5G – Fifth Generation Mobile Phone systems
5G enables fast data speeds for critical applications.
It will also connect billions of Internet of Things (IoT)
devices. 5G Specifications include about 30 different
bandwidths, modulation types and speeds.
4G-LTE is about 500 times faster than 3G. 5G and
5G-NR are about twice as fast as 4-LTE. To start with
5G will only be used for video calls, streaming and
large downloads of data and for the next few years
4G-LTE will handle most calls.
Low-band (up to 2.5 GHz) offers the advantage of
wide-area coverage and the ability to penetrate
buildings so that devices can work reliably indoors.
Mid-band (2.5 to 5 GHz) offers greater capacity and
speed. It has a shorter range and is more easily
blocked by solid structures, so more base-stations
are needed. Massive MIMO (multiple carriers and
targeted beams) can start to be used.
High-band (24-29, 37-42, 64-71 GHz) will slowly be
rolled out from 2020. It offers extreme capacity and
speed and will need a different type of meter to
measure it. It only has a short range of typically a
few hundred meters at most. It will use MIMO,
which will create high-exposure hot-spots and will
need large numbers of small-cell access points close
to users. It is currently practical only for fixed links or
line of sight use. Indoor use will usually need a 5G
Access Point inside the room.
