DTS201A Master Clock
PTP master clock is desioned for wireless networks that need phase synchronization.DTS201B provides continuously avalable utc traceability time for ohastsynchronization, which is a prerequisite for LTE-Advanced networks and services
DTS201B Adopt industry-leading GNSS solution and punctual technology.
DTS201B can work in harsh environmental conditions. support indoor and outdoor deployment, and has a wide working temperature range
Small cell Phase synchronizatior
While designing DTS201B for small stations, it also considers and meets the time synchronization requirements of Acer stations.
PTPDTS201B 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 time server and the LTE base station, the risk of the impact of network reconiquration and load chanoes on ieee-588 siona ouaiy can be reduced.DTS2013 perecty adapis to this straieay because of ts smal volume. ow ost. hih precision. excelent relabiy and adantabitv
LTE-A Ideal for service
comP.elcic, eMBs and Carier Aaareoation service reuires re authentication and redesin o synchronizaton network to support phase synchronizaton funcion
Failure to comply with the phase synchronization specification wil lead to service dearadation or ailure of TE-A equioment. and reduce the bandwidth. resulting in potential service interruption.
By designing the curent network to support phase synchronization, the pause time of LTE-A service can be reduced. Adding DTS201B can easiy add phase synchronization to those svnchronization networks, n vew of its loy cot, t can oin any network node that needs to supoort stict phase synchronizaton tunction. so as to bring the best performance for LTE-A service.
High reliability ensures that DTS201B can be deployed in boundary or aggregation networks
