Spectrum Intelligence
for Smart Cities

Spectrum Is the Invisible Infrastructure of the Smart City              

Smart city programs are built on wireless. Traffic adaptive signals, public safety cameras, smart lighting, environmental sensors, autonomous transit, emergency communications, and public Wi-Fi all depend on radio spectrum operating reliably in a shared environment. When that spectrum is congested, contested, or unmanaged, the systems built on top of it fail — often without administrators knowing why.

Most cities have invested heavily in smart infrastructure hardware — sensors, controllers, network equipment. Few have invested in the ability to see and manage the RF environment that makes that hardware work. The result is city systems that underperform, require expensive troubleshooting, and compete invisibly with each other and with commercial networks in shared spectrum.

CLEARSITE™ gives cities the spectrum management layer that smart city programs have always needed: continuous, city-wide visibility into the RF environment, with the tools to manage it as the critical utility it is.

Key Challenges

  • Overlapping WiFi, CBRS, public safety, and private networks in dense areas
  • Interference affecting traffic control, video backhaul, or IoT telemetry
  • No common view of RF conditions across agencies and vendors
  • Difficulty assuring quality of service during large events, disasters, or infrastructure failures

The Smart City Spectrum Problem

Overlapping Networks Without a Common RF View

A typical smart city operates dozens of wireless systems across multiple city agencies, vendors, and service providers: public safety radio, CBRS networks, Wi-Fi infrastructure, LoRa IoT sensors, traffic management wireless, school networks, utility mesh, and more. These systems are deployed, managed, and procured independently — with no common view of how they interact in the RF domain.

CLEARSITE™ provides that common view: a city-wide RF intelligence platform that sees all technologies, all frequency bands, and all system interactions simultaneously.

CBRS & Unlicensed Band Congestion

CBRS has become a foundational spectrum resource for smart city deployments. But CBRS is shared spectrum, and as more deployments compete in the same band, interference and coexistence failures become increasingly common. Traffic camera backhaul, private school networks, utility automation, and building management systems may all be operating in CBRS simultaneously — each unaware of the others.

CLEARSITE™ manages CBRS coexistence at the physical layer, identifying conflicts, recommending channel optimizations, and ensuring that priority services maintain quality of service even as the CBRS environment grows more crowded.

IoT at Scale: The Interference Challenge

Smart city IoT deployments — environmental sensors, smart parking, utility monitoring, public safety IoT — operate in unlicensed bands where congestion is already significant and growing. As device counts scale, interference between IoT networks and between IoT and other wireless systems becomes a material performance issue.

CLEARSITE™ provides the RF-layer visibility needed to identify these conflicts and make the channel and power adjustments that restore IoT reliability without requiring vendor-by-vendor investigation.

Large Event RF Management

Large public events — concerts, sporting events, political gatherings, disaster response operations — create sudden, intense RF demand in concentrated areas. Public safety communications, media satellite uplinks, event networks, and the personal devices of large crowds all compete simultaneously. Managing this complexity reactively is nearly impossible.

CLEARSITE™ provides pre-event RF assessment, real-time monitoring during events, and post-event analysis — giving city operations and public safety teams the RF picture they need to plan, manage, and debrief major events.

What CLEARSITE™ Delivers for Smart Cities

  • City-wide RF visibility across multiple frequency bands and wireless technologies
  • CBRS coexistence management: channel optimization and interference resolution
  • IoT network performance monitoring across unlicensed and licensed bands
  • Priority traffic protection: ensuring public safety communications take precedence
  • Pre-event RF assessment and real-time event monitoring
  • Tools to evaluate new deployments before and after installation
  • Analytics to drive long-term “spectrum as a utility” governance models
  • API and dashboard integration with city NOCs and network management platforms

What DGS Delivers

  • Continuous RF monitoring across the airfield, terminal, and perimeter
  • Detection and classification of drone control links and other unauthorized signals
  • RF forensics capabilities for incident reconstruction and investigation
  • RF performance and interference insights to support private 5G, CBRS, and smart airport initiatives
  • Portable kits for fast deployment during special events, construction, or emergencies

A New Model for City Wireless Governance

The cities that lead in smart city performance over the next decade won’t just be the ones that deploy the most devices. They’ll be the ones that manage the wireless environment those devices depend on. Spectrum — like water, power, and roads — is infrastructure. It needs to be measured, maintained, and governed.

CLEARSITE™ gives city leaders and CIOs the platform to do exactly that: to treat wireless as the critical municipal utility it has become, to manage it proactively, and to ensure that the systems built on it perform as they were designed.
