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
Wi-Fi
LTE
• 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
