Abstract

Abstract A cellular telephone communication protocol enables a communication link primarily for the transmission of voice and data. At predetermined intervals or on-demand data regarding location, an event, or a condition is sent by muting the voice audio and sending a data frame having a pre-determined sequence. Following the transmission of the location, event, or condition data transmission of voice and data is resumed. The communication link uses a half duplex, frequency shift, keying modulation technique.
