The NGMN Alliance has released a white paper titled "Guidelines for LTE Backhaul Traffic Estimation." The paper provides guidelines for estimating the traffic on LTE backhaul networks. The document is intended for use by mobile network operators and other stakeholders involved in the development and deployment of LTE networks. The guidelines are based on the experiences of the NGMN Optimised Backhaul Project Group and cover various aspects of backhaul traffic estimation, including the factors that influence traffic, the methods for estimating traffic, and the challenges associated with traffic estimation. The paper is available for download on the NGMN Alliance website.
