    Product description

    DTS201A Master Clock

    PTP master clock is desianed for wireless networks that need phase synchronization.DTS201A provides continuously available UTC tracesynchronization, which is a prerequisite for LTE-Advanced networks and services.DTS201A Adopt industry-leading GNSS solution and punctual technology..TS201A can work in harsh environmental conditions. support indoor and outdoor deploymen. and has a wide workng temperature range


    Small cell Phase synchronizatior

    While designing DTS201A for small stations, it also considers and meets the time synchronization requirements of Acer stations.PTP DTS201A lt can be used in smal station networks that need phase synchronization.The most efective way to realize the phase synchronization of LTE and LTE-Aservices 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 ime server and the LTE base station, the isk of the impact of network reconfiguration and oad changes on ieee1588 sional quality can be reduced.DTS201A perfecty adapts to this strategy because of ts smal volume, ow cost, high precision, excelent reliabiy and adapiabity


    LTE-A Ideal for service

    CoMP,elcic,eMBMS and Camier Aggrenation service requires re authenticaton and redesian of synchronization network to supoort ohase synchronization functionFailure to comply with the phase synchronization specification wil lead to serice degradation or failure of LTE-A equiomen, and reduce the bandwidth.resutino inpotential service interruption.

    By desining the curent network to support phase synchronization, the pause time of LTE-A service can be reduced.Adding DTS201A can easiy add phasesynchronization to those synchronization networks. n view of its low cost, t can join any network node that needs to support strict phase synchronization function. so asto bring the best performance for LTE-A service

    High reliability ensures that DTS201A can be deploved in boundary or aggregation networks
