Fujian Helios Technologies Co., Ltd. www.heliostelecom.com 4 Warning The product has been tested and found to comply with the Federal Communications Commission(FCC) RF Exposure Requirements,pursuant to FCC Part 27. The Manufacturer’s rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5dB,especially where the output signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device. In order to comply with the FCC RF exposure requirements, the BDA-CELLAB/PCSF-33/33-80-AB antenna installation must comply with following: The base station antenna must be installed so as to provide a minimum separation distance of 60cm between the antenna and persons within the area.This antenna should with gain less than 11dBi ,VSWR≤1.5:1,ZO=50ohms) The service antenna must be installed so as to provide a minimum separation distance of at least 25cm between the indoor antenna connected to the RF booster and the human user’s body within the area. This antenna should with gain of 0-7dBi,VSWR≤2:1, ZO=50ohms. INSTALLATION WARNING:This is NOT a CONSUMER device.It is designed for installation by FCC LICENSEES and QUALIFIED INSTALLERS.You MUST have an FCC LICENSE or express consent of an FCC Licensee to operate this device.Unauthorized use may result in significant forfeiture penalties,including penalties in excess of $100,000 for each continuing violation.
Fujian Helios Technologies Co., Ltd. www.heliostelecom.com 5 Thanks for choosing Helios Pico Repeaters, please read the User Manual carefully before using the repeater. 1 Overview TDD-LTE, also known as TD-LTE, was adopted as the evolution of choice for TD-SCDMA, China’s 3G standard. Compare with LTE FDD, LTE TDD uses a different approach, a single frequency sharing the channel between transmission and reception, spacing them apart by multiplexing the two signals on a real time basis. While FDD transmissions require a guard band between transmission and reception, TDD schemes require a guard time or guard interval between transmission and reception. For TD-LTE operators, they must optimize their network and offer best service to users to improve their competitive ability. However, and 4G signals attenuate severely when traveling through walls, floors, and windows, leaving more than 50% of all indoor spaces with inadequate coverage and poor data throughput. Then the operators need a cost-effective solution to resolve such coverage problems easily and rapidly. Repeaters, Boosters and Amplifiers for mobile network are to relay RF signals for both uplink and downlink, they are effective tools to enhance mobile network coverage for telecom operator, but there are one of the key technologies for the Repeaters, Boosters and Amplifiers with TDD mode must be first resolved, which is Frame Synchronization, without accurate & reliable TDD Frame Synchronization with BTS, the Repeaters will be unable to normally switch between the different time-slots for uplink and downlink and working in harmony with macro network, even will cause big air-interference to macro network. With ultra-low-noise RF frontend, innovative digital filter, high SFDR (Spurious Free Dynamic Range) ADC, patented TD-LTE frame synchronization algorithms in SDR, TDD-Mate enables accurate, speedy and reliable frame synchronization with TD-LTE BTS and working in harmony with macro network. It receives TDD signal from BTS and down-converts to IF signals firstly, then digitalizes signal via high speed ADC and implements baseband demodulation on DSP, and Identifies PSS in DwPTS and SSS in TS0 according to TD-LTE frame structure, and acquire the accurate switch point between UpPTS and DwPTS. Helios TDD-Mate series TD-LTE ICS Pico Repeater is designed for industry users looking to enhance TD-LTE indoor wireless connectivity. It will be connected via coaxial cable to an outside Donor Antenna, whereas Service Antenna is built-in inside the repeater. Donor Antenna is placed outside the building where it has easy access to TD-LTE BTS signal, and the Pico Repeater with built-in Service Antenna is placed in the building where it can extend TD-LTE radio coverage to the blind area. 2 Illuminating Uplink: Communication link from handset to BTS. Downlink: Communication link from BTS to handset. Self-oscillation: An amplified signal being received & amplified again by repeater is called self-oscillation that will cause components fault. ICS:The Interference Cancellation System, which can automatically detect and eliminate all multi-path feedback signals. It can moderate the requirements of isolation between donor antenna and service antenna.

With the aid of mobile phone or TEMS, find a suitable place to install the donor antenna on the wall of the building or parapet wall on the top of the building where the signal bar is full and call quality is good. Note that the height of donor antenna should be less than 7 floors or 20 meters to ensure good call quality and avoid interference to the BTS. On the other hand, users should try their best to separate the donor antenna from the area to be covered as far as possible to ensure the isolation between the donor antenna and service antenna. B. Fasten the donor antenna (Yagi or Log antenna) on the selected place, and the donor antenna should face to the BTS direction. C. Fasten the TD-LTE ICS Pico Repeater on the wall where is close to the area to be covered and has available mains socket nearby. The side with Helios logo is service antenna direction which should face to the area to be covered. D. Connect the feeder cable to the donor antenna and run the cable to the BTS port of the TD-LTE ICS Pico Repeater and fasten it along the wall. Note that when the cable goes from outdoor to indoor, the outdoor section should be made U-type bend to prevent water goes into indoor place. Remember to have weatherproofing process for RF connectors. E. Connect the feeder cable to the BTS port of the TD-LTE ICS Pico Repeater and have weatherproofing process for RF connectors. F. Ensure all connections are correct and lock them. Now, the primary installation is finished. G.
