US Draft Report & Order Outcome

• Indoor low power across the entire band without AFC @ 5 dBm/MHz; Prohibition on connectors
• Automated Frequency Coordination (AFC) required in UNII-5/7 for “full” power indoor and all outdoor APs
• FNPRM on “Very Low Power” class for portable APs and short-range applications
