A Proposal for FENCE FREE.TECH

FENCE FREE.TECH: Rugged GPS Livestock Collar for Cattle and Goats

4–6 Weeks
USD 7,500
Provisional
01 — Background

Background

Disruptive Technology SAS is a Colombian agrotech company developing FENCE FREE.TECH, a livestock monitoring platform combining a rugged GPS collar, drone-based AI vision, and a cloud SaaS layer, for cattle and goat ranching. The GPS collar is the hardware component of the platform and is the subject of this proposal.

The collar is a from-scratch engineering project. No CAD or hardware design exists today. The functional specification calls for RTK positioning to approximately 30 cm accuracy with standard GPS as a fallback, dual connectivity through LoRaWAN as the primary channel and 4G LTE as backup and data upload, solar charging with 15 to 20 days of runtime without sunlight, an IP68 enclosure rated for continuous outdoor use on livestock, a skin contact body temperature sensor, and an onboard accelerometer that summarises activity locally before sending it over LoRaWAN. The device carries no shock or stimulation module. It is a monitoring device only.

A prototype supplier in Colombia has built a small batch of ten units for software field testing but cannot deliver the production hardware, and an earlier candidate factory could not confirm genuine OEM/ODM capability or deliver working RTK positioning. This is IP-sensitive hardware. The RTK and LoRaWAN engineering is the core of the product, and any factory asked to quote it needs to see that engineering in detail. This project needs an engineering partner who can take the specification from idea stage through to a manufacturing-ready design under one accountable roof, rather than sharing that engineering with several unverified factories before a manufacturing agreement exists.

Two markets are active now. A first order of 1,000 collars for Galicia, Spain, tied to a regional government relationship, with an annual forecast of 7,000 units and a second market in Colombia to follow.

This proposal covers Phase 1 of the development program, Engineering Validation, following the discovery call held with Jesus Romano on 17 July 2026.

03 — Phase 1

Phase 1, Engineering Validation

Phase 1, Engineering Validation is the first paid engineering engagement in the FENCE FREE.TECH collar development program. The work is engineering led: a feasibility assessment translating the functional specification into an initial architecture, a dedicated workstream on the positioning, connectivity, and power tradeoff at the centre of this product, a preliminary DFM, DFA, and DFX assessment, a supplier engineering shortlist with indicative pricing, and a Development Roadmap that consolidates the output into a costed, phase-by-phase pathway to qualified mass production.

Duration: 4 to 6 weeks from confirmation.

This proposal contracts Phase 1 only. By its conclusion, FENCE FREE.TECH will have a validated architecture direction, a realistic position on RTK accuracy and battery autonomy, an indicative unit-cost model supported by supplier engagement, a confirmed development and certification pathway, and a costed milestone plan through to production-ready units. Sections 4 to 6 set out the indicative framework beyond Phase 1 for planning; each subsequent stage is separately scoped and authorised.

Phase 1 consists of the following six deliverables.

01
Engineering Kickoff Workshop.
A working technical session with the Shield Works R&D team, not an introductory call. We walk through the full functional specification, the two-market certification targets, and the engineering priorities, and agree the workstreams before work begins.
02
Design Feasibility Assessment.
This deliverable replaces the standard CAD and BOM audit, because no CAD exists yet. Output: a written feasibility assessment of the functional specification against real hardware constraints, translating the spec into an initial architecture direction for CAD, BOM, and electrical schematics.
03
Positioning, Connectivity, and Power Budget Feasibility Model.
The central technical workstream. RTK positioning accuracy, correction source strategy (network RTK over cellular versus a fixed base station), and the standard GPS fallback, modelled against the power draw of LoRaWAN and 4G duty cycling and the 15 to 20 day solar autonomy target on a moving animal. The model assesses cattle and goat configurations separately, because battery capacity, enclosure size, weight, and achievable RTK duty cycle may require different architectures for the two animal types. Includes the accuracy realistically achievable in each target environment and market. Output: a documented engineering position on how RTK accuracy, connectivity, and power budget are balanced, with a recommended architecture direction.
04
Preliminary DFM, DFA, and DFX Engineering Assessment.
Covers the IP68 enclosure and strap design for outdoor livestock use, the skin contact temperature sensor and accelerometer integration, component sourcing direction for the RTK module including compatibility with named candidates such as the u-blox ZED-F9P and Quectel LG290P, the LoRaWAN and 4G module selection, and a certification pathway for the EU (Galicia) and Colombia markets. Includes a structured risk register with mitigations.
05
Supplier Engineering Shortlist and Indicative Quotation.
Qualified supplier shortlist across the RTK and connectivity modules, the solar and battery system, and IP68 enclosure manufacture, with first-round engineering engagement to confirm capability. Indicative unit pricing at multiple volume tiers aligned to the 1,000 unit first run and the 7,000 unit annual forecast.
06
Development Roadmap (Full RTMP).
The 30 to 40 page consolidating document carrying the Phase 1 output forward into Phase 2 and through to qualified mass production. Contains phase timelines, phase management costs, component-level BOM, mechanical and electronic plans, the certification pathway for both markets, prototyping plan, pilot run plan, mass production pathway, and risk register.

