title: Telemedicine systems and telecommunications.
abstract: Successful telemedicine requires appropriate equipment and some kind of telecommunications medium. However, successful telemedicine requires more than just technology. The three essential components are the personnel, the technology and a liberal measure of perseverance. Before the technology can be selected, it is necessary to consider the nature of the information to be transmitted between the sites and the time frame over which it must be sent to achieve the desired clinical goals, because this will determine the choice of equipment and the telecommunications network. Factors to be considered include the types of information to be transmitted, the quantity of information to be transferred, and security and privacy (e.g. in Europe and the USA there has been recent legislation about data security). The choice of transmission method for any telemedicine application is, in practice, a compromise between what one would like and what one can afford. In practice, various trade-offs have to be made, which include cost, availability of the service (i.e. the coverage), bandwidth, reliability and quality of service. Equipment and the telecommunications medium are a necessary, but not sufficient, pre-requisite for a successful telemedicine programme. The right people are also required and they must be properly trained.
