The Amateur Radio bands above 50 MHz can support computer-to-computer communications at speeds high enough to support multimedia applications. Multimedia in this case refers to voice, data and image communications. Hams call this HSMM—high speed multimedia.

One approach that has been extensively explored is the adaptation of IEEE 802® technologies, particularly 802.11b operating in the 2400-2450 MHz band, known as the "Hinternet."

John Stephenson, KD6OZH has tested an orthogonal frequency division multiplex (OFDM) system on  the 6M band.
