The customer premises equipment (CPE) provides connectivity between the access network and the home network. In the current wireline network architectures, the CPE consumes more power per user than any other element in the network. Considering the large number of users, CPE is an important contributor to the overall carbon footprint and hence it should be designed with energy efficiency in mind. In this project, we will investigate several CPE architectures (passive/quasi-passive) along with several wireless home network architectures to find the best possible combination that minimizes the end to end energy consumption. In addition, the CPE to be designed shall have the capability to route the traffic between the cells in the wireless home network without sending that traffic to the central office.
