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

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.

Arduino Based Smart Energy Meter using GSM
International Conference on Internet of Things, 2019India faces the issue of energy theft at a very large scale. This paper introduces a system that removes human intervention in meter readings and bill generation thereby reducing the error that usually causes chaos and energy related corruption.

IEEE transactions on electromagnetic compatibility (Print), 2018
Based on 2.5-dimensional (2.5-D) structure, a novel compact dual-band frequency selective surface for GSM shielding is proposed in this letter. The unit cell geometry is designed by knitting double square-loop elements in 2.5-D which realizes the compact

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.

Study of GSM system performance by a GSM network computer simulator
1992 IEEE International Conference on Selected Topics in Wireless Communications, 2003A 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.

Measurement of GSM phone emission
Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat. No.04CH37510), 2004GSM (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.
