Long-Term Evolution (LTE), the most sought after
next-generation (4G) super-fast wireless communications
technology, is rapidly gaining momentum globally. The 4G wireless
network aims to cope with substantial demand for high-speed
wireless data services and mobile video.
The Global Mobile Suppliers Association (GSA) recently
reported that currently 268 LTE networks are commercially
available in 100 countries. The GSA estimated that more than 350
LTE networks will be commercially functional by the end of
In Nov 2013, The GSM Association's research wing, GMSA
Intelligence, forecasted that there will be more than 1 billion
LTE connections globally by 2017. Also, around 465 live LTE
networks are projected to be present across 128 countries by
GSMA Intelligence further reported that LTE users consume an
average of 1.5GB data per month, two-fold the amount consumed by
non-LTE users. In developing countries, LTE users are likely to
generate 20 times higher average revenue per user (ARPU) for
carriers than non-LTE users, whereas in developed countries ARPU
can be 10%-40% higher for LTE users than non-LTE users.
LTE offers several advantages over legacy 3G network
technologies. This includes improved spectral efficiency, lower
costs, and solid integration with other open wireless standards.
Theoretically, LTE is expected to achieve download transmission
speeds up to 300Mbps and upload transmission speeds up to 100
LTE also supports flexible carrier bandwidth and both FDD
(frequency division duplexing) and TDD (time division duplexing)
on the same platform. Ability to phenomenally enhance speed and
capacity are the positives which spur LTE adoption by wireless
