When Lives Are on the Line: Why Hospitals Are Racing to Fix Their Cellular Coverage Problem
Part 1 of a 2-Part Series on Hospital Connectivity
Hospitals are designed to save lives — but many struggle with a critical infrastructure problem: reliable cellular connectivity inside their buildings.
As healthcare becomes increasingly mobile and digital, poor cellular coverage in hospitals can affect patient care, staff communication, and hospital operations.
In this two-part interview series, Justin Green, National Sales Director for Healthcare, shares insights from years of working with healthcare systems to address one of the industry's most overlooked challenges: in-building cellular coverage.
Part 1 explores why hospitals struggle with connectivity and why healthcare organizations are investing heavily in wireless infrastructure upgrades.
Key Takeaways
Many hospitals have poor cellular coverage inside buildings due to construction materials that block wireless signals.
Reliable connectivity is critical for electronic health records, communication, and mobile clinical workflows.
Wi-Fi alone cannot support the growing number of mobile healthcare devices.
Hospitals are increasingly investing in in-building wireless infrastructure to solve connectivity challenges.
When Connectivity Fails, Patients Feel It
Imagine a mother sitting in a neonatal intensive care unit (NICU) while her premature baby fights for life in an incubator.
Her family is hundreds of miles away and desperate for updates. She pulls out her phone to video call them — but there’s no signal.
She faces a painful choice: leave her baby’s side to find cellular coverage outside, or stay and remain disconnected from her support system.
Situations like this happen every day in hospitals across the United States.
According to Justin Green, these moments highlight how critical connectivity has become in modern healthcare.
“Healthcare has a profound, widespread business problem,” Green explains. “The provision of care is made more difficult without good connectivity.”
The Hidden Hospital Connectivity Problem
Hospitals rely on wireless communication more than ever before.
Doctors, nurses, and support staff depend on mobile devices to:
access electronic health records (EHR)
communicate across departments
receive patient alerts
coordinate care teams
locate equipment and staff
When cellular coverage fails inside the building, these workflows slow down or break entirely. To solve these challenges, many healthcare facilities eventually turn to in-building wireless systems such as Distributed Antenna Systems (DAS) that extend cellular coverage throughout the building.
Green notes that hospital leadership quickly responds when physicians report connectivity problems.
“If doctors complain, that’s seen as lives on the line by the higher-ups,” he says.
Because of this urgency, healthcare has become one of the fastest-growing sectors investing in in-building wireless infrastructure.
Why Cellular Coverage in Hospitals Is Often Poor
Hospitals often have poor cell signal because building materials such as reinforced concrete, steel framing, and energy-efficient glass block radio signals from entering the building. These materials weaken signals from nearby cell towers, making it difficult for mobile devices to connect indoors.
Healthcare facilities are particularly challenging environments for wireless connectivity because they are constructed using materials designed for durability, safety, and energy efficiency.
Common causes of poor indoor cellular coverage include:
reinforced concrete walls
steel structural framing
energy-efficient low-emissivity glass
large building footprints and dense layouts
These materials can create what engineers describe as a Faraday cage effect, preventing cellular signals from penetrating the building.
Even hospitals located near strong outdoor cell towers frequently experience poor indoor coverage. As a result, patients and healthcare staff may have strong signal outside the hospital but lose connectivity immediately after entering the facility.
Many healthcare organizations address these challenges by deploying in-building wireless infrastructure such as Distributed Antenna Systems (DAS) that bring cellular signal indoors.
Why Wi-Fi Alone Isn’t Enough
Many hospitals attempted to solve connectivity problems by expanding Wi-Fi coverage throughout their facilities.
However, Wi-Fi networks were not designed to handle the level of mobility required in modern healthcare environments.
Green explains that hospitals frequently encounter performance issues when relying solely on Wi-Fi.
“The general consensus is that voice stinks — not just on your cell phone, but even on Wi-Fi phones,” he says.
Healthcare facilities also face strict privacy and compliance requirements under HIPAA regulations. Cellular networks provide advantages such as carrier-grade authentication and encryption.
Because of these limitations, hospitals increasingly rely on both Wi-Fi and cellular infrastructure to support modern clinical workflows. Many hospitals are now supplementing Wi-Fi with dedicated cellular infrastructure designed for healthcare environments.
A Growing Infrastructure Investment
As mobile technology becomes central to healthcare delivery, hospitals are investing heavily in connectivity infrastructure.
Many healthcare systems are funding multi-million-dollar projects to deploy in-building cellular systems that ensure reliable coverage throughout their facilities.
These systems help support:
mobile clinical workflows
secure communication between care teams
connected medical devices
patient and visitor connectivity
telehealth and digital health services
But solving hospital connectivity challenges requires more than simply installing antennas or equipment.
Hospitals must design wireless infrastructure that works within complex building environments while meeting strict regulatory and operational requirements.
Improving Connectivity in Healthcare Environments
Reliable wireless connectivity has become a foundational requirement for modern hospitals. From mobile clinical workflows to connected medical devices, healthcare organizations increasingly depend on resilient wireless infrastructure.
If your healthcare facility is experiencing connectivity challenges, modern in-building wireless infrastructure can improve reliability, communication, and patient care outcomes.

From Small Clinics to Major Medical Centers
Connectivity challenges affect healthcare facilities of all sizes.
Green has worked on projects ranging from small emergency facilities — sometimes called “doc-in-a-box” sites — to the largest hospital systems in the country.
These smaller emergency facilities often serve as the first step in expanding healthcare services into new regions.
“They build a ton of those because they’re profitable,” Green explains. “They start with an ER, and eventually that location may expand into a larger medical campus.”
Regardless of facility size, reliable wireless connectivity is becoming a foundational requirement for modern healthcare.
The Economics of Hospital Connectivity
Historically, wireless carriers sometimes funded cellular infrastructure projects in hospitals.
That funding model has changed significantly.
“There was certainly a point in time when carriers were helping fund systems in hospitals,” Green explains. “But those days are essentially over.”
Today, hospitals are often responsible for funding their own wireless infrastructure upgrades.
Despite the cost, many healthcare leaders recognize that reliable connectivity is essential to modern healthcare operations.
What Comes Next
Hospitals understand the problem: poor cellular coverage inside healthcare facilities can disrupt communication, slow workflows, and affect patient care.
The next question is how healthcare organizations can solve it.
In Part 2 of this series, we explore the technologies hospitals are deploying to address these connectivity challenges — including distributed antenna systems (DAS), small cells, and private cellular networks designed specifically for healthcare environments.
