3. 3 For transmitters that employ frequency hopping stepped frequency or similar modulation types the peak emission level measurement the measurement of the RMS average emission levels and the measurement to determine the frequency at which the highest level emission occurs shall be made with the frequency hop or step function active Gated signals may be measured with the gating active The provisions of 15 31 c continue to apply to transmitters that employ swept frequency modulation 4 The 10 dB bandwidth is based on measurement using a peak detector a 1 MHz resolution bandwidth and a video bandwidth greater than or equal to the resolution bandwidth 5 Alternative measurement procedures may be considered by the Commission 14 3 Part 15 505 Cross Reference a Except where specifically stated otherwise within this subpart the provisions of subparts A and B and of 15 201 through 15 204 and 15 207 of subpart C of this part apply to unlicensed UWB intentional radiators The provisions of 15 35 c and 15 205 do not apply to devices operated under this subpart The provisions of Footnote US 246 to the Table of Frequency Allocations contained in 2 106 of this chapter does not apply to devices operated under this subpart b The requirements of this subpart apply only to the radio transmitter i e the intentional radiator contained in the UWB device Other aspects of the operation of a UWB device may be subject to r
4. Operation under the provisions of this section is limited to UWB transmitters employed solely for indoor operation Indoor UWB devices by the nature of their design must be capable of operation only indoors The necessity to operate with a fixed indoor infrastructure e g a transmitter that must be connected to the AC power lines may be considered sufficient to demonstrate this The emissions from equipment operated under this section shall not be intentionally directed outside of the building in which the equipment is located such as through a window or a doorway to perform an outside function such as the detection of persons about to enter a building The use of outdoor mounted antennas e g antennas mounted on the outside of a building or on a telephone pole or any other outdoors infrastructure is prohibited Field disturbance sensors installed inside of metal or underground storage tanks are considered to operate indoors provided the emissions are directed towards the ground A communications system shall transmit only when the intentional radiator is sending information to an associated receiver The UWB bandwidth of a UWB system operating under the provisions of this section must be contained between 3 100 MHz and 10 600 MHz The radiated emissions at or below 960 MHz from a device operating under the provisions of this section shall not exceed the emission levels in 15 209 The radiated emissions above 960 MHz from a de

6. The UWB bandwidth of a device operating under the provisions of this section must be contained between 3 100 MHz and 10 600 MHz so any of the DW1000 channels is permitted 4 3 4 Specific wording of the application Generally speaking the FCC is supportive of UWB technology applications and products and will not seek to intentionally block the certification of such products provided that compliance with the relevant regulations can be established The way an application is phrased constructed can have an impact here It is important to understand the intention behind the FCC s use of certain words and to avoid those words in your application where possible Word Phrase in the Code of Federal Comment regulations The FCC does not permit any device certified under 15 5xx to operate on board an aircraft This has a number of implications e Products intended for use on board aircraft should not use UWB technology Aircraft e You must ensure if your product is being transported by air that the UWB transmitter is not enabled e If there is any question over whether your application involves an aircraft then you should phrase it such that the word aircraft does not appear in the application The term fixed is generally used by the FCC in the context of outdoor installations The FCC s thinking in this regard is that if there are fixed installations radiating UWB signals close to particular facilities
7. actual measurements 3 2 2 Intended emissions tests For intended emissions tests the applicable regulations specify the maximum allowed radiated power level from the DUT over the frequency range of interest For UWB devices this spans from 0 GHz to in excess of 10 5 GHz These emission limits vary across regulatory jurisdictions They also vary for particular applications DecaWave 2015 This document is confidential and contains information which is proprietary to DecaWave Limited No reproduction is permitted without prior express written permission of the Page 9 of 39 author How to take your DecaWave UWB based product through the d W certification process in the USA ecawave and use cases so it is important to agree with the accredited test house for which use cases your product is being certified The measurement instrument generally a spectrum analyser is set up for the frequency span of interest various other parameters are appropriately set and the DUT is configured to transmit at the maximum intended power level generally 41 3 dBm MHz in UWB applications It is desirable to configure the DUT into back to back repeated frame mode because this allows the spectrum analyser capture the transmitted spectrum more quickly but if this is not possible the DUT should be configured for the faster transmission repetition rate possible The test starts by measuring the radiated spectrum from the DUT with the DUT and the antenna in
