Extreme Networks Data Sheet Extreme Networks Altitude 4521 Cost Effective Single Radio Independent 802.11 abgn Wireless Access Point The Altitude™ 4521 is an independent, cost-effective access point. As a single radio Performance • 2x2 MIMO • 802.11 abgn (2.4 / 5GHz) • 27 dBm Max Output Power • GigE Uplink with PoE Form Factor • Single Radio • Independent AP • Wall or Ceiling Mount Features • Compact • Cost Effective • Layer 2-7 Stateful Packet Filtering Firewall • Wireless IPS • VPN Gateway • SMART RF • Internal and External Antenna Options Virtual Controller Functionality • Continues to provide service even if connectivity to controller is lost. independent AP, the Altitude 4521 can be used as a standalone AP or with a wireless controller, this AP also can become a virtual controller and control up to 24 additional Altitude 4521 Access Points. This access point is targeted at Enterprise and Campus deployments that are looking to lower the cost of deploying and operating a secure, reliable 802.11n wireless LAN (WLAN) but are also looking for a more robust solution than a pure dependent AP approach. The Altitude 4521 can continue to provide service if a connection to the controller is lost, for example by a cable cut or power failure. The Altitude 4521 is equipped with a 2x2 MIMO 802.11 abgn (2.4 and 5Ghz) band unlocked radio with a combined output power of a maximum 27 dBm. The 4521 supports local bridging and has a single Gigabit Ethernet uplink port. The device has a small form factor and is easily mounted on a wall or ceiling with included hardware. The Altitude 4521 can be powered via the Gigabit Ethernet uplink port with standard 802.3af PoE. There are two versions of the Altitude 4521, an internal integrated antenna version and an external antenna version with connectors for standard paddle antennas. Security: The AP includes a layer 2-7 stateful packet filtering firewall. AAA Radius client services, built in wireless IPS, VPN Gateway, and location based access control are also included. Deployment: The Altitude 4521 supports wireless controller autodiscovery. Upon activation it communicates with the controller and automatically downloads configuration parameters and firmware. This reduces installation, maintenance and troubleshooting costs for layer 2 and layer 3 deployments. Intelligence: The Altitude 4521 uses SMART RF to adjust power and channel selection to prevent channel overlap or co-channel interference. This is done automatically reduces the chance of human error or interference. SMART RF is a standard feature on the Altitude 4521. Direct Forwarding: The Altitude 4521 allows for direct forwarding of data traffic. That means no bottleneck at the wireless controller, which reduces latency and jitter issues for voice and video applications. Internal and External Antenna options: The Altitude 4521 comes with either internal or external antennas. The internal antenna model has a white plastic facia. The external antenna model contains two external paddle antenna connectors. Both versions support both wall and ceiling mounting, for maximum deployment flexibility. Virtual Controller Functionality: The Altitude 4521 has the capability to act as a virtual controller AP, allowing a single Altitude 4521 to control up to 24 other of the same type of AP.
