the beacon device

overview

  • beacon is a small egg-shaped device which can be used for many purposes.
    • it can trasmit pre-defined/programmed response to mother-devices
    • mother-device can record the responses to compose a meaningful message to users

usages

  • becaon periodically emits signals to the mother-device so that mother-device can check its existence
    • if it gets far enough from the mother-device, it alarms the mother-device
    • kindergarden-field-trip, family-visits-park
  • becaon can emit timestamp to mother-devices, mother-device can save timestamp -- e.g. for employee time clock system
  • can be used for authentication purposes -- i.e. beacon is an id
  • if beacon is nearby mother-device, i.e. n beacons are "physically-tied" to n mother-devices (say, cellphones), each mother-device can trasmit more powerful data (e.g. location data using cellphone's gps capability) to grandmother-device

requirements

identification

  • each beacon should have a unique id
  • even if the battery is dead, it still contains circuitry which draws power from the "reader" to send useful information, including its id

programmability

  • a beacon should be prorgammable -- i.e. user should be able to download a small piece of code (e.g. with functions with becaon library)

power

  • battery should be either replaceable or rechargeable
    • if not rechargeable, battery life should be at least 6 mos.
    • if chargeable, should be wireless-chargeable and battery life should be at least 1 week
  • for heavy-power-usages, it should be able to add "magnetic battery" attached to the beacon

storage

  • permanent storage (at least few MBs)

networking

  • bluetooth
  • wifi
  • rfid

sensors

  • it should contain multiple sensors, which users can use for many differet purposes

speakers

  • should at least beep

apps

  • mother-device, in most cases, are cellphones -- need apps to control beacons

light

  • should glow for indication purposes

implmentation

  • each beacon contains an id
  • mother-device can register id-usage into "cloud"
  • develope "meta-usage" map
