From Dead Zones to Deep Coverage: Introducing the DAS Deployment Checklist

Reliable indoor cellular connectivity has become the backbone of modern business. Whether you manage a large facility, a hospital, or a high-rise building, your ability to stay connected has a direct impact on productivity, safety, and efficiency.

Yet, many organizations still rely on Wi-Fi calling or conventional mobile networks that were never designed for complex indoor environments.

Dropped or garbled calls, slow data speeds, and E911 compliance gaps are daily frustrations that cost time and money.

For enterprises that cannot afford to be disconnected, Distributed Antenna Systems (DAS) are the engineered solution. These dedicated systems provide the reliability and coverage that traditional systems simply can’t match.

At Metro Wireless, we’ve developed a Distributed Antenna System Discovery Checklist — a practical tool that helps enterprises evaluate their current connectivity challenges and readiness for a DAS.

This blog will walk you through why conventional solutions fall short, how Metro Wireless builds a DAS, and how the checklist can help you take the first step toward a better connectivity future.

For initial DAS discovery, our technical team reviews architectural blueprints, elevation drawings, and any pre-existing network layouts.

Why Wi-Fi Calling and conventional networks fall short

For years, Wi-Fi calling has been seen as a 'substitute' for proper indoor cellular coverage. 

Conventional mobile networks have also improved, but both technologies still share major limitations in large-scale or complex environments.

Businesses often face:

  1. Poor cellular signal inside the facility, even when it's good outside.
  2. Dropped or garbled calls when working inside the building.
  3. Slow cellular data speeds hinder productivity indoors.
  4. Compliance challenges arise because Wi-Fi calling is not E911 compliant and doesn't reliably transmit a caller's location during a 911 call.

These limitations aren’t just frustrating— they’re costly and can create safety risks. That’s why forward-thinking enterprises are shifting to proper DAS solutions that deliver more than just a signal— they deliver reliability.

What makes a Distributed Antenna System (DAS) different

A DAS provides the deep indoor coverage, carrier-grade reliability, and seamless signal consistency that Wi-Fi and conventional mobile networks struggle to deliver. Unlike substitutes, a DAS is:

  1. Engineered for challenging sites to enhance coverage.
  2. Built to extend connectivity where traditional signal falls short.
  3. Carrier-grade in its reliability.
  4. Seamless in its signal consistency.
  5. Capable of providing deep indoor coverage.

In short, a Distributed Antenna System is designed around your building's unique layout and signal challenges.

Ready to Connect? Use This 5-Point DAS Discovery Checklist

This checklist is designed to help enterprises evaluate the need for a Distributed Antenna System (DAS) based on coverage gaps, building specifications, and connectivity demands in complex environments.

1. Is your cellular signal poor inside your facility, yet good when you are outside your facility?

This strong contrast typically indicates that your building's construction materials, such as concrete, metal, or low-E glass, are blocking the signals from outside.

1a. If the cellular signal is poor outside your facility, is it just in certain areas around the building?

Identifying specific external "dead zones" can help determine if the root cause is distance from the nearest cell tower or obstructions like nearby hills or buildings.

2. Do you often have dropped or garbled calls when working inside the building?

Unreliable voice quality is a primary symptom of low signal strength and interference, leading to significant frustration and missed communications.

3. Do you often have slow cellular data speeds when working inside the building?

This problem can severely impact productivity by causing slow-loading emails, lagging video conferences, and difficulty accessing cloud-based apps.

4. Does your industry or line of business require you to be E911 compliant?

Public safety regulations, such as Kari's Law and RAY BAUM's Act, often mandate that enterprises provide accurate location data for 911 calls made from within their buildings.

4a. WiFi calling, a ‘substitute’ for a proper DAS installation, is not E911 compliant as WiFi calling doesn’t reliably transmit the caller’s location during a 911 call.

Relying on this workaround can create a serious liability by failing to give first responders the precise location information they need during an emergency.

5. Do you have $0.75-$1.50 per sq ft of budget to spend on a proper solution?

Knowing this typical cost range helps set realistic expectations for investing in a professional-grade system that fully resolves coverage gaps.

5a. More expensive per foot for smaller buildings, less for larger buildings.

This is because the fixed costs of the core equipment and design are distributed over a smaller footprint, impacting the per-foot price.

Your 6-Point DAS Technical Planning & Data Checklist

Providing detailed site information ensures a precise quote for your Distributed Antenna System (DAS) deployment. Without it, estimates may need to account for unknowns like structural complexity and signal interference. This list incorporates key elements critical to designing a solution that delivers seamless indoor coverage.

1. What is the site address (or addresses)?

This helps us locate nearby cell towers and analyze the external signal environment.

2. Which cellular carriers need enhancement?

Please specify all carriers, such as Verizon, T-Mobile, or AT&T, that are critical for your operations.

3. What is the building layout?

Specify the number of buildings and floors, along with the approximate square footage for each area.

4. What are the ceiling and wall characteristics?

Include details like ceiling type and height (e.g., drop ceiling, open deck) and wall composition (e.g., concrete, drywall) as these materials impact signal.

5. Is there existing fiber infrastructure?

This is especially relevant if multiple buildings or a large campus needs to be served, as it can be used for the system's backbone.

6. What are the usage and timeline expectations?

Include the estimated number of simultaneous users and your desired installation timeline to help us scope the project correctly.

Utilized client-provided floor plans to create an iBwave based DAS design

Our Metro Wireless DAS Discovery Checklist was created to simplify the process of evaluating whether your business is ready for a DAS deployment.

By providing responses and data request items to the Metro Wireless Sales team, you’ll gain clarity on your connectivity needs and provide us with the essential details required to design a network tailored to your building.

Instead of guessing where your network is falling short, the checklist helps you document pain points, building layout, and carrier requirements that shape the right solution.

Our Time-Proven DAS Deployment Process: From Planning to Always-On Connectivity

Building a Distributed Antenna System doesn’t have to be complex. Metro Wireless follows a structured process to design, deploy, and support DAS, ensuring reliable indoor coverage tailored to each building's unique layout and signal challenges.

From site survey to always-on networks in weeks, not months.

  1. Initial Review (3 to 5 days) We start with a floor plan size and space analysis, review building materials, and present a budgetary price estimate.
  2. Site Survey (1 to 2 days) Using iBwave DAS software, our team performs a signal audit, maps cable routes, and creates the final design and antenna placement plan.
  3. Proposal Review & Deployment (5 days for review; 3 to 6 weeks for deployment) We review all equipment and installation costs. Once approved, Metro Wireless provisions and installs the DAS platform, provides all documentation, and conducts testing and customer hand-off.
  4. Ongoing Support: Your DAS journey doesn’t end at deployment. We provide on-going remote monitoring and support to ensure your network delivers reliable coverage.

This end-to-end process ensures your connectivity investment delivers lasting value.
