Passive DAS Array In-Building Signal Improving Solution for Business

Today's Passive DAS (Distributed Antenna System) Array Solutions are a combination of key components that make it work. These components are: Quality Assurance, our industry-leading team of Design Engineers and Certified Integrators, and absolute best cellular signal boosting equipment available on the market today. When it comes to sustainable, high-quality interior cellular data and voice connectivity, there's no, "one size fits all" solution. Therefore, Passive DAS business cell phone signal booster kits are custom-designed and manufactured to meet or exceed the connectivity needs of your building.

Following the installation and commissioning of our systems, our solutions are tuned to maximize longevity and system performance. Passive DAS Array In-Building Signal Improving Solution for Business are very sustainable and cost efficient systems, helping enterprises cover cellular coverage distributions of up to 250,000 ft.²

Key Advantages of Passive DAS Array Signal Improving Solutions.

  • These solutions are pre-approved for major carriers like Verizon Wireless, AT&T Wireless, Sprint, and T-Mobile.
  • They provide up to 70 dB maximum gain, without added expense or having to wait for carrier approval.
  • When compared to Active DAS, Passive DAS Array Solutions are quickly and professionally integrated at just a fraction of the cost.
  • These solutions are custom designed and manufactured to the specific needs of your building and its operating environment.
  • Passive DAS Array Solutions are tuned to maximize longevity and system performance without interfering with other wifi and mobile networks.

Reliable Cellular Coverage.

In order to deliver excellent cellular signal coverage, only the very highest-quality equipment and components are used in our Passive DAS. Examples of bi-directional amplifiers (BDA) include SureCall Force 5 2.0 and Wilson Pro 1050. Compatible with both single and multiple carrier environments, ours is a scalable solution that is sustainable and cost efficient.

Designed specifically to cause no interference to the mobile network, our Passive DAS is a cutting-edge solution that has been specifically engineered to enhance indoor cellular connectivity for data and voice. Serving as a transmitter between users within your building and carrier cell towers, our Passive DAS solution is a system comprising of (DA) Donor Antennas, (AMP) Amplifiers, and (BA) Broadcast Antennae.

Connecting "Off Air" with the cell towers, the DA sends a signal to the Amps; the signal is then amplified, with the Amps distributing both power and RF (Radio Frequency) via coaxial cable to the BAs. That amplified donor signal is broadcast via the BAs to the interior of your building, supplying all cell devices with reliable cellular data and voice signal. Conveniently, since amplifiers and related components are FCC-approved, it is not necessary to seek carrier and/or FCC pre-approvals before installing your solution as long it is installed by our professionally trianed and certified installers.

The Required Site Survey.

Signal readings will be taken from both inside and outside the building. Then, using Google Earth's measurements of exterior dimensions of the building, we can quickly determine the square footage of interior of the building. In order to ensure installation provides consistent and reliable wireless coverage throughout interior spaces, building areas like production areas, warehouses, and office areas will be inspected.

Next, several exterior LTE -dB readings will be measured along the periphery of the roof to determine proposed location of the donor antenna. Thereafter, approximately 50 accurate signal readings will be taken in dB using our commercial grade signal meter at all designated internal weak signal locations, representing interior dB loss as compared to outside signal strength. Because dB power is logarithmic, the cellular signal within interior of the building could be more than four times weaker than the signal environment surrounding the building.

Planning to compensate for future unavoidable signal degradations.

During times of network congestion, bad weather, etc., further degradation of the signal within the building is expected. Such events impact cellular coverage in the production floor buildout, the office area, warehouse buildout, and other niche sections of the building where cell signals are required to be very good consistently. Radio frequencies can also be affected by everyday materials like glass, water, stone, and metal; which reflect the RFs on which cellular data and voice signals are transmitted. The problem is further exacerbated in manufacturing and production environments, simply due to the volume of material and equipment. Plus, if the building in question is situated on a major highway, Macro Network capacity issues will likely be experienced during the morning and evening rush hours.

Choose a Passive DAS Array Signal Boosting Solution.

In addition to current signal issues you may be facing, compensating for future possible further signal degradations as stated above, we recommend a robust Passive DAS Array Solution installed in the building. Powered by two Force5 2.0 or WilsonPro 4000R amplifiers, our Passive DAS Array Solution is a powerful Carrier Agnostic resolution in such instances because it has been specifically designed to excel in combinations of large office and manufacturing/ office and warehouse environments.

Should you have any queries at all about our Passive DAS Array Solutions, please don't hesitate to contact us. We look forward to resolving your cellular signal problem in your new building because we understand that, yes, signal is important, but it is not as important as the people working in and visiting your building who depend on reliable cellular signal.

  • It’s always good to see the price disclaimer because today’s current economy is full of cases where prices are constantly rising due to the coronavirus. Stuff like construction materials, food, and I bet passive DAS equipment. As long as the seller is upfront, I don’t mind (unless the price hike is ridiculous in which case I’d have to pass).

  • What kind of price difference are you talking about between active distributed antenna systems and passive ones? I know this blog states passive is a “fraction of the cost,” but is it really that cheaper? In terms of power, will passive DAS do everything you want it to? I know cell phone signal boosters can help out at home, in vehicles, and buildings, but when it comes to a system like this, I’d like more details.

  • This blog provides a good understanding of distributed antenna systems, something that sounds complex, but isn’t too bad once you read this article. Cell phone boosters are very helpful, but as this article explains, buildings can have a number of issues that degrade cell phone signals, even when you have an interior cell phone booster. You’ll want a professional survey before you have your 4G DAS installed so you have the best distributed antenna system architecture for your building. That way you have everything accounted for and your DAS system works well for you, making for strong cell phone signals throughout your building.

  • Business owners are letting employees use mobile devices on the job, creating opportunities for greater efficiency and (naturally) greater communication. The problem many people run into is that office buildings often have dead zones where there are no signals or areas where signals are so weak they might as well be dead zones. If employees are working all over the building, they should have reliable cell phone signals all over the building. That’s where a passive antenna system can help ensure a strong signal throughout the building (as this article mentions). There are some pre-installation steps before you set up your DAS components, but they’re worth the time and planning. Once your employees have reliable cell phone signals, they’ll be able to do their jobs better and will have one less thing to be stressed about.
