Next Generation Wireless LAN Technology


The IEEE 802.11 Wireless LAN WG (Working Group) develops and maintains a set of media access control (MAC) and physical layer (PHY) specifications such as 11n, 11ac, and 11ax for wireless local area network (WLAN) communication in unlicensed frequency bands.

The Wi-Fi Alliance (WFA) certifies Wi-Fi products for interoperability conformity to IEEE/WFA standards under various certification programs such as Wi-Fi Display and Wi-Fi EasyMesh.

WILUS has actively participated in the standardization of IEEE 802.11ax HEW (High Efficiency WLAN), which will be the 6th generation wireless LAN standard. Based on our experience in IEEE and 3GPP standardization activities, we proposed many technologies enabling the enhanced Wi-Fi experiences. We also have participated in IEEE 802.11ba WUR (Wake Up Radio) specification, which solves the conflicting goals of low power consumption and low latency to increase the battery life of WLAN based IoT devices. We are also contributing to IEEE 802.11be EHT (Extremely High Throughput). It will enable new high-throughput, low latency applications such as 4K/8K video streaming, virtual reality or augmented reality, gaming, remote office and cloud computing.


The IEEE 802.11be is a newly created task group defining the next generation of Wi-Fi, following the 802.11ax. The objective is to increase the peak throughput of at least 30Gbps in the 2.4, 5 and emerging 6 GHz bands. It will enable new high-throughput, low latency applications such as 4K/8K video streaming, virtual reality or augmented reality, gaming, remote office and cloud computing.

WILUS is actively participating in 11be from its study group phase in areas such as requirements of low latency networking from virtual reality streaming and coordinated transmission from multiple access points.

  • Extremely high throughput of at least 30Gbps from 16 spatial streams and 320MHz bandwidth
  • Low latency from multi-link/band aggregation and MAC enhancements
  • Enhanced link adaptation and retransmission protocol

Multi-link Aggregation

Aggregation of multiple RF links for increased overall performances

Multi-AP Coordination

Coordinated transmission of interference nulling from multiple APs

Hybrid ARQ

Reliable throughput under degraded channel quality


The IEEE 802.11ax standard is the latest technology replacing the current 802.11ac WLAN devices, providing scalability and un-compromised performances. It lets access points support more clients in dense environments and provide a better experience for typical wireless LAN networks. It provides up to 4x increase in capacity with power consumption reduced by up to 2/3.

WILUS has been actively contributing to 11ax from its first task group meetings in areas such as spatial reuse, OFDMA signaling, and multi-user MAC enhancements.

  • Enhanced scalability from OFDMA in dense WLAN environment
  • Increased maximum speed up to 10Gbps from 1024-QAM and MIMO
  • Reduced power consumption with flexible wake-up time scheduling
  • Support outdoor operations
  • Spatial reuse increases network capacity by allowing more simultaneous transmissions

Spatial Reuse

Simultaneous transmissions in neighbor networks


The IEEE 802.11ba working group offers a solution to the challenge of prolonging the life cycle of IoT devices operating in batteries. IoT devices should minimize power consumption while being responsive to external queries which means that devices must be able to run in a low-power, low-latency state. The Wake-Up Receiver is a low-power companion receiver supporting low-latency wake up of the main WLAN chipset.

WILUS has been actively contributing to 11ba in areas such as frame format, wake up operation, and alignment with the previous 802.11 power save mechanisms.

  • Provides maximum lifetime for WLAN-based IoT devices
  • Coexistence with legacy WLAN devices
  • Essential for manufacturers and users of sensors and devices for the Internet of Things
