The reference sensitivity performance in terms of frame erasure, bit error, or residual bit error rates (whichever is approproate)
is specified in the following table, according to the propagation conditions.
Channels
Propogation Conditions
TUhigh
Propogation Conditions
RA
Propogation Conditions
HT
Static Conditions
Note: 1 <
α
< 1.6. The value of
α
can be different for each channel condition but must remain the same for
FER and Class 1b RBER measurements for the same channel condition.
The reference sensitivity level is < –102 dBm.
