I have an (IoT) dream – Tesla in front of Burger King I took this photo on my business trip on Monday to an electric vehicle charge station. On the way back to my home I got tired and decided to stop, take a nap and to get some coffee. I left the highway and […]
Today we tell you the ingredients you will need in order to reproduce the world’s first IoT sandwich. The sandwich is planned as a starter. We will show you how to make the main course and the dessert later. Ingredients for the IoT sandwich For the PCBs 9 different PCB shapes (3 different cut-out zones […]
The device under test is a PCB of size of 40 mm x 20 mm with GNSS antenna for a small tracking device again. The first DUT in this series of test is listed here. Small mobile GSM / GPS trackers are common for pets, humans or assets. Chip antennas operate as loop antennas which […]
The device under test is a PCB of size of 40 mm x 20 mm with GNSS antenna for a small tracking device. Small mobile GSM / GPS trackers are common for pets, humans or assets. Chip antennas operate as loop antennas which are magnetic antennas and are usually unaffected by being near to the […]
For a few bucks you can get such a Radiation Measurement System (RMS) to measure Radiation Patterns and Total Radiated Power (TRP) from a 3-axis rotation of your wireless IoT / M2M application. While Radiation Patterns and Total Radiated Power (TRP) is usually measured in an anechoic chamber to avoid reflections to affect the measurement, […]
Wireless IoT is a big dark forest with a lot of trees. This time I have chosen symbolic the LTE-tree. All leaves of the tree you can touch at Embedded World booth 5-139. Additional to the tree for LTE there is one for GPS / Glonass, Wi-Fi, Bluetooth Low Energy, LoRa, ZigBee and a lot […]
Embedded LPWAN & NB-IoT antenna consideration On first quick look the choosing of the right integrated antenna for LPWAN & NB-IoT looks easy. In comparison to the large number of LTE bands the selection is simple because LPWAN (e.g. LoRaWAN, Sigfox, Weightless N) and NB-IoT (EC-GSM and NB-IoT) are on 900 MHz. There is no […]
Year 2015 ended and year 2016 started with a big BANG in IoT and M2M. It was not just the firework display at the sky. In the last few weeks at the end of 2015 several rabbit conjure out of the hat: LTE module CAT 1 LTE module CAT 4 LTE module CAT 9 LTE […]
Before the year comes to an end there is a need for a birthday cake on my desk. This is because I have been working in GSM and GPS for 20 years. What has happened in those 20 years? GPS GPS have modules achieved lower and lower power consumption. Today we are at 5 mA […]
Embedded LTE antenna consideration Choosing the right integrated LTE antenna is not easy. The large number of LTE bands makes the construction of integrated LTE antennas more complex. All that glitters is not gold. You have to look closely at the data sheet of the LTE antenna. The lowest LTE frequency is 698 MHz. The […]
