Overview
Traditional mobile installations are bulky (use thick coaxial cables) and
require a lot of power to operate (there is a huge power loss in the coaxial
cabling which often requires the use of Tower Mounted Amplifiers) as
outlined in the following figure.
Pressures on the Mobile Network Operators (MNO) to reduce their capital,
operational cost, and increase coverage are at the heart of a revolution in
the mobile network. To address the situation, a concept of decomposition
of the radio base station has been developed where the radio basic
functions and its ability to transmit and receive radio modulated signals are
separated. In such a distributed environment a protocol is required to
maintain synchronization and management capabilities as well as
transporting the user traffic between the simplified Base Transceiver
Station (BTS) and its Remote Radio Head (RRH).
