RF exposure limit according to FCC CFR 47 parts 1 and 2 §1.310(e), §2.1091(b). According report 7212326080 of SII FCC ID: XBL-LEGTAG FCC §1.1310 limit of power density for general population/uncontrolled exposure is 1 mW/cm 2 . The EUT is defined as module inside portable device designed to be used so that the radiating structure(s) of the device may be used at 20 centimeters distance from the body of the user. Pt- the transmitted maximum EIRP power = -36.52 dBm = 0.00022291 mW. Peak power density for distance 20 cm is Pt/4πr² = 0.00022291 mW/4π*20² = 4.434*10 -8 mW/cm². That is less than 1 mW/cm² power density limit .

General description: * Note: the customer supplied all information in clause below. The Equipment Under Test (hereinafter: EUT) is a Cow Leg Tag Model RF Transmitter (V2.00) (intended) to be used in a farm shed and in the parlor. The tag is attached to a belt and worn around the leg of a cow. The main future of the Transceiver is to receive and transmit the cow tag data. A Cow tags used for Cow monitoring. The tag is counting steps and monitor cow behaviour. Tag works in the transmitting at 433.92MHz. Tag works with the battery a 3 Volt ( CR123A BATTERY ), Type of modulation: FSK Antenna type: Built-in internal antenna on the printed circuit board. Antenna gain 0 dBi. The EUT external view is presented in photo 1. Photo 1. Transceiver view and block diagram.
