The success of mobile broadband calls for changes to the radio access and backhaul network architectures. And technical adaptation is needed alongside the support of new business models. The article gives an overarching perspective on backhaul for the radio network. Proceeding from individual operator requirements, it examines the main architectural and technology choices and suggests a path for evolving toward packet transport.

The MSC-S Blade Cluster substantially increases node availability and the server capacity of Ericsson’s mobile softswitch solution. It also dramatically simplifies the network, creating infrastructure which is always available and easy to manage, and which can be adjusted to handle increases in traffic and other changes.

Researchers have measured the performance of LTE in the field using different drive routes and radio channel environments while traveling at velocities of up to 120km/h and at distances of up to 4km. The trials included measurements of both 10 MHz and 20 MHz bandwidths and of different antenna configurations up to 4×4 MIMO. The researchers have also measured layer-1, UDP and TCP throughput using two kinds of terminals: the LTE test bed and a prototype handheld terminal.

Operators can employ machine-learning techniques to exploit user, network and traffic data assets to better understand their subscriber base and to analyze network traffic and media files. They may also apply these capabilities to boost services or to identify why users do not adopt them.
