Abstract [en]

To meet the increasing demand of bandwidth, connectivity, mobility and the change of user profile (more data oriented), the network is expected to follow this trend. WLAN access points are deployed constantly, and taking advantage of them can be a solution. This project investigates the solution where the WLAN access point uses the WCDMA as a backbone and the performance of this combination. Moreover access selection algorithms in the two hop system (load balancing in the mobile to access point and a geographical dynamic load balancing in the access point to the base station) are presented and the performance in the uplink are studied The results showed an improvement in the number of the satisfied users from 7% to 30% depending on algorithms are activated. Those performances were studied in two different scenarios: a user deployed access point, lightly loaded with 128 Kb/s in the uplink, and an operator deployed in hot spots with a 32 Kb/s in the uplink too.
