1- how much backhauling can affect the latency and how to check it?
Ans : Depends on the techs multiplexed,please check packet loss on the TX links
2- can radio parameters affect the latency stability and how to check it?
Ans :Radio we use standard parameters,so NO.However,poor radio conditions might affect
3- does core parameters affects the latency and stability of network and how to check it?
Ans : Same as Ans 1,check Core TX links
4- what are the counters or the method to check the latency of 3G IP network from NodeB side?
Ans : Check IuB Counters
5- how can I enhance UE latency and make it stable?
Ans : Please do a route trace and check latency for each interface & compare with the standard.You will find the faulty interface
