Fueling Better Signal in the Energy Industry
USA Air Liquide is a world leader in gases, technology, and services for energy, petrochemical, industrial, electronic, and healthcare markets. The La Porte, TX facility produces gaseous hydrogen and steam-generated electrical power. It’s Air Liquide’s largest hydrogen production facility in the United States.
THE PROBLEM
Poor Cell Signal Even with A Signal Booster Already Installed
Air Liquide already had a cell phone signal booster system in place. Having poor in-building cellular reception was compromising the hydrogen supply chain as well as workplace safety. The main culprits for this were the building’s construction material and distance from cell towers. Enhanced cellular coverage would improve communication across all channels, productivity, and promote a safer environment.
However, the current system was not delivering strong enough AT&T, Verizon, or T-Mobile signals throughout the 4,000 sq ft building. For those users, it was difficult to make and maintain clear calls, send texts, access business applications, and download/upload files.

THE SOLUTION
Two 50 Ohm Off-Air Passive DASs with Two Donor Antennas Each
A few days after the complimentary consultation, we sent out a team of signal experts to survey the facility. They took signal strength readings, identified potential installation challenges, and inspected the current cell phone signal booster.
Cellular reception outside was below average. Inside, as the customer said, AT&T, Verizon, and T-Mobile connectivity was subpar even with a weBoost Office 200 75 Ohm cell phone signal booster installed.
All of the information gathered was submitted to our design team to customize a new solution that would solve Air Liquide’s concerns within their budget. We proposed two Office 200 50 Ohm units. Using 50 Ohm equipment allows for stronger signal transmission, lower signal loss, and longer cable runs than 75 Ohm equipment. To get the best possible signal inside, each unit was paired with one LPDA antenna and one omnidirectional antenna. A total of 7 low-profile indoor dome antennas would be distributed throughout the building to cover all desired areas with reliable signal.
Once Air Liquide approved the proposal, it took the Bolton Install Pro’s team 2 days to deploy the system without interruptions to daily operation.
THE RESULTS
Dependable Wall-to-Wall Coverage for All Carriers
From start to finish, the custom Off-Air Passive DAS took two weeks to deploy. Through careful placement of all equipment, we managed to get Air Liquide wall-to-wall coverage for AT&T, Verizon, and T-Mobile.
Signal strength improved from –103 to –87 dBm for AT&T, –77 to –61 dBm for Verizon, and -107 to -66 dBm for T-Mobile. This translated to an increase of 2 to 4 bars of service, and in some areas 5.
With reliable cellular reception in every room, Air Liquide is no longer worried about signal dropouts or communication delays, ensuring smooth operations and enhanced safety for all employees.
