Deploying a Distributed Antenna System (DAS) or a Neutral Host Network (NHN) isn’t just about installing hardware and flipping a switch.
It’s a strategic, technical, and logistical puzzle that, if not approached correctly, can result in delays, overspending, poor coverage, and unhappy stakeholders.
Whether you’re a building owner, facilities manager, developer, or IT decision-maker, avoiding the most common pitfalls is crucial to ensuring a successful deployment that performs as intended.
Let’s dive into the 10 most common mistakes we see in DAS and NHN deployments, and how you can dodge them like a pro.
1. Not Starting with a Proper RF Site Survey
The mistake:
Jumping into design or equipment selection without a comprehensive Radio Frequency (RF) survey.
Why it matters:
Every building is unique in its materials, layout, and RF challenges. Without real data, you’re designing blind.
How to avoid it:
Engage a qualified RF engineer to perform a full spectrum analysis, identifying dead zones, interference sources, and propagation issues. This is the foundation of everything.
Pro tip:
Don’t settle for a basic walkthrough. Use tools like spectrum analyzers, signal scanners, and heatmap software.
2. Treating DAS Like Wi-Fi
The mistake:
Assuming DAS can be designed and installed like a Wi-Fi network.
Why it matters:
DAS and Wi-Fi serve different purposes and operate on different frequencies, power levels, and infrastructure models.
Wi-Fi is user-managed and unlicensed. DAS involves carrier signals, licensing, and often regulatory compliance.
How to avoid it:
Work with DAS-specific integrators who understand the nuances of signal propagation, multi-operator support, and RF compliance.
3. Failing to Involve Carriers Early
The mistake:
Designing your system without input or approval from the wireless carriers you intend to support.
Why it matters:
Each Mobile Network Operator (MNO) has its own frequency bands, signal strength requirements, and integration procedures. If they don’t sign off, your system could be rejected or underutilized.
How to avoid it:
Engage carriers early. Share your building plans, expected user loads, and timeline. Get Letters of Intent (LOIs) from them if possible. This ensures their requirements are baked into the design from day one.
4. Underestimating Backhaul Requirements
The mistake:
Assuming your current fiber or internet setup will support the new DAS or NHN traffic.
Why it matters:
DAS and NHNs, especially 5G-ready ones, demand significant bandwidth, low latency, and resilient connections to the core network. Inadequate backhaul = poor performance.
How to avoid it:
Plan for dedicated fiber uplinks and consider redundancy options. Work with your ISP or neutral host provider to build a backhaul strategy that scales with your traffic demands.
5. Choosing the Wrong DAS Architecture
The mistake:
Deploying passive DAS when you need active. Or choosing a proprietary solution that can’t scale or interoperate.
Why it matters:
Not all DAS architectures are created equal. The wrong choice can lead to limited coverage, poor signal quality, or expensive rework later.
How to avoid it:
Evaluate your:
- Building size and layout
- User density
- Bandwidth demands
- Multi-operator requirements
Work with a vendor that can provide modular and scalable DAS platforms, and avoid vendor lock-in.
6. Ignoring Aesthetics and Access
The mistake:
Designing the network without considering where antennas, cabling, or equipment will be installed visually.
Why it matters:
Architects and tenants care about how things look. Building management cares about where maintenance teams can access gear. Ugly installs or blocked access can cause real headaches.
How to avoid it:
Coordinate early with:
- Architects
- Facilities teams
- Property managers
Use low-profile or ceiling-integrated antennas and ensure equipment rooms are accessible but secure.
7. Skipping Permitting and Code Compliance
The mistake:
Assuming you don’t need permits or approvals for indoor DAS or NHN work.
Why it matters:
Many local authorities require permits, fire code compliance, or safety inspections, especially if you’re modifying risers, power systems, or RF transmission components.
How to avoid it:
Consult a DAS integrator who is familiar with AHJ (Authority Having Jurisdiction) requirements in your area. Budget time for inspection approvals and plan accordingly.
8. Neglecting Power and Battery Backup Planning
The mistake:
Forgetting to account for power distribution and failover systems for your DAS/NHN equipment.
Why it matters:
If the power goes out, your wireless connectivity shouldn’t. Without backup power, your system becomes unreliable during emergencies.
How to avoid it:
Plan for:
- Uninterruptible Power Supplies (UPS)
- Generators for extended outages
- Separate dedicated circuits for DAS equipment
Some jurisdictions even require battery backup for life-safety reasons (especially for public safety DAS).
9. Poor Documentation and Labeling
The mistake:
Leaving behind a system with no maps, cable IDs, or troubleshooting guides.
Why it matters:
When something goes wrong or an upgrade is needed, a lack of documentation makes it nearly impossible to diagnose or expand the system efficiently.
How to avoid it:
Demand as-builts, RF test reports, wiring diagrams, and a digital asset management plan from your installer. Label everything clearly and maintain version control.
10. Forgetting About Ongoing Maintenance and Monitoring
The mistake:
Treating DAS or NHN as a “set it and forget it” solution.
Why it matters:
Over time, networks evolve. Carrier frequencies change. Equipment ages. Without proactive monitoring, small issues can turn into major outages.
How to avoid it:
Partner with a service provider that offers:
- 24/7 remote monitoring
- Preventative maintenance
- SLA-backed support contracts
This ensures your network stays optimized and aligned with carrier updates.
Bonus Mistake: Trying to DIY Your Deployment
Yes, we’ve seen it. Someone downloads a DAS planning app, buys a signal booster kit, and hopes for the best. Spoiler: it doesn’t work like that.
There’s real RF engineering, carrier coordination, and compliance involved. Cutting corners here almost always leads to regrets.
Final Thoughts
Deploying a DAS or Neutral Host Network is one of the most strategic technology decisions you can make for your building. Get it right, and you’ll deliver flawless wireless coverage, happy tenants, and long-term value.
Get it wrong… and you could face costly rework, unhappy users, or a system that carriers simply refuse to activate.
But now you know what to avoid.
