Qualcomm and SK Telecom Announce First Enhanced Licensed Assisted Access (eLAA) Over-the-Air Trial

SAN DIEGO, Sept. 28, 2016 /PRNewswire/ -- Qualcomm Incorporated (NASDAQ: QCOM) today announced that its subsidiary, Qualcomm Technologies, Inc. (QTI), and SK Telecom (CEO Dong-hyun Jang, www.sktelecom.com) announced the first over-the-air technology demonstration of eLAA (Enhanced Licensed Assisted Access) and LAA (Licensed Assisted Access) that utilizes both licensed and unlicensed spectrum at SK Telecom's Corporate R&D Center in Bundang, Korea.

eLAA technology increases data speeds in both uplink and downlink by aggregating licensed and unlicensed spectrum to create a wider data pipe in both directions. eLAA is an evolution of LAA, which used the unlicensed spectrum to boost the data speed in the downlink direction only.

The demo uses 2.6GHz licensed spectrum and 5GHz unlicensed spectrum. When evaluating coexistence, a baseline was first established using only Wi-Fi users, of which some were then switched from Wi-Fi to LAA/eLAA while others remained on Wi-Fi. The trial demonstrated that the users that remained on Wi-Fi were unaffected by those that switched to LAA/eLAA. This effectively demonstrates that LAA/eLAA shares the unlicensed spectrum fairly with Wi-Fi. The sharing mechanism used by LAA/eLAA is called listen-before-talk (LBT). As for performance, LAA and eLAA were shown in multiple test cases to achieve 2X capacity in 5 GHz than the Wi-Fi only baseline.

In June 2015, SK Telecom launched "Band LTE Wi-Fi"...
