Hosting a Thumb Mesh Repeater Frequently Asked Questions

1. What is Thumb Mesh, exactly?
   Thumb Mesh is a communications cooperative of sorts, but for everyone and at no cost to the user. A user can buy a small radio (not from us!) at $15 - $120 and have continual access to this network with no monthly fees, or fees of any kind, ever.
   
   
2. What can a user do on the Thumb Mesh netork?
   Thumb Mesh is built around the meshcore networking stack, and as such can send short text messages tens to hundreds of miles in seconds. This can be used for emergency communications when cell towers are down or overloaded, to coordinate a search party, to update a partner's shopping list, or just have a chat.
   
   
3. What exactly is the repeater being used for?
   Repeaters relay messages across the thumb, allowing us to send messages long distances with cheap equipment that doesn't need expensive licensing.
   
   
4. What kind of equipment will be installed?
   Typically a small, weatherproof box containing a microcontroller and battery A lightweight antenna and a solar panel Usually under 2 pounds and compact (roughly the size of an internet router, but the antenna is longer)
   
   
5. Will a repeater increase my power bill?
   Repeaters are solar-powered and self-sufficient and as such have no cost to the site owner.
   
   
6. Will a repeater increase my internet bill or usage?
   Repeaters do not require internet access an as such will not change the cost or speed of your internet.

7. What kind of antenna or cabling will be involved?
   Usually a small antenna is attached directly to the repeater. In some cases, a small external antenna may be mounted on a mast or pole to improve coverage. No cabling enters the building.
   
   Typical installations use industrial magnets, U-bolts around a mast or pole, or heavy-duty UV-resistant zip ties. No drilling or permanent modifications are required unless agreed upon in advance.
   
   
8. What is the expected maintenance requirement?
   Very little. Repeaters are designed to operate autonomously for long periods. Occasional visits—typically once or twice a year—may be needed for firmware updates, battery replacement, or general hardware inspection.
   
   Access arrangements can be agreed upon in advance.
   
   
9. Can I have details of what the repeater does?
   The repeater extends the Thumb Mesh network by relaying messages between other nearby repeaters and user radios.
   
   It enables a region-wide text messaging system that allows users to exchange public or private messages across long distances without relying on cellular service or the internet.
   
   Common uses include emergency preparedness, outdoor recreation, search and rescue support, community events, and keeping rural communities connected.
   
   
10. What range and signal coverage will this repeater support?
    Coverage depends primarily on antenna height and surrounding terrain. Typical coverage ranges from several miles to well over ten miles, with much greater distances possible from elevated locations.
    
    The repeater helps extend communication by automatically relaying messages through other repeaters in the network.
    
    It operates in the license-free 902–928 MHz Industrial, Scientific, and Medical (ISM) radio band.
    
    
11. Will the equipment cause any interference with my existing systems?
    Interference is extremely unlikely. Thumb Mesh operates on different frequencies than Wi-Fi, cellular networks, television, and most other consumer electronics while transmitting at relatively low power.
    
    The equipment is designed to comply with applicable FCC regulations. Documentation can be provided if requested.
    
    
12. Are there any permits, zoning, or regulatory issues to be aware of?
    Small, non-commercial radio installations generally do not require permits.
    
    Because installations normally require no drilling or permanent alterations, they can usually be removed without leaving damage.
    
    If you rent your property, we can work directly with your property owwner.
    
    
13. Will this use the building's power or increase the likelihood my property is struck by lightning?
    No. Repeaters are solar powered and operate independently of your building's electrical system.
    
    Using a completely self-contained solar power system also avoids connecting the equipment to your household wiring.
    
    There is no evidence that the installation increases the likelihood of a lightning strike.
    
    
14. How long is the repeater expected to stay there? Can it be removed at any time?
    That is entirely up to you. We can agree on whatever timeframe works best, with no long-term obligation.
    
    You may request removal at any time, allowing reasonable notice to arrange access.
    
    The goal is for removal to leave no permanent marks or damage.
    
    
15. Who else hosts Thumb Mesh repeaters?
    Thumb Mesh is a new community network, so our list of host sites is still growing.
    
    As additional repeaters are installed across Michigan's Thumb, we plan to publish examples of participating businesses, organizations, and property owners (with their permission).
