Wireless Congress: Systems & Applications 15th. November 2018, Munich, Germany Time: 16:00 – 17:00 Session/Workshop Speaker: Harald Naumann, tekmodul Language: English Registration (soon): https://www.wireless-congress.com/home.html The wireless Internet of Things has a need for inexpensive wireless modules and antennas. An NB-IoT module will cost less than US$ 6 at 1K order. A self-made NB-IoT antenna on […]
Wireless Congress: Systems & Applications 14. November 2018, Munich, Germany Time 17:00 – 18:00 Session/Workshop Speaker: Wilhelm Oelers, Triptec HL UG Language: English Registration (soon): https://www.wireless-congress.com/home.html Title Make your hands dirty on NB-IoT application NB-IoT is the new shining constellation on the LPWAN sky. It stars are called low energy consumption, low price, small sized […]
NB-IoT reference design in credit card size including PCB track antenna The wireless IoT market is crying for small mobile devices transmitting for years from tiny batteries. With akorIoT Nano we developed the next open design. “akor” is the Proto-Celtic word for “open”. With placing the order for akorIoT Nano you get the schematic diagrams, […]
The antenna design in this LoRa-Tag is based on the application note for the Texas Instruments DN038. The customer’s project objective was to match the antenna to the European 868 MHz band without changing the structure. Text excerpt from the TI application note “There are several ways to tune an antenna to achieve better performance. […]
1. IoT buttons In my region, two IoT buttons caused a buzz and landed in the basket of end customers. One is the Amazon Dash button and the other one is the Gillette order button called Gillette Club Station. LoRaWAN and SIGFOX had no chance as carriers because of the lack of deep indoor coverage […]
Last week I got the request to support a small GPS tracker. The request is not new to me. It reaches me in several times per year. However, it makes no sense to reinvent the wheel again and again. To minimise the effort for your GPS tracking project on NB-IoT, LoRaWAN, SIGFOX or Weightless P […]
Are we able to make a mint of money with such a low-cost BLE-GPRS-GPS-gateway? If yes then it makes sense to follow a train of thoughts listed in my IoT M2M Cookbook. Everybody can make such a gateway real for less than USD 15. In my IoT M2M Cookbook – excerpt here: http://www.gsm-modem.de/M2M/m2m_iot_cookbook I explained […]
I can carry my light antenna radiation pattern test system by car, train or aeroplane. The test reports have the same accuracy like with an electronic chamber. The main difference is price and size. The mobile antenna radiation pattern system is much smaller and cost Euro 14,000 only. To install a chamber will charge much […]
Calibration of the VNA on PCB with embedded antenna The calibration of the VNA (Vector Network Analyser) for a PCB with embedded antenna is difficult. The final antenna with all components except the wireless module should be mounted inside the final enclosure. The wireless module will be replaced by the probe. The three calibrations of […]
