VAT No. 475 2328 39 Web: www.RNElectronics.com Email: [email protected] 6870 module (EUT) RF Exposure:- The 6870 module is intendedas a mobile device. Instructions to host manufacturer included in the installation manual relate to mobile use and 200mm (0.2metres) distance and the relevant RF exposure requirements. The module device has three transmitters in it, a ZigBee device with two antennas and two UWB devices with an antenna each. The UWB devices cannot transmit with each other, either one of the UWB devices can transmit at the same time as the ZigBee radio. The ZigBee radio transmits out of one of its antennas only at a time. This evaluation covers the three transmitters operating individually and either of the UWB transmitters operating with the ZigBee transmitter simultaneously. RF exposure test exemption/calculation is demonstrated using: KDB 447498 D04 Interim General RF exposure Guidance. Clause 2.1 RF exposure Test Exemptions for single source Clause2.1.4MPE-Based Exemption An alternative to the SAR-based exemption is provided in § 1.1307(b)(3)(i)(C), for a much wider frequency range, from 300 kHz to 100 GHz, applicable for separation distances greater or equal to λ/2π, where λ is the free-space operating wavelength in meters. The MPE-based test exemption condition is in terms of ERP, defined as the product of the maximum antenna gain and the delivered maximum time-averaged power.10 For this case, a RF source is an RF exempt device if its ERP (watts) is no more than a frequency-dependent value, as detailed tabular form in Appendix B. These limits have been derived based on the basic specifications on Maximum Permissible Exposure (MPE) considered for the FCC rules in § 1.1310(e)(1). Clause2.2RF Exposure Test Exemptions for Simultaneous Transmission Sources Clause 2.2.2Simultaneous Transmission with both SAR-based and MPE-Based Test Exemptions This case is described in detail in § 1.1307(b)(3)(ii)(B) and covers the situations where both SAR-based and MPE-based exemption may be considered for test exemption in fixed, mobile, or portable device exposure conditions. For these cases, a device with multiple RF sources transmitting simultaneously will be considered an RF exempt device if the condition of Formula (1) is satisfied. For these test exemptions to apply, the maximum output power, duty factor, and other applicable parameters used in the standalone ERP determination tests, must be the same, or corresponding to a more conservative choice, than those required for simultaneous transmission. The power level of the standalone SAR used to qualify for SAR test exemption, or additional test exemption, must be clearly explained in the SAR report. When simultaneous transmission SAR-based test exemptions, or when the SPLSR test exemption [Section 2.2.3] cannot be applied, enlarged zoom scan [Glossary] SAR measurements must be performed at the maximum output power required for the applicable simultaneous transmission scenarios. This power level shall account for the tune-up tolerance [Glossary] requirements of all transmitters, but not more than 2 dB lower than the maximum tune-up tolerance limit.

The antenna has sufficient gain at the band edges to satisfy the applications and uses a high dielectric constant ceramic giving it some detuning resilience to capacitivel loading effects. This antenna is designed for close proximity applications such as the ones mentioned on page 1. 2.4 GHz SMD, Above Metal, L…
