Open a historical report with a data traffic graph and change the years in the X axis. You will still see an exponentially-rising amount of data traffic! The question is…How do we support this traffic demand without breaking the bank? One of the low-cost mechanisms is getting access to more spectrum. Since the amount of licensed spectrum is limited, we can explore unlicensed spectrum. This chapter discusses how LAA and eLAA can be deployed in unlicensed spectrum to quickly and cost-effectively increase throughput.
