With an increase in the number of subscribers in wireless networks like Wireless in Local Loop (WiLL), it becomes expedient to employ spectrum reusability techniques such as the use of multihop relaying in order to improve the capacity of the WiLL system. Throughput enhanced Wireless in Local Loop (TWiLL) is one such architecture that employs multihop relaying and shortcut relaying to reuse bandwidth. Analysis of the Call Acceptance Ratio (CAR) in TWiLL is non-trivial as the Erlang B formula no longer holds. In this paper, we build multi-dimensional Markov Chains to analyze the performance of this system.
