Why is MMBI uniquely qualified as the Backhaul solution? � Amazing flexibility – Supports both legacy mobile backhaul networks as well as future technologies such as LTE. � For example, the same MPLS network infrastructure can be used to carry the legacy traffic pseudowires, may also be used to carry and provide QoS guarantees to next generation LTE traffic. � Investments in MPLS technologies benefit the service provider by making it “future proof” and still applicable in the fast evolving mobile technology scenarios (eg: LTE and beyond). – Deploys on any layer 2 technology capable of supporting MPLS labeled switching. – Ideally suited to overcome the scalability limitations of traditional circuit based technologies such as ATM and TDM. � MPLS permits support of these technologies using pseudowires to protect existing investments in legacy equipment. For future IP and Ethernet based interfaces, it is possible to aggregate traffic over single TE tunnels and provide differentiated services for this aggregate so that QoS requirements are met while at the same time providing further improvements in scalability. – Provides economies of scale. � Leverages the MPLS network to meet the requirements of not only the diverse set of mobile backhaul technologies but also to those of other applications, the MPLS network also. � This provides significant reduction of capital and operational costs.
