Performance analysis of a layered wireless network serving different user classes

This paper analyses the performance experienced by different user classes that offer traffic to a layered wireless network. The impact of the proportion of each user type on the blocking probability experienced by the three classes and the network capacity in Erlangs for a given grade of service (GOS) are analysed for networks of one macrocell with 25 and 50 microcells respectively. The classes describe different users in a general sense and could equally apply where users are distinguishable either by multimode terminals, multiband terminals, by subscription options or where coverage defines distinct classes. The results give valuable insight into system performance and network capacity with the different user classes.
