Abstract	The evolved UTRAN architecture is expected to sustain data rates of around 1Gbps to handle the multimedia traffic expected in 4G systems. The multifarious services promised in the new generation networks, coupled with high speed data transfers impose great strain on the few network elements that perform these services, due to the flat architecture. There is a need for a reliable topology interconnecting eNBs which distributes this heavy load as well as renders the network immune to S1, X2 link damages. In this work, we propose a new RAN topology for LTE-Advanced systems that is robust to link damages. We compare this with the current standards in LTE. This comparison is expressed as Average Number of Towers Lost, in the event of link damages in the EUTRAN. We then test the flexibility of the topology in terms of the Average Change in Hop Count. We proceed to show that this new RAN structure is compatible with LTE Advanced technologies like CoMP. We also show how it reduces load on the MME and the SGW and helps provide a platform for better synchronization between eNBs.
