New GSM / GPS / Bluetooth module adapter for STM32 Nucleo, Arduino, Intel Galileo plus compatible PCBs Your ideas? Your wishes? Your recommendation? Your advice? I will listen to you. Before I started to write the IoT / M2M Cookbook I asked business friends what they would like to pay for such a book. A […]
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 […]
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 […]
GSM PIFA antenna flying over ground A picture can tell more than thousand words. I do not remember how often I have drawn such a sketch at a customer’s office. It is time to change this waste of time and to start with an antenna proposal gallery online. The GSM PIFA antenna is “flying” over […]
If you are in GPS tracking business and have customers or plans to deliver to Russia, then it makes sense to have a look on a combined GPS/Glonass module.
Wrong desigend GSM GPS Tracker The two yellow bars on the screen of the vector network analysers mark the – 6 dB return loss target for GSM 900 and GSM 1800. In the lower GSM 900 band the antenna is far away from the -6 dB. The GSM antenna is not an antenna. It is […]
By using of a combined FR4 together with Flex PCB is it possible to bend the PCB and to get a good ground plane for the GSM and GPS antenna. Such PCBs can be useful for tracking of animals, banknotes or tracking of security officers.
