Product description

DTS201A Master Clock

PTP master clock is designed for wireless networks that need phase synchronization. DTS201A provides continuously available UTC traceability time for phase synchronization, which is a prerequisite for LTE-Advanced networks and services.
DTS201A Adopt industry-leading GNSS solution and punctual technology.。
DTS201A can work in harsh environmental conditions, support indoor and outdoor deployment, and has a wide working temperature range.

Small cell Phase synchronization
While designing DTS201A for small stations, it also considers and meets the time synchronization requirements of Acer stations.
PTP DTS201A It can be used in small station networks that need phase synchronization. The most effective way to realize the phase synchronization of LTE and LTE-A services is to deploy the master clock near eNodeB to ensure the phase synchronization of 1.5 us.
By reducing the number of network hops between the time server and the LTE base station, the risk of the impact of network reconfiguration and load changes on ieee-1588 signal quality can be reduced. DTS201A perfectly adapts to this strategy because of its small volume, low cost, high precision, excellent reliability and adaptability.

LTE-A Ideal for service
CoMP,eICIC,eMBMS and Carrier Aggregation service requires re authentication and redesign of synchronization network to support phase synchronization function. Failure to comply with the phase synchronization specification will lead to service degradation or failure of LTE-A equipment, and reduce the bandwidth, resulting in potential service interruption.
By designing the current network to support phase synchronization, the pause time of LTE-A service can be reduced. Adding DTS201A can easily add phase synchronization to those synchronization networks. In view of its low cost, it can join any network node that needs to support strict phase synchronization function, so as to bring the best performance for LTE-A service.
High reliability ensures that DTS201A can be deployed in boundary or aggregation networks.
