4.17.2.2 Least Interfered Channel (LIC) Selection, FCC Rule 15.323(c)(5):
The criteria are specified in section 4.17.2. In addition, the power measurement resolution
for this comparison must be accurate to within 6 dB.
Measurements are made in accordance with ANSI C63.17 sub-clause 7.3.3. Test setup is
shown in section 3.3 Figure 3.3.1. RF signal generators apply uniform CW interference on
all EUT carriers except two carriers (designated f
1
and f
2
), each at level T
U
+ U
M.
EUT can
only transmit on these two carriers.
