Mobile Backhaul Solutions

Programmability and Precision Time Solution Key to Sound Business Case

Mobile backhaul networks are evolving to packet-based high-capacity Carrier Ethernet networks. As 3G and LTE pave the way to heavyweight mobile broadband, service providers are looking to increase bandwidth, reduce operational cost and preserve synchronization.

Xelerated's mobile backhaul solutions can be applied in the 1st stage (sometimes referred to as 1st landmile access) and aggregation part of the mobile network.

Xelerated’s technology suite for mobile backhaul leverages the same programmable Ethernet switches as used in the unified fiber access solutions. The aggregation part of the network shares network processors and data plane software with the Metro Ethernet solution. 

Support for Synchronous Ethernet and Precision Time Protocol offers scalable base station synchronization services. The X11 and HX network processors and the AX programmable Ethernet switches enable a common design approach for data plane implementations on a range of products. This allows for a truly unfied approach to the quickly growing mobile backhaul and fiber access markets. Programmable devices with superior integration levels enable healthy product margins and quick time-to-market.

Target Systems

• 2G/3G aggregation backhaul switches / UTRAN switches
• LTE backhaul switches / e-UTRAN switches
• PTN mobile backhaul switches
• Microwave aggregation switches
• CES switches
• WiMAX aggregation switches
