French Company Building a Mobile Internet Just For Things 35

holy_calamity writes "France now has a dedicated cellular data network just for Internet-of-Things devices, and the company that built it is rolling out the technology elsewhere, says MIT Technology Review. SigFox's network is slower than a conventional cellular data network, but built using technology able to make much longer range links and operate on unlicensed spectrum. Those features are intended to allow the service to be cheap enough for low cost sensors on energy infrastructure and many other places to make sense, something not possible on a network shared with smartphones and other consumer devices."

    The cute trick is that this technology is extremely slow, as in, low bandwidth, per TFA. We are talking 100 bps. (Not 100 kilobytes per second, but 100 bits per second).

    So, no, nobody is dumping their cellular data plan for this. But for a weather station, or "where is the bus right now?", or burglar alarms, it could be interesting.

    The main "problem" I see is that more expensive, more capable networks (cellular and wifi) are already so pervasive.

    Ah, but a firmware update is very easy to install. Just power-cycle or reset the device and push a firmware update OVER-THE-AIR. What could possibly go wrong ? [trollface.jpg]

    Quot from the PDF on their site (emphasys mine):
    4 Bootloader

    The TD1202 module contains an integrated bootloader which allows reflashing the module firmware either over the RX/TX UART connection, or over the air using the built-in RF transceiver.

    The bootloader is automatically activated upon module reset. Once activated, the bootloader will monitor the UART/RF activity for a 200 ms period, and detect an incoming update condition.

    If the update condition is met, the TD1202 will automatically proceed to flash the new firmware with safe retry mechanisms, or falls back to normal operation.
