IoT devices are mostly made of devices with low electricity and specifications. According to IoT characteristics, solution is required to efficiently manage many of the devices that use low bandwidth.
Especially, telecommunication business holders, IoT device manufacturers, and platform business holders have continuous interest in a new field, IoT industry, and many of them have adopted LwM2M, enacted by OMA as standard specifications, to manage IoT devices. Therefore, it is expected to help IoT business advance to global arena. Using such LwM2M, it is available to remotely manage various devices conveniently such as smart factory, smart grid, or smart home that IoT service providers or manufacturers are able to save cost, improve quality, and conveniently manage devices.
LwM2M (Light Weight M2M) 
Unlike OMA DM technology that is mostly applied on devices with high specifications such as smart phone, LwM2M is developed to manage devices with low electricity or specifications to be appropriate for IoT environment. Since standards were firstly made in 2017, telecommunication agencies such as AT&T in America, various IoT platform business holders such as Ericson, Huawei, NOKIA, or Telit, and IoT module manufacturers have adopted LwM2M as IoT device managing technology. Therefore, there has been an increasing trend of using LwM2M these days.
OMA is inappropriate to apply in IoT device environment with OMA DM that is device management standard for existing mobile devices. Therefore, standards have been enacted to be applied in all the IoT devices including devices with low electricity or specifications.
LwM2M is a standard specification applied in light-weighted devices by using CoAP protocol unlike other device managing standard specifications.

System Architecture
LwM2M is comprised of LwM2M server and LwM2M client for collecting and controlling IoT device data and updating and monitoring firmware. LwM2M is in a structure available to be compatible with various services of IoT. Therefore, it is a function specialized in IoT service.
Use Case
Firmware Update
It is available to update many of the IoT device firmwares using LwM2M specifications. According to LwM2M specification characteristics, it is available to minimize the N/W traffic in wireless areas making IoT devices maintain the up-to-date software. When updating, the size of files to be transmitted is reduced decreasing the amount of data to be used while applying FOTA technology. If FOTA solution is needed, it is available to provide additional FOTA solutions of KONA MOBILITY.
Terminal status monitoring
Monitoring the status of terminal on a real-time basis, error is notified to the server so that administrator checks the error in the user terminal and maintains the highest quality.
Data collection
Using basic CoAP protocol of LwM2M, it is available to collect, save, and process various types of information collected by IoT devices as well as to manage IoT devices.
Remote control
It is available to efficiently and remotely manage many of the devices as it is possible to remotely manage IoT device.
Reference
OMA holds an event named "Test Fest" to verify reliability on the quality realized by standard specifications, validate compatibility among many vendors of solution, and provide test environment one-one-one with vendors, and KONA MOBILITY regularly participates in important events to improve the compatibility of solution from the company and the completeness of technology. Based on the compatibility of global standards, they are applied to various IoT devices such as Smart Home, Smart Factory, or Smart City to make it feasible to efficiently manage the devices.
