PMC extends leadership in mobile backhaul with WinPath4 processor optimized for LTE

USA: PMC has introduced WinPath4, the industry’s first backhaul processor that enables mobile operators to scale capacity in their backhaul networks while transitioning to Layer 3 Packet Transport Networks (PTN).

As the newest member of PMC’s leading WinPath backhaul processor family, WinPath4 eliminates network bottlenecks caused by the growing deployment of 4G LTE.

The proliferation of smart mobile devices and growing demand for higher data rates are driving carrier migration to LTE technology. As LTE backhaul networks are deployed, carriers are eliminating the radio node controllers (RNC) used in 3G deployments and distributing the controller function across base stations.

This requires migration from a Layer 2 centralized hub network to a Layer 3 mesh IP topology with intelligence at each base station. WinPath4’s unique, programmable Carrier Ethernet Router-on-Chip architecture allows system vendors to provide new platforms that enable this transition.
