The oldest delivery service in the world now obtains NB-IoT

The oldest delivery service in the world now obtains NB-IoT

The oldest delivery service is certainly Santa Claus. He has been delivering punctually to children for generations. Santa Claus lives in his factory at the North Pole. Santa’s helpers are the gnomes. They make gifts for the children. At Christmas Santa Claus packs all the presents on his sled. As we now, reindeers pull the […]

LoRa module 2400 MHz

LoRa-2400-MHz coverage

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. […]

Unlicensed like Icarus flying to the sun or licensed like Charon in the underground

LPWAN - flying to the sun

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 […]

The new benchmark in LPWA indoor penetration is underground

Estimated LoRaWAN cell size versus cellular BTS in Munich

Light indoor, indoor penetration and deep indoor 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 […]

Antenna matching service

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 […]
