This feasibility study evaluated the viability of data transmissions over the GSM voice channel in comparison with the GSM CSD channel. After a brief technology analysis, the fundamental limits which apply to both transmission modes were discussed. A critical review of existing solutions and approaches, including related patents and products, have been given. Finally, several possible solutions with different grades of implementation complexity are outlined. The study closes with recommendations about the preferred technical solution.
