Band Availability • Large amount of unlicensed spectrum

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

Using LTE Advanced Technology to Aggregate Licensed & Unlicensed Spectrum


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
