WLAN 802.11a/b/g/j/p/n/ac/af/ah/ax

Take WLAN technology ideas from concept to consumer with confidence. Keysight keeps pace with the constantly evolving WLAN standards - including 802.11ax, 802.11ac, and 802.11ad – all with a clear goal to continuously improve spectrum utilization, throughput and user experience. The Keysight solutions on this page support a wide range of WLAN technologies from legacy 802.11 a/b/g/n to vehicular communication 802.11p and to the latest 802.11ac and 802.11ax standards. For next generation WLAN technologies in the mm-Wave band, visit our 802.11ad/ay solutions page.

802.11ax is the next-generation WLAN standard with a promise to add significantly higher efficiency, capacity and coverage for a better user experience, especially for dense deployment scenarios in both indoor and outdoor environments. 802.11ax, also known as High Efficiency (HE) WLAN, builds upon 802.11ac. However, unlike 802.11ac, it operates in both 2.4- and 5-GHz bands and employs advanced technology building blocks such as OFDMA for high efficiency, 8x8 MU-MIMO for high capacity in both uplink and downlink directions, and uplink scheduling for increased capacity, efficiency and better user experience. Other technologies, such as 1024-QAM modulation, are used to improve throughput.

802.11ac, the Very High Throughput (VHT) amendment to the 802.11 standard, is now a mainstream WLAN technology. It operates in the 5-GHz band and extends the limits of 802.11n with new and enhanced technologies, including wider channel bandwidth of up to 160 MHz, up to eight spatial streams, new 4x4 MU-MIMO technology in the downlink direction, and 256-QAM modulation.

802.11p is an approved amendment to 802.11-2012 that adds the vehicular communication system known as Wireless Access in Vehicular Environments (WAVE). The standard defines enhancements to 802.11 to support Intelligent Transportation System (ITS) applications. This includes data exchange between high-speed vehicles and between the vehicles and the roadside infrastructure in the licensed ITS band of 5.9 GHz (5.85-5.925 GHz).
