Page 4Page 4 of 6 1 Introduction 1.1 Purpose and Scope This document includes the information of the NextNav WAPS Beacon system A4P‐100‐0004‐05 that is required for the network deployment and Network Operations Center (NOC) operator. 2 Product specification The WAPS beacon system is intended to be used in restricted access locations (RAL) in indoor and outdoor environments under all weather conditions. The WAPS beacon is a battery backed system, and is provided with two 12 volt batteries approved for use in telecommunications equipment. WAPS Operating Temperature: -40 Deg C to +50 Deg C operating Storage temperature: -55 Deg C to +80 Deg C Humidity: 90% non-condensing. WAPS weight: 200 lbs with batteries installed, 150 lbs prior to battery installation. Power rating: 120VAC, 60Hz, 5 AMP 3 Equipment List: • NextNav WAPS Beacon • Antenna – Transmit Omni – GPS : L1 GPS (BL1R‐A‐XTB‐1‐FKM) • Cables – TX antenna cable: As per chart below: Main Feed Length Cable Type Jumper Top Jumper Bottom <50’ LDF4 (1/2”) None None 51’‐130’ LDF5 (7/8”) None None 131’ ‐250’ LDF 7 (15/8”) ½” X10’ ½” X 6 ft – GPS antenna Cable: (not to exceed 100 feet ) GPS cables are pre‐fabbed and available in three lengths: 25’, 50’ and 100‘. The cable is an LMR 240 or equivalent (1/4”) and is pre‐terminated with mating ends N male for connection to the beacon and TNC Male for the antenna end.

Page 5Page 5 of 6 4 Antenna Mounting 4.1 TX Antenna Omni antenna to be installed on tower or roof top construction as defined in site specific construction drawing. As a general rule on any monopole installations the TX antenna shall be attached to a 6 foot side arm mount , minimum distance away from the monopole unless the antenna extends above the monopole in its entirety. Likewise the antenna shall be kept a minimum distance of 6 feet from any other vertical structures on other types of towers. For roof tip installations, the TX antenna must extend above all parapet walls and penthouses on the roof top. This radio transmitter (FCC ID: A4P‐100‐0004‐05) has been approved by FCC to operate with the antenna types listed below with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device. This radio transmitter may only operate using a vertically polarized antenna with maximum gain of +8 dBi. To reduce potential radio interference to other users, the antenna gain should be so chosen that the equivalent effective radiated power (ERP) does not exceed 30 Watts. Antenna Type: Monopole Polarization: Vertical Maximum Gain: +8 dBi (maximum gain of antenna + cable loss is 3dBd) A CSV file (configuration file) per transmitter are created by the NOC engineer based on the installation parameters such as line lengths, antenna type etc. The TX output power level setting is contained in the CSV file. The output power is adjusted by the ‘attenuation’ setting This value in the CSV file is calculated by a formula to set the output power (not to exceed 30W EIRP) . The variables used in the calculation include PA Gain (G pa ), TX Antenna Gain (G ant ), TX filter insertion loss (IL flt ), internal cable loss (IL int ), external cable loss (IL ext ), and transceiver output power (P TCVR ). EIRP (W) = 10^((P TCVR ‐ IL int + G pa ‐ IL flt ‐ IL ext + G ant ) / 10) / 1000 Document Name: WAPS Beacon NOC User Manual Document No: TGR‐NN‐OP‐102.00‐Rev1.0 Version No: 1.0 Company Name: NextNav, L…

FCC Home | Search | RSS | Updates | E-Filing | Initiatives | Consumers | Find People Office of Engineering and Technology Inquiry: In order to qualify for certification, does M-LMS transmission equipment intended to be used by an M- LMS licensee that holds both the B and C block licenses in a market need to be capable of attenuating its transmissions at the 921.75 MHz band edge between the lower B block (919.75-921.75 MHz) and the lower C block (921.75-927.25 MHz) when applying the out of band emission mask indicated in Section 90.210(k)(1) of the Commission's rules? Response: The following response has been coordinated with the Wireless Bureau. A licensee authorized to operate in both the B and C blocks can use equipment that does not attenuate its transmission at 921.75 MHz boundary between the B and C blocks . For Certification of equipment subject to 90.210(k)(1), which applies to wideband multilateration transmitters, for any emission, manufacturers have the option for testing for Certification for B block , C block, and/or an aggregated B and C block. When applying for Certification for an aggregated B and C block, the attenuation requirement at 921.75 MHz is not required. We note that while equipment certification ensures that a type of equipment meets the technical requirements of a given service or band, the licensee is responsible for ensuring that it can operate that piece of equipment legally. For example, while equipment may be approved to operate in aggregated B and C blocks (see 90.209(b)(5) footnote 4 and 90.353(f)), a licensee that operates equipment without attenuation at 921.75 MHz would need to have authority to operate equipment in both of these blocks in that particular market, and a licensee only holding the B or only the C block license in a particular market could not legally operate that piece of equipment.
