Transmitter Output Power
Nations and regions may regulate transmitter output power. For example
◦ Both 900-MHz and 5.7-GHz modules are available as connectorized radios,
which require the operator to adjust power to ensure regulatory compliance. In
addition to setting the power in the 5.7-GHz connectorized module, the operator
must set the antenna gain/cable loss such that the module can accurately report
received power at the antenna.
◦ Legal maximum allowable transmitter output power and EIRP (Equivalent
Isotropic Radiated Power) in the 2.4-GHz frequency band varies by country and
region. The output power of Series P9 2.4-GHz modules can be adjusted to meet
these national or regional regulatory requirements.
◦ Countries and regions that permit the use of the 5.4-GHz frequency band (CEPT
member states, for example), generally require equipment using the band to
have adjustable power.
The professional installer of Cyclone equipment has the responsibility to
• maintain awareness of applicable regulations.
• calculate the permissible transmitter output power for the module.
• confirm that the initial power setting is compliant with national or regional
regulations.
• confirm that the power setting is compliant following any reset of the module to
factory defaults.
For information on how to calculate the permissible transmitter output power to enter in
this parameter, see Adjusting Transmitter Output Power on Page 330.
The Radio tab also contains the following buttons.
Save Changes
When you click this button, any changes that you made on all tabs are recorded in flash
memory. However, these changes do not apply until the next reboot of the module.
Reboot
When you click this button
1. the module reboots.
