LPWAN comparison – Weightless-P vers SIGFOX vers LoRa

Sigfox, Lora, Weightless P compared to each other

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 […]

Comparison of LPWAN like SIGFOX, LoRaWAN, Weightless P and NB-IoT/LTE-Cat-NB1 – Tuesday, March 14, 2017


Tuesday, March 14, 2017, I will compare LPWAN like SIGFOX, LoRaWAN, Weightless P and NB-IoT/LTE-Cat-NB1 at embedded world in Nuremberg. Tuesday, March 14, 2017, 09:30 – 12:30 Session 03/I Connectivity – Wireless Technologies I Program: 09:30 – 10:00 Comparison of LPWAN Like SIGFOX, LoRaWAN, Weightless P and NB-IoT/LTE-Cat-NB1 Harald Naumann, Tekmodul 10:00 – 10:30 […]

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 […]

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 […]

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


I found the question “Is Sigfox / LoRa the new WiMAX?” on the Nokia networks blog: 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 […]
