From Wikipedia, the free encyclopedia. In the United States and Canada, a regional sports network (RSN) is a cable television channel (many of which are also distributed on direct broadcast satellite services) that presents sports programming to a local market or geographical region.
[edit]. In an IEEE 802.11 system, RSSI is the relative received signal strength in a wireless environment, in arbitrary units. RSSI is an indication of the power level being received by the antenna.Therefore, the higher the RSSI number, the stronger the signal.or the most part, 802.11 RSSI has been replaced with received channel power indicator (RCPI). RCPI is an 802.11 measure of the received RF power in a selected channel over the preamble and the entire received frame, and has defined absolute levels of accuracy and resolution.
