Our network utilizes 802.11 standards in the 2.4GHz frequency range. In North America, there are 11 specified channels on which to operate, each channel corresponding to a center frequency. Each channel uses 20MHz, but each channel is separated by only 5MHz. As a result, there is spectrum overlap and a resulting maximum of three usable nonoverlapping channels. Those channels are 1, 6 and 11. When two 802.11 devices use channels that overlap, one device can expect to see degradation in performance (slow speed) when the other device is very active.

For our customers who use 802.11 wireless access points or routers, it is important to have your device operating on a channel that does not overlap with our tower's channel. Occassionally we must change the tower channel to mitigate interference in the area. You should revisit this page if you have a wireless device and encounter slow speeds.
