available in 5 GHz band
Regulatory Activity • Extensive collection of global regulations
within 3GPP RP-140054
• Mid 5 GHz radar detection in most regions
• Japan has a 4ms max transmission duration and listen before talk (LBT)
• Europe has LBT, max transmission duration & transmission BW requirements

LTE licensed spectrum for performance
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
LAA Unlocks 5 GHz spectrum for LTE
LTE Small Cells improved performance
LAA Unlicensed 1+ Gbps

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
• Share channel access time fairly with Wi-Fi, conforming to regulations in various regions
• 3GPP studying coexistence options
Sharing 5 GHz spectrum fairly LTE Wi-Fi Coexistence
