What is WLAN?

WLAN Explained

WLAN ensures that your devices can connect to the network or internet no matter where you are located. Instead of using cables to connect to the internet, devices use radio wireless connections (Wi-Fi). Because Wi-Fi signals are transmitted through the air, securing your wireless network is critical.

Aruba enterprise WLAN provides

  • High-performance, secure enterprise wireless LAN with Wi-Fi 6 certification and interoperability with previous generations of Wi-Fi standards
  • Support for Wi-Fi 6E, which extends Wi-Fi 6 to the 6 GHz band to provide more contiguous spectrum and less interference
  • Support for greater mobility, IoT, and digital transformation initiatives – and rising user expectations
  • Patented RF optimization and AI-powered automation to improve user experience and operator efficiency
  • Built-in security with dynamic segmentation to ensure secure guest access, IoT device connectivity, and protect your Wi-Fi network from threats


  • Growth in mobility and IoT: According to IDC, IoT is forecast to growth to 41.6bn devices by 2025, generating 79.4 zettabytes of data. Mobility, roaming, cloud, cellular offload, device onboarding, and security issues mean that Wi-Fi needs to support convergence, higher throughput, and more efficient RF utilization.
  • Growth in diversity of applications: Latency sensitive video applications are on the rise with 45%/year growth through 2023. UCC spending is growing to $44.2B by 2021.
  • Growth in user expectations: Low tolerance for poor network performance leads to executive pressure. The network and applications must be reliable, secure, and always on.

To accelerate digital transformation and future-proof for IoT, Aruba WLAN provides edge connectivity that’s intelligent, safe, and fast. With AI-powered mobility and enterprise-class design, Aruba APs deliver superior services and segmentation without the complexity that other vendors add. Based on Wi-Fi 6 standards, Aruba delivers critical security and reliability to mobile users, IoT, and latency-sensitive apps to better support hybrid workplaces.

WLAN Use Cases

Use CaseProblemSolution

Application assurance

As voice and video consume greater amounts of bandwidth, users may suffer from poor quality of service

Optimize radio resources with Wi-Fi 6 capabilities (OFDMA and MU-MIMO) and Aruba Air Slice (which optimizes user experience and assures QoA to enterprise applications).


Wi-Fi calling

Inconsistent indoor cellular coverage

Seamlessly connect to Passpoint-enabled wireless network using Aruba Air Pass for cellular handoffs.

IoT connectivity

IoT requires an additional overlay gateway or server

Use existing AP infrastructure to provide IoT connectivity at the Edge with support for Bluetooth Low Energy (BLE), 802.15.4/Zigbee, or USB-port extensions.

Secure guest access

Guest traffic is passed unencrypted

Leverage built-in Wi-Fi 6 encryption such as Enhanced Open plus a network access control solution, such as Aruba ClearPass.

Digital transformation

WLAN connectivity is slow or unreliable

Use AIOps for closed loop recommendations and peer benchmarking to ensure the success of digital transformation initiatives.
