MINIATURE WIRELESS
TELEMETRY DEVICE
Presale feasibility study for a compact wireless telemetry module designed for military and law enforcement training range applications.
THE CHALLENGE
A defense industry client required a miniature wireless telemetry device for installation on training range equipment. The device needed to capture real-time positional, motion, and environmental data and transmit it wirelessly to a base station over operationally relevant distances.
The constraints were demanding: the entire module had to fit within a 50 x 50 x 25 mm enclosure weighing under 100 grams, survive harsh field conditions at IP68 rating, and maintain reliable radio links at 3–6 km range — all while running on battery for extended training sessions.
OUR APPROACH
Full system architecture covering MCU selection, sensor integration (GNSS, 9-axis IMU, barometer, temperature/humidity), sub-GHz radio topology, and power management. Block diagrams, interface definitions, and firmware architecture mapped end-to-end.
Comprehensive 87-part Bill of Materials with dual-sourcing strategy. Every component evaluated against availability, lead time, military temperature range, and cost. Full BOM costed at unit and batch quantities with supplier alternatives identified.
Deep-dive feasibility studies on the three highest-risk areas: RTK-grade positioning accuracy within size constraints, battery capacity vs. weight budget tradeoffs, and RF link budget analysis for sub-GHz at 3–6 km with terrain and vegetation models.
Complete commercial package including development timeline, milestone-based pricing, risk matrix, and production cost projections at 100/500/1000 unit volumes. Interactive client portal with all deliverables for stakeholder review and async collaboration.
KEY DELIVERABLES
- System Architecture Document — block diagrams, interface specs, firmware stack
- 87-Part Bill of Materials — costed, dual-sourced, availability-verified
- Mechanical Specification — enclosure design, IP68 sealing strategy, weight analysis
- Battery Feasibility Study — cell comparison, runtime projections, charging architecture
- RF Link Budget Analysis — sub-GHz propagation modeling, antenna selection, range validation
- RTK Positioning Assessment — GNSS module evaluation, accuracy vs. size tradeoffs
- Commercial Proposal — phased timeline, pricing, risk matrix, volume projections
- Interactive Client Portal — all documents, specs, and BOM in a web-accessible workspace
RESULTS
Complete presale package delivered in 48 hours. The client received a fully researched technical architecture, validated component selection with sourcing alternatives, quantified risk assessments on the three critical feasibility questions, and a milestone-based commercial proposal — all accessible through a dedicated interactive portal.
This engagement demonstrates our ability to rapidly produce investment-grade presale engineering: deep enough to de-risk a hardware development commitment, fast enough to maintain deal momentum, and structured for non-technical stakeholder review.
