DOSnet is off-grid mesh communication hardware built on the Meshtastic platform. Each Connection Hub creates a private text and location-sharing network with other hubs nearby — no phone towers, no SIM cards, no internet connection required.

No. DOSnet doesn't use the mobile network at all. There's no SIM, no data plan, and no subscription fee — ever. You pay once for the hardware and it's yours.

Instead of every device talking to one central tower (like a mobile network), each DOSnet hub can talk directly to nearby hubs, and those hubs relay messages further along the chain. More hubs in the network means better coverage and more paths for a message to travel.

The free Meshtastic app, available for iOS and Android. Your DOSnet hub pairs to it over Bluetooth — the app is where you send messages, view the map, and see other hubs on your network.

No — DOSnet is a closed private network between hubs. Everyone you want to stay in touch with needs their own Connection Hub.

Messages travel over your own private mesh network between your hubs, not over the public internet or telco infrastructure.

Yes. DOSnet operates on the AU915 ISM band, which is license-free for low-power devices under ACMA regulations. No permit, license, or registration is required to use it.

Yes. DOSnet hardware is RCM certified (RCMP21580 001) and DOSnet holds ACMA responsible supplier registration (E22017). Batteries are UN38.3 certified for safe transport.

Yes — AU915 licensing is national, not state-based, so your hub works the same anywhere in Australia.

DOSnet hubs are configured for the AU915 frequency band used in Australia. Other countries use different frequency plans for LoRa devices, so a hub configured for Australia may not be legal or functional overseas.

No. DOSnet is for staying in touch with your own group — it is not a substitute for a registered emergency beacon or satellite SOS device. Keep carrying a PLB or sat phone for genuine emergencies.

Typically 2–5 km hub-to-hub in dense bush or hilly terrain, and 12+ km with clear line of sight (ridge to ridge, or open paddock). Property packages with Coverage Hubs extend this further — up to 45+ km depending on package tier and hub placement.

Terrain and elevation matter more than anything else. Hills, dense forest, and buildings between hubs reduce range; open country and elevated hub placement (a ridge, a roof, a tall post) significantly extend it.

Yes, two ways: add more Connection Hubs so messages relay further through the mesh, or add solar-powered Coverage Hubs at elevated points to act as dedicated repeaters.

LoRa radio (the technology DOSnet is built on) is generally robust in rain and typical Australian weather conditions. Heavy, dense vegetation has a bigger effect on range than weather does.

Meshtastic networks can support many devices — well beyond what a typical family, farm, or small team would need. Larger deployments (fleets, multi-site operations) should be scoped via a Tailored package.

An 8dBi high-gain antenna (omni or directional) extends range over the standard 5dBi antenna. A directional antenna is best for a fixed point-to-point link; an omni antenna suits general coverage.

3–4 days of typical use per charge on a Connection Hub, longer in standby with the screen off.

Connection Hubs charge via USB-C — from a power bank, a vehicle USB port, or a portable solar charger.

No. Coverage Hubs have an integrated solar panel and are designed to be mounted and left — no mains power or ongoing maintenance required.

Yes — spare batteries in standard and extended capacity are available as an add-on for longer trips off mains power.

Every hub arrives pre-flashed and pre-configured for AU915 — there's no firmware flashing or command-line setup. Charge it, pair it to the free app over Bluetooth, and you're connected. Typical setup is under 5 minutes per hub.

No. The hardware and app are designed for everyday use, not just technically-inclined users. A full property network typically takes under an hour to set up.

The highest practical point with clear sky exposure for the solar panel — a shed roof, a fence line post, or a water tank are common choices.

Yes — the Meshtastic app shows live GPS location sharing between hubs on your network, so you can see where everyone is on the map.

Yes — additional Connection Hubs and Coverage Hubs are available separately, so your network can grow as your needs change.

A single Connection Hub per person, or the 2-hub kit for a couple travelling together, covers most weekend bush trips. See the bush comms page for details.

The Farming package (12–25 km coverage) suits most standard properties; Community (31–45 km) suits larger or more spread-out land. See the property network page for a full breakdown.

The Tailored package includes a scoping call to plan hub placement around your specific terrain, buildings, and coverage needs.

Yes — individual Connection Hubs, Coverage Hubs, antennas, and batteries are all available separately if a fixed package doesn't match your needs.

A sat phone gives you voice calls anywhere with no ongoing infrastructure of your own, but costs money per call or month. DOSnet gives free group texting and location sharing with no ongoing cost, but only between your own hubs. Many people carry both.

A PLB or inReach is built for one job: emergency SOS to search and rescue. DOSnet is built for everyday group communication. They're complementary, not competing — keep your PLB for emergencies.

UHF radio is voice-only and range drops off quickly with obstacles. DOSnet's mesh network relays messages hub-to-hub, which can extend effective range further than a single UHF radio pair, plus it adds text messaging and GPS location sharing.

No. Starlink and home internet connect you to the wider internet; DOSnet is a private, local network for messaging and location between your own hubs. Different jobs entirely.

All orders ship from Brisbane, Queensland.

Yes, DOSnet ships across Australia.

Standard checkout payment methods available through the DOSnet store at checkout.

Yes, tracking details are provided once your order ships.

Contact dosnetwrk@gmail.com as soon as possible after ordering and we'll do what we can before it ships.

Support windows scale with package size — larger property and fleet packages include extended email and phone support. See the spec sheet for tier-by-tier details.

Contact dosnetwrk@gmail.com with your order number and a description of the issue, and we'll sort out a replacement or repair.

Each hub ships with a QR code card for instant app pairing. If you're still stuck, email dosnetwrk@gmail.com.

Contact dosnetwrk@gmail.com to discuss a return — we'll confirm eligibility and next steps based on your order.

Yes — standard Industry and Community packages cover most fleet-size orders, and the Tailored package handles custom quantities and deployment scoping. See the fleet procurement page.

DOSnet hardware is RCM certified and license-free under ACMA regulations. Site-specific compliance requirements (such as intrinsic safety zoning) should be confirmed against your own site's standards.

Yes — multi-site mesh planning is exactly what the Tailored scoping call is for.

Yes — email dosnetwrk@gmail.com with your requirements and we'll put together a formal quote.
