Solved: 2x2 mimo vs 3x3 mimo - Airheads Community Community. Students working with me have tested 2x2, 3x3, 4x2 and 4x4 MIMO with discrete rubber duck, helix, and patch antennas. The downside of 4x4 is potentially cost, a small degree of added complexity, possibly power consumption and circuit board real estate, and, most notably at present, availability. This will make it possible to use wireless docking, storage, networking, displays and other devices simultaneously while localizing traffic and offloading the longer range AC and N communications on 2. It works in 5 GHz only. e. I understand theoretically the difference between 4X4 and 2X2 Mimo, however I'm wondering if anyone has any real world experience between the two? Can we expect to see For 2x2, the speed becomes two times faster than the SISO LTE and for 4x4 the speed becomes four times faster than the SISO LTE at maximum. 11ac will change this a bit in the future. Range is purely a function of transmission power and antenna efficiency it has nothing to do with mimo. 3x3 MIMO at difficult-to-reach locations. 4 GHz or 5 GHz radio waves per IEEE 802.

Is 4x4:3 MIMO in 3700AP better than 3x3:3 in 2700 for Wall Penetration Hi I wanted to know whether it really matters, the 3700AP vs the new 2700AP for environments like ours where the APs encounter concrete walls and the signal strength drops. The fun can begin earlier than if the pool was being filled by only three hoses. I have factory reset the router multiple times. These numbers refer to the number of antennas and the number of streams they can use to communicate with the WiFi router. 73 Gbps maximum link rates. 11 family (which is marketed under the brand name Wi-Fi), developed in the IEEE Standards Association, providing high-throughput wireless local area networks (WLANs) on the 5 GHz band
