FH-GSM frequency hopping GSM

Proceedings of IEEE Vehicular Technology Conference (VTC), 2002
The GSM system of today is evolving towards smaller cells and higher traffic capacity. The need for microcell and even picocell systems will be greatly increased in the near future. One of the most important factors will then be to provide high traffic capacity and to provide an easy way of performing frequency planning for the system operator. In this

An evolution of GSM

Proceedings of IEEE Vehicular Technology Conference (VTC), 2002
The third generation systems (e.g. FPLMTS) aim at fulfilling high requirements on flexibility, capacity, quality, coverage and cost. Long before the introduction of the third generation systems their need will be challenged by evolution of the existing cellular systems.

The evolution of GSM

1994
GSM is now a fully evolutive systems, a platform which can accept improvements, new features, or modifications needed to adapt it to something which was not foreseen from the start. This is important for companies operating a GSM network, which can expect that there investment will be a sufficiently long-term one, but also to conquer new markets.

Measurement of GSM phone emission

Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat. No.04CH37510), 2004
GSM (Global System for Mobile Communications) phones are part of everyday life. Their emission level is an EMC (Electro-Magnetic Compatibility) issue. It is important to know the peak signal levels of the mobile phones. They can cause interference with other electronic devices.

Study of GSM system performance by a GSM network computer simulator

1992 IEEE International Conference on Selected Topics in Wireless Communications, 2003
A simulator (GSMSIM) of the digital cellular radiotelephone network, GSM, is described. The simulator is used as a tool for network design. The GSMSIM supplies: the load of the cells, the frequency and length of the calls in the cells, the number and place of the handovers and their reasons, and also power control parameters.

A 3V GSM codec

Proceedings ISSCC '95 - International Solid-State Circuits Conference, 1995
Designed to satisfy the data conversion requirements of the Pan-European (GSM) cellular radio system, the chip is part of a four chip-set total GSM solution comprising the codec, the DSP, the digital ASIC, and the micro-controller. Fabricated in a 0.8 /spl mu/m double-poly, double-metal CMOS process, the integrated circuit combines a voiceband codec ...
