Which two foundational aspects of loT are still evolving and being worked on by the industry at large? (Choose two)

WiFi protocols for IoT environments, including 802.11ah (Wi-Fi HaLow) designed for sub-1-GHz long-range and low-power operation, were under active development and standardization to meet the unique demands of IoT deployments.

Regulatory domains are defined and enforced by national and international government bodies such as the FCC and ETSI - they are not a technology being actively evolved by the industry at large.

Bluetooth Low Energy sensor technology was being continuously evolved with new profiles, mesh networking capabilities (Bluetooth Mesh), and lower energy consumption specifications to support diverse IoT sensor use cases.

IoT consortia such as the Open Connectivity Foundation (OCF) and the Industrial Internet Consortium (IIC) are established organizational structures, not themselves a foundational technical aspect still under active development.

While specific IoT standards continue to mature, the question targets the lower-level wireless communication technologies that form the active frontier of industry development rather than standards bodies and processes.
