1. The Problem

Dense construction materials hindered cellular signal

Our client is a leading furnishings manufacturer and household name. Before RSRF, they were having major problems with cell signal at their new headquarters location. They had just begun construction on two buildings: a 5-story office building and an adjacent showroom/innovation center. They immediately noticed a weak signal throughout the facility, with the most noticeable issues being inside the buildings. Particularly in the office space, the signal was quite poor and they had trouble making calls at all on AT&T or Verizon. As they prepared for move-in and had more inspectors and contractors in their building, the problem only became more pronounced.

The issue ultimately came down to the buildings themselves and the construction materials that were used. The showroom/innovation center was formerly a GM production plant. As such, the buildings were constructed with a ton of dense materials like concrete, steel, and metal. All of this can interfere with cellular signal.

The new buildings were constructed with Low-E glass that was tinted with charcoal. This glass is extremely popular in office spaces because it lowers heat and glare inside the space itself. However, the charcoal blocks a lot of the cell phone signal and acts as a wall for radio frequencies.

The unique structure of the showroom also led to significant signal challenges. While the office space had a fairly straightforward layout - with standard ceiling heights, a drop ceiling, and other usual features - the showroom did not. Instead, it had a mix of really high ceilings, wide-open areas with no ceiling at all, and office space. This is the kind of complex space that can have serious signal issues, so the solution needed to be flexible and we needed to take the unique structure into account.

2. The Solution

3 small cell passive DAS solutions connected to AT&T and Verizon over the Internet

We began by consulting with the client, explaining the ways that we could solve their coverage issue, getting a set of floor plans, and discussing their priorities, budget, and goals. From there, we were able to schedule an initial site survey and provide a preliminary pricing estimate for their approval.

They were looking specifically for improved service with AT&T and Verizon, and they needed solutions that were robust enough to provide 5-bar service throughout the large facilities.

Based on this information and our other findings - gathered from preliminary discussions and our assessment of the space - we found that the best solution for them was a small cell passive DAS solution.

RSRF procures small cell devices directly from AT&T and Verizon, and they can provide robust performance right off the bat. They essentially act like small cell towers (they are smaller than a laptop) and they have a radio chip inside that produces the AT&T or Verizon signal. The buildings get their signal directly from these devices instead of from outside, as is the case with an off-air solution.

We installed one small cell device in the showroom and two devices in the office space.

3. The Results

5-bar coverage throughout the showroom and office space

The installation took a crew of 6 just two weeks to complete. As soon as the installation was finished and the system was activated, they had robust 5-bar coverage throughout their facility.

A flexible solution that worked for their 5,000 employees and will continue to provide coverage as the company grows and evolves.
