Information connectivity continues to evolve, as does wireless technology. The first wave of information connectivity disruption happened decades ago in
our homes and businesses through wired telephony
and the early Internet via dial-up modems. Since then,
the development of communication networks has been
superseded by wireless mobile technology connecting
people instead of places. Today, there are over seven
billion mobile devices in the world connecting over 3. 8
billion people. The next era will connect things. It has
been well published that within the next decade we
expect to connect at least 10 times the number of things
as people, representing another sea of change.
This next era, the so called Internet of Things (Io T) or
even the Industrial Internet of Things (IIo T), will drive
the development of new wireless technologies supporting
the underlying infrastructure defined in 5G network
standards currently being conceptualized. The promise
of increased information bandwidth and faster response
times (low latency) for real-time wireless control, all with
minimal power consumption, makes for highly attractive
yet very challenging system performance goals. While the
technical requirements necessary to make 5G and the Io T
a commercial success are very demanding, the economic
potential and business opportunities are enormous.
5G networks will likely be based on multi-radio access
technology (Multi-RAT) using existing cellular base
stations to ensure broad coverage and high-mobility and
interspersed small cells for capacity and indoor service.
These future networks use a combination of small cell +
macrocell base stations, as well as cellular + Wifi with
considerable research into using Wifi for cellular traffic
offloading. Although there is not yet full agreement
on which technology will address the 5G challenge,
