Mobility and traffic parameters for simulating interoperating UMTS and HIPERLAN/2 MTMR enabled networks

Fourth generation wireless networks (4G) are expected to provide ubiquitous wireless communications at high data rates and a large variety of services, as their main feature is the interoperability and seamless roaming between wireless local area networks (W-LANs) and third generation mobile networks. This paper focuses in the system level issues of simulating a 4-G network with the multiple transmit-multiple receive (MTMR) transceivers for interoperating UMTS and HIPERLAN/2 networks. User behavior is addressed in terms of mobility and traffic characteristics. Existing user data from a GSM-GPRS operator (COSMOTE) have been used in order to extract the parameters to be used in the simulations. Two hotspot scenarios - an airport and a city center environment - are identified and analyzed.
