A portrait of a GPRS/GSM session
2003Some results from a GPRS/GSM traffic measurement are presented. First we define session arrivals, durations and volumes in such a way that they can be compared, for example, with measured values of dial-up sessions. Then we study the map of cumulative volume of a single session against elapsed time from the first observed packet of the session.

2nd European Conference on Antennas and Propagation (EuCAP 2007), 2007
Slotted PIFA with capacitive loading for operation in the GSM band is presented. The PIFA is placed on a ground plane with dimensions of an average handheld device. The antenna is optimized by using electromagnetic simulator and a prototype is manufactured. Calculated and measured results agree very well.

Interoperability of PDC with GSM
Proceedings of ICUPC '95 - 4th IEEE International Conference on Universal Personal Communications, 2002Currently many countries employ GSM as their cellular systems. In Japan, a PDC cellular system has been introduced. The number of PDC users is increasing significantly, and some PDC users need to roam to a GSM network and vice versa. However, there are some technical incompatibilities between PDC and GSM.

Massive enhancements have been introduced in the GSM platform, in the area of both data and supplementary services and for the support of operator specific services, in order to fulfil the increasing customer demand. On one hand, the introduction of the new services sometimes imply a considerable modification to the network architecture and ...

In the last years the Global System for Mobile communication, GSM, has gained a tremendous success around the world. Meanwhile more than 250 operators offer their GSM services to over 66 Mio customers in 110 countries. Before this success could be imagined, work was started in ETSI to specify first drafts for the interworking of Digital Enhanced ...

2014 Fourth International Conference on Advanced Computing & Communication Technologies, 2014
In traditional methodology to find the motion of human we have some devices like video camera, radar, ultrasonic sensor etc. In case of video camera another human have to continuously monitor the video. If we use radar or ultrasonic sensor, we need a transmitter and a receiver.

In this presentation, the mobile satellite service (MSS) is regarded as complementary to the corresponding terrestrial systems. The MSS may offer an outdoor service extension to the terrestrial mobile systems. This can be achieved with appropriate integration of the satellites with the terrestrial system.

IEE Review, 2002
The author reports on how a UK company-with a little help from Category 5 cabling-is helping to realise the commercial potential of the GSM pico base station. ip.access, a Cambridge technology start-up is the supplier of the world's smallest GSM base station, the nanoBTS (base station transceiver), measuring a mere 210 mm by 280mm.
