System and method for managing handoff of a client between different distributed-input-distributed-output (DIDO) networks based on detected velocity of the client
First Claim
1. A machine-implemented method within a plurality of multiuser (MU) multiple antenna system (MU-MAS) networks, each with different network characteristics relative to a user device velocity, for adjusting communication between a plurality of distributed antennas or wireless transceiver devices distributed throughout a cell or coverage area and a plurality of client devices, the method comprising:
- sending radio frequency (RF) energy between the plurality of distributed antennas and the plurality of client devices;
creating a plurality of simultaneous non-interfering data streams within the same frequency band between the distributed antennas and the client devices via precoding;
estimating a current velocity of a first client device of the plurality of client devices; and
assigning the first client device to a first network of the plurality of MU-MAS networks having first network characteristics based on the estimated velocity of the first client device, the plurality of MU-MAS networks including at least a second network having second network characteristics.

Abstract
A system and method are described for adjusting communication with a first distributed-input-distributed-output (DIDO) client. For example, a method according to one embodiment comprises: sending RF energy to the DIDO client from one or more antennas of a DIDO network; estimating a current velocity of the DIDO client; and assigning the client to a particular DIDO network based on the estimated velocity of the client.
