HARdunio – Arduino footprint NB-IoT shield update

Arduino shield with NB-IoT module

We have extensively tested the HARduino board over the past few days. We have been testing the GSM version due to the lack of NB-IoT coverage in the region of our office in the North of Germany but both NB-IoT and GSM exhibit the same characteristics in the tests we carried out. The AT command set […]

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 […]

Update IoT / M2M Cookbook, 3 hour Antenna Tutorial, IoT at Electronica in Munich

IoT M2M Cookbook

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 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 […]

Maybe the IoT does not make sense!

The Washington Post told us three reasons why the Internet of Things does not make sense. http://www.washingtonpost.com/blogs/innovations/wp/2015/01/16/3-reasons-why-the-internet-of-things-still-doesnt-make-sense/ With sense or without sense I have to quote out of my Cookbook. Since 25 years I’m in wireless data communication. We transmitted data out of cars with 3600 bit per second by FSK in private mobile radios. […]
