MOLECULEX CONNECTED-DEVICE PLANNING CHECKLIST Free working checklist | Version 27 October 2026 Project: Owner: Date: Model currency: Planning horizon: For each input record: value, units, source/date and confidence. Use MEASURED, ESTIMATED or UNKNOWN. Do not silently treat unknowns as zero. 1. DEVICE AND POWER [ ] Battery capacity and usable-capacity assumption [ ] Active, transmission and sleep current [ ] Time spent in each operating state [ ] Reporting interval, retries and connection setup [ ] Temperature, ageing and self-discharge assumptions [ ] Required battery/service interval [ ] Evidence from representative current measurements 2. CONNECTIVITY AND DATA [ ] Payload size, protocol overhead and messages per day [ ] Downlinks, retries, reconnects and firmware updates [ ] Devices per SIM or connection [ ] Plan allowance, monthly price and overage charges [ ] Coverage, gateway/infrastructure and installation needs [ ] Supplier quote, region and applicable currency 3. FLEET ECONOMICS [ ] Starting device count and expected growth [ ] Hardware, installation and provisioning costs [ ] Recurring connectivity, platform and support costs [ ] Expected failures, replacements and field visits [ ] Spares, taxes, inflation and currency assumptions [ ] Expected benefit and the evidence behind it [ ] Discount rate and planning horizon 4. COMPARE OPTIONS [ ] Define architecture A and architecture B [ ] Use the same currency and planning horizon [ ] Separate shared assumptions from option-specific inputs [ ] Test low, expected and high cost assumptions [ ] Record which assumptions could change the preferred option 5. VALIDATE BEFORE COMMITTING [ ] Measure representative power consumption [ ] Confirm real connectivity coverage and behaviour [ ] Validate vendor pricing and minimum charges [ ] Review RF, regulatory, safety and security requirements [ ] Identify model exclusions and missing evidence [ ] Assign an owner and date to each validation step Free architecture check: https://moleculex-05p2hp.v2.appdeploy.ai/tools/connected-device-decision-engine/ Worked sample (synthetic assumptions): https://tbrucestudio.com/moleculex-sample-economics-report.html Planning support only.
