The frequency band from 4940-4990 MHz has been assigned by the FCC for Public Safety applications. Commonly referred to as the 4.9 GHz band this FCC allocation provides municipalities the opportunity to obtain licensed spectrum for the deployment of broadband wireless networks designed to improve and streamline the effectiveness of local government agencies in the pursuit of public safety. Doodle Labs’ FCC certified 4.9 GHz Public Safety Band transceivers allow the System Integrators to develop modems and routers to meet cost and performance requirements.
The FCC rules allow for mobile and fixed services, and both Point-to-Point (PtP) and Point-to-Multipoint (PtMP) topologies are permitted for carrying voice, data, or video traffic. The spectrum cannot be used for commercial, i.e. revenue-producing, services. Qualified agencies can easily acquire licenses online through the FCC Universal Licensing System.
A wireless broadband network in the licensed 4.9 GHz frequency band meets the challenges for a citywide public safety applications. A well designed wireless broadband network can address multiple public safety and municipal agency requirements. In most cases, capacity and coverage will be sufficient with a common network to address additional multiple public service applications. High-quality broadband communications between citywide stationary and mobile units with centralized control are essential and intra-agency communications enhance the municipality’s ability to combat crime, respond to natural disasters or major accidents, and protect critical infrastructure. A wireless broadband network can support a wide range of applications and citywide services that fall under the umbrella of public safety. Typical applications include:
- Law Enforcement and First Responders:
Video surveillance for crime prevention and suspect identification and apprehension
Field connectivity for timely and secure communications with central office for location-based information and coordinated incident response
- Intelligent Traffic Systems:
Traffic monitoring and centralized control for traffic lights
Timely driver alerts for changing road conditions and potential hazards for accident prevention
- Public Transit Systems:
Fleet management with data collection
- Medical Services:
Video, data, and voice access from the field to central command in administering aid to the injured
- Fire Protection Services:
Vehicular installed WiFi hot spot to provide video images to centralized command center
- Critical Infrastructure Protection:
Video surveillance and monitoring for streets, public areas, and critical facilities such as seaports, airports, train stations, sports stadiums, special events, etc.
The large amount of network traffic resulting from these wide range of applications can be managed and prioritized so that emergency-related communications take precedence over non-emergency traffic.
The FCC allocation of 50 MHz of spectrum in the 4.9 GHz band provides eligible municipalities and government agencies the opportunity to deploy a licensed broadband network for enhanced capability in addressing citywide public safety requirements. Doodle Labs’ FCC certified 4.9 GHz Public Safety Band transceivers allow System Integrators to develop modems and routers to meet the cost and performance requirements.
