1. A network comprising:
- a network backbone capable of two-way communications;
a plurality of radio transceivers attached to said network backbone that;
have overlapping coverage areas;
establish communications with a first mobile device;
determine that said first mobile device is communicating with a first of said plurality of radio transceivers;
simultaneously transmit a first communication to said mobile device from a first set of said plurality of radio transceivers, said first set of said plurality of radio transceivers comprising at least two of said plurality of radio transceivers;
receive a second communication from said mobile device by one or more of said first set of radio transceivers; and
a network controller adapting to determine a movement vector for the said first mobile device.

Abstract
In a network having multiple wireless transmitters, a mobile device operating with the network may be assigned one or more wireless transmitters as a virtual cell. Transmissions to the mobile device may be broadcast from several cells simultaneously, so that the mobile device will receive the transmissions in any of the areas covered by the cells. When the network determines that the mobile device is moving out of one cell area and into another, the virtual cell may move as well. The virtual cell may consist of one or many areas covered by a wireless network, and may have a shape that is determined by geography, trajectory, wireless coverage, or other factors.
