CERT is about doing the most good for the most people. During a worst case scenario deployment one of the symptoms of ineffective management and leadership is poor communication. That is the purpose for the Incident Command System requiring regular organized briefings. A common problem is finding an effective means of communicating over large distances.
- In Person briefings and meetings.
- Sneakernet / Runners
- AMATEUR (HAM) RADIO VHF/UHF
- AMATEUR (HAM) RADIO HF
- Internet (Email, chat, facebook ...etc)
- Localized wireless mesh network (Broadband Hamnet)
- Mobile (Cell) phones
- POTS (Plain old telephone service)
- Satellite telephone/internet
- Public Safety Radio
- Business Band radio
- Commercial broadcast radio
Phases in a disaster deployment
- Preparation - Training and Staging resources
- Response - Resolve immediate threats
- Recovery - Repair damage and restore community back as close as possible to a pre disaster state.
Types of Communication
- 2 way Broadcast channels (2 way radio, Ham, Public safety ...etc)
- 1 way broadcast channels (Commercial broadcast radio)
- 2 way direct channels (Mobile (Cell) phone, POTS, Satellite Phone)
- Multi-user, multi-channel communication (Hamnet, Internet, text messages, conference telephone calls)
- Message based communication (Sneaker-net, Runner, ICS-214 messages)
- Command - Secure, low latency, limited users, 2 way
- Communications fall-back plan.
In the event of a technical failure, a fallback communications method must be identified.
Often this is designating a team of people to be runners. If one radio frequency becomes un-usable then traffic needs to be redirected to another one, if that one fails then it needs to be redirected to another one and so forth.
