CHATFIELD
Farm and forestry communication becomes difficult when workers move between open land, buildings, machinery, access roads and tree cover while public network service changes from one zone to the next.
ChatField keeps the smartphone as the worker interface. Bluetooth connects the phone to a carried J25, and equipped J25 terminals form the local LoRa mesh communication layer for the defined team.
Procurement should evaluate the operation by work zone and shift route. That produces a usable trial plan and avoids treating one range figure as a guarantee for every part of the site.
WHO THIS PAGE IS FOR
Distributed crews working across land, woodland and equipment areas.
Crop and mixed farms
Coordinate workers moving between fields, storage areas, farm buildings and access routes.
Ranches and large estates
Support local team communication across wide land areas with changing terrain and mobile work roles.
Forestry operations
Evaluate communication along woodland roads, cutting areas, slopes and sections with dense vegetation.
Land-management contractors
Connect supervisors, equipment operators and field crews working across multiple task zones.
ZONE-BASED PLANNING
One property can contain several different radio environments.
The sample plan should divide the operation into zones before testing. Each zone has different obstacles, movement patterns and acceptance priorities.
Open fields
Long sightlines, moving people and vehicles, changing worker spacing.
Yards and buildings
Walls, metal structures, storage areas and fixed control points.
Woodland sections
Tree cover, route turns, slopes and reduced visual contact.
Roads and machinery
Moving equipment, operator position, noise and changing node placement.
SYSTEM WORKFLOW
The worker uses the phone; J25 carries the local radio link.
- 01Worker uses the phone appPTT, text, voice messages, offline map and worker-location functions remain on the smartphone interface.
- 02Bluetooth connects the paired J25The phone passes the local communication task to the carried J25 assigned to that worker.
- 03J25 exchanges data through LoRaThe terminal communicates with another participating J25 inside the configured local team network.
- 04Another equipped worker may support a pathWhen the network configuration and work-zone layout allow it, a participating J25 can support another local mesh path.
- 05The receiving worker sees it on the phoneThe receiving J25 passes the information to its paired smartphone for the operator.
J25 is a carried terminal paired with the smartphone. It should not be presented or evaluated as a conventional handheld walkie-talkie.
Review how the technology works →WORK-ZONE EVALUATION
Record the conditions that can change local communication.
Useful performance depends on terrain, vegetation, buildings, metal, antenna position, interference, equipment movement, node placement and the permitted market configuration.
| Work zone | Buyer inputs | Field trial method |
|---|---|---|
| Fields and pasture | Worker spacing, vehicle movement and device carry position | Follow the actual work route and record results at defined field edges and regrouping points. |
| Farmyard and buildings | Walls, metal structures, storage areas and control points | Test both outside and inside the locations used during the shift. |
| Woodland and tree cover | Vegetation density, slopes, route turns and seasonal change | Test inside the woodland rather than applying an open-field result. |
| Access roads | Moving vehicles, elevation changes and expected separation | Run the route using the same travel pattern and carry position planned for service. |
| Machinery areas | Metal, equipment position, noise and worker roles | Evaluate PTT, messages and location with machinery placed as it is during operation. |
PROCUREMENT REQUIREMENTS
Define the required workflows before requesting samples.
Group voice
Identify which supervisors, equipment operators and field workers need local push-to-talk communication.
Text and voice messages
Define short operational messages for tasks that do not require a live voice exchange.
Worker location
Confirm how equipped workers and defined positions should appear in the phone workflow.
Offline map context
Prepare the required field, road or woodland map data before leaving dependable internet access.
Local team SOS
Document the internal response procedure without treating it as a replacement for public emergency services.
Shift and team setup
Confirm the app build, worker groups, J25 allocation and operating instructions used for the trial.
UNITED STATES PROCUREMENT
Review model-specific FCC evidence.
For U.S. farm and forestry projects, the FCC-tested radio information should be matched to the final J25 configuration, project documents and quotation.

SAMPLE TRIAL
Test one real shift before commercial approval.
- Map the property.Fields, yards, buildings, access roads, woodland, machinery zones and known coverage gaps.
- Map the people.Team roles, shift pattern, moving routes, expected spacing and fixed control points.
- Define acceptance criteria.Required PTT, message, location, offline-map and local SOS workflows.
- Confirm the sample configuration.Market configuration, app build, device allocation, accessories and controlled documents.
- Run the shift route.Record pass or fail by work zone instead of relying on a stationary test alone.
- Finalize the quotation.Confirm quantity, branding, packaging, lead time and destination-specific documentation.
Important operating boundaries
What this solution supports
- Local communication for equipped farm and forestry workers
- Phone-paired PTT, messages, offline maps and worker-location workflows
- Zone-based testing for a defined property and shift
What buyers should not assume
- It is not satellite service or a public emergency network
- One range number cannot represent every field, building or woodland section
- FCC evidence does not replace final configuration and market review
Farm and forestry communication questions
Who is the farms and forestry solution designed for?
It is designed for professional farm, ranch, forestry, land-management and contract crews that need local team coordination across work zones with uneven cellular coverage.
How does J25 work with the phone?
The smartphone remains the interface for PTT, messages, maps and worker location. Bluetooth connects the phone to the J25 carried by each equipped worker, while J25 terminals provide the local LoRa communication layer.
How should buyers evaluate a farm or forestry site?
Divide the operation into fields, yards, buildings, access roads, woodland and equipment areas. Test the actual shift routes and record PTT, message and location results separately for each zone.
What FCC evidence is available for U.S. projects?
J25 FCC material identifies FCC ID 2BVP9-J25 and FCC Part 15C reports for LoRa operation at 903–927.5 MHz and Bluetooth Low Energy at 2402–2480 MHz.
What is needed for a farm or forestry sample quotation?
Provide the destination market, operation type, site zones, team size, shift routes, required workflows, sample quantity, estimated project volume and documentation requirements.
