MU-MIMO al­lows a router to trans­mit sep­a­rate sig­nals to mul­ti­ple de­vices si­mul­ta­ne­ously

Beam­form­ing

Older routers used to trans­mit data in all di­rec­tions in the hope that the sig­nal would reach any de­vices within range. The lat­est 802.11ac routers use beam­form­ing to aim it at in­di­vid­ual de­vices more ac­cu­rately.

1 In­side , Out­side

Routers with 802.11ac use mul­ti­ple an­ten­nas to boost sig­nal strength. Net­gear’s R7800 has four large an­ten­nas on the out­side, but ri­vals such as the BT Smart Hub hide them neatly in­side.

2 In­ter­net Ac­c­cess

Re­mem­ber that a router such as the R7800 can con­nect your de­vices to­gether, but it doesn’t in­clude a mo­dem for con­nect­ing to the in­ter­net. You’ll need a sep­a­rate mo­dem or a com­bined mo­dem-router for in­ter­net ac­cess.