Fee: USD 7,500, payable in full on project confirmation.

04 — Development Budget

Development Phase Budget

The figures in this section are indicative planning ranges. They are built from an engineering breakdown of the work and current supplier and test-house pricing, not from a finished design. They are not quotes and not commitments. Each figure is confirmed and locked against real supplier quotes through Phase 1 and the Development Roadmap that follows it.

Pasquale asked for an indicative view of development cost, the timeline, the milestone payment structure, and certification cost ahead of Phase 1. Those are set out below. This budget covers the development phase, taking the product from idea stage to a production-ready design with a full production tech pack. Certification is set out separately in Section 6, and tooling and mass production in Section 5.

4.1 Development phase budget

Indicative planning ranges for the development phase. Certification (Section 6) and the tooling and pilot (Section 5) are shown separately and are additional. Firm figures are set through Phase 1 and the Development Roadmap that follows it.

StageScopeTimelineIndicative Fee
Phase 1, Engineering ValidationFeasibility, positioning and power model, DFM/DFX, supplier shortlist, Development Roadmap4 to 6 weeksUSD 7,500
Industrial design, CAD, mechanicalEnclosure, strap, sensor and antenna placement to manufacturing standard5 to 8 weeksUSD 12,000 to 15,000
Electronics and power systemsTri-radio board (RTK, LoRaWAN, 4G), power management, sensor integration8 to 12 weeksUSD 18,000 to 22,000

PrototypingThree prototype rounds, build and test6 to 8 weeksUSD 16,000 to 22,000
DFMDesign for manufacture, iterated against each prototype round, in parallel with prototypingparallelUSD 9,000 to 13,000
Design freeze and production tech pack2D drawings, final BOM, quality standards, production work instructions3 to 4 weeksUSD 10,000 to 13,000
Program managementMulti-partner, two-market program coordination across the development periodfull periodUSD 4,000/month, USD 32,000 to 36,000
Development phase totalStages partly in parallel, certification separate (Section 6)approx. 7 to 9 monthsUSD 130,500 to 164,500

Risk note. The electronics and firmware stage is the most likely to run to the top of its range. A tri-radio board sharing antennas across RTK, LoRaWAN, and 4G raises RF coexistence and power management challenges that are resolved, and priced firmly, during Phase 1. The positioning, connectivity, and power model in Phase 1 is designed specifically to de-risk this before development begins.

4.2 A note on target unit cost

Pasquale has indicated a target ex-factory price of USD 40 per unit. We want to be direct on this, because it shapes the commercial plan. A collar combining RTK positioning, dual LoRaWAN and 4G connectivity, solar and rechargeable power, an IP68 enclosure, and two onboard sensors is genuinely complex hardware. The RTK module alone is the single largest line in the bill of materials, and the choice of module is the main cost lever: a mass-market high-precision part supports the lower end of the range, while a higher-precision professional module carries a materially higher cost. On an indicative basis at a 1,000 unit first run, we would expect an ex-factory unit cost in the region of USD 115 to 190, likely narrowing toward the lower end at the 7,000 unit annual run rate. This is indicative only and is not a quote.

A target of USD 40 is not reachable for an RTK collar of this specification at these volumes. Standard GPS livestock collars on the market sit far lower in cost, but they do not deliver the centimetre level positioning that defines this product. Phase 1 will identify the lowest credible cost architecture and show the cost and performance impact of the principal design choices, particularly the RTK module, correction strategy, cellular duty cycle, battery capacity, and cattle-versus-goat form factor, before any production commitment is made.

