Available bands and channels: Dependent on configured regulatory domain (country)
Dynamic frequency selection (DFS) optimizes the use of available RF spectrum in the 5GHz band
Including Zero-Wait DFS (ZWDFS) to accelerate channel changes.
Transmit power: Configurable in increments of 0.5 dBm
Maximum (aggregate, conducted total) transmit power (limited by local regulatory requirements):
Per radio/band (2.4GHz / 5GHz / 6GHz): +24 dBm (18dBm per chain)
Note: conducted transmit power levels exclude antenna gain. For total (EIRP) transmit power, add antenna gain.
Advanced Cellular Coexistence (ACC) minimizes the impact of interference from cellular networks
Ultra Tri-Band (UTB) enables ultimate flexibility in 5GHz and 6GHz channel selection without performance degradation
Maximum ratio combining (MRC) for improved receiver performance
Cyclic delay/shift diversity (CDD/CSD) for improved downlink RF performance
Space-time block coding (STBC) for increased range and improved reception
Low-density parity check (LDPC) for high-efficiency error correction and increased throughput
Transmit beam-forming (TxBF) for increased signal reliability and range.
Wi-Fi antennas
AP-655: Integrated downtilt omni-directional antennas for 4x4 MIMO with peak antenna gain of 4.6dBi in 2.4GHz, 5.2dBi in 5GHz and 5.4dBi in 6GHz. Built-in antennas are optimized for horizontal ceiling mounted orientation of the AP. The downtilt angle for maximum gain is roughly 30 to 40 degrees.

• Combining the patterns of each of the antennas of the MIMO radios, the peak gain of the combined, average pattern is 3.6dBi in 2.4GHz, 3.1dBi in 5GHz and 3.7dBi in 6GHz.

Power sources and power consumption
The AP supports various power modes depending on the available power source(s) and configuration

• With IPM disabled, the AP may apply some static restrictions, see tables below
• With IPM enabled, the AP will start up in unrestricted mode but may dynamically apply restrictions depending on the available power budget and actual consumption. The feature restrictions and order in which these get applied are configurable
• When powered by direct DC power, the AP operates without restrictions
• Powering the AP from a single 802.3af (class 3 or lower) POE source is not supported (except for AP staging), regardless of IPM status

Maximum (worst-case) power consumption (without / with a USB device attached):

• DC powered: 36.0W / 42.5W
• POE powered: 40.3W / 46.5W
• This assumes that up to 5W is supplied to the attached USB device

Maximum (worst-case) power consumption in idle mode: 14.3W/20.2W (DC) or 16.9W/22.7W (POE)
Maximum (worst-case) power consumption in deep-sleep mode: 2.4W (DC) or 4.0W (POE)
Mounting details
A mounting bracket has been pre-installed on the back of the AP. This bracket is used to secure the AP to any of the mount kits (sold separately); see the 650 Series Ordering Guide for details.
