Samsung upgrades C-RAN to cope with data spikes

News

Samsung has brought baseband capacity pooling and clustering to its C-RAN product, which it said offers operators more dynamic capacity management.

The electronics company has developed a new switch for its C-RAN2.0 solution, which allows traffic to be dynamically routed between cell sites and centralised baseband units (BBUs). It said BBUs can be deactivated when the network is not being heavily used, reducing an operator's energy costs. 

The switch is part of its baseband pooling feature, which allows an operator to bring together its network resources across a large number of cells and offers a capacity management function.

Samsung said pooling could be used to cope with unexpected data spikes amid large numbers of people, such as at sporting events or concerts.

A new clustering function allows BBUs to be coordinated, which Samsung said would improve cell edge performance and help bring about scheduling features such as coordinated multi-point and inter-site carrier aggregation. It also allows a device to pick the best signal from across a range of different cells, increasing the quality and consistency of the network's performance.

Joonho Park, Senior Vice President and head of Global Sales & Marketing, Networks Business, said: “Samsung’s C-RAN2.0 is well-suited for city deployments where there are constraints in site procurement despite continuing demand for improved network coverage and performance.

"In these situations, densification is a high priority, and C-RAN is optimally designed to enable rapid deployment with a significantly smaller footprint that a traditional distributed base station. C-RAN2.0 adds another level to this by introducing significant and competitive capability enhancements to the C-RAN architecture.”
