Digital Multi-Band Modular RF Repeater

With the accelerating development of mobile communication technology, additional communications technologies and Frequency Bands are being added by Operators. Hence, telecom operators have to handle multi-Bands and Technologies simultaneously. They also face the potential issue of re-farming spectrum resources.
A standard integrated Repeater cannot easily be upgraded, wasting Operator's Repeater investments.
To address this issue, Helios has developed our Cardmux Series Digital Multi-Band Modular RF Repeaters.
It provides software-based platform and enables on-the-fly filter to be changed/upgraded by software without expensive hardware upgrading. It supports both multi sub-bands selective (bandwidth tunable) and/or channel selective function. It is a standard 19" rack design and support upgrading from Single Band to Dual Band/ Tri Band and even Six Band with just adding separate RF Cards easily.
Helios Digital Multi-Band Modular RF Repeater is a cost-effective and intelligent solution that solves the last mile coverage problem, and multi-bands operating supporting all major cellular frequency bands including 700MHz, 800MHz, 1800MHz, 1900MHz, 2100MHz or 2600MHz and supports all major wireless technologies include GSM, EDGE, DCS, CDMA, UMTS, LTE FDD.
The Repeater is connected via coaxial cable to a Donor Antenna and Service Antenna or DAS, The Donor Antenna is placed outside the building where it has access to a BTS signal, and the Service Antenna or DAS are placed in the building where they can extend radio coverage to the areas lacking coverage.


Key Feature

  • Up to six bands operating supporting all major cellular frequency bands including 700MHz, 800MHz, 1800MHz, 1900MHz, 2100MHz or 2600MHz.

  • Supports all major wireless technologies include GSM, EDGE, DCS, CDMA, UMTS, LTE FDD.

  • Multiple RF Cards can amplify the same frequency band in order to address LTE MIMO 2x2 or 4x4.

  • Band Selective or Channelized based upon Software Defined Filtering, and BW or number of filters can be tunable or upgradeable by software.

  • Modular scalable architecture allows user to quickly modify, upgrade or expand repeater platform by simply adding additional RF cards and software features.

  • Supports upgrading filter parameters in case of frequency re-farming by software.

  • Innovative Digital Filtering technology basis on DSP and SDR to provide excellent signal selectivity and minimum time delay.

  • Better out of band rejection than analog SAW filters.

  • Unique max AGC 60dB firmware to ensure stables operating on moving platforms such as ship or trains.

  • Compatible with baseband hoping and synthesized hopping.

  • Built-in IP Web Browser GUI and RJ-45 port for local control.

  • Built-in 2G or 3G or 4G modem as option for remote control.

  • Built-in individual AGC & ALC functions for each sub-band for multi-operator and public safety applications.

  • High working Gain min. 95dB and cost-effective solution making coverage more affordable for small building or driving a DAS in large buildings.

  • RF composite power +33dBm to +43dBm for medium & large coverage application.

  • 19" rack mount both for indoor use and outdoor use with additional waterproof cabinet.


Application

To expand cellular signal coverage of fill signal blind area where signal is weak or unavailable.
