Abstract: A system and method provide for establishment and use of permission sets for subscribers where client applications in a wireless communication environment are requesting location information for a particular wireless communications device from a provider of such information. The system described herein provides the capability for a wireless communications device operator to establish a profile wherein limitations may be placed on the provision of such location information based on such things as the requesting party, spatial and temporal limitations, as well as granularity. The system described herein may be further configured such that an authentication process is preformed for client application seeking location information which would require the registration of such client applications with a centralized processing system.

Abstract: Enhancements to the base station of an infrared-linked communication system include tubular reflective concentrator apparatus for reflecting IR signals entering an inlet end onto a photodetector located at an outlet end. Signal-to-noise ratio is improved, signal gain in attained, and unwanted light signals are excluded thereby. The tubular reflective concentrator apparatus can also be employed with IR emitters to focus and direct emitted light from an LED or the like towards a predefined field of view. Multiple tubular reflective concentrator apparatus is shown implemented in a unitary, molded plastic shell. The photodetectors and emitters can also be mounted at the bottom of an associated tubular reflective concentrator apparatus with a plug attached thereto so that they can be plugged into a support structure to provide custom installations where necessary.
