By leveraging the 6 GHz band, Aruba 650 Series Campus APs delivers peak performance and far greater capacity than previous generations of Wi-Fi. With up to 1200 MHz of new channels, capacity is nearly tripled – so you can meet growing demand due to bandwidth-hungry video, increasing numbers of client and IoT devices and growth in cloud. Unique to Aruba, the 650 Series includes ultra tri-band filtering to minimize channel interference and dual configurable 5 Gbps ethernet ports to eliminate coverage gaps, provide greater resiliency, and deliver fast, secure connectivity.

  • Comprehensive tri-band coverage across 2.4GHz, 5GHz, and 6GHz to deliver up to 7.8Gbps combined peak datarate
  • 4x4 MIMO radios to deliver peak performance and increased capacity using MU-MIMO and OFDMA (uplink and downlink for both)
  • Up to seven 160MHz channels in 6GHz support low-latency, bandwidth-hungry applications like high?definition video and augmented reality/virtual reality applications 
  • Unique ultra tri-band filtering enables 5GHz and 6GHz to operate without restrictions or interference
  • High availability with configurable 5 Gbps dual Ethernet ports for hitless failover of ethernet and power 
  • Built in GPS receivers and intelligent software enable APs to self-locate and act as reference points for accurate indoor location measurements.

The 650 Series APs are designed to take advantage of the 6GHz band, which translates into far greater speeds, wider channels for multi-gigabit traffic, and less interference. The three 4x4 MIMO radios of the platform deliver a combined peak data rate of up to 7.8Gbps.

BandChannel bandwidth Peak data rate 6GHz 160MHz 4.8Gbps 5GHz 80MHz 2.4Gbps 2.4GHz 20MHz 574Mbps Total 7.8Gbps

Advantages of 6GHz

Wi-Fi 6E provides up to 1200MHz in the 6GHz band for higher throughput and improved application performance. With up to seven 160MHz channels, Wi-Fi 6E can better support lowlatency, bandwidth hungry applications like high-definition video and artificial reality/virtual reality applications. Only Wi-Fi 6E capable devices can use the 6GHz band so there is no interference or slowdowns due to legacy devices.

Device class support

For operation in the 6GHz band, the 650 Series APs are part of the low power indoor (LPI) device class. This fixed indooronly class uses lower power levels and does not require an Automated Frequency Coordination service (AFC) to manage incumbent outdoor services which is required for standard class APs. ARUBA 650 SERIES WI-FI 6E CAMPUS ACCESS POINTS Flagship offering with the performance to meet growing enterprise needs with Wi-Fi 6E


650 Series Access Points include Aruba’s ultra tri-band filtering, which enables enterprises to take advantage of the entire 5GHz and 6GHz bands without experiencing interference, while operating on any channel in either band concurrently. Since there is only 50MHz between 5GHz and the 6GHz, without advanced filtering, enterprises would likely experience problems between the bands and would therefore be limited in the number of channels available. By applying advanced filtering capabilities, enterprises can take full use of available spectrum without creating coverage gaps or islands.


The Series 650 APs provide high availability with two HPE Smart Rate ethernet ports for hitless failover for both data and power. Configurable to 1, 2.5, or 5 Gbps, these dual ports provide business continuity for mission critical applications.


While the need for more Wi-Fi capacity is recognized across the globe, countries are approaching 6GHz differently. The 650 Series APs are set up to automatically update regulatory rules once 6E regulations have been approved and certified.


The 650 Series APs are based on the 802.11ax standard, which means that all its efficiency and security enhancements are also available on the 6GHz band. Wi?Fi 6 features such as Orthogonal Frequency Division Multiple Access (OFDMA), BSS coloring, Enhanced Open, and WPA3 are fully supported on the Aruba Wi-Fi 6E access points as well.

Advantages of OFDMA

This capability allows Aruba’s APs to handle multiple 802.11ax capable clients on each channel simultaneously, regardless of device or traffic type. Channel utilization is optimized by handling each transaction via smaller sub-carriers or resource units (RUs), which means that clients are sharing a channel and not competing for airtime and bandwidth. The 650 Series APs supports up to 37 resource units, the maximum as defined in the standard for an 80MHz channel.

Advantages of MU-MIMO

MU-MIMO can be used to increase the capacity and aggregate performance by relying on spatial multiplexing to communicate with up to four client devices simultaneously. The 650 Series APs supports 4x4 MU-MIMO in both uplink and downlink directions.


Client optimization

Aruba’s patented AI-powered ClientMatch technology eliminates sticky client issues by steering a client to the AP where it receives the best radio signal. Client Match steers traffic from the noisy 2.4GHz band to the preferred 5GHz or 6GHz band depending on client capabilities. ClientMatch also dynamically steers traffic to load balance APs to improve the user experience.

