Active DAS Hybrid In-Building Signal Enhancing Solution for Business

For quality in-building cellular signal coverage solution, you simply can't beat our Cel-Fi Quatra Active DAS (Distributed Antenna System) Hybrid Array Solution. Compatible with both single and multiple carrier environments, ours is a scalable solution and the most sustainable, cost-efficient DAS for enterprise solution for deployments between 20,000 ft.² and 200,000 ft.² Our active DAS hybrid in-building signal enhancing solution for business commercial buildings costs a fraction of installation time and cost of other signal enhancing solutions for businesses of similar size and in-building coverage requirements.

Importantly, our Active DAS Hybrid Array Solution is already carrier and FCC-approved and completely network safe for data and voice. Since our Active DAS is carrier pre-approved, there are no long waiting periods for FCC approval, carrier approval, multiple carrier specific systems, or carrier fibre-optic backhaul integrations. When you choose an Active DAS Hybrid Solution for enhanced cellular signal coverage in your building, you're no longer forced into lengthy delays or the unnecessary expense of older DAS systems.

Key Advantages of Our Active DAS Hybrid Array Solution.

  • Our Active DAS Hybrid Array solution is pre-approved for major carriers like Verizon, AT&T, Sprint and T-Mobile.
  • With this signal solution, there are no unnecessary waiting periods for carrier approval.
  • 100 dB maximum gain is achieved simultaneously in each band.
  • Peaceful co-existence with Wi-Fi, Femtocells, and other cellular devices.
  • Signal quality is optimized by intelligent antenna aiming.
  • Advanced digital echo-cancellation (>30 dB) and channel select filtering algorithms.
  • Continuous self-configuring and optimizing to environmental changes.
  • Automatic gain control (AGC) based on fast real-time echo cancellation.
  • (PoE) Power-over-Ethernet; and RFoE (RF-over-Ethernet).

Our Active DAS Hybrid system has been designed specifically as an advanced solution to dramatically improve indoor cellular connectivity without any interference to the mobile network. This removes hassles of carrier complaints down the road causing expensive modifications. This advanced solution is a network arrangement of independent Active DAS Hybrid systems, with each system consisting of its own Intelligent Donor Antenna (DA), Coverage Units (CUs), and Network Units (NUs). Since the signal from the Coverage Units is broadcast spherically, the number of required interior components is dramatically reduced, particularly when it comes to multi-floor venues. Small Cell(s) can also be incorporated to enhance system if needed with multiple Cel-Fi Quatra systems resulting in creation of Super Cell(s).

Network Units power the system, with Power-over-Ethernet (PoE) and RF-over-Ethernet (RFoE) being distributed from the Network Units to the Coverage Units. As signal is being distributed over Ethernet, it leaves a smaller footprint, requires much less electricity to operate than older systems, and has a lower maintenance cost. Furthermore, since the system continuously self-configures and self-optimizes to avoid interference between the Coverage Units, Wi-Fi networks and mobile networks, it is considered unconditionally network safe. The system can support all technological platforms including WCDMA, HSPA+, LTE (FDD), with MIMO in supported networks.

Our Service Plan provides management and real-time monitoring of our Active DAS Hybrid Array Solutions.

The Required Site Survey.

During the Site Survey, signal readings will be taken from both inside and outside the building. Measurements from Google Earth for the building's exterior length and width dimensions will very quickly determine the square footage of the building's interior. Areas such as office spaces, production floor and warehouse spaces will be inspected to determine the perfect installation sites to provide consistent, superior wireless coverage throughout the building.

Next, we will obtain an average LTE-decibel reading on the roof of the building at the proposed location of the donor antenna. An average of 50 signal readings in dB will then be taken at atleast 10 interior locations based on building area, which will determine interior dB loss compared to outside signal strength. As dB power is logarithmic, the building's interior cellular signal could be more than four times weaker than the surrounding signal of the building.

A strong system for possible anticipated disrupting factors.

It will be anticipated that during times of network congestion, bad weather, etc., there will be further degradation of the signal in the building's interior, which could well affect cellular coverage in the production floor buildout, the office area, and the warehouse buildout. The radio frequencies which transmit cellular data and voice signals can be dramatically affected by everyday materials like stone, metal, and glass, and this problem is only exacerbated when it comes to manufacturing and production, simply due to the volume of material and equipment.

In addition, if the building itself is situated along a busy highway, the morning and evening rush hours could well produce Macro Network capacity issues. While anticipations will be built into the design plan accordingly so that required in-building cellular coverage remains at minimum required threshold, we strongly recommend installing an Active DAS Hybrid Array Solution in your building to help us achieve consistent mobile coverage perpetually.

Powered by Cel-Fi QUATRA 2000 for AT&T & Verizon or Cel-Fi Quatra 2000 for T-Mobile & Sprint, our Active DAS Hybrid Array Solution is a self-optimizing, intelligent signal solution that surpasses other solutions in complex manufacturing and warehouse environments.

  • I was asking about distributed antenna system (DAS) companies and what they do. I have seen and heard about cell phone boosters and how these devices can make cell phones work better wherever the boosters are installed. I’ve been told that distributed antenna system design is a way to boost cell phone signals throughout an entire building. It’s especially useful for buildings where its structural materials play havoc with cell phone signals, either killing them or weakening them. A DAS system installation will help you avoid these lapses in signals and a DAS installation company will help you plan the installation thoroughly, so things run smooth.

  • Question: What is the difference between getting a cell phone booster for a building and getting a DAS system?
    Answer: There are cell phone boosters you can buy for a large building that will strengthen your signal throughout the building so people can make calls without worrying about dropped calls or bad call quality (the boosters can also translate into faster data speeds, longer battery life for a phone, and other benefits). In some cases, a building is made up where a cell phone booster is going to face interference from building materials. A DAS system gives you the same benefits as a booster, but it is set up throughout your building, so you have strong signals everywhere whether it’s in the building’s basement, or an area surrounded by concrete or other signal-weakening material.
