Becoming a VAST DAS Certified location provides you with verifiable proof of the cellular coverage they expect and can lead to increased occupancy rates.

What Causes In-Building Cellular Coverage Problems?

Undoubtedly, at some point within the past 24 to 48 hours, you have experienced a weak or non-existent cell phone signal somewhere along your path, whether it be at home, at work or at play.

Surely, you’d think that the wireless carriers would have added more cell towers, better technology, more capacity and improved coverage areas to accommodate the growing number of devices and users? And, they have. You might still be wondering, “Then why does my in-building cell signal coverage continue to get worse?”

While we have all had our heads buried in our mobile devices, what you probably haven’t noticed – unless you are in the building and construction industry – is that there has been an equally rapid growth in LEED Building Certifications. LEED stands for Leadership in Energy and Environmental Design. Unfortunately, it also means poor cell phone signal and it’s only going to get worse. The same materials that are used to make buildings more energy efficient – such as brick, block, steel, concrete and windows that block UV Light – also block out RF signals which are necessary for cell phones to operate.

Our VAST DAS Certified Program and Risk-Free Guarantee solves this problem.


Every VAST DAS Certified project starts with our state-of-the-art VAST DAS Certified In-Building Walk Test.

Performing a thorough in-building walk test helps

us to identify weak coverage areas. Using this information we are able to design a custom

solution so you don't pay for unnecessary

coverage in areas that don't need it.

Using the In-Building Walk Test results, we will design and install a solution to enhance the weak coverage areas within your building.

Approved by over 200 Wireless Carriers in more than 100 Countries, the CEL-FI QUATRA Hybrid Active DAS Solution provides smart in-building cellular coverage.

Once installed, we will retest your building using the same In-Building Walk Test Analytics to make sure we got it right.

Once satisfied that all problems areas have been corrected, you will receive a VAST DAS Certified Certificate for verifiable proof that you have reliable signal strength and quality.
