Description
The fifth generation (5G) wireless network systems is also known as
worldwide wireless web (W4) because based on laid-out expectations, it does
not require limitations. Though 5G is not fully deployed at present, one major
technology that will contribute immensely to its reality is massive MIMO. There
are, however challenges associated with it which serve as goldmines for
future work. This review is aimed at gaining understanding of the laid-out
specifications of 5G networks, the operation of massive MIMO as a
technology for 5G and the challenges to be addressed by future work to
enable the effective deployment of the technology to future generation
networks. Various searches in science direct, Google scholar and IEEE
Xplore are carried out to obtain all relevant studies. Papers that were
considered range from the years 2010 through 2017 to ensure that current
information is retrieved. From initial search processes, a total of about 500
papers that were related to the subject matter were retrieved. Out of about 70
filtered studies from the total obtained, 15 were selected after detailed
analysis. This review will help to enhance further research works in massive
MIMO technology as it exposes the associated limitations as well as some of
the related areas being subjected to current research and investigation.
