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 […]

Is Sigfox / LoRa the new WiMAX? – A comparison to LTE-M and NB-LTE

LPWAN versus LTE-M / NB-LTE

I found the question “Is Sigfox / LoRa the new WiMAX?” on the Nokia networks blog: https://blog.networks.nokia.com/mobile-networks/2015/10/21/is-sigfoxlora-the-new-wimax/ From hype to niche technology The subtitle of Nokia’s blog post was ”From hype to niche technology”. What is your opinion? Will we see wireless hype again? Sigfox and LoRa are LPWAN (Low Power WAN) technologies. Sigfox and […]

The Tower of Babel has a new name – LPWAN (Low Power WAN)

Tower of Babel

Tower of Babel LPWAN SigFox: SigFox has already deployed a few public radio networks. Nevertheless, there are none in Germany which blunts its argument as being ready to support applications. LPWAN LoRa: In my opinion, there is no single LoRa today. There are quite a lot of LoRa dialects and these dialects are as different […]
