MIMO makes use of the advantages of having several ... For Wi-Fi, the modulation is orthogonal frequency division multiplexing (OFDM) using binary phase-shift keying (BPSK), quadrature phase ...

Both MU-MIMO and OFDMA are multiuser technologies that ... to single-user Orthogonal Frequency Division Multiplexing (OFDM) because the speed of transmit links remains unchanged.

802.11ax brings MIMO with orthogonal frequency-division multiplexing (OFDM) to the table. What that means is 802.11ax routers can broadcast four MIMO spatial streams, giving you four times the maximum ...

MIMO is the use of multiple antennas at both ... 802.11ac specifies a modulation scheme of up to 256QAM for the OFDM mode. 256QAM modulation is four times denser than 64QAM, which was the highest ...

Either way, OFDM, OFDA, and OFDMA refer to methods of ... Multiply that out to a 4x4 MIMO network and you get a total capacity of 14Gbps. If you had a smartphone or laptop capable of two or ...

How does NHK transmit 500Mbps over a few miles, then? Using OFDM (orthogonal frequency-division multiplexing), MIMO (multiple-input, multiple-output, i.e. using more than one antenna), and two ...

Huawei said the two companies are continuing to test Massive MIMO; mixed numerology using filtered OFDM (f-OFDM); and combined performance of Sparse Code Multiple Access (SCMA), Polar Code ...
