireless stations be able to transmit to and receive from ALL other stations in the wireless network in order to attain good performace. However, this is not always possible due to the particular topology and terrain. KarlNet's wireless products have a special TurboCell mode in which one of the wireless nodes can be setup as a base station, providing access to the rest as "satellite" stations.

In this configuration the only requirement is that each satellite station be able to communicate with the one base station. The base station is responsible for repeating packets that need to travel between satellite stations. The performance of this approach can be improved if the base station is connected to the most heavily loaded file server or wired network access point. This is due to the fact that data flowing from one satellite to another satellite station must be repeated (retransmitted) by the base station using more of the wireless bandwidth. Data packets flowing from a satellite station to the base station are transmitted directly without the need to be repeated.

Properly configured TurboCell Point-to-Multipoint networks with a clear line-of-sight between each satellite station and the base station can reach over ten miles with optional antennas and amplifiers. Some users (with optimal terrain) have reported reliable links of well over thirty miles!
