Gateway Clock enables flexible synchronization architectures for deployment of indoor and outdoor small cell coverage solutions

M68: Managed Timing Engine Module Gateway Clock

"Our forecast predicts that the market for this kind of gateway clock will grow at a cumulative rate of 60% over the next four years,” said Joe Madden, Principal Analyst at Mobile Experts.

Qulsar, Inc., a provider of precise time synchronization solutions, adds a new class of Managed Timing Engine (MTE) called the M68 Gateway Clock to it’s next generation M6X series platform. A Gateway Clock adds functions to the Boundary Clock (BC) aligned with the Assisted Partial Timing Support Clock (APTSC) architecture being proposed within ITU-T G.8272.x Time Profile. The M68 comes packed with multi-sync capability including GNSS (1 PPS + ToD), IEEE 1588 PTP, SyncE and frequency. This offers not only high performance at a low total cost of ownership, but also improves the resiliency of the solution significantly. M68 offers vendors the greatest flexibility in deployment by enabling synchronization architectures that can be widely deployed both indoors and outdoors.

Operators worldwide are considering different form factor small cell technologies to solve indoor coverage problems given the penetration challenges of GNSS signals deep inside buildings where these cells are deployed. The industry is therefore looking at synchronization solutions that deliver 16ppb for FDD, 1.5µs for LTE-TD and .5µs for LTE-Advanced by using multiple sync sources to ensure reliable and high quality of service.

Qulsar’s MTE M68 is a versatile synchronization platform that meets the stringent requirements of new evolving 4G architectures as well as offers readiness for 5G. It can be deployed as a module in small cells, board form-factor in Carrier Ethernet Mobile Backhaul equipment and as a complete sub-system in macro eNodeBs as well as standalone mini grandmasters that follow APTSC architectures. The Gateway Clock offers configuration and functionality flexibility as it is software programmable and comes with different options of oscillators for varying holdover ranges required by service providers.

"As the small cell industry shifts its focus to indoor coverage solutions, mobile network operators need to solve synchronization challenges that arise due to GNSS signal weakness indoors. Reliance on alternate sources of synchronization such as packet based IEEE 15888 PTP and/or Synchronous Ethernet (SyncE) is essential in order to deliver stringent time and phase indoors. Our forecast predicts that the market for this kind of gateway clock will grow at a cumulative rate of 60% over the next four years,” said Joe Madden, Principal Analyst at Mobile Experts.

“Qulsar is proving its commitment to continuous innovation of it’s Managed Timing Engine platform with the release of the M68 Gateway Clock. Qulsar’s field- proven PTP grand master and slave technologies have been fused with additional capabilities to introduce this comprehensive timing platform that can be deployed widely and leverages available sync signals. The platform caters to the evolving synchronization needs of not only mobile network operators but also mobile backhaul transport vendors by offering high performance, rapid time-to-market, cost effective solutions such as the M68 Gateway Clock,” said Rajen Datta, President and CEO of Qulsar, Inc.

Qulsar’s M68 Gateway Clock is available for immediate shipment worldwide.
