Internet of Things Case Study – Smart Parking

Internet of Things Case Study – Smart Parking – “Telemoritz” in Hanover

In Patras, Greece, developers are already working on a smart city technology development using NB-IoT. But how can they avoid the need for a SIM card and its subscription? Let’s consider the technical proposition. Technical needs Smart parking sensors are sending one status update message of 10 bytes two to eight times per hour. 30 […]

Internet of Things Case Study – Street lights

Internet of Things Case Study – Street lights - Power station in Hanover

In Patras, Greece, they work on smart city technology development using NB-IoT has started. But how can the developers avoid the need for a SIM card and its subscription? Technical needs The smart lighting controller, for example, has been sending one status update message of 40 bytes every five minutes and a message containing energy consumption […]

NB-IoT coverage in NL, 4471 BTS in band 8 – Captain N.B. episode 5

NB-IoT BTS on band 8 in Den Haag

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 […]

Close to 100 German cities got NB-IoT coverage – Captain N.B. episode 4

#LPWAN status scanned by Captain N.B.

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 […]

All in one wireless module =>NB-IoT (LTE-Cat-NB1), LTE-Cat-M1, GPRS and GNSS (GPS, Glonass)

NB-Iot, LTE-Cat-M1, GPRS, GNSS module on radio adapter with Arduino header

A dream came true. Within the last days, NB-IoT is moving in big steps. Orders for a new combined module on NB-IoT (LTE-Catt-NB1), LTE-Cat-M1, GPRS and GNSS (GPS, GLONASS) are welcome. If you miss NB-IoT or Cat-M1 for now, then just use the GPRS radio inside the module. Requests for data sheets, orders for samples […]

World’s first free and open IoT out of the box with NB-IoT module with Arduino header

NB-IoT-LTE-Cat-NB1-M1-Arduino-Shield

Many IoT / M2M Cookbook customers asked me for an evaluation kit within the last two years. I launched the first version during M2M Summit in September 2016. In February 2017 the multicellular version came true. The working name is HARduino because it has an Arduino R3 compatible UART interface. HARALD – ALD + duino […]

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 […]

When pigeons tweet – birds in IoT

Pigeons wearing wireless pollution-monitoring devices will report back via Twitter

Pigeons don’t tweet, they make cooing noises. They don’t wear backpacks either. Usually. Well, say hello to the new breed of backpack wearing, tweeting pigeons that might just save lives.   If you live in a city there’s a good chance you’ll be sharing it most days with a large number of pigeons. And generally […]
