Communications

Overview

Communication is the information system.

Every decision you make during a disruption depends on it. Whether to shelter or evacuate. How to treat an injury. Whether your family is accounted for. The quality of every decision traces back to what you know, what you can look up, and who you can reach.

In normal operation, your smartphone handles all three seamlessly. During a disruption it handles none of them reliably, and many households lack a fallback plan.

Communication resilience breaks into three independent capabilities.

The first capability is Situational Awareness - knowing what is happening outside your house. Is the outage localized or regional? Are roads passable? Is the situation stable or developing? Without external information, every decision is made blind.

The second capability is Reference Knowledge - the information physically inside your house when connectivity is gone. Medical dosages. First aid procedures. Evacuation routes. Today almost every practical reference lives on a device that requires power and a network. When those are gone, the information is gone with them.

The third capability is Coordination - reaching the people who need to hear from you. Your spouse. Your kids. Emergency services. Neighbors. Getting information out is how you establish accountability, call for help, and synchronize action across a household that may not be in the same place.

Communication resilience requires all three capabilities to function independently.

Your Communication Independence Score is the lowest of the three.

The Pre-Flight Check scores each capability independently. Doctrine explains the architecture. Field Operations covers the plan.

Failure Modes

Pre-Flight Check

Three capabilities. Three scores. Your Communication Independence Score is the lowest of the three - you are only as independent as your weakest capability. Each gap maps directly to a specific item in the loadout.

Doctrine

Doctrine sequences communication resilience across three independent capabilities.

Situational Awareness

Situational awareness does not disappear instantly during a disruption. It collapses rung by rung as infrastructure fails. Understanding that sequence tells you exactly what to build.

The ladder below assumes the household retains enough power to operate the equipment listed. NOAA weather radio is the exception - it operates on battery backup independent of household power.

Most households are fully covered at the top rung and severely degraded by the third. The gap between those two states is what this capability addresses.

NOAA Weather Radio and AM/FM Broadcast

NOAA broadcasts continuously on dedicated frequencies independent of internet infrastructure and cellular networks. When both are down, that signal is typically the last to fail. It carries weather alerts, evacuation orders, shelter-in-place notices, and restoration timelines - the information most relevant to household decision-making during a disruption.

Local AM/FM stations provide regional emergency coverage that NOAA does not - road conditions, local shelter locations, utility restoration updates. Many operate on emergency generator backup and stay on air through extended outages. Most quality NOAA units include AM/FM reception, consolidating both capabilities into a single device. Vehicle radios also retain AM/FM access independent of household power and are often the first awareness source people reach during an outage.

A capable unit includes battery backup so it continues operating through a power outage, alert tone activation so it functions as an alarm when you are not actively monitoring it, and SAME county filtering so alerts are geographically relevant. Staging requirements are covered in Field Operations 6.3.3.

Broadcast Television

Over-the-air broadcast signal is independent of cable and internet infrastructure. It requires device power, offers no alert function, and provides broad coverage rather than a dedicated emergency channel. It is a legitimate secondary source when device power is available - not a replacement for dedicated emergency broadcast capability.

Satellite Internet

Satellite internet operates independently of local cable infrastructure and regional cellular networks. When terrestrial connectivity fails, it restores general internet access to the household. It requires device power to operate - factor it into your Energy system calculations. It is not essential for 72-hour capability. For households that require information continuity beyond what NOAA and AM/FM provide, it is the highest-capability residential solution available.

Reference Knowledge

Reference Knowledge is a two-axis problem: what information your household has, and what infrastructure is required to access it. Most households are heavily weighted toward high-value information locked behind maximum infrastructure dependency. When connectivity fails, that information disappears with it.

Printed references are the floor. They are the only format independent of both power and connectivity. Everything above the floor depends on some combination of the two.

Medical Reference

Reliable instructions for common injuries, illness treatment, and medication dosing. When something happens, the answer needs to be in your hands in seconds - not on a screen requiring signal. See the Medical system loadout for the recommended title.

Systems Knowledge

Operating and troubleshooting instructions for your household systems. This manual is the primary systems knowledge reference for EPICS households. It should exist as a PDF on every household device and as a printed copy stored with your emergency supplies.

Navigation and Local Geography

A road atlas covers regional and national navigation. Printed county and local maps cover evacuation routes, shelter locations, and secondary roads that a regional atlas omits. Household-specific rally points and evacuation routes belong in the Records system. The maps belong here.

Offline Digital Library

A loaded drive extends reference capability significantly when household power is available but connectivity is not. A drive without a compatible powered device to read it is not a knowledge resource - factor device availability into your staging plan.

Coordination

Channel independence means each communication path fails differently. Coordination resilience requires building down the stack - each step removes a dependency layer.

