Transtelephonic electrocardiographic transmission (TET) is the most widespread form of telecardiology since it enables clinicians to assess patients at a distance. The purpose of this study was to assess the efficacy and effectiveness of TET either by fixed telephone line (POTS) or by mobile phone in the preparticipation screening of young athletes. A total of 506 players, aged 20.5 6.2 years, from 23 soccer clubs in the prefecture of Thessaloniki, Greece, were physically examined in their playfields by a general practitioner (GP) and had their ECG recorded. In 142 cases, and on the judgment of the GP, the ECG was transmitted via POTS and/or global system for mobile communications (GSM) to a specialised medical centre where it was evaluated by a cardiologist. The mean total time for recording, storing, and transmitting the ECG was four minutes per subject. It was found that the success rate for transmission at first attempt was similar for both fixed and mobile networks, that is, 93% and 91%, respectively. The failure rate in the GSM network was correlated to the reception level at the site of transmission. Only in about half ( = 74) of the transmitted ECGs did the cardiologist confirm “abnormal” findings, although in 16, they were considered to be clinically insignificant. Consequently, 58 athletes were referred for further medical examination. Our results indicate that TET (either by fixed telephone line or by mobile phone) can ensure valid, reliable, and objective measurements, and significantly contribute to the application of medical screening in a great number of athletes. Therefore, it is recommended as an alternative diagnostic tool for the preparticipation screening of athletes living in remote areas.

This streetlight monitoring system is aimed at preventing unnecessary energy wastage by applying the GSM (Global System for Mobile Communications) technology. This system consists of two parts: the monitoring centre and the terminal nodes. The Siemens TC35 GSM module is used to send and receive short messages and it is installed in the monitoring centre and each streetlight. ATmega168 is used to determine whether or not it is necessary for the streetlights to be turned on, and then it executes commands from the control centre. When the sky is bright enough for drivers, the streetlights will automatically turn off. Also, if some streetlights are broken down, the TC35 GSM module will send an alarm short message to the monitoring centre and maintenance personnel will repair the lights as soon as possible. Thus, maintenance personnel will no longer have to make time-consuming visits to check up on the function status of every streetlight. All information is presented in the monitoring computer which is programmed in LabVIEW. The workman can easily turn on or off any streetlight by clicking on the screen.

The explosive growth of Global System for Mobile (GSM) Communication services over the last two decades has changed mobile communications from a niche market to a fundamental constituent of the global telecommunication markets. GSM is a digital wireless technology standard based on the notion that users want to communicate wirelessly without limitations created by network or national borders. In a short period of time, GSM has become a global phenomenon. The explanation for its success is the cooperation and coordination of technical and operational evolution that has created a virtuous circle of growth built on three principles: interoperability based on open platforms, roaming, and economies of scale (GSM Association, 2004a). GSM standards are now adopted by more than 200 countries and territories. It has become the main global standard for mobile communications; 80% of all new mobile customers are on GSM networks. GSM has motivated wireless adoption to the extent that mobile phones now globally outnumber fixed-line telephones. In February 2004, more than 1 billion people, almost one in six of the world’s population, were using GSM mobile phones.
