1. A system for obtaining sensor information to locate a plurality of portable devices, said system comprising:
- a first controller device operable to communicate with a first portable device via a first communication channel of a first communication link, wherein the plurality of portable devices includes the first portable device;
a second controller device operable to communicate with a second portable device via a second communication channel over a second communication link, wherein the plurality of portable devices includes the second portable device;
a communication supervisor configured to direct the first controller device and the second controller device to communicate via the first communication link and the second communication link such that simultaneous communications over the first communication link and the second communication link occur over at least one of different channels and different times; and
a plurality of sensor devices, each sensor device of the plurality of sensor devices configured to obtain a sensed characteristic with respect to communications of the first communication link and the second communication link.

Abstract
A system and method to determine location information with respect to a plurality of portable devices, with potentially a large number of portable devices such as 40 or more portable devices in proximity to the system. The system may connect to and locate each of the plurality of portable devices in proximity to the system. The location information may be determined with respect to an object, such as a vehicle or building, and optionally within a larger system of objects, such as a mass transit system.

24. A method of determining a location with respect to a plurality of portable devices, said method comprising:
-
communicating, between a first controller device and a first portable device, via a first communication channel of a first communication link, wherein the plurality of portable devices includes the first portable device; communicating, between a second controller device and a second portable device, via a second communication channel of a second communication link, wherein the plurality of portable devices includes the second portable device; directing a plurality of sensor devices to obtain a sensed characteristic of communications on the first communication link and the second communication link; determining a first location of the first portable device based on the sensed characteristic of communications obtained with respect to the first communication link; and determining a second location of the second portable device based on the sensed characteristic of communications obtained with respect to the second communication link. - View Dependent Claims (25, 26, 27, 28)
