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 […]
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 […]
Today I launched the IoT-University at Linkedin. I gave the group a strong direction to LPWAN SuBGHz, because is this frequency range it is not so easy to take an off the shelf antenna and to make the wearable IoT dream true. I will be glad if you will join the IoT University as well. […]
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 […]
In Germany, we have at least three companies, who plan to roll out an LPWAN. Two of them are on LoRa the other is on SIGFOX. One of the LoRa operators is backed by a big utility company. However, right now a standard IoT system integrator will not get access to the public LoRa networks […]
Does LPWAN in IoT have a clear direction? Origin post in November 2015. Now we are 12 months later and nothing has changed. “Just follow the signs”. We heard that all roads lead to Rome. In LPWAN, unfortunately, the roads lead in different directions: one path leads to Sigfox; The next way leads to LoRa […]
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 […]
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 […]
I got my hands on an Eddystone Beacon before its official release. Eddystone Beacon – physical facts Dimensions and weight: 30 mm diameter, 10 mm thickness, 7 grams Promised lifetime: 18 months (30 year shelf life) Range: 75 Meters with up to 120 Meters at maximum power Enclosure: Waterproofed with an option for custom tooling […]
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. […]
