The comparison of the range of a LoRa module with 2400 MHz, Bluetooth long range modules and LoRa 868 MHz modules shows that BLE long range is not a real long range. LoRa 2400 MHz with SF12 is not much worse than LoRa 868 MHz. LoRa 2400 MHz is not subject to any duty cycle. […]
Icarus wanted to go high up unlicensed. If you don’t follow the rules like Icarus, then the fall comes after the flight. Icarus melted the wings. Why do the unlicensed LPWA companies of all firms repeatedly report hot-air balloons or weather balloons with extreme ranges and fly towards the sky and the sun? Up there […]
In part one of the tests, we fled the summer heat into a Munich subway tunnel. We had already announced the test at the eye level of a small terrier, the larger German shepherd and the insde of a ladies’ handbag. As good engineers, my colleagues in Munich always seek the most extreme tests and […]
Light indoor penetration and deep indoor penetration with LPWAN is yesterday’s news. The new record for the penetration through walls and floors was achieved in Munich on August 10, 2018 with NB-IoT. Due to the great heat in the office, our Munich team continued the NB-IoT tests in the Munich subway tunnels. With NB-IoT you […]
As the question about the costs and the procedure for the matching of antennas frequently occurs, we have described the process and explained it with some examples of projects. To estimate the costs, the answers to the following questions are necessary. Standard questions on antenna matching: Which radio modules were used? How many radio modules […]
SIM on chip or eSIM cards do the exact same job as a normal IoT SIM card. Neverthelesss, eSIM cards are permanently stored inside a device. An eSIM is usually attached by soldering to the PCB. eSIMs prevent people from tampering with the device or changing the device it sits in. This helps enhance the […]

As Freddie Mercury sang: “The show must go on”. After our Successful NB-IoT Roadshow with stops between Berline and Vienna in 2017, we return to Berlin on June 28th. “Berlin ist eine Reise wert” (“Berlin is well worth a visit”). June 28th is a Thursday. so anyone who will can take Friday as a day […]
