Application Note, White Papers, Case Studies & Presentations

Wireless backhaul networks have rapidly shifted from circuit switched to packet switched technologies to meet the exploding demand for bandwidth, but whereas ciruit switched TDM networks carried precise frequency synchronisation throughout the network at the physical layer, packet switched networks based on asynchronous Ethernet cannot provide such deterministic sychronisation services.  This can cause problems for operators, since access platforms such as cellular base stations, have traditionally relied on sync delivered over the network backhaul connection to assure high QoS for end user applications.  A key factor n the evolution from circuit to packet based backhaul in telecom networks is the ability to deliver reliable carrier grade sync to wireless base stations and other access platforms.
