NEWS: LoRa vs SigFox news note and SigFox problems

Although I have already wrote about connectivity options for IoT systems and also about Lora vs SigFox, here I would like to link to another very good and brief article from Link-labs. The article compares SigFox and LoRa, two of the most prominent players in the unlicensed LPWAN market. SigFox chips and modules are made by several manufacturers and they are quite low cost, but the network and backend is totally owned by SigFox or the appointed SigFox operator which is good since allows roaming and bad since you have only one option. On the other hand LoRa is made…

What is NB-IoT?

NB-IoT stands for “NarrowBand Internet of Things” and it’s low power wide area (LPWA) cellular radio access technology standardized by 3GPP with aim to enable a wide range of IoT devices and services. 3GPP has defined a set of frequency bands for NB-IoT use: Release 13 list consists of bands: 1, 2, 3, 5, 8, 12, 13, 17, 18, 19, 20, 26, 28, 66 and Release 14 added the bands: 11, 25, 31, 70 and by Release 15 we’ll have additional bands: 4, 14, 71. There are three deployment modes specified by 3GPP: LTE in-band mode, LTE guard-band mode and…

Connectivity solutions for IoT

There are many very different IoT applications today from soil sensors that send a few bytes every few hours, up to the driverless car that sends many Megabytes of data constantly. Many if not all these applications depend upon good connectivity, but a question arises…what is a good connectivity for IoT? When planning IoT networks there are three major factors to pick from and these are power consumption, range and bandwidth/data rate. If your sensors can connect to a stable power source then it’s quite easy to reach good range and bandwidth, but in most applications this is not the…
