Product Description
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 RF Repeater is designed for TD-LTE telecom operator who looking to enhance TD-LTE coverage where cellular signal is weak or unavailable or poor data throughput. It will be connected via coaxial cable to a outside Donor Antenna and Indoor Services Antenna, Donor Antenna is placed outside the building where it has easy access to TD-LTE BTS signal, and the Services Antenna is placed in the building where it can extend TD-LTE radio coverage to the blind area.

FEATURES
1)Support single band TD-LTE2300MHz, 2500MHz and 2600MHz.
2)Built-in Patented TDD-Mate™ Frame synchronization algorithm for TDD system to ensure accurate synchronization and eliminate interfere to macro network.
3)High working gain as Min. 85dB significantly improves 4G TD-LTE network capacity for operators.
4)RF output power +24 to 33dBm for small & medium coverage area.
5)Build-in Intelligent Carrier Scan Function (CSF) and auto local cell with best QoS and RSSI by PSS & SSS, likewise support manually lock expected carrier by software.
6)Flexible TDD UL/DL Allocations configurable by software (0 to 6), default UL/DL Ratio is 1.
7)Configurable field length of DwPTS/GP/UpPTS by software (0 to 8).
8)Both support Normal CP (Cyclic Prefix) and Extended CP.
9)Innovative Digital Filtering and advanced baseband algorithms in SDR to provide accurate AGC, MGC and Power Control for each time slot with minimum time delay.
10)Significantly improve data rates in both weak signal areas and most area with good signal areas.
11)Lower cost of indoor coverage and rapidly increases capacity of TD-LTE wireless networks.
12)Significantly improve Battery Life of subscribers' handset and UE.
13)Automatic Gain Control (AGC) continuously monitors path loss and transmit power to deliver max gain.
14)Built-in wireless modem for remote monitoring by SMS, GPRS or TCP/IP.
