The Trimble Thunderbolt® PTP Grandmaster Clock is designed for wireless networks requiring phase synchronisation. The GM100 provides continuous availability of UTC traceable time for phase synchronisation, a must for LTE-Advanced networks and services. The Thunderbolt PTP GM100 employs industry leading Trimble GNSS solution & holdover technology.
The PTP GM100 can tolerate harsh environmental conditions supporting both indoors & outdoors deployments with extended operating temperature range.
Small cell phase synchronization
The Thunderbolt PTP GM100 is designed with small cells in mind but also it meets Marco base station requirements for synchronization.
The Thunderbolt PTP GM100 supports small cells networks that require phase synchronization. The most efficient way to implement phase synchronization for LTE & LTE-A services is to deploy the grandmaster clock close to target eNodeBs to ensure 1.5 us of phase alignment.
By reducing network hops between the grandmaster and eNodeBs, the risk of network reconfiguration and load variance on IEEE-1588 signal quality is reduced. The Trimble GM100 suits this strategy perfectly due to its small size, low cost, superior accuracy & reliability and flexibility of deployment options.
Ideal for LTE-A services
CoMP, eICIC, eMBMS and Carrier Aggregation services require that synchronization networks be requalified and redesigned to support phase synchronization. Non-compliance with phase sync specifications will result in low or no service from LTE-A equipment and degraded bandwidth leading to potential service outages.
By engineering current networks to support phase synchronization, LTE-A services downtime can be mitigated. Phase synchronization can easily be supported by current sync networks with the GM100 by adding it where needed. Given its low cost, it can be added to any network requiring support for the stringent phase synchronization specifications that LTE-A services require performing at their optimal levels.
NEBS compliance assures that the GM 100 can be deployed in edge and/or aggregation networks.
