1. A communications system for secure wireless communications, said communications system comprising:
- a first device having transceiving means therein for communicating in a first and a second communication mode;
a second device, in wireless communication with said first device, said first and second devices wirelessly communicating in said first communication mode using an infrared signal and in said second communication mode using a radiofrequency signal;
wherein said first and second devices transceive a plurality of messages therebetween in said second communication mode;
wherein, prior to transceiving a security message therebetween, said first and second devices switch transceiving to said first communication mode, and transmit said security message in said first communication mode;
wherein, upon said second device switching said transceiving to said first communication mode, said second device transmits an infrared request message to said first device.

Abstract
A system, method and apparatus for establishing a secure wireless radio communications link between two devices that minimizes the exposure of sensitive information to third party interception is disclosed. The secure link is established by first establishing an infrared link between the two devices for the exchange of sensitive information, such as encryption information. Subsequent communications would then have the benefit of encryption protection, establishing the secure wireless radio communications link.

14. A transceiving device for secure wireless communications in a communications system, said device comprising:
-
radiofrequency transceiving means for transceiving a plurality of radiofrequency transmissions within said communications system; and
infrared transceiving means for transceiving a plurality of infrared transmissions within said communications system;
wherein said transceiving device switches transceiving from said radiofrequency transceiving means to said infrared transceiving means prior to the transmission of an infrared security message within said communications system; and
wherein, upon said transceiving device switching transceiving to said infrared transceiving means, said transceiving device transmits an infrared request message to a second transceiving device. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
