Centralized Radio Access Networks
As you’ve learned, Distributed Radio Access Networks have issues with cost, wasted capacity, and inefficient use of radio frequencies. As a result, telecoms companies are looking for good alternatives that will meet future consumer needs. One of the most promising and powerful technologies is the Centralized Radio Access Network, or C-RAN.
Differences Between C-RAN and D-RAN
The main difference between C-RAN and D-RAN installations is in how the baseband units (BBUs) are configured. In D_RAN technology, the BBUs are each located at the base station and act independently – in C-RAN, the BBUs are stored in one central location.
Moving the BBUs like this creates a “Fronthaul Architecture” and increases the distance between the BBU on one end (in the centralized location) and the antennas, remote radio heads, and fiber feeder on the other (in the base station).
