In 5G mobile networks, stable network operation and preventive maintenance are keys to achieving 5G innovations including low latency, high speeds/large capacity, and multiple simultaneous connections.
For the 5G systems engineer, implementing three key elements of 5G (low latency, high speed and large capacity, and multiple simultaneous connections) is expected to facilitate rollout of new applications in fields such as self-driving vehicles, remote control of heavy machinery, ultra-high-definition video streaming, telepresence at sports events, etc.
Implementing applications to take advantage of low latency, high speeds, large capacity, and multiple simultaneous connections requires a communications technology paradigm shift from 4G to 5G.
Additionally this requires a simultaneous technical revolution for 5G mobile networks from 4G (LTE).
A key requirement of a 5G systems engineer is measuring and maintaining 5G mobile network latency requirements.
Since maintaining minimum assured communication speeds is generally impossible using Ethernet, latency times of the entire network including the 5G mobile fronthaul must be managed strictly.
To suppress latency times between the mobile fronthaul 5G antenna and Core/Metro network, it is important to minimize the latency of the network equipment as much as possible.
Implementing the 5G low-latency feature generally requires using two testers to accurately measure one-way delay between two distant separate points.
Network time synchronization measurements are also critical. Use of the 5G mmWave band requires many small base stations because the high radio-wave frequency only propagates over short distances. As a result, the Precision Time Protocol (PTP) is used to synchronize time between base stations. Time synchronization using PTP demands strict evaluation of the entire network to maintain time differences within the permissible range
