Can Wi-Fi be used for wireless voice return?

As operators are facing almost crazy demands for mobile data, data congestion may occur in at least four different fields, including: · Wireless Access Network; · Network Signaling and Control; · Grouping core networks; · Return network. Each type of bottleneck is a special challenge for operators. One of the following three methods can be used to solve the problem: 1.Increase the capacity of the affected network resources; 2.Distribute network resources to relieve congestion; 3. Take the above

"Heavyweight" uncover the performance of mobile networks (in)--specific explanations for mobile network components

Simple IntroductionOver the past few years we have made significant progress in mobile cellular network performance. But because of the expansion of network latency, many applications have not been improved.Latency has long been a constraint on mobile networks. While some progress has been made in recent years, the reduction in network latency has not been keeping pace with the delayed growth rate. It is because of such an incorrect delay, rather than
