AP-228 SPECIFICATIONS
2.4-GHz (600 Mbps max) and 5-GHz (1.3 Gbps max) radios, each with 3x3 MIMO and three combined, diplexed external antenna connectors.


WIRELESS RADIO SPECIFICATIONS
AP type: Indoor, dual radio, 5 GHz 802.11ac and 2.4 GHz 802.11n •In addition to 802.11n data rates, the 2.4-GHz radio supports 802.11ac data rates using 256-QAM modulation. This gives TurboQAM-enabled clients a 33% boost above the maximum supported data rate.
Software-configurable dual radio supports 5 GHz and 2.4 GHz
3x3 MIMO with three spatial streams and up to 1.3 Gbps wireless data rate
Supported frequency bands (country-specific restrictions apply): •2.4000 GHz to 2.4835 GHz
•5.150 to 5.250 GHz
•5.250 to 5.350 GHz
•5.470 to 5.725 GHz
•5.725 to 5.850 GHz
Available channels: Dependent on configured regulatory domain
Dynamic frequency selection (DFS) optimizes the use of available RF spectrum
Supported radio technologies: •802.11b: Direct-sequence spread-spectrum (DSSS)
•802.11a/g/n/ac: Orthogonal frequency-division multiplexing (OFDM)
•802.11n/ac: 3x3 MIMO with up to three spatial streams
Supported modulation types: •802.11b: BPSK, QPSK, CCK
•802.11a/g/n: BPSK, QPSK, 16-QAM, 64-QAM
•802.11ac: BPSK, QPSK, 16-QAM, 64-QAM, 256-QAM
Transmit power: Configurable in increments of 0.5 dBm
Maximum (aggregate, conducted total) transmit power (limited by local regulatory requirements): •2.4-GHz band: +23 dBm (18 dBm per chain)
•5-GHz band: +23 dBm (18 dBm per chain)
Advanced Cellular Coexistence (ACC) feature to effectively deal with interference from cellular systems
Maximum ratio combining (MRC) for improved receiver performance
Cyclic delay diversity (CDD) for improved downlink RF performance
Short guard interval for 20-MHz, 40-MHz and 80-MHz channels
Space-time block coding (STBC) for increased range and improved reception
Low-density parity check (LDPC) for high-efficiency error correction and increas
