4 High-frequency technology High-frequency technology often used systems for the wireless transmission information such as voice, data video. GPS GPS, Global Positioning System, satellite sys- tem for determining location. SAT-TV Like GPS, SAT-TV uses satellite system for transmis- sion and used for transferring analogue and digital TV programmes.2. Possibly the best-known application this technology navigation systems. UMTS/LTE The Universal Mobile Telecommunications System (UMTS) allows much higher data rate than GSM. therefore very versatile. However, also offers the possibility circuit- switched and packet data transport. can used for classic voice transmission but also for data, sig- nalling and positioning services. The service also used authorities and organisations performing safety and security tasks (BOS).3. This section introduces several of the best-known technologies: GSM GSM stands for Global System for Mobile Communic- ations and global standard for all-digital mobile communications. used primarily for pure tele- phony between mobile telephone subscribers. GSM was intro- duced Germany 1992.3.

LTE also used for supplying broadband data services rural regions eliminate blank spots, i. This third-generation standard permits transmission speed Mbit/s with HSDPA+ 300 Mbit/s with the fourth-generation standard, LTE (Long Term Evolution). TETRA/BOS TETRA standard for digital trunked radio and stands for “terrestrial trunked radio”.e. areas with less than Mbit/s data connection
