Capacity analysis of heterogeneous wireless networks under SINR interference constraints

Next Generation Wireless Networks (NGWNs) are expected to be heterogeneous, which integrate different Radio Access Technologies (RATs) such as 3GPP's Long Term Evolution (LTE) and Wireless Local Area Networks (WLANs) where a transmission is supported if the signal-to-interference-plus-noise ratio (SINR) at the receiver is greater than some threshold. In this paper, we analyze the interference in heterogeneous wireless networks and determine the capacity by taking into consideration the class of traffic of each call and considering both intra-network interference and inter-network interference. This analysis allows us to simplify the estimation of capacity under SINR interference constraints in different wireless networks.
