RF Exposure Info

RF EXPOSURE EVALUATION According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency(RF) Radiation as specified in KDB 447498 D01 V06 and §1.1307(b) CFR Title 47 §2.1091(b): (b) For purposes of this section, a mobile device is defined as a transmitting device designed to be used in other than fixed locations and to generally be used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter’s radiating structure(s) and the body of the user or nearby persons. FCC ID: 2BTEU-B26-4 EUT Specification EUT Tachograph Frequency band (Operating) WLAN: 2.412GHz ~ 2.462GHz WLAN: 5.18GHz ~ 5.24GHz WLAN: 5.745GHz ~ 5.825GHz Others: 2.402GHz~2.480GHz BT NFC: 13.56MHz RFID: 125kHz Device category Portable (<20cm separation) Mobile (>20cm separation) Others ___ Exposure classification Occupational/Controlled exposure (S = 5mW/cm2) General Population/Uncontrolled exposure (S=1mW/cm2) Antenna diversity Single antenna Multiple antennas Tx diversity Rx diversity Tx/Rx diversity Evaluation applied MPE Evaluation SAR Evaluation Limits for Maximum Permissible Exposure(MPE) Note: Emissions between 100 kHz to 300 kHz should be assessed versus the limits at 300 kHz in Table 1 of Section 1.1310: 614 V/m and 1.63 A/m.AKDB inquiry is required to determine the applicable exposure limits below 100 kHz. Friis transmission formula: Pd=(Pout*G)\(4*pi*R2) Where Pd= Power density in mW/cm 2 Pout=output power to antenna in Mw G= gain of antenna in linear scale Pi=3.1416 R= distance between observation point and center of the radiator in cm Pd the limit of MPE, 1mW/cm2. If we know the maximum gain of the antenna and total power input to the antenna, through the calculation, we will know the distance where the MPE limit is reached.

Efficiency and Gain ◼ 量测仪器: 微波暗室，Agilent网络分析仪，Agilent频谱分析仪，8960综合测试仪，标准天线。 ◼ 微波暗室说明: 这是本公司设置在深圳的微波暗室，本微波暗室是属于一套远场量测系统,暗室的大小为5.0米 x3.0米x3.0米，静区尺寸(Quiet zone)大小为15厘米x15厘米x15厘米。图. 1 为微波暗室内的仪器设置及网络分析仪的联接图，发射天线(0.8-6.0GHZ for Gain Calibration) 到待测天线(AUT)的距离为3.0米，待测天线放置在旋转平台上,藉由控制转台旋转的角度可对待测天线做概略性及较为准确的量测。将待测天线放置于旋转台上,并测得其各个平面(ZY平面及ZX平面)的360度场强数据。再将待测天线换置成标准偶极天线将其360度的场强数据测出，以作换算增益标准值，经由式1的换算即可获得待测天线的增益值及方向图。 3-1 Measuring Method 1. Using a low loss coaxial cable to link a standard handset jig, 2. Fixed this handset jig on chamber’s rotator plane, 3. Linking jig into network analyzer port and using a probing horn antenna to collect data, 4. Using another standard gain horn antenna to calibrated those data.
