Low-rate data over GSM voice channel
This project involved working with a start-up company developing technology to
transmit low-rate data over the GSM voice channel.
The initial prototype successfully enabled proof-of-concept demonstrations
and gave a platform for the software development. The design involved
the integration of DSP, RISC processor, RAM and DATAFLASH memory and FPGA.
The second prototype incorporated a GSM module, battery charging and power
management and was ready for investor demonstrations in time.
