Limit Values for Average Burst Power (Power Configuration – Limits)
The
Limits
tab defines tolerance limits for the average burst power depending on the power control
level of the mobile phone
(PCL)
. The limits apply to all applications of the
Power
menu providing a limit
check (not to
P/Frame, P/Slot Graph
and
P/Slot Table)
.
GSM mobile phones are divided into different power classes according to their maximum output power:

Besides, a dimensionless scale of power control levels
(PCL)
is determined for dynamic control of the
mobile power:

Besides, tolerance values are specified for all output powers under various conditions. Power control
permits to force the mobile power below the maximum value corresponding to its power class.
