Abstract

Recently multiple radio access technology (M-RAT) has been suggested as a solution to provide the currently congested wireless consumers with higher throughput and therefore improved performance mainly through offloading cellular traffic to alternative networks such as WiFi and femtocell. In this paper, we investigate analytically where M-RAT can accomplish this task. Specifically, a throughput comparison will be made between those users, who can benefit from M-RAT capability and those who cannot. More specifically, we consider three important scenarios: (1) simultaneous connection to WiFi and macrocell, (2) simultaneous connections to two macrocells, and (3) simultaneous connection to WiFi and femtocell. The main results of the analysis reveal that multiple connection capability improves the performance by increasing multiplexing gain, mostly observable when cells with access point of comparable size overlap completely.