Cellular

Voice and text run on the same network infrastructure - two protocols, not two independent channels. Text is meaningfully more resilient under load: messages queue and transmit when capacity is available. Text first is a protocol, not a preference. Cell tower battery backup is typically measured in hours, not days.

Landline

POTS - Plain Old Telephone Service - is the original copper-wire landline. It carries its own power through the line and operates independently of household power and internet infrastructure. Most residential landlines today are VoIP over cable - sharing the same failure mode as your internet connection. True POTS availability is declining as providers migrate to digital systems. Verify what you actually have before counting it as an independent channel.

Two-Way Radio

Two-way radios require no network, no infrastructure, and no subscription. When cellular fails, they work. A radio is defined by the infrastructure it depends on, not the shape of the device.

Push-to-talk over cellular (PoC) radios are a common source of confusion in preparedness circles. They transmit voice over LTE data networks - cellular devices with a push-to-talk interface. When you press the button, your voice travels through the cellular network and internet servers to reach other radios on the same talk group. They only function when cellular towers, carrier networks, and internet backhaul are all operational. Coverage is identical to cell phone coverage. If a phone cannot connect, the PoC radio cannot either. They belong above cellular in the coordination stack, not below it. They are not a backup channel.

HAM radio is not recommended for households in the suburban jungle. It requires passing a licensing exam that most households will not complete. It requires frequency knowledge, antenna setup, and operating discipline to use correctly - equipment that sits on a shelf without practice becomes shelf equipment. And it solves the wrong problem: HAM excels at long-distance communication with strangers. Coordinating with your spouse and children two miles away is a simpler problem. GMRS solves it without the licensing barrier or operational overhead.

GMRS radios operate at higher power than consumer FRS radios, providing better real-world range in suburban environments. They require a household FCC license - no exam, covers the entire household, valid for ten years. Radios used regularly in daily life are radios you know how to operate before they are needed.

Satellite

Satellite messaging and internet operate independently of all terrestrial networks. Failure modes are largely independent of every channel above them in the stack - sky visibility, device battery, and subscription status rather than towers, cables, or carrier infrastructure. Many current smartphones include built-in satellite SOS and messaging capability at no additional hardware cost. Portable satellite internet terminals extend this to full connectivity from any location with open sky.

Doctrine tells you how the system works. Field Operations tells you how to run it.

Field Operations

Doctrine describes the architecture. Field Operations is how you build, maintain, and activate it. Three operational subsections cover configuration, planning, and staging. A maintenance schedule and flight bag summary follow.

Phone Configuration

A smartphone ships unconfigured as an emergency tool. Configuration requirements are simple and take less than fifteen minutes. Do this now for every household member.

Reconfigure all settings after every phone upgrade. A new device does not carry these settings forward automatically.

Battery Discipline

Close background apps, enable low-power mode, reduce brightness, and disable unnecessary notifications. Charge strategically from power banks rather than waiting for the device to die. Check signal at intervals rather than constantly - repeatedly unlocking to check service drains battery faster than almost any other behavior. Airplane mode between check-ins extends life significantly when signal is poor or absent.

Communication Plan

A plan that only one person knows is a single point of failure. Every adult in the household must know the following from memory - not from a phone that may be dead or lost.

These answers belong on a laminated card in every wallet, go-bag, and vehicle. The Section 3 template covers all six fields. Print it, laminate it, distribute it.

Plans degrade. Review after every severe weather alert and after any household change - new member, new vehicle, new address. Quiz the household. If your spouse cannot name the out-of-area contact without checking their phone, the plan has a gap.

Equipment Staging

Weather Radio - Central location accessible to the full household: kitchen, main living area. Not a bedroom, not a basement. The alert function needs to reach everyone. Plug in for primary power, verify battery backup is installed and charged, leave it on at all times.

Radios - Staged where the household naturally reaches for them: front door, hallway, main entry. Not in original packaging, not in a closet. If the radios are used regularly they stage themselves. If they are emergency-only equipment, check charge and verify channel settings as part of the maintenance schedule.

Reference Library - One consolidated location accessible to all household members. Print this manual and store it with your emergency supplies. Save the PDF to every household device and at least one offline drive. Critical procedures and contact information go in go-bags and vehicles.

Satellite Internet - Store with all accessories grouped in a single dedicated case: dish, power cable, and battery bank together. Stage it ready to grab.

Maintenance Schedule

Flight Bag

The Flight Bag is not a prepper concept. It is a grab list - what travels when you leave the house under pressure.

Loadouts

Three tiers. Each is additive - the 7-Day assumes the 72-Hour is complete, and the 14-Day assumes the 7-Day is complete. Communication capability does not scale with household size - a family of four needs the same weather radio as a family of two. The tiers represent capability expansion, not duration scaling.

Services

The loadouts above take a household well beyond 14 days of communication independence without professional involvement. The shift to professional services happens when the architecture needs to be designed and tested correctly the first time - when you want verification, not just equipment.
