The landscape of emergency communications is undergoing a significant transformation, as regional 911 centers integrate advanced cloud technologies to better serve growing and dynamic populations. Nowhere is this evolution more evident than in southeastern Massachusetts, where the Southeastern Massachusetts Regional Emergency Communications Center (SEMRECC) has launched a new cloud-based emergency communication platform using Hexagon’s HxGN OnCall suite, hosted securely on Microsoft Azure. This deployment aims to redefine the speed, scalability, and resilience of public safety communications for a region that not only serves over 200,000 residents across four towns—Easton, Norton, Mansfield, and Foxborough—but also must adapt rapidly to fluctuating security demands from large-scale events and interstate traffic.

Modernizing Emergency Communications in Massachusetts​

For decades, regional 911 centers have contended with legacy systems that are often inflexible, costly to upgrade, and vulnerable to cybersecurity threats. Recognizing these challenges, SEMRECC has taken strategic steps to replace its traditional infrastructure with Hexagon’s HxGN OnCall Dispatch, OnCall Records, and mobile field solutions. This cloud-native environment is designed to optimize operational efficiency, improve data sharing among agencies, and ensure always-on service availability—even when disasters strike or the region’s population temporarily surges.

The Scope and Reach of SEMRECC​

SEMRECC acts as a lifeline for Bristol and Norfolk Counties, encompassing vibrant residential communities and major venues such as Gillette Stadium, home to the New England Patriots, where crowd sizes can balloon by tens of thousands during events. The center is also a critical node in the region’s mutual aid, incident coordination, and acts as the Nationwide Alerting System warning point for all of Bristol County.
The demographic and operational complexity SEMRECC faces demands a level of flexibility that traditional on-premise systems simply cannot deliver. During peak times—such as Patriots game days or emergencies requiring responses across multiple counties—call and data volumes can spike unpredictably. The new cloud-based HxGN OnCall solutions allow for rapid scaling, provisioning more communication channels and computing power precisely when and where it is needed.

Cloud Architecture: Benefits and Strategic Rationale​

SEMRECC’s decision to leverage Microsoft Azure’s secure, resilient cloud infrastructure for Hexagon’s emergency communication platform was influenced by several critical factors:

• Frequent, Automated Upgrades: Cloud-hosted platforms can push automatic software updates and security patches with minimal disruption, guaranteeing the latest features and a robust security posture without labor-intensive manual effort.
• Advanced Cybersecurity: Microsoft Azure’s enterprise-grade security framework provides multi-layered protection—spanning physical data centers, infrastructure, and operational policies—against evolving cyber threats.

Comparing Traditional and Cloud-Based 911 Systems​

Traditional 911 communications systems have generally required heavy up-front investments in hardware, rigid upgrade cycles, and time-consuming maintenance. Furthermore, disaster recovery and business continuity are often weaker, as physical sites can be impacted by local power outages, weather, or other unexpected events.
The Hexagon cloud solution, as deployed by SEMRECC, replaces these with:

• Geo-redundant backup, reducing downtime risk.
• Improved incident response, as mobile field units and back-office teams access the same real-time data.
• Platform-wide event logging and forensics for advanced investigations.
• Streamlined on-boarding of new agencies and response teams as the partnership area expands.

The Technology Stack: HxGN OnCall and Microsoft Azure​

HxGN OnCall Dispatch​

At its core, HxGN OnCall Dispatch provides real-time incident management, resource deployment, and communications with first responders in the field. The cloud-based version enables dispatchers to work from anywhere with secure internet access, a critical capability for continuity during large-scale disruptions or remote staffing requirements.

OnCall Records and Mobile Field Solutions​

Hexagon’s suite extends to OnCall Records, which centralizes all case data, incident histories, and ongoing investigations. Interfacing directly with field mobile solutions, officers can submit reports, access intelligence, and receive dynamic updates without the need to return to station.

The Microsoft Azure Backbone​

Microsoft Azure’s infrastructure hosts SEMRECC’s 911 services, automatically allocating new server resources as call volumes climb or as new towns join the network. This ensures:

• End-to-end encryption of all sensitive data, both at rest and in transit.
• High availability, with industry-leading SLAs for uptime.
• Centralized monitoring and threat detection, leveraging AI-driven analytics.

The Operational Impact: What Changes on the Ground?​

Faster Incident Response​

One of the most direct benefits of SEMRECC’s shift is an expected reduction in response times, particularly during chaotic, high-volume events. Cloud-based solutions facilitate:

• Faster information sharing with fire departments, police agencies, and medical responders—each accessing the same situational intelligence.
• Dynamic rerouting of resources to maintain service levels even during severe weather, major accidents, or infrastructure failures.

Enhanced Mutual Aid and Incident Coordination​

As the regional mutual aid coordinator, SEMRECC must often broker responses between overlapping agencies and neighboring counties. Cloud interoperability ensures that even when agencies use different frontline equipment, they can cooperate through a unified digital platform.

Resilience to Surges and Disruptions​

During major events at Gillette Stadium, for example, SEMRECC’s call volume can double or triple. The Azure-hosted platform’s automatic scaling absorbs these spikes without jeopardizing response times. In scenarios where local outages might cripple traditional systems, geo-redundancy in the cloud ensures that backup centers can take over seamlessly.

Security and Compliance: Meeting the Highest Standards​

Public safety information is among the most sensitive data managed by government organizations. With increasing threats of ransomware, data breaches, and targeted cyberattacks, SEMRECC’s underlying platform must deliver uncompromising security.

Microsoft Azure’s Security Framework​

Azure is recognized for meeting a vast portfolio of global, regional, and industry compliance requirements, including CJIS (Criminal Justice Information Services) standards critical for law enforcement data in the United States. Key security features include:

• Multi-factor authentication for all system access.
• Role-based access controls, ensuring only authorized personnel can interact with specific data sets.
• Continuous penetration testing and threat monitoring.
• Data loss prevention and rapid incident response protocols.