Other than the fixed Phase 1 fee, no downstream development cost or production unit price is committed in this proposal. Component selection, RTK correction strategy, battery sizing, and certification scope across two markets all materially affect both numbers. They are established and locked only through the Phase 1 engineering work.

4.3 Timeline to production

The milestones below give an indicative view of the path from Phase 1 through to production-ready units, timed from Phase 1 start. Certification cannot begin until a validated prototype exists, so it sits toward the back of the program and runs in parallel with tooling. The detailed, firm timeline is a Phase 1 deliverable within the Development Roadmap.

MilestoneIndicative Timing from Phase 1 Start
Phase 1 Engineering Validation completeWeek 4 to 6
Design, electronics, and firmware completeMonth 3 to 5
First functional prototypesMonth 4 to 5
Prototyping and DFM complete (run in parallel)Month 5 to 6
Design freeze and production tech packMonth 6 to 7
Certification testing and submission (two markets)Month 6 to 9, once prototypes validated
Tooling completeMonth 7 to 9
Pilot run and production-ready unitsMonth 8 to 10

Indicative only. Stages overlap, so the milestones are not additive. Prototyping and DFM run in parallel, followed by design freeze and the production tech pack. Mass production of the first 1,000 unit run sits beyond production-ready units.

The stated 3 to 4 month objective for production is not achievable for a from-scratch, certified product of this complexity. The earliest credible route to production-ready units is the 8 to 10 month pathway above. Phase 1 establishes the firm critical path and identifies any opportunities to compress individual stages without compromising technical validation or certification readiness.

4.4 Milestone payment structure

Phase 1 is invoiced in full on confirmation. Each subsequent stage is separately authorised against the firm scope and fee established through the Development Roadmap. Engineering milestones are normally billed through an agreed commencement and completion payment structure. Third-party development, prototype, tooling, and certification costs are payable before commitment to the relevant supplier, partner, or test house. The program management retainer is billed monthly across the development period. This keeps payment aligned to delivered work while ensuring external costs are funded before they are committed.

  • Milestone 1: Phase 1 Engineering Validation, in full on confirmation.
  • Milestone 2: Industrial design, CAD, mechanical, commencement and completion.
  • Milestone 3: Electronics and power systems, commencement and completion.
  • Milestone 4: Firmware, commencement and integration milestone (partner cost funded before commitment).
  • Milestone 5: Prototyping and DFM, prototype build costs funded before commitment, engineering on delivery of validated prototypes.
  • Milestone 6: Design freeze and production tech pack, on release.
  • Retainer: Program management, USD 4,000 monthly across the development period.

Certification (Section 6) test-house fees are payable before submission for each market. Tooling and pilot (Section 5) are funded before commitment to the toolmaker and the pilot build.

4.5 Engineering notes and points to confirm

Two points from our review that we want to put on the record now, so they are settled at kickoff rather than later.

  • Positioning module. The functional specification names the u-blox ZED-F9P, a proven professional-grade RTK receiver and a sound choice. During Phase 1 we will confirm it against the Quectel LG290P, a newer high-precision module that may meet the target accuracy at lower unit cost and lower power draw, which bears directly on the solar and battery autonomy target. Both are strong candidates. The final selection is made in Phase 1 against the accuracy, power, and cost targets together.
  • Power and charging. The specification is built around solar charging with a rechargeable battery. An earlier note also referenced Qi wireless charging. Wireless charging can be included, but it affects the IP68 enclosure and the power system, so we would like to confirm at kickoff whether the intended method is solar plus battery, Qi wireless charging as well, or both.
05 — Tooling & Production

Tooling and Mass Production

The items below are the production tooling and pilot activities. They sit outside the development phase budget in Section 4 and are undertaken at the production stage, once the design is validated. First production stock is a further separate cost, sized to your order volumes.

Indicative planning ranges. Tooling is a one-time cost, carried forward into production. The pilot is an off-tool validation batch and excludes pilot shipping. First production stock is quoted separately against your order volumes.

StageScopeTimelineIndicative Fee
ToolingEnclosure moulds and strap hardware, one-time, carried forward to production6 to 10 weeksUSD 16,000 to 30,000
Pilot runOff-tool validation batch of approximately 50 units, excludes pilot shipping3 to 4 weeksUSD 12,000 to 23,000
Tooling and pilotProduction stageUSD 28,000 to 53,000
06 — Certification

Certification

Certification is shown separately because it is largely test-house work coordinated by Shield Works rather than development engineering, and because it is gated: it can only begin once a validated prototype exists, so it sits toward the back of the program. The collar is a three-radio, animal-worn, IP68 device sold into two markets, which sets the scope below. Using pre-certified radio modules should reduce the radio test scope, although conformity testing remains necessary at the completed product level.

