Rescue from the air for lone workers

Rescue from the air – IoT Project 1 In this issue of the IoT M2M Times, we explain a complete IoT project for the first time. We explain the project including the selection of radio modules and antennas. Telling this story is possible because it is an EU funded...

Energy-saving with NB-IoT and LTE-M part 1

Energy-saving with NB-IoT and LTE-M part 1 – NB-IoT / LTEM versus GSM  In this series of three blog articles, adapted from the IoT M2M Times, we take a closer look at the energy consumption of NB-IoT and LTE-M. On their own, these physical layer standards do not...
GSM / NB-IoT PIFA antennas that fly

GSM / NB-IoT PIFA antennas that fly

GSM / NB-IoT PIFA antennas that fly As any antenna designer or an informed person who has read the IoT/M2M Cookbook knows, metal and antennas do not play well together. Many times, we are contacted by frustrated designers who find that the antennas they are using...
GNSS Antennas and Recycling

GNSS Antennas and Recycling

GNSS Antennas and Recycling DIY GNSS (GPS/Galileo/Glonass/Beidou) Antenna Everybody talks about protecting the environment and recycling. The nail antenna from the land of poets and thinkers (Germany) follows this trend. We’ve hit the nail on the head with this...
Certifying your IoT device

Certifying your IoT device

Certifying your IoT device The CE Radio Equipment Directive 2014/53/EU (RED) certification only applies to the radio module and is not transferred to the complete circuit board with the enclosure.  You will have to test again, but only a subset of the tests...
Can you fit NB-IoT into a matchbox?

Can you fit NB-IoT into a matchbox?

Can you fit NB-IoT into a matchbox? We received a request for an NB-IoT device in a matchbox. It is of course not an actual matchbox but similar in size.  Small NB-IoT devices with batteries operating in the frequency range from 600 MHz to 1000 MHz are the premium...
NB-IoT throughput vs antenna gain

NB-IoT throughput vs antenna gain

NB-IoT throughput V antenna gain Because a picture is worth a thousand words, here is the NB-IoT throughput table in a graph. With a 144 dB link budget (all the power gains and losses from transmitter to receiver), we will achieve a speed of 21 kbps. If the link...
