wireless technology is an essential technology to be launched to meet the
rising demands of more connected devices, higher data speeds, rapid response
times and high quality of service (QoS). To meet these requirements
cost-effectively, an entirely new network architecture must be deployed.
Essential to the network architecture will be a Centralized Radio Access
Network (C-RAN) where Baseband Processing Units (BBUs) are separated from
Remote Radio Heads (antennas - RRHs) and physically or virtually centralized in
order to increase efficiency and cost-effectiveness.
To bring down bandwidth requirements between
the BBU’s and the RRH’s several standards are proposing splitting the radio
protocol stack, so that parts of the L1/PHY processing is taking place at the
RRH side. In addition to splitting the radio protocol certain standards are
also applying different compression schemes to further reduce the bandwidth.
