5G Regulatory Policy Considerations and Spectrum Sharing Summary

Core Content

This white paper explores the regulatory and technical considerations for the deployment of 5G networks, with a focus on their role in supporting emergency services and public safety. It also highlights the importance of shared spectrum in enabling 5G innovations and widespread adoption.

Main Points

Regulatory Considerations for Emergency Services

5G networks must support various emergency communication methods, including:

• Voice emergency calls: Must be recognized and prioritized by the network, with location determination and routing to the appropriate Public Safety Answering Point (PSAP).
• Real-Time Text (RTT): Enables bi-directional, character-by-character communication for individuals with disabilities or in noisy environments.
• SMS to emergency services: Provides asynchronous text communication, though it lacks location determination, requiring PSAPs to ask for the user's location.

These capabilities are essential for Next Gen 911 (NG9-1-1), which supports multimedia emergency communications.

5G Requirements for Emergency Communications

• Compliance with FCC regulations: 5G must adhere to the FCC's emergency service requirements.
• Support for multimedia: Includes voice, text, video, audio, and graphical content.
• Location determination: Enables accurate routing of emergency calls and the calculation of a dispatchable address.
• Support for non-service initialized (NSI) devices: Emergency calls from devices without a SIM card, expired pre-paid devices, or 911-only devices must be supported.

Implications of 5G for Emergency Services

• The connected car is an example of a 5G IoT device that can autonomously alert emergency services in case of an accident, providing critical information like location and vehicle status.
• 5G must support new emergency scenarios and ensure that services and devices have the potential to save lives and property.

Wireless Emergency Alerts (WEA)

WEA is a system that broadcasts emergency alerts to WEA-capable mobile devices. It includes:

• Presidential alerts, AMBER alerts, and imminent threat alerts (e.g., tornadoes).
• The WEA system is part of the Integrated Public Alert and Warning System (IPAWS), managed by FEMA.
• WEA messages are broadcast using cell broadcast service (CBS) on 2G/3G networks and public warning system (PWS) on 4G LTE networks.

WEA Enhancements

The FCC has proposed several enhancements to WEA, including:

• Increased message size: From 90 to 360 characters for LTE and beyond.
• Multilingual alerts: Spanish and other languages, with potential prioritization based on community language usage.
• Multimedia alerts: Including images and hazard symbols for evacuation routes, missing persons, and protective actions.
• Geo-targeting: Ensuring that WEA messages are sent to the exact geographic area specified by the alert originator, with no more than a 0.1-mile overshoot.

5G Requirements for WEA

• 5G must support text broadcasting similar to 2G/3G CBS or 4G SIB12.
• It must also support future WEA regulations, including multimedia and multilingual alerts.
• Dual-mode devices must monitor 4G LTE control channels for WEA messages even when connected to 5G.

Spectrum Sharing

Shared spectrum is critical for 5G deployment and innovation. Key points include:

• Expanded capacity: Shared spectrum allows for greater network expansion and meets user expectations for speed and capacity.
• Support for new operators: Enables deployment in single facilities like malls, factories, and refineries.
• Experience from 4G: Provides a foundation for 5G spectrum sharing strategies.

Conclusion

The regulatory and technical requirements for 5G in supporting emergency services and public safety are extensive and evolving. 5G's enhanced speed, capacity, and reliability will transform emergency communication, enabling new services like multimedia alerts and real-time data sharing. Spectrum sharing is essential to achieving these capabilities and will be a key enabler for future 5G innovations. The industry must collaborate with regulatory bodies like the FCC to identify and address standards gaps and ensure compliance with emerging 5G regulations.
