Private Off-Grid Communications
Stay connected when networks fail — secure, decentralised communication for critical situations.
When mobile networks go down — through natural disaster, power failure, government restriction, or hostile action — reliable communication becomes the lifeline. CDEC’s Private Off-Grid Communications systems use Meshtastic, an open-source mesh-networking protocol, to deliver secure, low-power messaging even without Wi-Fi, mobile signal, or internet access.
Designed for emergencies, remote operations, expeditions, and high-risk environments, our systems create resilient, independent networks that function when traditional infrastructure collapses. Whether you need credit-card-sized personal nodes or vehicle- or building-mounted base stations, we supply, configure, and train your team for real-world use.
This capability integrates naturally with Secure Mobile Handsets & Hardened Communications, Cyber Security Advisory, and High-Risk Client Protection programmes — providing continuity of command and communication in both routine and crisis operations.
What Makes Us Different
Custom Hardware Options
From pocket-sized personal devices to vehicle-mounted relays and solar-powered base stations, we deliver complete mesh node ecosystems tailored to your operational profile.Offline by Design
No SIMs, no mobile networks, no cloud dependency — just encrypted, peer-to-peer communication that cannot be disabled remotely.Training Included
We don’t just ship hardware. We train your team to deploy, maintain, and operate their network confidently — including QR-based pairing, key management, encryption verification, and range optimisation.Mission-Ready Builds
Every node is pre-configured, tested and hardened for the intended environment, featuring extended battery life, covert housings, and optional solar integration.
Where additional RF or situational assurance is required, our engineers can integrate TSCM Bug Sweeps and Physical, Electronic & Aerial Surveillance packages to validate spectrum cleanliness before deployment.
Client Benefits
Stay Connected When It Counts
Maintain secure communications during blackouts, disasters, or hostile surveillance conditions.Privacy Without Infrastructure
Operate free from cellular providers or external gateways — complete autonomy and encryption control.Scalable Coverage
Create one-to-one, team-wide, or regional mesh networks that expand as new nodes come online.Portable or Fixed Deployment
Combine wearable or vehicle nodes with fixed base systems for tiered, redundant communication capability.
Off-grid networks also integrate with Threat Intelligence & Resilience and Greyzone Threat Resilience programmes to support continuity planning and hybrid-warfare readiness.