EU market (RED):

  • EMC, EN 301 489 series (multi-radio).
  • Electrical safety, EN 62368-1.
  • RF exposure assessment for an animal-worn radio device, IEC 62311.
  • Cybersecurity, EN 18031, mandatory since August 2025.
  • Ingress protection, IP68, IEC 60529.
  • Environmental compliance, including RoHS requirements for the EU market.

Colombia market:

  • CRC and ANE homologation, with FCC or CE reports accepted, TAC, IMEI listing, and a Spanish user guide.
Indicative Certification Fee
USD 25,000 to 45,000
EU and Colombia
Timeline 8 to 12 weeks, beginning once a validated prototype exists

Indicative planning range, firmed during the program against test-house quotes. The top of the range reflects the full multi-radio and cellular scope; deferring cellular carrier certification brings it down. The device's processing and transmission of location data may bring it within the applicable RED cybersecurity requirements; the conformity-assessment route, including whether Notified Body involvement is required, is confirmed with the selected test house during the program. US or FCC certification is not in scope and would be a separate cost.

07 — Factory Verification

Optional: Independent Factory Verification (iStartek and Skywonder)

Separate from the development program, Pasquale has asked us to independently verify iStartek and Skywonder as a benchmark against the Shield Works development path. We can run this as a standalone engagement, alongside Phase 1 or on its own timeline.

  • Confirming genuine manufacturer status for both factories, rather than a trading company presenting as one.
  • Assessing OEM/ODM engineering capability against the collar specification.
  • Reviewing certifications and test reports (CE, FCC, RoHS, IP68) held by each factory.
  • Checking production capacity at both sites, in Shenzhen (Longgang/Bantian) and Huizhou.

Fee: USD 650 per factory, USD 1,300 for both.

The current scope covers iStartek and Skywonder. MOKO SMART, from your original enquiry, can be added at the same USD 650 per-factory rate if you would like it included.

08 — Exclusions

Exclusions

This proposal contracts Phase 1, Engineering Validation only. Sections 4, 5, and 6 provide the indicative development, tooling, pilot, and certification framework requested for planning and funding purposes; each subsequent stage is separately scoped, confirmed, and authorised before work begins. The following sit outside the proposal entirely:

  • First production stock. The 1,000 unit first run and subsequent production are a separate cost, sized to your order volumes.
  • Shipping, freight, insurance, duties, and taxes on samples, prototypes, pilot units, and production.
  • Ongoing operating costs. Correction-service subscriptions (NTRIP or PPP-RTK), SIM and cellular data, and any cloud hosting.
  • Your platform. The cloud SaaS, AI backend, and drone vision system are your own scope and are not part of the collar hardware program.
  • On-animal field trials and their logistics.
  • Redesign arising from a change to the functional specification after kickoff, which would be scoped and quoted separately.
  • The independent factory verification, available separately in Section 7.

10 — Safeguards

Safeguards and Clarifications

Positioning accuracy is environment dependent.
The approximately 30 cm RTK target is achievable in open sky with a live correction stream, as in open Galician pasture. Performance under tree cover, and in areas with limited correction infrastructure, is lower. The accuracy achievable in each target environment, and the correction strategy for each market, is specified during Phase 1.
All development cost and unit cost figures in Section 4 are indicative only.
They are preliminary ranges, not quotes and not commitments. Firm figures are established and locked against real supplier quotes through Phase 1 and the Development Roadmap.
Indicative unit pricing in the Phase 1 quotation is accurate to the level of design and supplier readiness at that stage.
Final unit costs are locked against firm supplier quotes as Phase 2 progresses.
Certification requirements are confirmed during Phase 1 and are not transferable from any other product.
The certification figure in Section 6 is an indicative planning range; test-house fees are firmed during the program.
Component selection, including the RTK module, is confirmed through the Phase 1 engineering work.
Reference to named candidates such as the u-blox ZED-F9P and Quectel LG290P reflects current direction, not a locked commitment.
Progression to Phase 2.
Gated on agreement of the architecture direction, the Phase 1 indicative quotation, and the overall development budget set out in the Development Roadmap.
