Network assisted synchronization service platform

Its low latency pass-through technology enables an upgrade of existing installations in form of low cost add-on dongles, or, becoming part of new designs by replacing some generic standard parts found in all network equipment.

The increase of subscribers and new mobile services inevitably leads to an increasing number of subscriber access points in the cellular networks. For a large scale network with many small cell sites a synchronization service of high quality means better user experiences and a higher utilization of the frequency spectrum allocated to provide services to the increased number of subscribers. Coordinating the time and phase will be crucial when new generation small cell products will operate within the same geographical coverage as the macro cells previously deployed. The new LTE-A standards call for methods to more accurately synchronize the nodes, but the business case for better time and phase distribution can be proven also for existing 3G networks.

Ola Andersson CEO of Conemtech, comments: “Our design philosophy in the making of the M60 is to provide large networks with a number of available synchronization methods in a low cost form to effectively synchronize a massive number of nodes. This can only be achieved by miniaturizing the technology and making it replace other components with it’s budgets and footprints. With the M60 we have chosen the physical layer interface component, the PHY, as the main device to replace besides the oscillator. Wrapped in our instantPTP product packaging with transparent and clear interfaces, the advanced features of the M60 can be used by all designers of network capable equipment, both in telecom and smart power grids which share some similar inherent properties.”
