To Whom it May Concern, The Dense Air STC-v11-Node-n77, Model: AAB contains a single sector 5G radio consisting of a 2x2 MIMO 5G radio with integrated switched beam system with external antenna arrays and integrated 60GHz beam steered mmWave radio for backhaul. The equipment is considered to be fixed equipment and intended for operation with separation distances greater than 20cm between any person and the equipment. Therefore the RF Exposure performance can be assessed by a Maximum Permissible Exposure (MPE) calculation using the limits defined in Part 1.1310(e)(1) Tables (i) and (ii). The equipment incorporates two independent radio transmitters that can operate simultaneously, each transmitter has been assessed individually to confirm compliance with applicable MPE limits. Additionally, the combined RF exposure under simultaneous transmission conditions has been assessed. This was assessed by applying section 7.2 for Transmitters used in mobile devices exposure conditions for simultaneous transmission operations in FCC KDB 447498 D01 v06 to ensure the sum of the MPE ratios is ≤1.0. The equipment architecture allows the radiating structures to be divided into two distinct groups with each group consisting of both 5G and 60GHz antennas where the worst-case exposures can occur. Each antenna grouping is described as a physical sector only due to their mechanical alignment, the two physical sectors are considered to be identical to each other. This analysis will consider the RF exposures from a single physical sector consisting of a pair of 5G antennas and a single 60GHz mmWave radio. The operation of the 5G radio and 60GHz radio are not synchronised, they are considered to operate under simultaneous transmission conditions. The 5G radio operates in the 3.7-3.98GHz 3.7GHz Service band under FCC Part 27 using Time Division Duplex with maximum transmitter duty cycle of 75%. The 60GHz mmWave radio operates in the 57-71GHz band under FCC Part 15.255 with a maximum duty cycle of >99%. The 60GHz radio is beam steered ±45 o in the azimuth plane, the worst-case DocuSign Envelope ID: 76BC92D6-B933-40B9-9436-B7DB59787E6B www.denseair.net Dense Air Networks: Atlas House, Third Avenue, Globe Business Park, Marlow, Bucks, SL7 1EY, UK Tel: +44 (0) 1628 477663 / Company Registration: 10402747 simultaneous transmission exposure condition occurring when the beam is aligned with the 5G radio antenna 3dB beamwidth peak. The 5G radio supports a Switched Beam Antenna system, for the RF exposure calculations, the modes with the highest EIRP will be assessed for MPE compliance. Part 27 5G Radio System Analysis The 5G radio in the equipment is a 2x2 MIMO radio, internally the RF outputs are split in the Switched Beam Antenna system. Each RF output from the internal 5G radio provides a single RF carrier, the RF carriers in the 2x2 MIMO radio are not correlated with each other. The SBA circuit switches and splits each carrier into multiple signals, these signals are correlated and will create array gain when both antenna arrays in the physical sector are enabled. The 5G antenna system comprises of 4 individual panel arrays with 2 arrays mounted in each physical sector on the enclosure, each antenna array is a ±45 degree dual cross-polarised array with gain of 14dBi. The total power radiated from each array is the combination of the power from each polarisation. The maximum conducted RF power available at any of the 8 RF connectors is up to +27dBm per carrier, this analysis focuses on a single physical sector of the equipment as both physical sectors are the same. The conducted RF power on each port will change based on the selected SBA mode due to the varying RF paths selected. This analysis is based upon the worst-case operating modes of the switched beam antenna (SBA) system. The MPE calculations will assess the combined MPE from both polarisations from a physical sector for the following worst-case scenarios. a) where the SBA system enables one antenna array in the physical sector the SBA insertion loss is 6dB. b) where the SBA system enables both antenna arrays in the physical sector the SBA insertion loss is 10dB.
