Aruba Wireless AP555 Dual-Band Indoor Gigabit Access Point (JZ356A)

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 first is Orthogonal Frequency Division Multiple Access (OFDMA) and the other is multi-user - multiple input multiple output (MU-MIMO).

• Multi-user transmission with downlink and uplink OFDMA - OFDMA increases user data rates and also reduces latency, especially for a large number of devices with short frames or low data-rate requirements, such as voice and IOT devices. By providing multi-user capabilities, a channel can be divided in the frequency domain, and multiple transmissions can be carried simultaneously. OFDMA is particularly effective in raising network efficiency and capacity where there are many devices, short frames, or low data-rate streams

• Multi user transmission with downlink and uplink multi-user MIMO - MU-MIMO is another multi-user capability, originally introduced in 802.11ac. This improves network capacity by allowing multiple devices to transmit simultaneously.

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.