Automated Wi-Fi radio frequency management

To optimize the user experience and provide greater stability, Aruba AirMatch allows organization to automate network optimization using machine learning. AirMatch provides dynamic bandwidth adjustments to support changing device density, enhanced roaming using an even distribution of Effective Isotropic Radiated Power (EIRP) to radios, and real-time channel assignments to mitigate co-channel interference.

Application Assurance

With Air Slice, organizations can provide application assurance to their users that goes beyond the traditional capabilities of airtime fairness. After the SLAs are configured, Air Slice monitors network usage, automatically allocates radio resources, and dynamically adjusts radio resources as new users connect and applications sessions begin or end.

Aruba Advanced Cellular Coexistence (ACC)

Unique to Aruba, Advanced Cellular Coexistence uses built-in filtering to automatically minimize the impact of interference from cellular networks, distributed antenna systems (DAS), and commercial small cell or femtocell equipment.

Intelligent Power Monitoring (IPM)

For better insights into energy consumption, Aruba APs continuously monitor and report hardware energy usage. Unlike other vendor’s access points, Aruba APs can also be configured to enable or disable capabilities based on available PoE power – ideal when wired switches have exhausted their power budget. Enterprises can deploy Wi-Fi 6E APs and update switching and power at a later if needed based on their actual usage. Other power options include adding a power injector or using Smart PoE to combine power from two cables.


Indoor location shouldn’t require guesswork or costly overlay technologies. Aruba’s Wi-Fi 6 and 6E APs help organizations leverage their wireless investment to deliver indoor location – everywhere. The 650 Series Campus APs include built-in GPS receivers and intelligent software to allow them automatically locate themselves accurately within the universal framework of latitude and longitude. As part of Aruba’s indoor location solution, they serve as reference points for client devices using fine time measurements and other location technologies.

Aruba’s Wi-Fi 6 and 6E APs support Open Locate, an emerging standard that allows APs to share their location over the air and through cloud-based APIs, enabling mobile devices to locate themselves and applications to support network analytics.


The 650 Series includes an integrated Bluetooth 5 and 802.15.4 radio for Zigbee support to simplify deploying and managing IoT-based location services, asset tracking services, security solutions, and IoT sensors. There is also a USBport extension to provide IoT connectivity to a wider range of devices. These IoT capabilities allows organizations to leverage the Aruba APs as an IoT platform, which eliminates the need for an overlay infrastructure and additional IT resources and can accelerate IoT initiatives.

In addition, Target Wake Time (TWT) establishes a schedule for when clients need to communicate with an AP. This helps improve client power savings and reduces airtime contention with other clients, which is ideal for IoT.


The Aruba 650 Series includes build-security capabilities such as:

WPA3 and Enhanced Open

Support for stronger encryption and authentication is provided via the latest version of WPA for enterprise protected networks. Enhanced Open offers seamless new protection for users connecting to open networks where each session is automatically encrypted to protect user passwords and data on guest networks.


MPSK enables simpler passkey management for WPA2 devices – should the Wi-Fi password on one device or device type change, no additional changes are needed for other devices. This capability requires ClearPass Policy Manager.


To improve security and ease of management, IT can centrally configure and automatically enforce role-based policies that define proper access privileges for employees, guests, contractors, and other user groups – no matter where users connect on wired and WLANs. Dynamic Segmentation eliminates the time consuming and error-prone task of managing complex and static VLANs, ACLs, and subnets by dynamically assigning policies and keeping traffic secure and separated.


Built on the technical foundations of Passpoint® and Wi-Fi Calling, Air Pass creates a roaming network across the Aruba enterprise customer footprint, extending cellular coverage and enhancing the visitor and subscriber experience to deliver a great experience for your guests while reducing costs and management overhead for DAS.


Our unified APs can operate as standalone access points or with a gateway for greater scalability, security, and manageability. APs can be deployed using zero touch provisioning – without on-site technical expertise – for ease of implementation in branch offices and for remote work. Aruba APs can be managed using cloud-based or onpremises solutions for any campus, branch, or remote work environment. As the management and orchestration console for Aruba ESP (Edge Services Platform), Aruba Central provides a single pane of glass for overseeing every aspect of wired and wireless LANs, WANs, and VPNs. AI-powered analytics, end-to-end orchestration and automation, and advanced security features are built natively into the solution.


Aruba 650 Series Access Points are designed to take advantage of the 6GHz band using three 4x4 MIMO radios for comprehensive tri-band coverage to meet the growing demands of Wi-Fi due to increased use of video, growth in client and IoT devices, and expanded use of cloud. With a maximum combined 7.8 Gbps data rate for higher throughput and faster speeds for indoor use, the 650 Series raises the bar in terms of capacity, wider channels, hitless failover, and less interference between the 5GHz and 6GHz bands.
