Note: Receiver sensitivity is the minimum signal needed to decode a packet at a certain data rate.
The above values are pure radio specifications and do not account for the gain of the single integrated antenna.
To achieve 802.11n/ac connectivity, it is recommended that the Cisco IP Phone 8861 and 8865 be within 100 feet of the access
point.
