4. FCC and IC Exemption Limits for Routine Evaluation
4.1. FCC SAR test exclusions per KDB 447498
KDB 447498 D01 General RF Exposure Guidance v06 Section: 4.3.1.
Standalone SAR test exclusion considerations states
a) For 100 MHz to 6 GHz and test separation distances 50 mm, the 1-g and 10-g SAR test
exclusion thresholds are determined by the following:
[(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] · [√f(GHz)]
≤ 3.0 for 1-g SAR, and ≤ 7.5 for 10-g extremity SAR,30 where
f(GHz) is the RF channel transmit frequency in GHz
Power and distance are rounded to the nearest mW and mm before calculation
The result is rounded to one decimal place for comparison
The values 3.0 and 7.5 are referred to as numeric thresholds.
The test exclusions are applicable only when the minimum test separation distance is 50 mm, and
for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation
distance is < 5 mm, a distance of 5 mm according to 4.1 f) is applied to determine SAR test exclusion.
4.2. IC SAR test exclusions per IC RSS-102 Issue 5
IC RSS-102 Section: 2.5.1 Exemption Limits for Routine Evaluation SAR Evaluation
SAR evaluation is required if the separation distance between the user and/or bystander and the antenna
and/or radiating element of the device is less than or equal to 20 cm, except when the device operates at or
below the applicable output power level (adjusted for tune-up tolerance) for the specified separation distance
defined in Table 1. Output power level shall be the higher of the maximum conducted or equivalent isotropically
radiated power (e.i.r.p.) source-based, time-averaged output power.

Note1: We will use the most conservative source based duty cycle for all the radios.
Note 2: The load base Duty cycle for UMTS is based on a worst case scenario where the pet is outside the geo-fence and in close
contact with a person, and the owner is continuously requesting location information which is a max of 100 byte payload being
uploaded every 90 seconds and using a worst case 12.2kbit/s RMC uplink coding rate (excluding overhead, with lowest order
modulation, and lowest coding rate).
The load base Duty cycle for WiFi is based on the scenario where the pet is inside the geo-fence and using the single worst daily
transfer rate found over 797 Device days of 19.7 Megabytes with a worst case coding for 1mbps.
The load base Duty cycle for BTLE is based on the broadcast packet of 29 bytes every second with a conservative 250kbps
transfer rate.

Note1: For Industry Canada we add positive antenna gain as appropriate to the conducted output power as a worst case.

5.2. Justification for use of load based time averaging
Based on information provided by Whistle I used the worst case loading found for each of the radios as
outlined in the notes in Section 5.1.
5.3. Justification for using the 5 mm Distance
The distance is conservative at 5mm as the device is worn around a pets neck, and to get this close to the
device would be quite challenging.
