Small Cell Backhaul Performance Assurance
Information Resources | 7/9/2014 |
There is no doubt we are attached to our mobile devices, to the point where they now outnumber the global human population. Mobile data will increase 1000-fold between 2014 and 20201, with users expecting service quality to keep in step. RF capacity has its limits, and is unable to keep up with demand unless a new radio access model emerges.
Mobile access networks are strained to maintain quality as more subscribers run bandwidth-intensive applications from a variety of devices. With the annual throughput of mobile traffic expected to increase from 58 Exabytes in 2013 to roughly 335 Exabytes by 20202, brute-force over-provisioning of bandwidth is no longer an economically feasible solution. Operators must implement strategies to meet growing quality of experience (QoE) expectations even in the face of finite spectrum.

A Concise Guide to Mobile Backhaul Synchronization White Paper
Information Resources | 7/3/2014 |
As the Mobile Backhaul increases bandwidth between radio equipment and core networks to keep up with demand, legacy TDM links are being replaced by more efficient Ethernet links. However, with packet switched networks (PSN) being inherently asynchronous, the question arises as to what could fill the void of providing the tight frequency and phase synchronization required by the mobile base stations and other real-time applications.
Several technologies like IEEE 1588v2 Precision timing protocol, ITU-T G.8261 Synchronous Ethernet and GPS-disciplined clocks are currently available to fill that gap. Since each one has its strengths and weaknesses, and solutions may include a combination of them, Mobile Backhaul Synchronization is currently a hot topic being studied and discussed by standardization bodies and service providers' labs around the world. This white paper provides a concise guide to these new synchronization techniques, with an emphasis on the IEEE 1588v2 Precision Timing Protocol (PTP).
