WIRELESS SYSTEM SYNCHRONIZATION USING FREQUENCY SHIFT MODULATION AND ON-OFF KEYING MODULATION

摘要

A system and method of wireless communication, in which both OOK and FSK modulation transceivers are used for communication among participating devices. On-Off Key (“OOK”) may be used to awaken a communication device, establish a communication channel, and handle transmission and reception of the control signal. In doing so, communication devices operating according to the invention may use less power than conventional communication devices. Once certain initial data is exchanged between communication devices, Frequency Shift Keying (“FSK”) may be used to provide the ability for many users to communicate in a more secure fashion, so that sensitive information, such as voice and data, may be transmitted between communication devices. In this manner, the privacy of data and voice signals may be more securely protected and transmitted by the FSK modulated signal.
