Altitude 450/451

Altitude 450/451 Access Points for High Speed Wireless Services

Altitude 450/451 are the next generation of Access Points (APs) that deliver very high speed wireless services using the emerging 802.11n wireless LAN technology. Altitude 450/451 are dual-radio APs that support simultaneous operation of 802.11a/n and 802.11b/g/n wireless networks. Altitude 450 comes with six (three for each band) integrated internal omni-directional antennas. 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 450/451 are designed to provide spatial diversity with 3x3 Multiple In Multiple Out (MIMO) capability that delivers wireless bandwidths as high as 150 Mbps with 20 MHz channel. With the channel bonding option the AP can deliver wireless bandwidth of 300 Mbps using a 40 MHz channel. Both models support antenna diversity for better performance, particularly in challenging multi-path environments.

Altitude 450/451 APs are designed to be fully compatible with standard 802.3af Power over Etherent (PoE) power requirements even with concurrent dual radio operation and 3x3 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 controller.

  • Flexibility to deploy in pure 802.11n environment (Greenfield) or in mixed mode in the presence of legacy (802.11a/b/g) and 802.11n clients.
  • Supports high-performance Voice over Wireless LAN with fast, Layer 3 roaming, hardware-accelerated encryption, over-the-air Quality of Service (QoS) and highly-available self-healing radio coverage
  • Provides comprehensive security with Directory-integrated link security, a rich set of authentication and access control options and wireless intrusion detection
