For comparison, the Hata Model was used. Hata is the most widely used radio frequency propagation model for predicting the behaviour of cellular transmissions in built up areas. Settings for the simulation on Hata model LPWAN Base Station Height = 30m End-Device Height = 0.5m Simulation results for LPWAN on Weightless P, LoRa and SIGFOX If […]

What is NB-IoT? Lesson 1
Fundamentally, there really is no such thing as “NB-IoT”. The correct term is “LTE Cat NB1”. This technology is sometimes confused with Cat-M, which is another misnomer. The correct name for “Cat M” is LTE Cat M1. Both these technologies, LTE Cat NB1 and LTE Cat M1 are just subsets of “classic LTE” and are […]
Antennas tests – preparing a PCB for a device in the Internet of Things
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 […]

Antenna Tutorial -Self-made PCB antenna for NB-IoT and GSM for cost US$ 0
Self Made Embedded Antenna Design versus Chip Antenna The wireless Internet of Things has a need for inexpensive wireless modules and antennas. An LTE-Cat-NB1-module (NB-IoT) will cost less than US$ 6 at 1K order. A self-made NB-IoT antenna on PCB could cost US$ 0. Within 60 minutes you will learn which is commercially and technically […]
Update IoT / M2M Cookbook, 3 hour Antenna Tutorial, IoT at Electronica in Munich
This quarter I have a lot of IoT / M2M news for you: 1. Update IoT / M2M Cookbook Since 4 weeks the update is on the server, listed here: http://www.gsm-modem.de/M2M/m2m_iot_cookbook/ More than 12 pages are related to ceramic chip loop antennas for GPS/GLONASS and Bluetooth. Loop antennas have no hand effect and will not […]
Is it possible to use iBeacons / BLE beacons for triangulation or BLE indoor localisation?
Please find another close the same messages or questions on BLE indoor localisation to me as below. I get the question again and again at least once a month. It is time for a block post on this topic. What is the recommended way to implement BLE beacons to perform indoor localisation? What is the […]
