Product Description

Long Term Evolution (LTE) is a standard for wireless communication of high-speed data based on GSM and UMTS network technologies. The standard has been developed by the 3rd Generation Partnership Project (3GPP). The goal of LTE is to increase the capacity and speed of wireless data networks. LTE standard has been developed in TDD and FDD versions.

While both LTE TDD (TD-LTE) and LTE FDD will be widely used, it is anticipated that LTE TDD will be the more widespread and deployed, because LTE TDD has a number of significant advantages, especially in terms of higher spectrum efficiency that can be used by many operators.

For operators, they must optimize their network and offer best service to users to improve their competitive ability. However, and 3G signals attenuate severely when traveling through walls, floors, and windows, leaving more than 40% 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 arithmetic, the Repeaters will be unable to be normally switched between the different time-slots for uplink and downlink, even will cause big interference in network.

Helios TDD-Mate series TD-LTE RF Repeaters are specially designed for the TD-LTE systems with the own patented TDD-Mate Series TDD SYNC Module, which is basis on FPGA & DSP (Digital Signal Processing) platform with Helios patented TDD Frame Synchronization arithmetic, It receives TDD signals from BTS and down-converts to IF signals firstly, then digitalizes the signal via high speed ADCs (Analogue to Digital Converter) and implements baseband digital demodulation on DSP, and finally identifies DwPTS (Downlink Pilot Time Slot) including Primary Synchronization Signal and Secondary Synchronization Signal to acquire the switch point between UpPTS (Uplink Pilot Time Slot) and DwPTS by verifying correlation between the local Primary & Secondary Synchronization Code and demodulation signals basing on the correlation property of Synchronization Code. The synchronization accuracy can reach to 99.9% with Helios patented TDD Frame Synchronization arithmetic.


Support single band TD-LTE2300MHz, 2500MHz and 2600MHz.
Built-in Patented frame synchronization algorithm for TDD system to ensure accurate synchronization and eliminate interfere to Donor BTS.
High working gain as Min. 85dB significantly improves 4G TD-LTE network capacity for operators.
RF output power +27 to 33dBm for medium coverage area.
Accurate ALC & AGC for each time-slot basis on high speed FPGA to ensure reliable working.
Innovative Digital Filtering technology basis on DSP and SDR to provide excellent signal selectivity and minimum time delay.
Significantly improve data rates in both weak signal areas and most area with good signal areas.
Lower cost of indoor coverage and rapidly increases capacity of 3G or 4G wireless networks.
Significantly improve Battery Life of subscribers' handset and UE.
