LTE IN UNLICENSED BANDS: A RIVAL OR COLLABORATOR TO WI-FI?
Due to the rapidly increasing demand for internet traffic, mobile operators
have faced a problem of bandwidth availability. Since only licensed spectrum has
been previously utilized by wireless networks, moving LTE to the 5 GHz
unlicensed bands has become a popular research initiative, known as LTELicensed
Assisted Access (LTE-LAA).
This thesis studies the feasibility and implementation of LTE-LAA, and
sets a goal of confirming the effectiveness of this technology. An alternative
implementation of a Listen-Before-Talk channel contention mechanism is tested
in this work with the use of LTE-A Vienna Link Level Simulator. The obtained
results suggest that LTE-LAA is capable of boosting network throughput while
providing harmonious coexistence with the IEEE 802.11 standard operating in
the same unlicensed spectrum
