Radiation Patterns and Total Radiated Power (TRP) tested yourself

Turn table and special antenna to measure radiation pattern

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, […]

Which embedded antenna to select for your LPWAN / NB-IoT module?

25x25x4 mm ceramic patch antenna for LPWAN

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 […]

Which embedded LTE antenna to select for your LTE module?

LTE chip antenna - SMT

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 […]

WyzBee – your IoT enabler

WyzBee board

WyzBee – your IoT enabler The WyzBee board of Redpine Signals includes a wireless module providing Wi-Fi, Bluetooth 4.1, and ZigBee connectivity. Moreover it holds a six-axis inertial sensors, an infra-red receiver, a debug port, push-buttons, LEDs, USB ports, and expansion connector. Last but not least there is a Dual Core MCU with memory, wired […]
