Operational Description

The Equipment Under Test (EUT) is a Beacon Transmitter which is placed inside a vehicle. The EUT broadcasts a Bluetooth BLE signal. The corresponding Metromile Apps program running in an IOS device (e.g. Apple iphone) uses this signal to know when the driver driving in the vehicle and records driving statistics and location data. The EUT can only support Bluetooth 4.0 BLE only. The Bluetooth portion occupies a frequency range of 2402MHz to 2480MHz (40 channels with channel spacing of 2MHz). The EUT is powered by a CR2032 3V Lithium battery. The main components are described below: 1. U1 (CC2541) is a System-On-Chip (SOC) solution incorporating with Bluetooth 4.0 BLE Compliant radio, 8051 MCU, 8k RAM, CODEC and other I/O peripherals. 2. B241 (LFB182G45BG2D280) is the balance matching band-pass filter for the 2.4GHz ISM band. 3. C242 and L243 are components of the antenna matching network. 4. X1 (32MHz crystal) provides system clock for U1 (CC2541). 5. X2 (32.768kHz crystal) provides a slow clock for reducing operating energy. 6. BC1 is CR2032 3.0V Lithium battery. 7. U2 (TPS62730) is DC/DC converter provides 3V regulated power supply. 8. PB1 is Tact switch for activating the EUT. 9. D1 is green LED indicator.

The EUT is powered by a CR2032 3V Lithium battery. Antenna Type: Internal integral antenna Antenna Gain: 0dBi Nominal rated field strength: 99.8dBμV/m at 3m Maximum allowed field strength of production tolerance: +/- 3dB According to the KDB 447498: Based on the Maximum allowed field strength of production tolerance was 102.8dBμV/m at 3m in frequency 2.4GHz, thus; The EIRP = [(FS*D) ^2*1000 / 30] = 5.716mW Conducted power = Radiated Power (EIRP) – Antenna Gain So; Conducted Power = 5.716mW. The SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (2.480) mW = 9.53 mW Since the above conducted output power is well below the SAR Exclusion threshold level, so the EUT is considered to comply with SAR requirement without testing.
