Abstract
A device includes a first wireless transceiver initiating a communication session; and a second wireless transceiver. The device shifts the communication session to the second wireless transceiver if a signal strength of the first wireless transceiver is below a predetermined level and the signal strength is not expected to increase above the predetermined level.
Claims22
A method, comprising:
- communicating via a first communication protocol;
- determining, if a signal strength is below a predetermined signal threshold, a probability that the signal strength is expected to increase above the predetermined signal threshold;
- and
- shifting communications to a second communication protocol, if the probability is below a predetermined probability threshold.

A device, comprising:
- a first wireless transceiver initiating a communication session;
- and
- a second wireless transceiver, the device shifting the communication session to the second wireless transceiver if a signal strength of the first wireless transceiver is below a predetermined level and the signal strength is not expected to increase above the predetermined level.
A system, comprising:
- a plurality of access points having a coverage area;
- a mobile device conducting a communication session via at least one of the plurality of access points;
- and
- a wireless switch coordinating the access points,
- wherein a position of the mobile device is monitored to determine whether the device is expected to exit the coverage area, and wherein the communication session is shifted to a network not including the access points if the mobile device is expected to exit the coverage area.
