Loss of Communications is a news and information topic monitored and covered by: Prepper Watch – AI, Cyber and Digital Technologies
Introduction
Communication is one of the most critical pillars of survival and preparedness. In a crisis scenario—whether it’s a cyberattack, an EMP (Electromagnetic Pulse) event, or government-imposed restrictions on internet access—the ability to exchange information can mean the difference between life and death. A loss of communication would impact everything from emergency coordination and access to vital news to personal safety and resource management. For preppers, ensuring reliable communication methods that are resilient to modern threats is essential for long-term survival.
This blog will explore the potential causes of communication failures, the impact on society and individuals, and the strategies that preppers can use to maintain effective communication in a grid-down or restricted-communication scenario. Whether you’re a homesteader, urban prepper, or part of a mutual assistance group, these strategies will help you stay connected and informed when it matters most.
1 Threats That Could Cause Loss of Communication
Understanding the types of threats that could lead to a communications blackout is the first step in preparing for them. While communication infrastructure is robust in many parts of the world, it remains vulnerable to specific high-impact threats:
- Cyberattacks
- Cyberwarfare is already a reality. Hackers targeting communication infrastructure, including satellites, cell towers, and internet service providers (ISPs), could create large-scale outages.
- A well-executed attack on a key undersea cable or server farm could lead to regional or even global communication failures.
- State-sponsored cyberattacks could target critical infrastructure, including emergency response networks, creating mass confusion.
- Electromagnetic Pulses (EMPs)
- EMPs, whether caused by a nuclear detonation at high altitude or a natural solar storm, can instantly disable most unprotected electronic devices.
- Power grids, communication systems, and digital devices would be affected simultaneously, plunging society into technological darkness.
- Modern digital infrastructure, including satellite communication and cellular networks, is especially vulnerable to EMP damage.
- Government-Restricted Internet and Communication
- In politically unstable situations, governments have been known to restrict or shut down internet access and cellular networks to prevent the spread of information and coordination of protests.
- Even democratic governments might impose communication restrictions during national emergencies or martial law.
- Targeted shutdowns could affect specific apps, social media platforms, or entire service providers.
- Infrastructure Failure
- Natural disasters (hurricanes, earthquakes, floods) and large-scale fires can physically damage infrastructure, cutting off communication channels.
- Overloaded cellular networks during a crisis can lead to congestion, making it impossible to send or receive calls and messages.
2 The Impact of Communication Loss
The sudden loss of communication could create chaos and undermine personal and societal stability:
Emergency Services Disruption
- First responders rely on communication networks to coordinate rescues and medical aid.
- Loss of 911 services would make it difficult for civilians to seek help.
Breakdown of Information Flow
- No access to news updates, emergency broadcasts, or local advisories.
- Increased spread of misinformation and rumors.
Severed Coordination Among Preppers and Communities
- Prepping groups and MAGs (Mutual Assistance Groups) may struggle to coordinate responses without clear communication channels.
- Lack of coordinated security, resource management, and decision-making.
Economic Disruption
- Banking systems and financial transactions depend on communication networks.
- Digital currency and credit/debit systems would become inaccessible.
3 Building a Communication Resilience Plan
Preppers can take specific, actionable steps to reduce vulnerability and maintain communication during a crisis:
3.1. Establish Alternative Communication Methods
Modern communication relies heavily on internet-based platforms and cellular networks, which are vulnerable to all major threats. Preppers need backup methods:
- HAM Radios (Amateur Radio)
- Independent of commercial infrastructure.
- Operates on a wide range of frequencies (HF, VHF, UHF).
- Licensing is required, but training is widely available.
- Repeaters can extend range, but local shortwave is reliable without them.
- CB Radios (Citizens Band)
- No licensing required.
- 40 channels available for personal and group communication.
- Ideal for convoy coordination and short-range tactical communication.
- FRS and GMRS Radios
- Family Radio Service (FRS) is license-free with a short range (1–2 miles).
- General Mobile Radio Service (GMRS) has better range (up to 20 miles) but requires a license.
- Good for small group communication.
- MURS (Multi-Use Radio Service)
- No license required.
- Better range and penetration than FRS/GMRS.
3.2 Secure Long-Range Communication
- Satellite Phones
- Can function independently of ground-based infrastructure.
- Expensive, but reliable in remote areas.
- Vulnerable to EMPs, but some models are shielded.
- Shortwave Radio
- Can receive global broadcasts.
- Useful for news, weather updates, and emergency broadcasts.
3.3 Protect Against EMPs
- Faraday Cages
- Store critical communication gear (HAM radios, handheld radios, satellite phones) in Faraday cages to shield them from EMPs.
- Faraday bags (portable) can protect smaller devices like walkie-talkies.
3.4 Develop and Memorize Communication Protocols
- Pre-established codes, signals, and frequencies ensure smooth communication if infrastructure is compromised.
- Establish fallback times and channels for regular check-ins.
- Use a mix of signals (whistles, flashlights, hand signals) for short-range tactical communication.
3.5 Use Low-Tech Backup Plans
- Written Communication – Maps, signs, chalk markings, and message boards.
- Signal Fires and Flares – Basic emergency signaling.
- Semaphore and Flags – Simple visual communication for distance signaling.
- Morse Code – Can be transmitted using light, sound, or tapping.
4 Building a Communications Network
Preppers should not operate in isolation—establishing a resilient communications network increases chances of survival:
Mutual Assistance Groups (MAGs)
- Establish local and regional MAGs with HAM or CB capabilities.
- Coordinate drills to test communication readiness.
- Develop leadership roles and secure channels.
Mesh Networks
- Decentralized networks using off-grid routers and repeaters.
- Can operate without internet or cellular infrastructure.
- Ideal for creating local communication grids.
Rural and Remote Solutions
- Install personal repeaters to extend radio range.
- Use long-range directional antennas for HF bands.
- Satellite-based text messaging services like Garmin inReach.
5 Training and Drills
Having equipment is not enough—preppers need to be proficient in using it:
- Regularly test all communication gear.
- Run drills to simulate cyberattacks and EMP events.
- Train family members and team members to use radio equipment and recognize signals.
- Test communication range and clarity under different weather and terrain conditions.
6 Challenges and Limitations
Despite thorough preparation, communication challenges may still arise:
- Limited Range – Handheld radios may not work across long distances.
- Frequency Congestion – Popular frequencies could become overcrowded.
- Interference – Natural obstacles (mountains, trees) and weather can affect signals.
- Power Supply – Communication devices need battery backups and solar chargers.
Conclusion
Loss of communication is one of the most dangerous scenarios for a prepper. Without the ability to gather intelligence, coordinate with others, or receive emergency instructions, survival becomes significantly more challenging. By establishing multiple communication methods—ranging from HAM radios and satellite phones to low-tech signaling—preppers can reduce vulnerability and maintain situational awareness even in the most challenging circumstances.
Preparedness isn’t just about storing food and water—it’s about ensuring you can stay informed and connected when the world goes dark.
