Power Requirements
Hardware Overview 21
Power Requirements
RF Power Output
The M6e supports separate read and write power level which are command adjustable
via the MercuryAPI. Power levels must be between:
– Minimum RF Power = +5 dBm
– Maximum RF Power = +31.5 dBm (+0.0/- 0.5 dB accuracy above +15 dBm)
Note
Maximum power may have to be reduced to meet regulatory limits, which
specify the combined effect of the module, antenna, cable and enclosure
shielding of the integrated product.
WARNING!
Operation requires professional installation to correctly set the TX
power for the RF cable and antenna selected.
Power Settings for Authorized Antennas and Cables
This device has been designed to operate with the antennas listed in Authorized Antennas
list using the cables in the Authorized Cables
list. For any combination of antenna and
cable the maximum RF power is determined from antenna gain (Max Linear Gain value
from antenna list) and antenna cable loss (Insertion Loss value from cable list) using the
formula:
Pmax = 36 dBm - Antenna Gain + Cable Loss
For example, for the Laird S8658WPL and the ThingMagic CBL-P6 6ft cable the following
calculation can be performed:
Max linear antenna gain = 6 dBiL
Minimum cable insertion loss = 0.8 dB
Pmax = 36 - 6 + 0.8 = 30.8 dBm
The maximum RF power that may be set using this configuration is 30.8 dBm (see
Warning above).
