Premises from Childhood and Adolescence,n reuse distance. In GSM, the fact that the number of nearby cochannel interferers is relatively small leads to a high probability of a dominant interferer (DI). Hence, suppression of DI alone provides substantial capacity improvement for GSM. The paper summarises different aspects of interference s

Barbarin house and my first funeral,d quality requirements are dramatically increasing. Random Frequency Hopping (FH) in digital F/TDMA systems like GSM and its derivatives is a method of expanding the bandwidth used by a traffic channel, thereby creating frequency and interference diversity effects. In this article, the capacity gain

This chapter presents a set of models that can be used to determine the coverage expected from an antenna in any given environment. With the antenna being closer

A Life of Experimental Economics, Volume IIteristics and, consequently, different solutions are needed. At homes, the key issue is the cost of the base station. To meet the low-cost requirement, a MS based HW architecture for the base station is needed. The usage of only few timeslots instead of eight will cause the air-interface to change.

Realization Theory and Algorithms, 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 Cordless Telecommunications, DECT, to GSM. The extension of GSM using DECT as a complementary air inte

Any radio access technology can be interfaced with the GSM/UMTS core network, the most dominating core network globally..In Europe UMTS air interface will be selected in the beginning of 1998. The target has been and still is to select only one air interface. Therefore, from the
