Abstract
The performance of mobile telemedical communications links based on the IS 54 and GSM cellular telephone standards the most widely used commercial systems in North America and Europe respectively was studied by computer simulations A photoplethysmography signal was used to investigate the transmission of medical data over simulated mobile phone channels Various conditions were simulated in the communications path between a mobile transmitter and receiver from perfect to distorted conditions The results showed successful transmission with bit error rates of better than 10 7 at the receiver for the IS 54 standard The performance of the IS 54 standard was superior to that of GSM in terms of minimum path delay variations especially in built up urban areas
