Node-to-node Distance and Angle CalculationArrowSpan 802.11a & 802.11b Antenna
Length: 304m (1000ft) with -63.8dBm [54Mbps] 18dBm (54Mbps output power) + 8dBi antenna = 26dBm 26 - 93.7 (304m 5.8GHz open space loss) + 8 (receiving antenna gain) = -59.7dBm Minimum link sensitivity: -67dBm for 54Mbps
Height: 22.6m (74ft) with maximum 8dbi gain from Antenna Total 45.6m (149ft) of coverage [13°] with 8dbi gain from Antenna. - 3dbi RF loss with great than maximum height
