NB-IoT : Narrow Band Internet of Things

NB-IoT : Narrow Band Internet of Things Testing

IoTAS leading the way

 

If you are looking for NB-IoT testing, performed in accordance with the latest approved certification methodology then IoTAS has a solution for you.

In December 2017 IoTAS were certified by UKAS to to test NB-IoT devices and were the first GCF RTO to be accredited. In accordance with the stringent quality requirements dictated by the GCF it is mandated that any GCF Recognised Test Organisation (RTO) completing NB-IoT / Cat-M1 testing on behalf of a Manufacturer must have ISO 17025 Accreditation for GSMA TS.40/CLP.23, so if you want GCF certification then make sure you are dealing with a quality driven and assured provider.

In addition to this IoTAS were the first GCF RTO to complete Field Trial testing on Band 5 for an NB-IoT device at The Vodafone IoT lab in Newbury, UK, which is part of the GSMA Mobile IoT Initiative (Open IoT Labs). The testing was completed by IoTAS in accordance with the GSMA TS.40/CLP.23 field trials test specification.

 

Whether you are developing a product for Smart Metering, Smart Cities, Smart Buildings, Consumer based, Agricultural or environmental purposes IoTAS can offer you thorough, comprehensive 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.

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

IoTAS Field Trails – GCF NB-IoT / eMTC (F.5.4)

 

IoTAS have partnerships with CIoT network operators who, in turn, provide access to provisioned live network SIMs or test laboratories so that a CIoT device can be tested against the requirements of GCF-CC F.5.4. Accordingly testing can incorporate:

  • Control Plane CIoT EPS Optimsations
  • User Plane CIoT EPS Optimisations
  • User Data Performance
  • Cell Reselection
  • Handover (eMTC only)
  • PSM state
  • eDRX operation
