Performance and Enhancements of Second Generation Systems: GSM and DECT
نویسندگان
چکیده
This chapter reports on some of the work carried out in COST-231 with relation to second generation personal communication systems, and specifically GSM and DECT. The performance of basic versions of such systems is relatively well known, and the focus of the work was therefore on advanced features and possible limitations. These topics are of importance not only in relation to the full exploitation of the potential of the systems, but also in terms of possible evolutionary transitions towards the third generation via progressive enhancements of the radio and network performance.
