Wireless AP Overview
The Wireless AP is a wireless LAN access point that uses the 802.11 wireless standards (802.11a+b/g)
for network communications. The Wireless AP bridges network traffic to an Ethernet LAN. The
Wireless AP is provided with proprietary software that allows it to communicate only with the Summit
WM Controller.
The Wireless AP physically connects to a LAN infrastructure and establishes an IP connection to the
Summit WM Controller. The Wireless AP has no user interface—instead the Wireless AP is managed
through the Summit WM GUI. The Wireless AP’s configuration is centrally managed and applied from
the Summit WM Controller. In addition, the Summit WM Controller provides centralized management
(verification and upgrade) of the Wireless AP firmware image.
All communication with the Summit WM Controller is carried out using a UDP-based protocol, which
encapsulates IP traffic from the Wireless AP and directs it to the Summit WM Controller. The Summit
WM Controller decapsulates the packets and routes them to the appropriate destinations, while
managing sessions and applying policy.
Wireless AP Models
The Wireless AP has two models:
●
Altitude 350-2 Int. AP (15958) – Internal antenna, internal dual (multimode) diversity antennas
●
Altitude 350-2 Detach. (15939) – External antenna (dual external antennas), RP-SMA connectors
