IP RAN

The radio access network – in particular, the backhaul connections between the base stations and their controllers – is one of the areas impacted most by the bandwidth upsurge associated with new mobile broadband services. While in the past a small number of E1/T1 links were sufficient to service 2G and some 3G traffic, the bandwidth requirements of HSPA, HSPA+ and LTE cannot be economically accommodated by TDM connections, leading operators and transport providers to migrate their access networks to IP RANs and packet-based backhaul.

The biggest challenge in the transition to IP RAN, however, is the need to ensure synchronization over packet networks. While clocking data has been transmitted natively in TDM networks, new PSNs (packet switched networks) are asynchronous by nature and necessitate specialized solutions to ensure accurate clock transfer to avoid packet delay, delay variation and packet loss.

RAD’s IP RAN Solutions

RAD’s IP RAN solutions enable carriers, mobile operators and transport providers to lower their transport costs by migrating multi-generation radio traffic to an all-IP mobile backhaul network. Powerful synchronization and clock transfer support, including 1588v2 and Synchronous Ethernet, together with end-to-end Ethernet OAM and advanced QoS capabilities ensure carrier-class service delivery and SLA assurance throughout the IP RAN.
