AvaLAN Wireless Systems designs, builds and sells outdoor wireless Ethernet bridges and networks. AvaLANs products are specifically built to be robust and reliable to meet the needs of the security marketplace. AvaLANs products use narrow bandwidth and high power to produce the longest range wireless Ethernet links on the market today. Our radios provide a large number of discrete channels and have built-in frequency intelligence to provide robust immunity to interference. The 900 MHz products use a low frequency that can penetrate through trees and building walls. The 5.8 GHz products operate in a relatively quiet spectrum that has low interference and noise, providing transmission distances of 30 miles or more, even in high RF noise environments.
