  One of the important consideration in IoT is the capabilities of IoT device to run with a low battery consumption. This will increase the operational period of the device, lowering the maintenance demand, and at the end lowering the cost. Some of the Low Power Wide Area Network (LPWAN) technologies like NBIOT and LTE-M has widely known has this capability. They deliver this advantage is with protocol innovations to the standard that enable edge devices to communicate with cellular networks in a variety of different way. One of the example is eDRX or Extended Discontinuous Reception and PSM or Power Saving Mode. eDRX Introduced by 3GPP in Release 13, eDRX is an extension of the DRX feature that is used by IoT devices to reduce power consumption. It’s a mechanism in which a device goes into sleep mode for a certain period and then wakes up after a fixed interval to receive signals. The basic principle for eDRX is to extend DRX cycles to allow a device to remain in a power-savi...

  Subscriber Identity Module (SIM) has become de-facto way to authorize mobile device to Mobile Network Operator (MNO) network. Starting as plastic card as it’s physical form, SIM has evolved in some stages from regular, micro, nano, and now it has another form as eUICC SIM (eSIM). Plastic SIM works well for consumer devices and many IoT devices as long as it works in normal temperature environment. When it come with IoT devices there are some challenge that plastic SIM need to overcome. §   IoT devices deployed globally and it need to switch MNO connectivity with better coverage in terms of quality. §   IoT devices need to avoid roaming restriction. §   IoT device connectivity need tobe easily managed and maintained, even if it is located in far distance location. §   We need to move away from complexity of physical SIM logistic and management.   One benefit of eSIM that it can contain more than one MNO profile which required for network auth...
