IoT Device Battery Life 10 Years !!! How is it possible? Battery life Calculation for NB-IoT Device. Energy is the most scarce resource for an electronic device and when someone designing it, he needs to optimize its operation so that it consumes minimum power. When a device has a regular power supply along with the battery backup, … Read more
Maximum Coupling Loss has been chosen by 3GPP as the metric to evaluate coverage of a radio access technology. In theory, it can be defined as the maximum loss in the conducted power level that a system can tolerate and still be operational (defined by a minimum acceptable received power level). MCL can be calculated … Read more
IoT nb1 vs nb2 Devices Comparison, Narrow Band IoT specifications were first introduced in 3GPP release 13 and then further enhanced in 3GPP release 14 with some essential features. Release 13 NB-IoT device category is referred to as Cat NB1 or Cat N1 and Release 14 devices are referred to as Cat NB2 or Cat … Read more
When an NB-IOT UE accesses a cell, it follows the same principle as for LTE: It first searches a cell on an appropriate frequency. Decode NPSS and NSSS for NCellID. After decoding NCellID, UE decodes the NB-MIB Information transmitted over NPBCH, but there it can get to know NB-LTE deployment mode i.e. In-band, Guard-band or Standalone, the schedulingInfoSIB1, … Read more
