5 License assisted Access (LAA) Applying LTE-A Benefits to Unlicensed Spectrum LAA LTE Consumer, Business, Enterprise and Industrial Users Aggregation of LTE on Licensed & Unlicensed Spectrum Wi-Fi Residential, Enterprise Licensed Spectrum Wireless Network Demand Supply of Unused Spectrum Unlicensed Spectrum Ericsson License Assisted Access LAA Ericsson AB 2015 January 2015 Page 5

6 LAA Unlocks 5 GHz spectrum for LTE LTE licensed spectrum for performance Using LTE Advanced Technology to Aggregate Licensed & Unlicensed Spectrum PLUS LTE unlicensed spectrum for speed boost Speed boost to carry additional data payload Using only 4 percent of the 5 GHz band, LAA can provide up to a 150 Mbps speed increase LTE efficiencies applied to unlicensed spectrum LTE Macro Performance LTE Primary Carrier Licensed Spectrum LAA Unlicensed 1+ Gbps LTE Small Cells improved performance LTE Secondary Carrier Unlicensed Spectrum Ericsson License Assisted Access LAA Ericsson AB 2015 January 2015 Page 6

7 Sharing 5 GHz spectrum fairly LTE Wi-Fi Coexistence Sharing Goal LAA not to impact Wi-Fi services more than an additional Wi-Fi network on the same carrier 2-step approach On start up, choose least busy carrier LTE Wi-Fi Share channel access time fairly with Wi-Fi, conforming to regulations in various regions Fair Sharing 3GPP studying coexistence options Ericsson License Assisted Access LAA Ericsson AB 2015 January 2015 Page 7
