Overview#
Field teams need fast voice, short written updates, and live sensor context in the same mobile workspace. A responder should be able to push to talk with a team, send a tactical message, and watch a receive-only drone or sensor feed without switching between disconnected apps. Mobile Tactical PTT, Chat, and Sensor Feed brings those field communications together.
The module supports real-time push-to-talk, team chat, and receive-only sensor feed screens for mobile responders. It is designed for public safety, search and rescue, event security, border operations, and tactical teams that need lightweight communications in the field while preserving audit, tenant isolation, and operational context.
Key Features#
- Real-Time Push-to-Talk: Field users can join configured talk channels and transmit short operational voice updates.
- Tactical Chat: Team messages remain attached to the mission, incident, or operational channel instead of being lost in consumer messaging tools.
- Receive-Only Sensor Feed: Responders can view authorised live video or sensor context without being able to control the upstream feed.
- Mobile-First Controls: Screens are designed for gloved, one-handed, and high-stress use with clear channel and connection states.
- Tenant and Mission Scoping: Channels, chat rooms, and feeds are scoped to the authorised organisation and operational context.
- Connectivity-Aware Behaviour: The mobile client surfaces clear connection status and recovers safely when network conditions degrade, disconnecting rather than continuing on an untrusted channel.
- Authenticated Channel Handshake: Dispatch, communications, and push-to-talk connections confirm that the server completed the secure authentication handshake before any traffic is trusted, and disconnect immediately if it did not.
- Strict Endpoint and Room Validation: Server-supplied connection paths and room identifiers are validated against strict allow-lists before any channel is opened, and the organisation requested for a dispatch channel is cross-checked against the signed session, with server-side enforcement remaining authoritative.
- Validated Media Paths: Video elements accept only local media sources, never remote or script-bearing addresses, and voice relay servers are filtered against a trusted allow-list before a call is set up; the session is aborted if none survive validation.
- Denial and Anomaly Logging: Connection attempts that fail validation are refused outright, and malformed incoming channel frames are logged with context rather than being silently converted into synthetic events.
Use Cases#
- Search and Rescue Team Coordination: Ground teams use push-to-talk and tactical chat while viewing a receive-only drone feed from the command post.
- Event Security Patrols: Supervisors broadcast instructions, officers acknowledge in chat, and selected users view camera feeds for crowd movement.
- Border Patrol Operations: Mobile units coordinate over a mission channel and monitor remote sensor context without exposing control functions.
- Fireground Support: Command shares live imagery with sector officers while keeping voice updates short and incident-linked.
- Training Exercise: Instructors review field communication timelines and sensor-view access after the exercise.
- Operations on Hostile Networks: Tactical teams working over untrusted or hostile networks get fail-closed channel behaviour instead of silently degraded or spoofable connections, while multi-tenant deployments gain device-side reinforcement of dispatch channel isolation.
Integration#
Mobile tactical communications connect to the responder mobile workspace, incident and mission context, team membership, sensor and camera feeds, audit logging, and access control. The capability complements existing radio and CAD integrations rather than replacing mission-critical radio infrastructure.
Open Standards#
- WebRTC: Real-time media transport supports low-latency browser and mobile audio or video sessions.
- SRTP: Secure real-time media transport protects audio and video streams in transit where WebRTC media is used.
- ICE, STUN, and TURN: Connectivity establishment follows standard WebRTC network traversal mechanisms.
- RFC 6455, WebSocket Protocol: Real-time channel state and chat updates can use persistent full-duplex connections.
- ISO 8601: Message, channel, feed, and audit timestamps use standard date-time formatting.
- OAuth 2.0 and JWT Bearer Token: Authenticated context protects channel membership and feed access.
