For this post, we will be updating it continuously with different techniques and measure that any RF engineer can apply to improve the LTE RF access performance.
Case 1: Access failures due to IPPATH misconfiguration
During a routine check, RF engineer found that one site was showing a degradation of eRAB access success rate and the increase of access failures due to Transport Network Layer. This failure counters as its name says, it is usually related to issues in the transport / transmission layer. For this case, the first step we should follow is to review the performance on the S1 interface.
