Artiza Networks, Inc. announced the launch of Advanced C-RAN (Centralized RAN) Test Solution for LTE-Advanced. Advanced C-RAN is a new technology developed by NTT docomo, and it is scheduled for the first deployment in 2015. Advanced C-RAN uses Carrier Aggregation technology, one of the major features of LTE- Advanced defined by 3GPP, and it performs precise coordination of macro cells and small cells for combining broad connectivity and high throughput.

In this architecture, small cells are overlayed on to macro cells, and Carrier Aggregation technology is used to combine radio resources and to improve the entire throughput. Macro cell's large coverage area maintains stable connectivity, and network capacity is increased by small cells.
