[hemmerling] Wireless Networks

Frequencies

  • 2.4 Ghz → Mostly normed wireless communications :-). Good range in US style ( “wooden” ) houses :-), weak range in European ( “stone & armored concrete” ) houses.
  • 868 Mhz → Wireless M-Bus :-), KNX PLC = KNX RF :-), but mostly proprietary wireless communications :-(, often due to “all inclusive service” service models of service providers. Acceptable range in European ( “stone & armored concrete” ) houses, higher range than with 2.4 Ghz.
  • 433 Mhz is “the future” from point of view of some technology experts.

  • I was told by experts: Since 2014, placing a Bluetooth enabled product on the market requires to pay a license fee for each single item :-(. Before that, buying a “complete Bluetooth module” of a sub-manufacturer and integrating it into the product, was not subject of a license fee :-). With a complete Bluetooth solution, you must not pay.
  • Bluetooth LE enabled devices and operating systems:
  • Quora "Is there a difference between Bluetooth 4.0 and Bluetooth Low Energy? If so, what?" - “In the new specification, BT 4.1 we have the hub. You will find such a hub in a smart watch for sports. The watch will work in the central mode in direction to the heart rate belt and other senors on the bike and in peripheral mode in direction to the smartphone”.
  • PC Magazin "Bluetooth 4.2 erklärt: Das kann die nächste Version" - “Zu guter Letzt wurde mit der Version 4.2 eine sichere und variable Verbindung zum Internet geschaffen – nach Paketstandard IPv6, mit dem sich die Anzahl der möglichen Geräte potenziert. So kann nun das Internet der Dinge, also Haussteuerung (z.B. Beleuchtung, Heizung, Sicherheit), Smart Meters und Kommunikation mit Haushaltsgeräten auf Basis von Bluetooth entwickelt werden. Ist ein Übergabepunkt zum WWW vorhanden, kann dann alles weltweit gesteuert werden”.
    • “Bluetooth 4.2 introduces several new features that improve speed and privacy over Bluetooth 4.1 but the main advantage is allowing chips to use Bluetooth over Internet Protocol version 6 (IPv6) for direct Internet access. With this, the possibilities expand beyond thoseof current designs and markets to include any type of Bluetooth device requiring speed and security in the IoT”.
      • IoT Capabilities:
        • Low-power IP (IPv6/6LoWPAN).
        • Bluetooth Smart Internet Gateways (GATT).
      • “With BLE 4.2 Bluetooth Smart sensors can transmit data over the internet”.
    • “Symmetry Electronics is able to support your BLE 4.2 designs with the recently released Silicon Labs Blue Gecko line of BLE modules and development tools. The certified Blue Gecko module allows you to quickly add Bluetooth connectivity to your applications with software stack and an intuitive scripting language for development”.

EnOcean

The EnOcean Allicance

Partners

Associates

  • At the “Funk-Roadshow 2011” on 2011-11-15 in Hamburg, all participants were invited to become sponsored “EnOcean Associate” for 2 years. To apply for this sponsored membership at EnOcean Alliance Application Form, select “Application as = 'Associate'” and at “Sponsored by:”, please enter “Roadshow 2011”.
    • Regularly, the membership fee as “Associate” is $500 ( USD) for 2 years.
    • So if your business partnership should not result in a monetary benefit :-), be shure to cancel the free membership in time.
    • Remember “Fees apply ... from date of registration”. If you do not cancel the membership, you wll pay $500 for the 3rd. and 4th. year, and furtheron.
    • The contract documents in German language do not contain:
      • A return address of the organization. It is just printed on the website ( postal address, FAX telephone number, E-Mail ).
      • A “period of cancellation” ( “Kündigungsfrist” ).
      • The required form of a membership cancellation ( e.g. just cancellation by a paper letter and FAX letter, or even by E-Mail ? ) :-(.
    • However, the German contract documents contain severe typing mistakes ( “Einschräkungen” ), and part of the German contract text is written in captalized letters, which makes it hard to read even for German natives :-(.

NFC

NFC Implementation by Smartphones

  • I was told by experts:
    • Apple iPhones 6,7 just implement an NFC “Card”.
    • Android Smartphones with NFC support are used to implement the full NFC standard ( “Card”, “Reader”, “Peer2Peer” ).

ZigBee

  • The ZigBee V1.0 specifications do not define an IP-based protocol, in favour of little bandwidth.
  • The ZigBee Smart Energy V2.0 specifications define an IP-based protocol.

Important w-power wide-area-network protocols/networks according to VDC Research, 2016

  • Haystack.
  • LoRaWAN (LoRa Alliance).
  • NB-IoT (3GPP).
  • Senet.
  • SigFox.
  • RPMA (Ingenu).

  • Experts told me:
    • With LoRa, you may spread the spectrum, so that you have both the option for high data volume ( with lower range ) and low data volume ( with maximum range), e.g. 20 messages/d.
    • With Sigfox, you are limited to e.g. 20 messages/d.
    • In comparison to LTE-Narrowband, LoRa and SigFox have very limited bandwidth.
