Wireless universal personal access system

摘要

The invention relates to a two-way bi-directional wireless-based access communication system that allows a user to access any one of multiple independent secured domain systems from a single handheld remote keyless entry device, whereupon activation of the remote keyless device by the user, an encoded request signal containing a predetermined access code is generated and transmitted by the remote keyless entry device to one of the multiple secure domain systems. And, based on the access code contained within the encoded request signal, the domain system determines the validity of the access code and transmits a corresponding encoded authorization signal to user at the transceiver device.
