Successful large-scale field-test of eSIM NB-IoT and LTE-M
iBASIS claims this represents the first successful massive field-testing of the LPWA cellular connectivity with a single eSIM. Users of Nordic products can now connect and monitor LPWA devices worldwide using iBASIS’ Open eSIM without requiring different SIM cards for each country. The two companies claim this is the first time a provider confirms standards-based cellular technologies are now ready for massive IoT deployments.
The tests were completed on a single GSMA-compliant eSIM card. Assessments were performed configuring Nordic’s nRF9160 SiP and Nordic Thingy:91 modems through the Nordic Link Monitor application. AT commands were used to switch between different networks and select/force different bands. AT commands also allowed switching betwee NB-IoT and LTE-M on the same board. Power Saving Mode (PSM) was tested, as well as IP-based data delivery in the core network together with data transfer optimization over the S11u interface for the NB-IoT use case.
This first phase of field testing was completed over six months for LTE-M and intensively over the past few months for NB-IoT. As a result of this successful phase, the connectivity solution is confirmed to be ready for general release at the end of September 2019.
