On the unlicensed 869 MHz frequency band, there is a limitation in the duty cycle in Europe. Without Listen Before Talk, the channel can be used for transmissin for 36 seconds with 1 hour (1% of 3600 seconds) only. If a weather station wants to send its measured value every second, this leads to 10 […]
NB-IoT coverage in NL Ground Control to the #LPWAN shuttle: “Captain N.B. , Wow you leaked the NB-IoT secret of Dutch! Unbelievable, they run 4471 base station tranceivers in band 8 on 41,543 km2 surface. This is 0.929 km2 in average per BTS. This is the best LPWAN BTS density in Europe for sure. Over and […]
NB-IoT module on Arduino shield – text strings to USB Any akorIoT radio adapter consists of a cellular (NB-IoT module or other cellular module), a GNSS module and four sensors. In addition there is a SIM card. In summary there are seven serial interfaces to test. Our test software has 250 lines and two “include […]
Close to 100 German cities got NB-IoT coverage – Ground Control to the #LPWAN shuttle: “Captain N.B. you worked hard today. Within 24 hours, you made a basic scan of the LPWAN coverage in Germany. You found close to hundred cities with NB-IoT coverage. Please be so kind and provide us with some more details […]
As the captain of the space shuttle #LPWAN N.B boldly leads his crew to the outlying regions of the (mostly) nice blue planet called Earth where no man expected to find a wireless network before. Often, the recurring characters of S. and L.W. support him in reaching his mission goal on the proviso that they […]
Some people talk about IoT. My customer do IoT. In this case, it is an IoT device in metering again. The M-Bus Master Unit GSS-134 of Pikkerton is on Quectel GSM module M66 and got a replaceable battery pack. It can run easily without longer installation effort. M-Bus master interfaces: M-Bus Master Unit, 20 Standard […]
Deutsche Telekom AG has its NB-IoT network live in several major German cities (Berlin, Bochum, Bonn, Chemnitz, Dortmund, Duisburg, Düsseldorf, Erfurt, Essen, Gelsenkirchen, Cologne, Leipzig, Leverkusen and Mannheim. There are now no longer any obstacles to developing and using NB-IoT applications. akorIoT with NB-IoT + one of 33 STM32 Nucleo or Arduino UNO = your […]
What is the main difference between the order button concepts? The Amazon button is based on Wi-Fi and will run when connected to the home Wi-Fi network. It will only work over a short distance to the broadband WiFi router and you have to register it. The Gillette Order button is based on a cellular […]
Last week I got the request to support a small GPS tracker. The request is not new to me. It reaches me in several times per year. However, it makes no sense to reinvent the wheel again and again. To minimise the effort for your GPS tracking project on NB-IoT, LoRaWAN, SIGFOX or Weightless P […]
Date: Starts June 23 2017 at 8.00am / Ends June 24 2017 at 4.30pm Venue: @ hub:raum Winterfeldtstraße 21 10781 Berlin There will be an NB-IoT Hackathon in Berlin, Germany. 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 […]
