This standard specifies Physical (PHY) and Media Access Control (MAC) layers of a broadband powerline communication technology for Internet of Things applications (IoTPLC) based on wavelet Orthogonal Frequency Division Multiplexing (wavelet OFDM). This standard defines modes for operations in different channels (frequency bands) with different values of carrier spacing. IoTPLC can be used for wired communications via any type of physical medium such as but not limited to electric power lines and coaxial cables. This standard uses transmission frequencies below 100 MHz. This standard addresses the necessary security questions to ensure the privacy of communications between users and allow the use of IoTPLC for security sensitive services. One communication channel defined in this standard interoperates with IEEE 1901. For other channels this standard coexists with IEEE 1901 using IEEE 1901 Inter-System Protocol (ISP) and 1901.2.
