Today and in the recent future, to fulfill the presumptions
and challenges of the near future, the wireless based net-
works of today will have to advance in various ways. Recent
technology constituent like high-speed packet access (HSPA)
and long-term evolution (LTE) will be launched as a
segment of the advancement of current wireless based
technologies. Nevertheless, auxiliary components may also
constitute future new wireless based technologies, which
may adjunct the evolved technologies. Specimen of these
new technology components are different ways of accessing
spectrum and considerably higher frequency ranges, the
instigation of massive antenna configurations, direct device-
to-device communication, and ultra-dense deployments
