NCAB Policy on 802.11 Wireless Access Point Deployment - 02/19/13


Overview:

Wireless in the Local Area Network using the IEEE 802.11 standard is an emerging technology. 802.11 wireless technology by nature is very easy to deploy, but very sensitive to overlapping frequencies and must be planned, deployed, and managed in a very careful and centralized fashion to ensure basic functionality, maximum bandwidth, and a secure network.

Current 802.11 wireless technology deploys a very low power signal in a frequency band divided into only 3 non-overlapping channels. The primary purpose of these channels is not so much to provide separate networks but to allow adjacent access points with slightly overlapping areas of coverage to not interfere with each other. In the normal case, it is necessary to use all three channels in an integrated fashion as a single unified network in order to achieve an optimal design. It is therefore not feasible to allow individuals to install their own access points due to the resulting signal interference and greatly degraded performance to the common wireless network.

The situation is analogous to the allocation of frequency spectrum by the FCC. If everyone was just allowed to use any spectrum at any time for any reason, the result would be chaos, and it would be impossible to use any of the spectrum for the common good. It is therefore proposed that NCAB act as the FCC of UCAR regarding 802.11 wireless networking.
