-Eight IoT standards you should know-
Finally the long-awaited Narrowband IoT (NB-IoT) network is ready for roll-out in Copenhagen to begin with, and soon other Danish cities. NB-IoT is the telecommunications companies’ bid for wireless technology to be used for the Internet-of-Things (IoT) over long distances.
In recent years, a fierce battle has been fought to come first with the wireless communication standards that can be used to send data from IoT devices and further into the cloud. TDC is the first telecommunications company in Denmark to complete a new LPWA network dedicated to IoT, which is connected to the existing LTE network.
Chipsets and standards
The NB-IoT network offers speeds of up to 200 kbit/s, so images can not be streamed. On the other hand, battery consumption is so low that many devices will have a lifespan of up to ten years, as well as the price of data connections will (presumably) be low.
The new narrowband network also has a significantly longer range than the common mobile network – hence the name of the Low Power Wide Area. For example, TDC can cover the entire Copenhagen with 39 masts for narrowband IoT, while for a similar standard LTE coverage 350 masts will be used. The range is 10-15 kilometers per NB-IoT mast.
In Denmark, Aarhus Municipality has established a network with the open LoRa standard, as well as the energy company Seas-NVE retrieves data from 8,000 sensors on several dedicated LoRa networks. LoRa drives the unlicensed frequencies, and you must your self establish the network with own gateways. NB-IoT is considered to be the standard that becomes dominant in Europe because it is run by large telecom companies like Vodafone, Telia and Orange, which already operate LTE networks, and manufacturers such as Ericsson and Huawei.
