IAP-325

The 300 Series includes the enhanced ClientMatch
technology that extends the client steering technology
with MU-MIMO client awareness. It automatically identifies
MU-MIMO capable mobile devices and steers those devices
to the closest MU-MIMO capable Aruba access point. By
grouping MU-MIMO capable mobile devices together,
the network starts taking advantage of the simultaneous
transmission to these devices, increasing its overall capacity.
These dynamic roaming policies that are based on device
types, help customers achieve the best WLAN performance
in a mixed device environment during the technology
transition period.

IOT PLATFORM CAPABILITIES
The 300 Series provides integrated Bluetooth capabilities
to enable Meridian and IoT-based location services, asset
tracking, and mobile engagement services. For expanded
• Advanced Cellular Coexistence (ACC)
– Minimizes interference from 3G/4G cellular networks,
distributed antenna systems and commercial small cell/
femtocell equipment.
• Quality of service for Unified Communication apps
– Supports priority handling and policy enforcement for
unified communication apps, including Microsoft Skype
for Business with encrypted videoconferencing, voice,
chat and desktop sharing.
• RF Management
– Adaptive Radio Management (ARM) technology automatically
assigns channel and power settings, provides airtime
fairness, and ensures that APs stay clear of all sources of RF
interference to deliver reliable, high-performance WLANs.
– The Aruba 300 Series APs can be configured to provide
part-time or dedicated air monitoring for spectrum analysis
and wireless intrusion protection, VPN tunnels to extend
remote locations to corporate resources, and wireless
mesh connections where Ethernet drops are not available.
• Intelligent app visibility and control
– AppRF technology leverages deep packet inspection
to classify and block, prioritize, or limit bandwidth for
thousands of applications in a range of categories.
• Security
– Integrated wireless intrusion protection offers threat
protection and mitigation, and eliminates the need for
separate RF sensors and security appliances.
– IP reputation and security services identify, classify, and
block malicious files, URLs and IPs, providing comprehensive
protection against advanced online threats.
– Integrated Trusted Platform Module (TPM) for secure
storage of credentials and keys.
• Intelligent Power Monitoring (IPM):
– Enables the AP to continuously monitor and report
its actual power consumption and optionally make
autonomous decisions to disable certain capabilities.
– For the 300 Series APs, the IPM power-save feature applies
when the unit is powered by an 802.3af PoE source. By
default, the USB interface will be the first feature to turn
off if AP power consumption exceeds the available power
budget. In rare cases it may be necessary to take additional
power saving measures, but in most cases, the 300 Series
APs will operate in unrestricted mode

aggregate (3×3)
– 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

POWER SOURCES AND CONSUMPTION
• 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
• Power over Ethernet (PoE): 48 Vdc (nominal)

802.3af/802.3at compliant source
– Unrestricted functionality with 802.3at PoE
– When using IPM, the AP may enter power-save mode
with reduced functionality when powered by an 802.3af
PoE source (see details on Intelligent Power Monitoring
elsewhere in this datasheet)
– Without IPM, the USB port is disabled when the AP is
powered by an 802.3af PoE source
• Maximum (worst-case) power consumption: 13W (PoE) or
12W (DC)
– Excludes power consumed by external USB device (and
internal overhead); this could add up to 6.5W (PoE) or
5.5W (DC) for a 5W/1A USB device
• Maximum (worst-case) power consumption in idle mode:
