PX8RA-5700-R Operation Description The RA-5700-R is Remote Unit of Multi-band Distributed Antenna System RA-5700, which is an RF over fiber solution that can enhance a wireless network’s coverage by extending cellular services from existing cell sites for both indoor and outdoor applications. The Remote Unit (RU) is modular designed up to support 3 independent inputs, for example 700MHz, 850MHz and 1900MHz. It is modular designed so that each unit can accommodate up to 3 independent bands. On the DL, combined signals as 700MHz, 850MHz and 1900MHz from the BTSs converted into optical signals after amplification in the MU. Then the optical signals are transmitted to the RU via optical fiber. The Optical TX/RX Module of RU converts the DL optical signals into RF signals. After amplification, the signals are transmitted at the MT port to the service antenna. On the UL, the signals transmitted by the mobile are converted into optical signals, and then via the UL optical fiber. PX8RA-5700-R is Remote unit of RA-5700 system The Downlink RF output power, gain, maximum input power, supply power are list in the following table.

For single phase AC power source, the product must be grounded by connecting the “earth wire” of the power cord to the ground terminal of the AC supply. For operating this product with DC power system (such as rectifiers), the product should not be connected to power systems that switch open the return lead because the return lead could function as the ground (earth) connection for the equipment. Protective Ground Connection The enclosure must be grounded securely by connecting a copper wire (CSA 16mm 2 ) to the grounding terminal on the equipment/rack, and the other end to a protective ground (i.e. building earth point). An internationally acceptable colour code of the ground connection wire is green/yellow. Such a ground connection implements the “Protective Ground Connection”, and must be connected to the equipment at the designated ground point. In general, do not connect the supply before establishing an adequate ground (earth) connection. MU Grounding Connection Connect the grounding terminal located on the back panel of MU to a protective ground (i.e. building earth point). RU Grounding Connection The equipment must be grounded securely. Connect a copper wire to the grounding terminal on the mounting tab/enclosure, and connect the other end to a protective ground (i.e. building earth point). An internationally acceptable coloring code of the ground connection wire is green/yellow. 1.2 LI-ION BATTERY CONNECTION Li-ion battery is provided with this system to ensure power is supplied to the system monitoring unit and MCU and to ensure the alarm message could be sent to OMC effectively in case of mains power failure. Caution: Be careful of the risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to the instructions.

ATTACHMENT FCC ID: PX8RA-5700-R ** MPE Calculations ** Environmental evaluation and exposure limit according to FCC CFR 47part 1, §1.1307, §1.1310 The calculation was done for required safe distance. Limits for General Population/Uncontrolled Exposure Note. This MPE calculation is worst case: 1. 700MHz and 850 frequency band Maximum permissible exposure is Freq. (MHz)/1500 = MPE mW/cm 2 Freq = 733 MHz, 733/1500 = 0.488 mW/cm 2 2. 1900MHz band: The maximum permissible power density is =1 mW/ cm 2 Max Tx output power at antenna input = 30 dBm = 1000 mW Maximum Antenna Gain = 6 dBi, so the numeric gain = 4 (dBi) The maximum RF power from Antenna = 36 dBm (EIRP) = 4000 mW (EIRP) MPE Calculation at worst case: Estimated safe separation: R = √(PG / (4π* 0.488)) R = √(1000 * 4 / (4π*0.488)) R = 25.55 cm Where, P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20cm = limit for MPE) The minimum safe distance for Occupational/Controlled exposure is 25.55cm for the antenna when installed. This is the worst case for the downlink. The maximum antenna gain stated is for the downlink. This product is installed by trained professionals in outdoor applications only
