Figure 3: Traffic Flow diagram
Each wireless device sends IP packets in the 802.11 standard to the Altitude AP. The Altitude AP uses a
UDP (User Datagram Protocol) based tunnelling protocol to encapsulate the packets and forward them
to the Summit WM series switch. In a typical configuration, access points can be configured to locally
bridge traffic (to a configured VLAN) directly at their network point of attachment. The Summit WM
series switch decapsulates the packets and routes these to destinations on the network.
The Summit WM series switch functions like a standard router, except that it is configured to route only
network traffic associated with wireless connected users. The Summit WM series switch can also be
configured to simply forward traffic to a default or static route if dynamic routing is not preferred.
Network security
The Summit WM series switch, access points, and WLAN switch software system provides features and
functionality to control network access. These are based on standard wireless network security practices.
Current wireless network security methods provide protection. These methods include:
● Shared Key authentication that relies on Wired Equivalent Privacy (WEP) keys
● Open System that relies on Service Set Identifiers (SSIDs)
● 802.1x that is compliant with Wi-Fi Protected Access (WPA)
● Captive Portal based on Secure Sockets Layer (SSL) protocol
