Section 3: Equipment under test (EUT) details 3.4 Product description and theory of operation The RBT-002 Locator Tent is a Bluetooth SmartTM equipped location tracking token for use by major quick service and fast casual restaurants to provide on- time, table-level accurate meal delivery services. As a component of the Radius Networks in-venue location tracking system, individual locator tents can be tracked as they are moved within store, restaurant or other physical venue. The functional purpose of the RBT-002 Locator Tent is to transmit a message, in the form of a Bluetooth Smart non-connectable advertisement, containing a unique identifier to an array of receivers that are distributed throughout a venue such as a store or restaurant. As a user carrying an RBT-002 Locator Tent moves throughout the venue. The transmitted messages that are received by the receiver array are analyzed by a central processor to determine the user’s location in the venue. Each RBT-002 is equipped with dual Bluetooth Smart transmitters for redundancy and load sharing. Each transmitter will be operating at a minimum transmission interval of 250ms with a transmit time of 300us for each transmitted message. The resulting combined duty cycle for both transmitters is 0.72%. The RBT-002 Locator Tent is powered by two CR-2032 lithium coin cell batteries, providing over 12 months of continuous service without the need for recharging or battery replacement. As part of an on-going service arrangement, tents are generally replaced on an annual basis. None of internal components or batteries of the Locator Tent are intended to be user serviceable. Operational properties of the dual Bluetooth Smart transmitters, including transmission frequencies and power levels, are fixed at the factory and are not modifiable by the end customer. 3.5 EUT exercise details A test version of firmware was implemented that allows different RF channels to be in different EUT. EUT is set to fixed channel test mode with modulation and 100% duty cycle. As only the 3 advertising channels are used, only 2402/2426/2480MHz are selected. 3.6 EUT setup diagram Setup Ph oto i n s epa rate ex hi bi t fo r co nfi den ti al i ty reaso n Figure 3.6-1: Radiated Emissions Test Setup – below 1GHz Setup Ph oto i n s epa rate ex hi bi t fo r co nfi den ti al i ty reaso n Figure 3.6-2: Radiated Emissions Test Setup – above 1GHz 3.7 EUT sub assemblies Table 3.7-1: EUT sub assemblies Description Brand name Model/Part number Serial number EUT Case / Module Holder Radius Network RBT-002 N/A Modules with antenna EM Microelectronic EMBC01 N/a Modules with temporary RF connector EM Microelectronic EMBC01 N/a Report reference ID: FCC-15.247 and RSS-247 Radius RBT-002 BTLE #320139 Page 8 of 32

Section 8 Testing data Test name FCC 15.247(b) and RSS-247 5.4 (4) Transmitter output power and e.i.r.p. requirements Specification FCC Part 15 Subpart C and RSS-247, Issue 1 8.2 FCC 15.247(b) and RSS-247 5.4 (4) Transmitter output power and e.i.r.p. requirements 8.2.1 Definitions and limits FCC: (b) The maximum peak conducted output power of the intentional radiator shall not exceed the following: (3) For systems using digital modulation in the 902-928 MHz, 2400-2483.5 MHz, and 5725-5850 MHz bands: 1 Watt. As an alternative to a peak power measurement, compliance with the one Watt limit can be based on a measurement of the maximum conducted output power. Maximum Conducted Output Power is defined as the total transmit power delivered to all antennas and antenna elements averaged across all symbols in the signaling alphabet when the transmitter is operating at its maximum power control level. Power must be summed across all antennas and antenna elements. The average must not include any time intervals during which the transmitter is off or is transmitting at a reduced power level. If multiple modes of operation are possible (e.g., alternative modulation methods), the maximum conducted output power is the highest total transmit power occurring in any mode. (4) The conducted output power limit specified in paragraph (b) of this section is based on the use of antennas with directional gains that do not exceed 6 dBi. Except as shown in paragraph (c) of this section, if transmitting antennas of directional gain greater than 6 dBi are used, the conducted output power from the intentional radiator shall be reduced below the stated values in paragraphs (b)(1), (b)(2), and (b)(3) of this section, as appropriate, by the amount in dB that the directional gain of the antenna exceeds 6 dBi. IC: 5.4 Transmitter Output Power and Equivalent Isotropically Radiated Power (E.I.R.P.) Requirements (4) For DTSs employing digital modulation techniques operating in the bands 902-928 MHz and 2400-2483.5 MHz, the maximum peak conducted output power shall not exceed 1W. Except as provided in Section 5.4(5), the e.i.r.p. shall not exceed 4 W. As an alternative to a peak power measurement, compliance can be based on a measurement of the maximum conducted output power. The maximum conducted output power is the total transmit power delivered to all antennas and antenna elements, averaged across all symbols in the signalling alphabet when the transmitter is operating at its maximum power control level. Power must be summed across all antennas and antenna elements. The average must not include any time intervals during which the transmitter is off or transmitting at a reduced power level. If multiple modes of operation are implemented, the maximum conducted output power is the highest total transmit power occurring in any mode. 8.2.2 Test summary Test date December 12, 2016 Temperature 22 °C Test engineer Feng You Air pressure 1009 mbar Verdict Pass Relative humidity 59 % Report reference ID: FCC-15.247 and RSS-247 Radius RBT-002 BTLE #320139 Page 15 of 32

If the transmitter complies with the conducted power limits based on the use of RMS averaging over a time interval, as permitted under paragraph (b)(3) of this section, the attenuation required under this paragraph shall be 30 dB instead of 20 dB. Attenuation below the general limits specified in §15.209(a) is not required. In addition, radiated emissions which fall in the restricted bands, as defined in §15.205(a), must also comply with the radiated emission limits specified in §15.209(a) (see §15.205(c)). IC: In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated device is operating, the RF power that is produced shall be at least 20 dB below that in the 100 kHz bandwidth within the band that contains the highest level of the desired power, based on either an RF conducted or a radiated measurement, provided that the transmitter demonstrates compliance with the peak conducted power limits. If the transmitter complies with the conducted power limits based on the use of root-mean-square averaging over a time interval, as permitted under Section 5.4(4), the attenuation required shall be 30 dB instead of 20 dB. Attenuation below the general field strength limits specified in RSS-Gen is not required.
