CHATFIELD
ChatField develops phone-paired LoRa mesh communication for professional teams that need local voice, messages and location coordination when cellular and Wi-Fi coverage is unavailable or unreliable.
The same communication architecture can serve different industries, but the deployment plan should never be copied blindly from one field environment to another.
For procurement teams, the right starting point is the operating route, terrain, team movement and required functions—not a single advertised range number.
BUYER DECISION PATH
Define the communication problem before selecting the configuration.
- Coverage gapIdentify where cellular or Wi-Fi service becomes intermittent or unavailable.
- Team movementMap people, vehicles, vessels, checkpoints and the routes used during a shift.
- Terrain and obstaclesRecord buildings, trees, slopes, metal structures and other path conditions.
- Acceptance criteriaDecide which PTT, message, location and offline map workflows must pass a field trial.

Open the solution page that matches your team.
Each page explains the field problem, the phone-to-J25-to-LoRa mesh workflow, the no-cell-service communication use case and the practical questions a buyer should confirm before a sample evaluation.
Off-grid communication for moving teams beyond cell service
Plan local coordination for hiking guides, expedition staff, trail crews and field teams across changing terrain.
Explore outdoor teams →
LoRa mesh communication across land and woodland
Evaluate routes, vegetation, slopes, machinery and distributed work areas before deployment.
Explore farms & forestry →
Remote worksite communication without cell service
Map work zones, vehicles, structures and shift movement where public networks are limited or unavailable.
Explore remote worksites →
LoRa mesh communication for security patrols
Test entrances, perimeter sections, stairwells, night routes and control points using the real staffing pattern.
Explore security patrols →
LoRa mesh communication for marine operations
Separate vessel-to-vessel, vessel-to-shore, dock and obstructed harbor paths during evaluation.
Explore marine operations →
Backup communication for response support teams
Support local team communication when ordinary coverage is disrupted, without presenting J25 as a public emergency service.
Explore emergency response →THE COMMON SYSTEM
One phone-paired LoRa mesh workflow.
The smartphone remains the user interface. Each team member carries a paired J25 terminal; Bluetooth connects phone and J25, while the J25 terminals form the local LoRa communication layer.
- 01Phone appPTT, messages, map and location interface
- 02Bluetooth LELocal connection between the phone and paired J25
- 03Carried J25LoRa radio terminal carried by each equipped teammate
- 04Local meshDirect or participating-node path inside the configured team network
- 05TeammateReceiving J25 passes the information to the paired phone
WHAT CHANGES BY DEPLOYMENT
The field configuration must match the actual operation.
Destination market
The permitted radio configuration and required documentation are confirmed for the target country.
Terrain, spacing and range planning
Plan around the 5 km urban-obstructed field-test result, ideal open-terrain conditions up to 10 km, terrain, obstacles, antenna position, interference and how equipped teammates are distributed.
Required workflows
Buyers define which PTT, text, voice-message, team-location, offline-map and local SOS functions matter to the project.
Commercial scope
Sample quantity, project volume, branding, packaging, app requirements and controlled documents are aligned before quotation.
PROCUREMENT EVALUATION
A sample trial should reproduce the real route.
- Share the market and use case.Destination country, field environment, team size and intended functions.
- Define the trial route.Mark start points, checkpoints, obstacles, moving roles and expected team spacing.
- Confirm the sample configuration.Align radio configuration, app build, supplied accessories and supporting documents.
- Record pass or fail by workflow.Test PTT, messages and location behavior at the points that matter to the operation.
- Finalize the commercial quotation.Confirm quantity, branding, packaging, lead time and destination-specific documentation.
Important operating boundaries
What the system is designed for
- Local team communication beyond reliable cellular or Wi-Fi coverage
- Phone-paired PTT, messages and team-location workflows
- Field evaluation using the buyer’s real route and team layout
What must not be assumed
- It is not a satellite service or a substitute for public emergency networks
- No single range number represents every terrain or deployment
- Frequency, compliance evidence and documentation remain market-specific
Questions procurement teams ask
Which ChatField solution page should we read first?
Choose the page that most closely matches the actual operating environment. The six solution pages use the same core phone-paired LoRa mesh architecture but explain different terrain, route and acceptance-test priorities.
Does the J25 replace the smartphone?
No. The smartphone remains the interface for PTT, messages, maps and location functions. Each equipped teammate carries a J25 paired to the phone by Bluetooth.
Can ChatField promise one maximum distance for every project?
No. Ideal open-terrain communication can reach up to 10 km in plains, open line-of-sight routes or areas with limited hills, and ChatField uses around 5 km as the urban-obstructed field-test distance. Useful distance still depends on terrain, obstacles, antenna position, interference, node placement, relay layout and permitted configuration. A real-route field trial is the responsible basis for procurement evaluation.
What information is needed for a sample quotation?
Provide the destination country, application, team size, sample quantity, expected project volume, required functions and any branding, packaging or document requirements.
Where can buyers review compliance and technical evidence?
Start with the J25 specifications and compliance pages. FCC-tested radio data is kept separate from project-controlled items such as operating range, battery option and accessories.
