WLAN 802.11ax test and measurement equipment vendors
This page describes WLAN 802.11ax test and measurement equipment vendors with their features. It mentions features of 802.11ax equipments used for test and measurement of transmitter and receiver specifications of 11ax compliant device.
What is WLAN 802.11ax ?
Introduction:
IEEE has recently published draft version of 802.11ax standard known as wifi-6.
The standard is going to be ratified in 2019.
It is successor to 802.11ac but operates in both 2.4 GHz and 5 GHz bands.
There are many new features added in newly released standard such as
OFDMA in both downlink and uplink, MU-MIMO with beamforming in the downlink,
MU-MIMO in the uplink, 1024-QAM, increased guard and symbol duration,
larger bandwith (upto 160 MHz), BSS color, special packet format for outdoor applications and so on.
Refer WLAN 802.11ax tutorial >>.
The WLAN 802.11ax device consists of transmitter and receiver parts which are required to be validated by test and measurement equipments. Hence these equipments are designed taking into considerations specifications of 11ax DUT (i.e. AP or STA). Refer 802.11ax testing >> which mentions 802.11ax transmitter and receiver test specifications. Figure depicts test setup used to test transmitter part of 11ax station (i.e. client).
