13.2. Electromagnetic Compatibility (EMC) and Safety Requirements The Enfora Enabler IIIG module has been tested and approved for application in the United States of America (US) and the European Union (EU). The compliance details for each of these markets follow. For other markets, additional or alternative regulatory approvals may be required. Always ensure that all rules and regulations are complied with in every country that the OEM application is to be operated.
Regulations, including those that implement the National Environmental Policy Act of 1969 (Part 1, Subpart I), with specific regard to antenna sitting and human exposure to radio frequency radiation. For further guidance, consult the FCC Rules, a certified FCC test house, or Enfora. 13.5.
Equipment designated as Class A is intended for use in a commercial, industrial or business environment. The Enfora Enabler IIIG module has been tested and found to comply with the limits for a Class A digital device and can be integrated into equipment or applications intended for use in commercial, industrial or business environments.
Both of these documents are available via the Internet at the OET web site: http://www.fcc.gov/oet The Enfora Enabler IIIG products are GSM radio transceivers, which operate under the authority of 47 CFR Part 24, Subpart E and Part 22 of the FCC Rules and Regulations. When installed and operated in accordance with the instructions provided in this manual, these devices comply with current FCC regulations regarding human exposure to radio frequency radiation.
Page 83
Enfora Enabler IIIG M2M Modem Integration Guide Note: Additional care must be taken by the installer and/or user of the Enfora Enabler IIIG 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.
For fixed applications (2 meter separation) the antenna gain can be as much as 26 dBi. radiation Modifications and/or additions to the Enfora Enabler IIIG GSM transceiver, including use of antennas with higher gain than those authorized by the FCC, are prohibited...
Current FCC regulations limit the EIRP of mobile devices to 2 W. Because the nominal RF output power of the Enfora Enabler IIIG GSM1900 GSM transceiver is 1.0 W (31 dBm), antenna gain for mobile products and applications cannot exceed 2 dBi.
In most other countries that have not been listed above there are similar rules and regulations that must be met for importing the Enfora Enabler IIIG module. Each may require a different mark of approval (for example, the CB Scheme) as an acceptance requirement. For each of these cases the country should identified, and the appropriate steps should be taken to meet the requirements set forth in the intended market.
Application Programming Interface. App Application Refers to the Application which sends or receives commands/responses from the Enfora Enabler IIIG Module AT Command Set Commands issued by intelligent device to a modem to perform functions, such as to initiate call, to answer call, or to transmit data.
