Planning a MeshCore Community Network
Deploying a MeshCore network for a community requires planning beyond simply placing repeaters - you need to think about coverage, redundancy, operator coordination, and long-term maintenance.
Phase 1: Define Coverage Goals
Before placing a single node, answer these questions:
- Who are the users? - Community members, emergency responders, ARES team, public? Each has different requirements.
- What is the geographic target area? - City, county, neighborhood, trail corridor? Define the boundary on a map.
- What quality of service is needed? - Best-effort casual use vs. mission-critical emergency communications have different reliability requirements.
- What is the budget? - A hobbyist community network might rely on volunteer-hosted nodes; a professional deployment might have a funded infrastructure budget.
Phase 2: Identify Candidate Sites
For each site, evaluate:
- Elevation - Higher is almost always better. Use topographic maps or USGS terrain data to identify hilltops, water towers, or tall buildings that have commanding views of the target area.
- Power availability - Mains power is most reliable; solar works at most outdoor sites; battery-only is acceptable for temporary or low-priority nodes.
- Accessibility - You will need to access this site for installation and maintenance. A perfect hilltop that requires technical climbing is impractical for most operators.
- Permission - Property owner permission is required. Start with sites where you have existing relationships: your own roof, a cooperating business, a friendly landowner.
Phase 3: Coverage Analysis
Before installing, verify coverage using tools:
- HeyWhatsThat.com - Enter your proposed repeater coordinates and height; generates a viewshed map showing where has line-of-sight to that point.
- Radio Mobile Online - More detailed propagation modeling including terrain, frequency, and antenna parameters.
- Field testing - Place a temporary node at the candidate site and drive/walk the intended coverage area while monitoring packet reception. This is ground truth.
Phase 4: Deployment Sequence
- Deploy the backbone first - Install your 2-3 highest-coverage repeaters before deploying fill nodes. The backbone provides the largest coverage gain per node installed.
- Test between backbone nodes - Verify each backbone node can communicate with at least one other backbone node before adding fill nodes.
- Add fill nodes for dead zones - Use coverage testing to identify gaps; deploy targeted fill repeaters.
- Recruit community members - Once basic coverage exists, recruit nearby property owners to host additional nodes. Their rooftops fill gaps and add redundancy.
Documentation and Handoff
Create documentation before deploying each node:
- Physical address or GPS coordinates of the site
- Property owner name and contact information
- Equipment installed (board type, firmware version, power system)
- Configuration (name, channel, advertisement settings)
- Access procedure (how to reach the installation for maintenance)
- Emergency contact (who to call if the node is causing problems)
Store this documentation somewhere accessible to all network operators - not just one person's laptop.
