1,733 Mbps wireless data rate to up to three MU-MIMO
capable client devices simultaneously
• 2.4 GHz: Four spatial stream Single User (SU) MIMO for up
to 800 Mbps wireless data rate to individual 4x4 VHT40
client devices (600 Mbps for HT40 802.11n client devices)
• Support for up to 256 associated client devices per radio,
and up to 16 BSSIDs per radio

available RF spectrum
• Supported radio technologies:

- Note: conducted transmit power levels exclude antenna
gain. For total (EIRP) transmit power, add antenna gain
• Advanced Cellular Coexistence (ACC) minimizes
interference from cellular networks

receiver performance
• Cyclic delay/shift diversity (CDD/CSD) for improved
downlink RF performance
• Short guard interval for 20 MHz, 40 MHz, 80 MHz and
160 MHz channels
• Space-time block coding (STBC) for increased range and
improved reception
• Low-density parity check (LDPC) for high-eciency error
correction and increased throughput
• Transmit beam-forming (TxBF) for increased signal
reliability and range
• Supported data rates (Mbps):

WI-FI ANTENNAS
• AP-334/IAP-334: Four RP-SMA connectors for external
dual band antennas. Internal loss between radio
interface and external antenna connectors (due to
diplexing circuitry): 2.3 dB in 2.4 GHz and 1.2 dB in 5 GHz.
• AP-335/IAP-335
- Four (vertically polarized) integrated 2.4 GHz downtilt
omni-directional antennas for 4x4 MIMO with peak
antenna gain of 4.3 dBi per antenna.
- Each 5 GHz radio chain has both a vertically and a
horizontally polarized antenna element; AP software
automatically and dynamically selects the best set of
elements for each data packet transmitted or received.
- Four integrated vertically polarized 5 GHz downtilt omni-
directional antennas for 4x4 MIMO with peak antenna
gain of 5.4 dBi per antenna
- Four integrated horizontally polarized 5 GHz downtilt
omni-directional antennas for 4x4 MIMO with peak
antenna gain of 4.2 dBi per antenna
- Built-in antennas are optimized for horizontal ceiling
mounted orientation of the AP. The downtilt angle for
maximum gain is roughly 30 degrees.
- Combining the patterns of each of the antennas of the
MIMO radios, the peak gain of the eective per-antenna
pattern is 2.6dBi in 2.4 GHz and 2.5 dBi (vertical) or
2.1 dB (horizontal) in 5 GHz.
