Abstract
5G networks are envisioned to ease the burden on the current infrastructure by
offering significantly higher data rates through increased channel bandwidths.Presently,
all wireless technologies are operating in 300MHz to 3 GHz band. Due to the shortage of
available frequencies traditionally used for mobile communications, mm-wave bands is
an alternative. The key essence of 5G wireless networks lies in exploration of
high-frequency mmWave band ranging from 3 GHz to 300 GHz.
The large bandwidth available at these frequencies helps to offer data rates that
satisfy 5G demands. But the mobile environment at these mm-wave bands is far more
complex than at the currently used frequencies. Higher propagation losses that greatly
vary depending on the environment require an updated network infrastructure and
new hardware concepts. Beamforming antenna arrays will play an important role in 5G
implementations because even handsets can accommodate a larger number of antenna
elements at mm-wave frequencies. Apart from a higher directive gain, these antenna
types offer complex beamforming capabilities. Millimeter-wave bands potentially
enable high bandwidths. To limit the use of these high frequencies is a result of adverse
propagation effects in particular due to obstacles in the LoS.
