Quectel BG77 – Time to change to NB-IoT and LTE-M

It’s time to switch to NB-IoT and LTE-M. With the Quectel BG77, anyone can now develop his or her own wristwatch with a cellular radio. With dimensions at only 14 mm x 15 mm, building a locating device in a matchbox is now possible. Since GNSS and cellular can be connected to one antenna interface, only one antenna is necessary. An external MCU is also unnecessary for the Quectel BG77. An ARM Cortex A7 with plenty of memory is available. The operating voltage ranges from 2.4 Volt to 4.8 Volt. In idle mode, the Quectel BG77 requires only approx. 2.4 uA. We started the pre-development of the small antennas 12 months ago. Inquiries about the Quectel BG77 Eval-Kit, about small antennas and about developments for small IoT devices are welcome to harald.naumann(at) lte-modem.com

  1. Hi,
    First of all thanks for a very nice resource and information.

    I would like to know if you have a product/design to sell which offers following solution:
    I want to use the sensor as a standalone IOT device to be used as a parking space sesnor i.e. to know if the vehicle is parked at specific parking lot or not. I would prefer a mobile network data connection.

    Please let me know if you already have something close to this off-the-shelf available and how much would this cost me. I am looking at both option i.e. one time design cost or buying a build product.


  2. Hi Haresh, sorry but there is nothing off the shelf.
