REDES DE ACCESO CELULAR Professors: Antonio Valdovinos Bardají (toni@unizar.es) Contents: The aim of this subject is to show different
wireless technologies for accesing networks. By means
of OPNET, we have carried out some software-based practices in order to
consolidate the student knowledge about GSM and GPRS technologies. We have
based these practices on the GSM and GPRS contributed models published at
OPNET web site. Practice 0: Introduction to OPNET This practice has been
thought as an introduction for students that never have used OPNET. We
explain all the editors contained in OPNET IT Guru 10.5. Practice 1: GSM (I) Study of a We
study the power received for different MS trajectories and we analyze the
signalling process of attaching a MS to the GSM network. During all
simulations the MS is at IDLE state, that is, it does not emit nor receive a
call. Practice 2: GSM (II) Study of a Mobile Station at Similar
to the previous one, but now the MS can either emit or receive calls. Practice 3: GSM (III) Study of the Handover process We
analyze the signalling process and the different kinds of Handover. Practice 4: GPRS Study of the main differences between GPS and GPRS We
pay special attention to the Location Update process. OPNET
