Aruba 550 Series Campus Access Points
802.11ax wireless for extreme-density mobile and IoT deployments
With the increasing number of mobile and IoT devices reliant on wireless access, networks must be capable of accommodating
capacity needs and a diverse mixture of device types, applications and services.
The Aruba 550 Series campus access points with 802.11ax technology are designed to deliver very high performance and
throughput in environments where mobile and IoT density is a growing concern. The 550 Series uses 802.11ax features to
simultaneously serve multiple clients and prioritize different types of traffic to increase data rates for both individual applications
and devices, and the overall network.
The 550 Series includes support for all mandatory and several optional 802.11ax features, which include up- and downlink OFDMA
with up to 37 resource u
MIMO), 8x8 MIMO with up to eight spatial streams in the
5GHz band, and 4x4 MIMO with up to four spatial streams in 2.4GHz, channel bandwidths up to 160MHz (in 5GHz; 40MHz in
2.4GHz), and 1024
The 550 Series supports maximum data rates of 4.8Gbps in the 5GHz band and 1,150Mbps in the 2.4GHz band (for an aggregate
peak data rate of 5.95Gbps). Each AP supports up to 1024 associated client devices per radio, making the high-end 802.11ax 550

density environments, such as large public venues, higher education, hotels and enterprise offices.
In addition to 802.11ax standards, the 550 Series supports unique features such as Aruba ClientMatch radio management and
additional radios for location services and IOT applications. With 4 times the capacity of 802.11ac APs and universal IoT connectivity,
the 550 Series delivers an unsurpassed user experience for today’s all-wireless digital environments.

Enhanced Performance
To better support growing client density, the 550 Series uses two key new features within 802.11ax that support multi-user
connectivity and enhanced efficiency. The

user capabilities, a channel can be divided in

originally introduced in 802.11ac. This improves network capacity by allowing
In addition to the standard 802.11ax capabilities, with the optional tri-radio operating mode, the 5GHz radio is split up into two
independent 4x4 MIMO radios with up to four spatial streams each. This enables even higher numbers of simultaneously connected
client devices.
To optimize endpoint connections Aruba’s ClientMatch technology will automatically detect and classify mobile devices with
common characteristics, group these devices, and match them with the best AP’s and radios to enhance the performance of the
network. For example, all 802.11ax capable devices will be grouped onto available 11ax AP and radios, so that the performance
benefits of Orthogonal Frequency Division Multiple Access (OFDMA) are maximized. This means increased network performance
and a boost in network capacity.

Smart Power Management
As higher performance 802.11ax access points handle a greater number of devices and traffic, they will drive the need for more
power consumption. To offset these demands, Aruba NetInsight includes a feature called GreenAP which allows the 550 Series
access points to draw less power when it’s not being used, such as evenings when the buildings are empty.
Aruba Intelligent Power Monitoring (IPM) allows for the 550 Series to operate even when your existing switches do not provide
enough PoE. This enables IT to gradually upgrade their switching infrastructure by allowing the APs to operate even if 802.3bt is
not supported in the existing swi
enables the AP to continuously monitor and report its actual power
consumption and optionally make autonomous decisions to disable certain capabilities based on the amount of power needed to
boot and operate.
Another unique Aruba feature in the 550 Series AP is Aruba Smart PoE. This allows for both Ethernet ports on the AP to draw power
from existing switch infrastructure. Smart
enables to configure two PoE ports to either aggregate their power (more power
available) or use one as a redundant PoE power.
IoT and location Ready
The New 802.11ax technology also provides unique benefits for IOT devices. The features range from dedicated channels in OFDMA
to support the simultaneous transmission of low

battery life savings.
In addition, the 550 Series support an integrated Bluetooth 5 and Zigbee radio, as well as a USB port for maximum flexibility, which
provides secure and reliable connectivity for IOT devices to support a wide range of location services.
