Developers and start-ups are being called to disrupt today’s IoT landscape by creating services & solutions based on the NB-IoT technology. NB-IoT stands out due […]
Are we able to make a mint of money with such a low-cost BLE-GPRS-GPS-gateway? If yes then it makes sense to follow a train of thoughts listed in my IoT M2M Cookbook. Everybody can make such a gateway real for less than USD 15. In my IoT M2M Cookbook – excerpt here: http://www.gsm-modem.de/M2M/m2m_iot_cookbook I explained […]
The idea for the NB-IoT shield with Arduino header was conceived in summer 2016. We then produced the first version of the NB-IoT shield at the M2M Summit in September 2016. The second generation was shown to readers of my IoT/M2M Cookbook in our end of the year mailing and it has proved extremely popular; we […]
RF engineers already know that signal propagation characteristics vary according to frequency. In simple terms, signals carried at lower frequencies travel further. Since wavelength equals the speed of light divided by the period of the carrier signal, we can see that low frequency signals have a long wavelength. Long wavelength, low frequency radio waves are […]
IoT / M2M question by email to me: Q: Hi Harald,I found you on m2m.com forum discussion. I am an M2M enthusiast building an M2M PoC. I noticed in one of the m2m.com forum thread you suggested to Wakeup devices using SMS or Voice call. ie. Bootstrap to the GPRS network. I would like to […]
This Wi-Fi module arrived yesterday. The complete package includes the Wi-Fi module, a USB connector and a Serial Peripheral Interface (SPI) to USB converter. The operating voltage is supplied via USB from the PC. After plugging the module into the USB port, a standard terminal software application was started on the PC. With the first […]
New GSM / GPS / Bluetooth module adapter for STM32 Nucleo, Arduino, Intel Galileo plus compatible PCBs Your ideas? Your wishes? Your recommendation? Your advice? I will listen to you. Before I started to write the IoT / M2M Cookbook I asked business friends what they would like to pay for such a book. A […]
Year 2015 ended and year 2016 started with a big BANG in IoT and M2M. It was not just the firework display at the sky. In the last few weeks at the end of 2015 several rabbit conjure out of the hat: LTE module CAT 1 LTE module CAT 4 LTE module CAT 9 LTE […]
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 […]
