Capability requirements and tolerances

Consumer-specific numerical targets, quantities and acceptance limits remain open or incompletely reviewed. No smartphone-grade suitability is claimed. Distinct capability tiers require their own making route and qualification.

Making outline

  1. Build cellular and local-radio hardware plus navigation and NFC candidate capabilities; chosen bands, legal identity, antenna placement and interoperability remain unknown
  2. Develop a bounded process specification and establish earlier availability of every listed physical prerequisite.
  3. Make trial pieces, measure interfaces and performance with independently established references, and reject incompatible outputs.
