larger bandwidth allocations will come up with higher data
transfer rates and service providers that are presently using
20 MHz channels for 4G customers will now signicantly
expand the channel bandwidths [87]. With the increase in
bandwidth, capacity will also get increased, while the latency
will get decreased, which give rise to better internet based
access and applications like real time streaming. Since the
wavelength of millimeter wave frequencies are very small,
so it will utilize polarization and different spatial processing
techniques like massive MIMO and adaptive beamforming
[15]. With the signicant increase in bandwidth,
the data links to densely populated areas will now handle
greater capacity than present 4G networks. Likewise the base
stations are constantly reducing the coverage areas of the cell
for spatial reuse, cooperative MIMO, relays and interference
mitigation between base stations. Since the base stations are
abundant and more densely dispersed in urban areas, which
will reduce the cost per base station. Spectrum distributions
of over 1 GHz of bandwidth are currently being utilized in
the 28 GHz and 38 GHz bands.
