Narrow Band IoT (NB IoT)

Narrow Band IoT (NB IoT)

NB-IoT, unlike other M2M wireless solutions, is a radio which is able to co-exist with LTE (Cellular technology). As well as co-existing with cellular technology NB-IoT will also benefit from the security and privacy mobile network features, which include;


  • User identity confidentiality
  • Entity authentication
  • Data integrity
  • Equipment identification


The technology has been optimized for simple, low-end devices which means that component costs are kept to a minimum. As well as being cost efficient products will have low power consumption allowing a products battery life to last up to 10 years.


NB-IoT was designed in a way that only small packets of data are sent intermittently so there is no requirement for high throughput speeds. NB-IoT delivers downlink speeds of around 50 kbps and uplink speeds of 20 to 50 kbps in a bandwidth of 180 kHz.


There are three operational modes which are available:

  • In-band – implemented within an LTE carrier
  • Guard-band – deployed in an LTE guard band
  • Stand-alone – to be used on re-farmed 2G spectrum


Whether you are developing a product for Smart Metering, Smart Cities, Smart Buildings, Consumer based, Agricultural or environmental purposes IoTAS can help you with your testing. IoTAS are able to complete GCF Field Trial testing for NB-IoT as well as completing confidence level testing against our own test plan.
