System and method to pack cellular systems and WiFi within a TV channel
First Claim
1. A G-WiFi system comprising a G-WiFi base station or Access point and G-WiFi terminals;
- G-WiFi base station comprising a GSM transceiver unit, G-WiFi transceiver unit of 5 MHz spectrum and they share a TV spectrum;
G-WiFi terminal comprising a GSM transceiver and a WiFi transceiver or other transceivers using TV spectrum;
GSM and WiFi has a master-slave relationship and GSM base station or access point broadcasts G-WiFi system information (GSI) regularly and WiFi system is controlled by GSM system to turn on/off;
WiFi system will calibrate and synchronize its timing with GSM timing.

Abstract
An inventive system allows GSM as a master signaling and timing system to operate WiFi within a TV channel. GSM system will broadcast system information regularly and GSM unit of the terminal will regularly wake up to check those system information and wakeup messages to keep being associated with G-WiFi base station. WiFi units of the G-WiFi system will be dormant and become active when triggered by GSM counterparts. There is provided a method to partition the TV channel among GSM or CDMA or TD-SCDMA or 1xEVDO and WiFi system. GSM frequencies for uplink and downlink may not have a deterministic relationship and may be assigned dynamically. This method can be applied to other frequency band to allow GSM, WiFi, TD-SCDMA, CDMA, WCDMA etc to share an available spectrum such as the current GSM spectrum, TD-SCDMA spectrum etc.
