transmission
Let an agent explain signal transmission, relay media, techniques, limits and regulation from telecommunications and standards sources, describe the named forms and note the optical property sense, and distinguish transmission from reception, communication protocols, broadcasting as a service, mechanical transmissions and disease transmission.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain signal transmission, relay media, techniques, limits and regulation from telecommunications and standards sources, describe the named forms and note the optical property sense, and distinguish transmission from reception, communication protocols, broadcasting as a service, mechanical transmissions and disease transmission.
In telecommunications, the process of sending signals carrying information from a transmitter to a receiver over a channel, whether wires, optical fibre or free space, including radio broadcasting with techniques such as sound multiplex for stereo and multiple audio channels, optical wireless forms the registry aliases name such as free-space optical communication, visible light communication and laser communication in space, and historical telephotography, the transmission of still images over telephone lines; the alias light transmission can also mean the fraction of light passing through a material. Transmission is limited by bandwidth, noise and attenuation, as described by Shannon s theory, and radio transmission is licensed and regulated.
What it is for: Sending information over distance.
It can be explain media and techniques; relay limits and theory; describe named forms; relay regulation.
Distinguishing features
Channel-based
Noise and attenuation
Wired and wireless
Regulated spectrum
What it looks like
Antennas, cables, fibres, lasers and transmitters.
Physical character
Shannon capacity theorem: 1948 year
telephotography early service: 1920s note - wirephoto
ITU Radio Regulations: international spectrum rules note
How it is recognised
Sending signals from transmitter to receiver
Free-space optical communication, visible light communication, laser communication in space, light transmission, sound multiplex in broadcasting, telephotography
Reception captures signals; protocols define rules; broadcasting is a service; mechanical transmissions transfer power; disease transmission spreads infection
