ARUBA 300 SERIES ACCESS POINTS

• Available channels: Dependent on conigured  

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)

• Supported modulation types:

 

802.11b: BPSK, QPSK, CCK

 

802.11a/g/n/ac: BPSK, QPSK, 16-QAM, 64-QAM, 256-QAM

• Transmit power: Conigurable in increments of 0.5 dBm
• Maximum (conducted) transmit power (limited by local 

regulatory requirements):

 

2.4GHz band: +18 dBm per chain, +21 dBm  

aggregate (2x2)

 

5GHz band: +18 dBm per chain, +23 dBm  

aggregate (3x3)

 

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

• Maximum ratio combining (MRC) for improved  

receiver performance

• Cyclic delay/shift diversity (CDD/CSD) for improved 

downlink RF performance

• Short guard interval for 20MHz, 40MHz and  

80MHz channels

• Space-time block coding (STBC) for increased range and 

improved reception

• Low-density parity check (LDPC) for high-eiciency error 

correction and increased throughput

• Transmit beam-forming (TxBF) for increased signal 

reliability and range

• Supported data rates (Mbps):

 

802.11b: 1, 2, 5.5, 11

 

802.11a/g: 6, 9, 12, 18, 24, 36, 48, 54

 

802.11n (2.4GHz): 6.5 to 300 (MCS0 to MCS15)

 

802.11n (5GHz): 6.5 to 450 (MCS0 to MCS23)

 

802.11ac: 6.5 to 1,300 (MCS0 to MCS9, NSS = 1 to 3 for 

VHT20/40/80

• 802.11n high-throughput (HT) support: HT 20/40
• 802.11ac very high throughput (VHT) support:  

VHT 20/40/80

• 802.11n/ac packet aggregation: A-MPDU, A-MSDU

• AP-304/IAP-304: Three RP-SMA connectors for external 

dual band antennas. Worst-case internal loss between 

radio interface and external antenna connectors (due to 

diplexing circuitry): 0.8dB in 2.4GHz and 1.6dB in 5GHz.

• AP-305/IAP-305: Three integrated dual-band downtilt 

omni-directional antennas for 3x3 MIMO with maximum 

antenna gain of 3.9dBi in 2.4GHz and 5.4dBi in 5GHz. 

Built-in antennas are optimized for horizontal ceiling 

mounted orientation of the AP. The downtilt angle for 

maximum gain is roughly 30 degrees.

 

The maximum gain of the combined (summed) antenna 

patterns for all elements operating in the same band is 

5.4dBi in 2.4GHz and 7.6dBi in 5GHz.

• One 10/100/1000BASE-T Ethernet network interface (RJ-45)

 

Auto-sensing link speed and MDI/MDX

 

802.3az Energy Eicient Ethernet (EEE)

• USB 2.0 host interface (Type A connector)
• Bluetooth Low Energy (BLE) radio

 

Up to 3dBm transmit power (class 2) and -92dBm 

receive sensitivity

 

Integrated antenna with roughly 30 degrees downtilt 

and peak gain of 2.3dBi (AP-304/IAP-304) or 3.4dBi  

(AP-305/IAP-305)

• Visual indicators (multi-color LEDs): for System and  

Radio status

• Reset button: factory reset (during device power up)
• Serial console interface (proprietary; optional adapter  

cable available)

• Kensington security slot

• The AP supports direct DC power and Power over 

Ethernet (PoE)

• When both power sources are available, DC power takes 

priority over PoE

• Power sources are sold separately
• Direct DC source: 12Vdc nominal, +/- 5%

 

Interface accepts 2.1/5.5-mm center-positive circular 

plug with 9.5-mm length
