5G planning aims at higher capacity than current 4G, allowing a
higher density of mobile broadband users,
and supporting device-to-device, ultra reliable, and massive machine
communications.
5G research and development also aims at lower latency than 4G
equipment and lower battery consumption, for better implementation of the Internet of things
There is currently no standard for 5G deployments.
The Next Generation Mobile Networks Alliance defines
the following requirements that a 5G standard should fulfil
If 5G appears and reflects these prognoses,
then the major difference, from a user point of view, between 4G and 5G must be
something other than faster speed (increased peak bit rate). For example,
higher number of simultaneously connected devices, higher system spectral efficiency (data volume per area unit), lower battery consumption,
lower outage probability (better coverage), high bit rates in larger portions
of the coverage area, lower latencies, higher number of supported devices,
lower infrastructure deployment costs, higher versatility and scalability, or
higher reliability of communication. Those are the objectives in several of the
research papers and projects below.
