2.2 Guidelines for Limiting RF Exposure
The Core Engine products are GSM radio transceivers.
The following installation and operation restrictions apply to the all Core Engine products:
!
A separation distance of at least 20 cm (7 7/8) inches between the antenna and body of
the user and other persons must be maintained at all times
the user and other persons must be maintained at all times
!
In FIXED applications using a 1900Mhz Core Engine antenna gain* is limited to a
maximum of 7 dBi, with a corresponding equivalent isotropic radiated power (EIRP) of 37
dBm / 5 W
maximum of 7 dBi, with a corresponding equivalent isotropic radiated power (EIRP) of 37
dBm / 5 W
!
In MOBILE applications using a 1900Mhz Core Engine antenna gain* is limited to a
maximum of 3 dBi, with a corresponding equivalent isotropic radiated power (EIRP) of 33
dBm / 3 W
maximum of 3 dBi, with a corresponding equivalent isotropic radiated power (EIRP) of 33
dBm / 3 W

Desktop and other uses of these devices where the antenna can easily be relocated are
considered by the FCC to be mobile applications.
considered by the FCC to be mobile applications.
* Antenna gain is defined as gain in dBi (dB referenced to an isotropic radiator) minus cabling loss.
NOTE: Additional care must be taken by the installer and/or user of the Core Engine
products to ensure proper antenna selection and installation. Adherence to the
above conditions is necessary to comply with FCC requirements for safe operation
regarding exposure to RF radiation.
