Technical Brief: Next-Generation Wireless Backhaul Solutions

Mobile operators are currently experiencing rapid growth in data services along with a steady growth in voice traffic. However, the voice market is extremely competitive and revenue growth is slow. They face the dual challenge of increasing average revenue per user and reducing customer churn. Service providers are seeking revenue and profit growth through new differentiated packet-based services. Many of these services, such as mobile Internet and mobile TV, require high bandwidth - and the current backhaul infrastructure is not optimized for handling such traffic. Hence, providers have to add backhaul capacity while keeping operational costs under control, a situation that is forcing carriers to migrate their access and core networks to the new 3G and 4G infrastructure.
