  • Open source instead of proprietary

Advantage of Google´s Radio protocol

  • Better coverage in buildings
  • End-to-end security if they use IPsec
  • Proven standard IPv6 plus 6LoWPAN
  • No NDAs
  • No approval process to build accessories

Benefits of Google´s Radio protocol

  • No licence fee
  • Lower BOM
  • Maybe like lower power consumption
  • Frequency hopping is complain to the new EN 300 328 V1.8.1

Google  was so clever to think about making their Open Source radio  protocol  complain to the new version of EN 300 328 V1.8.1. If EN 300  328 V1.8.1  will be released like it is, all Direct Sequence Spread  Spectrum system  on  802.15.4 has to be de-installed.
