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.

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.

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.
