Call Capacity
Design the network to accommodate the desired call capacity.
The Cisco Access Point can support up to 27 bi-directional voice streams for both 802.11a/n and 802.11g/n at a data rate of 24
Mbps or higher. To achieve this capacity, there must be minimal wireless LAN background traffic and radio frequency (RF)
utilization.
The number of calls may vary depending on the data rate, initial channel utilization, and the environment.

Note: It is highly recommended to use 802.11a/n if using Bluetooth.
Video Calls
Video calls over Wireless LAN will significantly reduce the potential call capacity.
Below lists the maximum number of video calls (single bi-directional voice and video stream) supported per access point /
channel for each video bit rate.
If there are two Cisco Cius communicating to each other, then that is two bi-directional voice and video streams.
