The document discusses the challenges and standards for remote device management of IoT constrained devices, emphasizing the need for easy updates to software and firmware due to deployment in remote areas. It highlights the lack of existing industry standards for management of M2M/IOT devices, and introduces the OMA Lightweight M2M (LwM2M) as a new standard being developed. The document also mentions various open-source implementations and the upcoming demonstration of 'devicepilot' for end-to-end remote management.
