Human Exposure to Radiofrequency RF fields – calculations as defined by EN50385:2002 and OET65 V03 Confidential Confidential 2 Overview This document shows the calculation of the compliance boundary for the Umbra product to meet the basic restrictions as defined in EN50385:2002, and those defined in 0ET65 Edition 97-01. The limit defined for a device operating at 28GHz according to Council Recommendation 1999/519/EC is 10W/m 2 . The limit for occupational exposure according to OET65 is 5mW/cm 2 (50W/m 2 ). The limit for general population exposure according to OET65 is 1mW/cm 2 (10W/m 2 ). Device characteristics – Standard Umbra Node The Umbra node emits RF energy on a single RF channel. The maximum RF power at the filter output is 25.3dBm (with QPSK modulation). The RF energy then passes through an RF switch module before being fed to the selected antenna. The minimum loss of this switch module is 3dB. Therefore the worst case output power at the antenna is 22.3dBm. The maximum gain of the antenna is 19.5dBi. Calculation of compliance boundary for general public exposure The far field (spherical) calculation method defined in 8.3.2. of EN 50383 has been used to define the compliance boundary, using the maximum gain noted above. As noted in 8.3.2., this gives a conservative result (it overestimates the field strength). Therefore the exposure at the distance calculated below will be well within safe limits. S= Power Density – basic restriction is 10W/m 2 P= Output Power G= Gain (relative to isotropic) r= compliance boundary radius S=(PG)/(4PIr 2 ) Therefore: r 2 =(PG)/(S4PI) r 2 = 15.14/(10 x 4PI) r = 35cm (For occupational exposure, according to OET65, r=16cm) Confidential 3 Device characteristics – Umbra High Gain Node The Umbra node emits RF energy on a single RF channel. The maximum RF power at the filter output is 25.3dBm (with QPSK modulation). The maximum gain of the antenna is 34dBi. Calculation of compliance boundary for general public exposure The far field (spherical) calculation method defined in 8.3.2. of EN 50383 has been used to define the compliance boundary, using the maximum gain noted above. As noted in 8.3.2., this gives a conservative result (it overestimates the field strength). Therefore the exposure at the distance calculated below will be well within safe limits. S= Power Density – basic restriction is 10W/m 2 P= Output Power G= Gain (relative to isotropic) r= compliance boundary radius S=(PG)/(4PIr 2 ) Therefore: r 2 =(PG)/(S4PI) r 2 = 851.14/(10 x 4PI) r = 2.6m (For occupational exposure, according to OET65, r=1.2m) Installation guidance to ensure general public are outside compliance boundaries The Umbra product is designed to be mounted on street furniture (e.g. lampposts) adjacent to small cellular basestations. The equipment is necessarily mounted out of reach of the general public for the following reasons: 1. To avoid interference with the equipment by the general public 2. To avoid blocking of the radio signal by passing traffic e.g. double-decker buses – requires installation height greater than 5 metres Therefore the equipment is only accessible to authorised personnel.

Electronics Limitedand, where appropriate, conforms to the relevant subpart of FCC 47CFR Part 101. This is a certificate of test only and should not be confused with an equipment authorisation. Other standards may also apply. Equipment:UMBRA Model Number:V4 Proposed FCC ID:2ACV4-UMBRA28-001 Unique Serial Numbers:227 (29.1875 GHz unit) 229 (28.2485 GHz unit) 231 (27.6045 GHz unit) Applicant:Cambridge Communication Systems Ltd 3 rd Floor Mount Pleasant House Huntingdon Road Cambridge CB3 0RN United Kingdom Full measurement results are detailed in Report Number:09-7558-1-14 Issue 01 Test Standards:FCC 47CFR part 2J and part 101C effective dateOctober 1 st 2013, Class TNB Intentional Radiator DEVIATIONS: None. This certificate relates only to the unit tested as identified by a unique serial number and in the condition at the time it was tested. It does not relate to any other similar equipment and performance of the product before or after the test cannot be guaranteed. Whilst every effort is made to assure quality of testing, type tests are not exhaustive and although no non-conformances may be found, this doesn't exclude the possibility of unit not meeting the intentions of the standard or the requirements of the Directive, particularly under different conditions to those during testing. Any compliance statements are made reliant on (a) the application of the product and use of the assigned band being acceptable to the FCC and (b) the modes of operation as instructed to us by the Customer based on their specific knowledge of the application and functionality of the EUT. Statements of compliance, where measurements were made, do not include the measurement uncertainty. The measurement uncertainty, where stated, is the expanded uncertainty based on a standard uncertainty multiplied by a coverage factor of k=2, providing a level of confidence of approximately 95%.
