There have been plenty of developments in
the field of mobile technologies in the past few years
that has ultimately led to the current technology of 5G.
It is being deployed by numerous telecommunication
companies around the world. There are a few places
where it is currently in use and under testing phase in
others. The evolution of wireless cellular technology
brought us faster data speeds and services. Many
challenges will be faced before 5G becomes a household
for every smartphone. With leading companies
launching 5G compatible phones and worldwide
recognition of this novel technology, it is important to
understand the challenges and future opportunities in
this domain. This paper has thrown light on the
evolution of wireless mobile technologies, the concept of
5G, its challenges, further development opportunities
and a proposed solution which can help overcome
drawbacks of 5G and make it available to the mass.
