NB-IoT shield with Arduino header renamed to akorIoT

NB-IoT Shield Arduino

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 […]

NB-IoT and band 70 – What is your opinion?

Radio wave lambda

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 […]

Wi-Fi module – five minute set up

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 […]

Low Cost GSM GPS Bluetooth module on Arduino shield

GSM GPS Bluetooth module as a glance

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 […]

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 […]

WyzBee – your IoT enabler

WyzBee board

WyzBee – your IoT enabler The WyzBee board of Redpine Signals includes a wireless module providing Wi-Fi, Bluetooth 4.1, and ZigBee connectivity. Moreover it holds a six-axis inertial sensors, an infra-red receiver, a debug port, push-buttons, LEDs, USB ports, and expansion connector. Last but not least there is a Dual Core MCU with memory, wired […]
