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 …
5G for Properties was an event by Ericsson and Proptivity, it was arranged at Ericsson HQ in Kista. I had a 15 min keynote, the topic was Inbuilding IoT – Today and Tomorrow. Watch the video from my Keynote here: Download my presentation
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 …
Right now, at the dawn of the global rollout of 4G networks, the term 5G has started to appear, although it has yet to be defined. Opinions are divided on whether the term 5G will ever be standardized. Within a decade, 5G networks could be on the way, at least if you look at 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 …
I am continuing with the seventh post in my series LoRaWAN vs 5G. As I was invited to speak 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.

I am continuing with the sixth post in my series LoRaWAN vs 5G. I was invited to speak about 5G at a LoRaWAN event (ThingsConference 22nd of September 2022), and this post will be published after the event. To be prepared, I found it appropriate to dig into the aspects of LoRaWAN vs the current …
