With a maximum concurrent data rate of 4.8 Gbps in the 5 GHz band and 1,150 Mbps in the 2.4 GHz band (for an
aggregate peak data rate of 6 Gbps), the 550 Series Access Points deliver very high performance 802.11ax access for
mobile and IoT devices in indoor environments for any growing enterprise environment. The very high performance
and extreme density 802.11ax 550 Series Access Points support all mandatory and several optional 802.11ax features,
which include up- and downlink Orthogonal Frequency Division Multiple Access (OFDMA) with up to 37 resource units
for increased user data rates and reduced latency, up- and downlink Multi-User Multiple Input Multiple Output (MU-
MIMO) for improved network capacity with multiples devices capable to transmit simultaneously, 8x8 MIMO with up
to eight spatial streams (8SS) in the 5 GHz band and 4x4 MIMO with up to four spatial streams (4SS) in the 2.4 GHz
band, channel bandwidths up to 160 MHz (in 5 GHz; 40 MHz in 2.4 GHz), and up to 1024-QAM modulation. Each AP
supports up to 1,024 associated client devices per radio and has eight internal dual band antennas. In addition to
802.11ax standard capabilities, the Wi-Fi 6 550 Series supports unique features like Aruba ClientMatch radio
management and additional radios (Bluetooth 5 and Zigbee) for location services, asset tracking services, security
solutions and IoT sensors, as well as ArubaOS 8 features like Aruba Activate and AirMatch with machine learning
technology to automatically optimize the wireless network performance.
