W telefonach innych niż flagowce (a i tam często tak jest) najczęściej stosuje się moduł wifi który jest 1x1.   (You need to Login or Register ktoś fajnie to objaśnił:

1x1 and 2x2 refer to the number of transmit and receive radio chains built into the Wi-Fi card. 2x2 means it has two transmit and two receive radio chains, and usually implies that it supports 2 "spacial streams", which is a key way that 802.11n is faster than the previous generation of Wi-Fi technologies. 802.11n is the first standard in the 802.11 family to support MIMO (pronounced "MY-moh"), which stands for "Multiple Inputs, Multiple Outputs", which is basically a way of ganging together multiple radios to get faster data rates than you can get with a single radio on each end of the connection. Because it's possible to create a wireless card with 2 transmit and 2 receive radio chains but still not do real 2 spacial stream MIMO, some people in the industry now use the notation TxR:S, where T is the number of Transmit radio chains, R is the number of Receive radio chains, and S is the number of supported "spacial streams".
