5G Regulatory Policy and Spectrum Sharing Summary

Core Content

This document outlines the regulatory considerations and spectrum sharing implications for the deployment of 5G networks, with a focus on their role in supporting emergency services, wireless emergency alerts, and earthquake early warning systems. It also touches upon other public services such as public safety communications, support for individuals with disabilities, and lawful surveillance.

Main Points

1. Regulatory Requirements for Emergency Services

5G networks must support a range of emergency communication services, including:

• Emergency Voice Calls: These must be prioritized and routed to the appropriate Public Safety Answering Point (PSAP), with location information being crucial for dispatching emergency services.
• Real-Time Text (RTT): This enables bi-directional, character-by-character communication, which is particularly useful for individuals with hearing or speech impairments.
• SMS to Emergency Services: Asynchronous text-based communication that may lack location determination, requiring PSAPs to ask for the caller's location explicitly.

The document emphasizes that 5G must support both voice and text communications with emergency services, regardless of the device's service initialization status.

2. 5G Requirements for Wireless Emergency Alerts (WEA)

5G must comply with all WEA regulatory requirements, including:

• Text Message Size: Increased from 90 to 360 characters for LTE and beyond.
• Multilingual Support: Spanish and other languages may be required, especially in areas where less than 50% of the population speaks English "very well."
• Multimedia Alerting: Potential inclusion of images, hazard symbols, and other media to accompany text alerts.
• Geo-Targeting: The ability to match the broadcast area to the target area specified by the alert originator, ensuring precise delivery to affected regions.

3. 5G Support for Earthquake Early Warning Systems (EEWS)

EEWS leverages broadcast capabilities to deliver early warnings of earthquakes via mobile devices. Key aspects include:

• Broadcast Notification: Utilizing LTE control channels and 3GPP-defined cell broadcast capabilities.
• Geo-Targeting: Mobile devices must determine if they are within the target area, requiring accurate indoor and outdoor location information.
• EEWS Integration: 5G networks will need to support the broadcast of both polygon coordinates and alert messages, with the ability to prioritize alerts based on the predominant language in the alert area.

4. Spectrum Sharing

Shared spectrum is essential for 5G deployment and innovation. It enables:

• Network Expansion: Additional spectrum access for non-traditional operators, such as those deploying networks in single facilities.
• New Network Innovations: Leveraging shared spectrum to support new 5G services and features, including vehicle-to-vehicle (V2V) communication and IoT applications.
• Foundation for 5G: Experience from 4G LTE spectrum sharing will inform and support 5G spectrum strategies.

Key Implications for 5G

• Speed, Capacity, and Reliability: These three attributes are critical for enabling faster emergency response, better multimedia support, and real-time data delivery.
• Device Capabilities: 5G devices must be capable of supporting various communication modes, including RTT and SMS, and must be able to handle geo-targeting and location-based services.
• Standards Development: Ongoing work in 3GPP and ATIS to develop enhanced WEA (eWEA) standards will ensure compliance with new FCC regulations.

Additional Considerations

• Connected Vehicles: 5G can enable connected cars to autonomously contact emergency services based on sensor data, improving road safety.
• Public Safety and Accessibility: 5G must support services for individuals with disabilities, such as real-time text, to ensure inclusive emergency communication.
• Lawful Surveillance: 5G networks must support surveillance and monitoring functions as required by law.

Conclusion and Recommendations

• 5G networks must be designed to meet evolving regulatory standards for emergency communications.
• The industry should collaborate with regulatory bodies like the FCC to identify and address standards gaps.
• Spectrum sharing is a key enabler for 5G deployment, particularly for new and non-traditional operators.

Summary of Key Requirements

• 5G must support all existing and new emergency communication services.
• WEA enhancements, such as increased text size and multilingual support, require updated 5G standards.
• EEWS must integrate with 5G networks for real-time, geo-targeted earthquake alerts.
• Spectrum sharing is a foundational element for 5G expansion and innovation.
