WiFi-Based Telemedicine System: Signal Accuracy and Security

Accuracy and security of medical information, when a patient vital sign signal such as respiratory sounds must be transmitted through a communication channel, are two essential important features in design of telemedicine systems and in medical diagnosis. This paper studies medical signal accuracy in WiFi-based telemedicine system. When system resources are limited such as the transmission bandwidth of a WiFi channel, appropriate utility of available resources to enhance information accuracy becomes imperative. This paper also studies security issue for WiFi-based telemedicine system. When a WiFi channel is selected to transmit or receive medical signals, carefully choose and design security features and methods such as authentication and encryption are crucial.
