Hi Andrew Grant notes, while some being generic, are always applicable to the particular grant on which they occur. In this case the source of the note is the device itself. The limit to gain is most likely due to the MPE caused by the gains listed being able to meet the separation distance specified in the MPE report. The grant for this particular device is only effective under those conditions. They deal with the device being used in a mobile rf configuration as well as the instances when they are fixed. The grant note is basically saying that you cannot use a higher gain antenna than listed unless MPE has been accounted for in either a PC2 or new ID application.

After a quick look on the FCC's search page at https://fjallfoss.fcc.gov/oetcf/eas/reports/GenericSearch.cfm I am guessing that the module you are looking at is from Multi-Tech Systems, FCC ID AU792U07G30822. I think others have replied with explanations as to the reasoning behind the requirement. Regards Mark At 02:00 AM 9/12/2008, Andrew McCallum wrote: Been given the note below but need to find the original source for reference can anyone help please? FCC Requirements Note: The antenna gain, including cable loss, must not exceed 3.0 dBi at 1900 MHz / 1.6 dBi at 850 M0Hz for mobile operating configurations and 7.0 dBi at 1900 MHz / 2.3 dBi at 850 MHz for fixed mounted operations, as defined in 2.1091 and 1.1307 of the rules for satisfying RF exposure compliance.
