If tenants or employees are complaining about dropped calls and slow loading speeds, your building likely has poor cellular coverage. The good news? There are solutions, and we can help.
Why Is My Building’s Signal Weak?
Common causes include building materials (concrete, metal, Low-E glass) that block RF signals, distance from cell towers, and network congestion. Fixing it requires the proper in-building wireless infrastructure retrofitted to your building.
Steps to Improve Cell Phone Coverage:
1. Understand your Needs and Budget
There is no one-size-fits-all solution in the wireless industry. Identifying your building’s use case and tailoring the solution helps align your budget with expectations from the start.
2. Signal Assessment
Always start with a benchmark assessment of the existing macro signal. A professional site survey will identify coverage gaps and will help determine the best solution for your building.
3. Choosing the Right Solution
Not all solutions are right for every building or budget. Options range from carrier-independent systems like Part 20 solutions, which expedite deployment, to carrier-coordinated systems such as Class-A solutions for extensive coverage.
Having industry experts guide you ensures you avoid cookie-cutter approaches and implement the right system for your needs.
Why You Should Invest in Better Coverage
Tenant satisfaction is directly linked to reliable mobile connectivity. According to industry surveys:
· 60% of building managers report tenant complaints aboutLTE voice and data quality
· Over 80% say prospective tenants ask about mobile service during evaluations. Enhancing in-building cellular coverage not only improves tenant experience but also boosts property value.

If you're planning an in-building wireless project or Distributed Antenna System (DAS) installation, ensuring proper coverage, FCC compliance, and seamless integration is critical. Avoiding common pitfalls can save time, money, and frustration. Here are five major mistakes to steer clear of:
1. Skipping a Signal Assessment
One of the biggest mistakes is not conducting a professional benchmark survey before starting your project. A macro benchmark test:
· Identifies existing signal strength
· Ensures engineering is sound all the way through
· Provides necessary information for designing the right wireless coverage system for your use case within your budget constraints.
· Shows the improvement of your investment before and after installation.
Without a signal assessment, you risk blind spots, interference, and ineffective coverage solutions.
2. Not defining your budget upfront
Before DAS engineering begins, you need to define your budget and capacity/coverage goals. This will help the engineers understand your needs and how to achieve them. Wireless solutions and combinations are infinite, and your budget will determine the best signal source and system type for your project.
3. Overlooking Carrier Integration
A Distributed Antenna System (DAS) is useless without proper carrier integration. Some projects fail because they lack carrier approvals, leading to weak signals even after expensive deployments. Carrier coordination is critical for:
- OEM equipment compatibility
- Meeting FCC compliance
- Avoiding costly legal implications
4. Poor Installation Practices
Improper DAS installation can derail your entire project. Common mistakes include:
· Incorrect connectorization and fiber splicing
· Failure to optimize and tune the system properly
· Lack of certification and training for installers
A properly installed DAS eliminates delays, reduces troubleshooting headaches, and ensures maximum performance and reliability from day one.
5. Choosing the Wrong Integrator
Not all in-building wireless contractors are created equal. The right partner will:
· Have RF engineering experience
· Have technicians who know the RF and how to tune thesystem properly
· Understand the Commissioning and acceptance
· Verify the system is working at optimum performance
Get It Right the First Time
Avoiding these mistakes will ensure a successful in-building wireless deployment and enhance cellular coverage. Work with experienced wireless contractors, DAS providers, and wireless carrier integration specialists to build a system that meets your needs.

As emergency communication requirements tighten across the country, building owners, developers, and facility managers need to stay ahead of ERRCS compliance to avoid costly setbacks and ensure public safety for tenants and first responders.
This guide answers the most pressing questions around Emergency Responder Radio Communication Systems (ERRCS), code enforcement, and how to stay compliant.
1. Why Are Cities Increasing Enforcement?
Across the country, cities are putting more emphasis on in-building wireless communication for one simple reason: first responders need reliable radio coverage in emergencies.
Poor signal coverage inside buildings can delay emergency response and endanger both responders and occupants. This risk has led many jurisdictions to update fire code enforcement and accelerate inspections for ERRCS compliance.
2. What Are Cities Requiring?
Newer construction methods and materials—such as Low-E glass, reinforced concrete, and energy-efficient insulation—can block or degrade emergency radio signals. That’s why Authorities Having Jurisdiction (AHJs) are increasingly requiring ERRCS systems and ongoing testing.
Typical requirements include:
- ERRCS for new and existing commercial buildings
- Pre-construction radio frequency (RF) surveys
- Annual testing and re-certification
- Full documentation to receive a Certificate of Occupancy (CO)
- Use of UL 2524-listed equipment and compliance with NFPA 1225 and IFC Section 510
3. Which Cities Are Enforcing ERRCS?
Enforcement is expanding nationwide, particularly in metro areas where public safety departments have adopted newer fire codes.
Below is a map showing where ERRCS are being mandated across the country:
Each jurisdiction has its own set of codes, making it imperative that your ERRCS engineer and contractor thoroughly understand your jurisdiction. A few of the nuances are listed here:
Atlanta, GA
All new commercial construction must meet IFC Section 510 and demonstrate in-building radio coverage. COs will not be issued without ERRCS approval.
Seattle, WA & Oregon State
Structures over 50,000 square feet must ensure reliable radio communication or install a code-compliant ERRCS system.
San Francisco, CA
ERRCS is required under Fire Code Section 511 for most commercial, high-rise, and underground buildings. The San Francisco Fire Department must inspect and approve systems before occupancy.
4. What Happens if My Building Is Not in Compliance?
Failing to meet ERRCS requirements can result in:
- Delays in obtaining your Certificate of Occupancy (CO)
- Fines and code violations
- Risk to life safety in emergencies
- Expensive retrofits and construction delays
- Failed inspections and additional permitting headaches
5. How Do I Maintain Compliance?
Staying compliant requires more than a one-time install. Here’s how to stay on track:
- Conduct a Signal Survey – Assess your current coverage.
- Install a Code-Compliant ERRCS – Use UL 2524-certified equipment.
- Perform Annual Testing – Required by most AHJs.
- Maintain Documentation – Keep test reports, drawings, and maintenance records accessible.
