Wireless Connectivity

      Wireless Connectivity : The wireless network to be installed is based on IEEE 802.11

Backward compatibility with device based on 802.11, 802.11a and 802.11b specification.
·         802.11g network has three channels that cut down on interference.

·         802.11g uses the frequency spectrum of 2.4 GHz and can transmit at speeds of 54 Mbps giving it the distance attribute of 802.11b which is 300ft and the speed attribute of 802.11a, which is counted in the best of all.
