New deployments are needed to address the
future needs of 4G networks like high data rate
support for clustered users. As a result, there is
a shift in paradigm for MIMO increasing
the number of antennas at a single cell site to
distributing multiple antennas over a cell area.
Furthermore, such distributed antennas may be
in different power levels, and also in different
antenna configurations. These add an interesting
aspect and require scalable designs as well as
interference management as part of MIMO
improvements. Geographically separated antennas
implemented as remote radio heads can be
controlled by a centrally located baseband unit
using high-speed standardized fiber interfaces.
Such low-latency fiber interfaces ensure good
synchronization across antennas and make the
transmission distributed antennas as a natural
extension of MIMO.-New deployments are needed to address the
