Assume a MU-MIMO capable wifi access point with two external antennas. The antennas are placed in two different locations. It's not possible for a wifi signal to reach (via air) from one location to the other.

Given this setting: Should the access point be able to serve clients at both locations simultaneously? (E.g one client at one location, one client at the other)

Put differently: Do clients need to be able to receive from both antennas of that access point in order to establish a connection?

    Antennas for MU-MIMO need to be in relative proximity - how is the beam shaping supposed to work otherwise? – Zac67 Aug 12 '19 at 14:18
  • @Zac67 .. do you have a source for this? If only one antenna carries the signal for a client then that forms a "beam" (localized signal), too, doesn't it? – Daniel Jour Aug 14 '19 at 10:27
  • No. (Virtual) beam forming implies the presence of an antenna array (2+). The beam is formed by multiple, spatially distinct, interfering signals. With a single antenna the antenna shape would need to be exactly as required - that can't be done ad-hoc. en.wikipedia.org/wiki/Beamforming – Zac67 Aug 14 '19 at 12:37
