[TriEmbed] Wireless radio communications for microcontrollers

[Scott Hall]

Recently in TriLUG, TriEmbed and TriBRAE meetings we have talked about various
options to send data over a wireless link.  They include:

  * Near field communications (NFC) - limited range to a few inches
  * Bluetooth LE - designed for PAN (Personal Area Networks) limited to a few feet
  * Zigbee - low power SAN (Small Area Networks) limited to tens of feet, maybe
    a hundred feet
  * 802.11-based Wi-Fi - limited to same as Zigbee but tied into the Internet
    infrastructure
  * Narrowband IoT (NB-IoT) - power hungry radios using licensed cellular
    infrastructure to carry over many miles
  * LoRa and Sigfox - low-power, long-range radios in unlicensed ISM bands
    designed to carry over many miles
