Mobile Backhaul Optimization

2,669 views

Published on

Mobile network operators have a network congestion problem. The expansion of their services and continued wireless broadband growth, paired with ever increasing smartphone usage for social networking, entertainment and commerce, has caused a huge increase in bandwidth consumption. This rise in bandwidth consumption has led to network congestion, which, if not alleviated, can result in customer dissatisfaction and churn. Bandwidth optimization is an attractive option because it can increase capacity very quickly within the backhaul segment of a deployed network. Optimization can boost efficiency, reduce CAPEX and OPEX costs and deliver efficient use of current infrastructures. It can also help with customer satisfaction and retention, as well as provide the ability to support more subscribers and rollout of new services while bandwidth costs stay the same.
