The Cisco Meraki MR12, MR16, and Z1 access point platforms are not certified for use with Cisco Wireless IP Phone 8821 and
8821-EX deployments.
Note: If an access point model is not specifically listed above, then it is not supported.
VoWLAN is currently not supported in conjunction with Cisco Aironet 1500 Series outdoor access points.
No support for any access point model operating in MESH mode.
No support for 3
rd
party access points as there are no interoperability tests performed for 3
rd
party access points.
However, the user should have basic functionality when connected to a Wi-Fi compliant access point.
Some of the key features are the following:
• 5 GHz (802.11a/n/ac)
• Wi-Fi Protected Access v2 (WPA2+AES)
• Wi-Fi Multimedia (WMM)
• Traffic Specification (TSPEC)
• Traffic Classification (TCLAS)
• Differentiated Services Code Point (DSCP)
• Class of Service (CoS / 802.1p)
• QoS Basic Service Set (QBSS)
Antenna Systems
Some of the Cisco Access Points require or allow external antennas.
Please refer to the following URL for the list of supported antennas and how these external antennas should be mounted.
