NEC and Ubidyne Verify the Benefits of 3D Beamforming for Small

NEC and Ubidyne Verify the Benefits of 3D Beamforming for Small Cells 
Joint white paper looks at enhanced network capacity and coverage with active
small cell antennas 
Tokyo, Feb 13, 2013 - (JCN Newswire) -  NEC and Ubidyne have joined forces to
investigate the benefits of 3D beamforming small cells with the use of the
latest active antenna technology. The study, entitled 'Enhanced Network
Capacity and Coverage with 3D Beamforming Small Cells', benchmarks passive
small cells with active beamforming small cells that look set to be an integral
part of future LTE / 4G heterogeneous networks (HetNets) to meet the
dramatically increasing demand for capacity. 
The study explores the advantages of a new class of small cell - the array or
3D beamforming small cell - and shows that 3D beamforming can lead to an
average macro cell load reduction (offloading) of 40%. An active 3D beam
forming small cell comprises several antenna elements and transceivers arranged
in a matrix which enables completely flexible vertical and horizontal
beamforming, including beam shaping independent in the downlink (DL) and uplink
(UL). Furthermore, multiple simultaneous beams per cell with individual tilt
optimization per beam, as well as multiple beams for multi-sector operation can
be applied. 
The investigations show that 3D beamforming and individual tilt optimization
for multi-beam active small cell antenna arrays outperforms existing passive
small cell solutions, with about four-times higher offloading. In addition to
capacity gains, beamforming can also help to improve coverage, reduce the
number of small cells and backhauling requirements and reduce inter-cell
interference. This cuts the cost of site acquisition and network-wide power
consumption and further improves network optimization, making active antennas
an attractive proposition for mobile operators.
