FURTHER RESULTS: The receiving end applications display the medical information (e.g. ECG trace, pulse, blood pressure, oxygen saturation levels), image, GPS position and text messages on a PC monitor. A PC dispatcher application is available for sending and receiving SDS and status messages. In addition, a mapping application was provided for displaying the location updates. Another major achievement in this project was the deployment of an advanced multiplexing technology. It is used in the Tele-Medic system which allows the simultaneous transmission of different types of data involved. This multiplexing technology gives priority to time critical data such as ECG data, which requires accurate timing of transmission for proper operation.
