Altitude 451 is the next generation of Access Point (AP) that delivers very high speed wireless services using the emerging 802.11n wireless LAN technology. Altitude 451 is dual-radio AP that supports simultaneous operation of 802.11a/n and 802.11b/g/n wireless networks. Altitude 451 is equipped with three RP-SMA connectors for external antennas and comes with a set of three dual band paddle antennas.The radios and antennas in Altitude 451 are designed to provide spatial diversity with 3 x 3 Multiple In Multiple Out (MIMO) capability that delivers wireless bandwidths as high as 150Mbps with 20MHz channel. With the channel bonding option the AP can deliver wireless bandwidth of 300Mbps using a 40MHz channel. It supports antenna diversity for better performance, particularly in challenging multi-path environments.Altitude 451 AP is designed to be fully compatible with standard 802.3af Power over Ethernet (PoE) power requirements even with concurrent dual radio operation and 3 x 3 MIMO configuration. This capability enables customers to easily deploy the AP in the existing PoE switch infrastructure, without having to allocate two PoE ports per AP and double the cable runs to each AP.Altitude APs are managed centrally by Summit WM controllers while enabling user traffic to be bridged locally at the AP or tunneled to the controller. The flexibility to locally bridge the user traffic at the AP enables deployment of high speed 802.11n service without being forced to upgrade the minimize
