Broadcast radio transmission involves the dissemination of audio signals over large areas using electromagnetic waves, allowing multiple listeners to receive the same signal simultaneously through radio receivers. In contrast, cellular radio transmission utilizes a network of interconnected base stations to facilitate two-way communication between mobile devices, enabling more personalized and direct connections. While broadcast radio is typically one-to-many, cellular radio operates on a one-to-one basis, providing greater flexibility and mobile connectivity for users. Both mediums rely on radio frequency but serve distinct purposes in communication.

The form of broadcast radio widely used for mobile communications, particularly in wireless modems and telephones, is known as cellular radio. This technology allows for the transmission of voice and data over a network of radio cells, enabling seamless communication across vast areas. Cellular radio employs various frequency bands and modulation techniques to ensure efficient and reliable communication for mobile devices.

This is amazing. "Wireless" obviously means "without wires", so cellular, broadcast,and microwave are plainly wireless. But before jumping at an answer, I went onlineand looked for a definition of "wire". Here's what I found:strand of metal: metal in the form of thin flexible strands, or a single strand of itmetal strand carrying electric current: a strand of metal, usually copper, that is encased in plastic or another insulating material and is used to carry an electric currentmesh structure: a mesh made of strands of metal, or a structure made of the mesh, e.g. a fenceDo you see what I see ? Each of those definitions mentions "metal", and that meansthat if the conductor is not metal, then it's 'wireless'.You'd have to include fiber-optic cable in that category then, because the conductoris glass.So none of the items on your list is 'not a wireless transmission medium'.

The transmission power requirement of a digital transmission scheme can be reduced by the use of an error control codec. This aspect is exploited in the design of most of the modern wireless digital communication systems such as a cellular mobile communication system by: Neha
On December 12 1901, a radio transmission received by Guglielmo Marconi resulted in the first transmission of a Transatlantic wireless signal (Morse Code) from Poldhu, Cornwell, to St.John's, Newfoundland.

There are a number of companies that lease cellular transmission towers. In the U.S., Crown Castle, American Tower Corporation, and SBA Communications are the largest companies. Wireless Infrastructure Group (WIG) has the largest portfolio of sites in the U.K.
