After all, it takes time to take action for it In case of planogram issues such as out of stock and misplacement product, both customers and staff can search and find the product on their mobile device(which shows where it is located on) thanks to the tag assigned to the product. Therefore, customers don’t need to ask the assistance and staff can replenish products, and replace items to the right place SNACK NONFOOD SECIALS SHELVING NONFOOD SECIALS SNACK SHELVING RRODUCT RRODUCT SHELVING found it!

The MPE calculation for this exposure is shown below. The peak radiated output power (EIRP) is calculated as follows: EIRP = P + G Where, P = Power input to the antenna (mW) G = Power gain of the antenna (dBi) The numeric gain(G) of the antenna with a gain specified in dB is determined by: G = Log -1 (dB antenna gain / 10) Power density at the specific separation: S = PG/(4R 2 π) Where, S = Maximum power density (mW/cm 2 ) P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20 cm = limit for MPE) Estimated safe separation: R = √(PG / 4π) Where, P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20 cm = limit for MPE) CTK Co., Ltd.

After the trace being stable, Use the marker-to-peak function to measure 20 dB down both sides of the intentional emission. Test Settings: Center frequency = the highest, middle and the lowest channels a) RBW = 100 kHz b) VBW ≥ 3 x RBW c) Detector = peak d) Sweep time = auto couple e) Trace mode= max hold f) Allow trace to fully stabilize g) Use the peak marker function to determine the maximum amplitude level. Limit : Emission level < 20 dBc Test Data: Complies - All conducted emission in any 100 kHz bandwidth outside of the spread spectrum band was at least 20 dB lower than the highest inband spectral density. Therefore the applying equipment meets the requirement. See next pages for actual measured spectrum plots. CTK Co., Ltd.

The Test Antenna is positioned with its plane vertical at 1m distance from the EUT. The center of the Loop Test Antenna is 1m above the ground. During the measurement the Loop Test Antenna rotates about its vertical axis for maximum response at each azimuth about th…
