In 2015 local residents in the German federal land of Lower Saxony collected between 10 and 37 kg of waste glass each. In the small city of Osterode, they recycled 37 kg whilst for some reason residents in the district of Vechta only managed 10 kg each – must try harder Vechta. Source: National Statistics […]
The new ultra-compact BC68 Narrowband Internet of Things (NB-IoT) module has same footprint as the M66 GSM/GPRS module. NB-IoT module features at a glance Dimensions: 17.7 mm × 15. 8mm × 2.3 mm Pin-compatible with GSM module M66 Frequency bands: B1, B3, B8, B20, B28 Communication speed: UL: 62.5kbps by multi-tone 3GPP release 14 […]
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 […]
The antenna is always the key to success for your wireless application. Each antenna has its benefits and drawbacks. The selection of the right antenna at beginning of a development project, or if you are planning the development of a device around the antenna, could save you a lot of money. A: Vertical polarised monopole […]
In 2016, a creative team in Frankfurt had the idea of developing an IoT push button for ordering goods via a cellular module. In principle, something similar to the Amazon Dash button, only using a GSM radio instead of Wi-Fi. A first, and a tricky learning curve for the engineering team. The developers in the […]
1. IoT buttons In my region, two IoT buttons caused a buzz and landed in the basket of end customers. One is the Amazon Dash button and the other one is the Gillette order button called Gillette Club Station. LoRaWAN and SIGFOX had no chance as carriers because of the lack of deep indoor coverage […]
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 only 36 seconds per 1 hour (1% of 3600 seconds). If a weather station wants to send its measured value every second, this leads to a […]
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 […]
