As one of the mainstream technologies of IMT-Advance, TD-LTE helps the world go into the era of mobile broadband network. Compared with the existing 2G and 3G mobile communication systems, TD-LTE raises the demands for high bandwidth, low latency, horizontal forwarding, and terrestrial transmission of time synchronization information in backhaul network. The TD-LTE air interface needs to synchronize in high accuracy to transmit high-precision time synchronization signal in the TD-LTE backhaul network.
With the continuous evolution of 2G, 3G and 4G wireless networks and from SDH network to packet based network, the synchronization requirement is not only in frequency field, but in both phase and frequency fields. Therefore, telecom operators are now paying more and more attention to the performance of high-precision time and clock synchronization devices.
In view of time and frequency synchronization measurement on various devices like time server, PTN, Base Station in 4G network, we provide comprehensive test solutions with time signals such as PTP, 1PPS, 1PPS+TOD, and frequency signals such as 2.048MHz,2.048Mbit/s, SyncE.
