Abstract: This paper reviews existing Femtocell architecture deployment options proposed by the 3GPP, highlights the increase on data consumption expected in the home environment and proposes a simulation study to assess the achievable QoE with each one of the proposed architectures taking into account the backhaul technologies. 1 Introduction In recent years the Mobile Network Operators (MNOs) in UK and the rest of the world have seen an exponential increase in the data consumption over their networks. This is due to the success of what is called “Mobile Broadband” contracts for laptops, which consume 100 times more data than a normal mobile device, the appearance of high-end smartphones which consume 8 times more data than a normal mobile device and the introduction of “all you can eat” data plans. These disproportionate increase of data consumption [1] is not followed by a similar revenue increase as in developed areas the penetration of the mobile market is already close the maximum possible and competition is driving the prices down. 1. Cisco Forecasts 3.6 Exabytes per Month of Mobile Data Traffic by 2014[1] One of the options the MNOs have is to start the deployment of 4G or 3.9G technologies like LTE, but even that won’t be enough, because according to Cisco, mobile data traffic is expected to grow 20 times over the next 5 years [1]. Because the great majority of the data is consumed at home and this trend, as the graph below shows, will continue to increase, and because the high frequencies currently in use offer bad coverage indoors, operators will have to offload traffic to smaller cells to solve the issues of coverage and to increase the user data allocation[2]. 2.
