Miniature Helical PCB Antenna for LoRa-Tag

LoRa Tag antenna 3D drawing

The antenna design in this LoRa-Tag is based on the application note for the Texas Instruments DN038. The customer’s project objective was to match the antenna to the European 868 MHz band without changing the structure. Text excerpt from the TI application note “There are several ways to tune an antenna to achieve better performance. […]

If you are planning to deploy your own LPWA network then you’ll need to understand a few things about RF signal propagation, run a few models and then conduct a few tests in the real world. In this article, we are going to explore what is involved so fasten your seat belts and let’s go… […]

NB-IoT networks worldwide 2017-11-1

LPWAN exception

NB-IoT networks worldwide In nominal data, 15 economies would have GDP above $1 trillion, 62 have above $100 billion and 177 have above $1 billion. Top five economies account for approximately 53.82 %, whereas top ten accounts for approx. 67.19 %. top 20 economies add up to over 80%. 92 smallest economies only contribute 1 […]

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 […]

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 […]
