with the first standard to specify MIMO and to use both 2.4 and 5GHz bands

Wi-Fi 4 connects reliably based on the same protocol features on both 2.4Ghz and 5Ghz bands. It is the first protocol to utilize more than one antenna to maximize thoughput and range. Originally introduced in 2007 as 802.11n to be later assigned the Wi-Fi4 label.
Wi-Fi4 comes with a host of additional features, like standardized support for multiple-input multiple-output (MIMO), 40 MHz channels to the PHY (physical layer) and frame aggregation to the MAC layer, security improvements, the use of MIMO-OFDM, modulation at 64-QAM rate, and more.

Heroic milestone & legacy support.

802.11n a.k.a. Wi-Fi4 changed the way we thought about connectivity, making wireless a highly desirable feature across device and application. The update bought in cumulative improvements like the 40Mhz channels, security.features, multiple antenna chains and MIMO.

Wi-Fi 4 multiplied and affirmed the use of 802.11 in our everyday life.


Electromagnetic Certification strategies can be complex even with plateaued and legacy technologies. Extended support, maximization of life-cycle and frictionless obsolesce planning are key trust and relationship matters related to solid compliance management.
