In the EU, the goal is to reduce greenhouse gas emissions by at least 55% by 2030. Buildings significantly contribute to greenhouse gas emissions, as almost 75% of the EU’s building stock is currently energy inefficient. In an inefficient building, much energy is wasted; it goes up in smoke. The figure is also high globally, …
Recently I attended an event by Proptivity, a company that wants to take 5G coverage indoors. The coverage should not be provided by outside base stations, but rather by indoor “spots” that will increase 5G coverage indoors in buildings. The clever idea is that is not a repeater solution per se, it is a distributed …
IoT has been the same as LPWAN, Low Power Wide Area Networks for many people. Sensor networks with millions of connections. Sensors that can run off batteries for years send small data packages with sensor data now and then. For years I have had another view of IoT, which is why I most of the …
Great news, I am now a part of the IoT Alliance of Eutech as a board member. Eutech, The European Technology Chamber, is a non-profit organization on a mission to enable European businesses to use technology to benefit Europe and humanity. Eutechs core value and vision is Technology Obliges. EUTECH is committed to bringing people …
NB-IoT can be implemented in three ways: standalone, guard band and in-band. NB-IoT standalone operation Standalone: NB-IoT channel used outside the 4G/5G spectrum, for example, the spectrum used for GSM or satellite communications. Standalone operation is when NB-IoT is used exclusively within a spectrum, whether in a private or public network. This model provides the …
NB-IoT is designed to achieve a 20 dB coverage improvement over GSM’s MCL or link budget. The maximum link loss, MCL, for GSM is 144 dB. The maximum link loss for NB-IoT is, therefore, 164 dB. There are several ways that NB-IoT improved the signal over GSM. NB-IoT and Message repetition The downlink improvement is …
For NB-IoT, the general design goal of the 3GPP standard is that the battery should last for at least ten years. NB-IoT reduces power consumption using mechanisms called eDRX and PSM. The eDRX (extended Discontinuous Reception) and PSM (Power Saving Mode) parameters allow the device to go into a deep sleep mode for a few …
NB-IoT is one of two 5G LPWAN standards (the other is called LTE CAT-M1). NB-IoT and LTE-M have excellent energy consumption and power-saving features; they are great for saving a lot of energy compared to other cellular standards. There are different technologies and functions within each of these two to do that. If you have …
I am continuing with the eighth post in my series LoRaWAN vs 5G. As I was speaking about 5G at a LoRaWAN event (ThingsConference 22nd of September 2022), I found it appropriate to dig into the aspects of LoRaWAN vs the current 5G standards for LPWAN. In the last post, we compared the cost of …
IoT is democratising. I spoke about that in my last keynote at the Things Conference. IoT can be an excellent resource for gathering data. Data from sensors or trackers, or a combination of sensors and trackers. Data can be transmitted via your private LoRaWAN network or your 5G LPWAN operator. The data can be collected …
