Abstract

This paper deals with a QoS in 802.11 WLAN (Wireless Local Area Network). WLAN networks provide highest speed of data rate at low cost. However, mobility is not present in WLAN or its services are available in a small geographical region. Universal Mobile Telecommunication System (UMTS) is deployable for large areas but it cannot provide sufficient data rate as compared to WLAN, however, cost is also high. To remove these drawbacks the integration of WLAN and UMTS can be a better solution for present needs. The integration of these two technologies provide: better quality of service, load balancing, large geographical area with high data rate at low cost to wireless clients. The data type used is Multimedia data which is hence used to meet the current business needs as well as is required for the collaborative growth of the networking arena. The integration techniques of WLAN and UMTS are based on coupling: open coupling, loose coupling. There is still an uncertainty which remains about the functionality and performance of the integrated architecture. Different techniques are hence been compared in this paper such a result is obtained which will solve our issues and is feasible for the usage of all users.
