Radio

The radio (wireless not to be choked on) is a method, a method not to use the line.

I am added as prefixes by a modified word and constitute a compound word. As a result, "the radio" often points to the radio telecommunications soon because I am shortened frequently, and "radio telecommunications" (or "wireless communication") is merely called in particular "radio".

Summary

They distinguish it simply because both type cabled is used together with radio, and "radio" and the thing adorning are rare expressly when there is only a method not to need the line. For example, in other words, it is a sound, a beacon, the lighthouse of a meeting conversation, a bell and the cannon specifically, but the transmission line does not use the information for an away partner by these means when I transmit a sound and light by the method except telecommunications (the same without converting it into an electrical signal) when I tell. However, there is not usually that I call it with "radio" (or "wireless communication" "radio sound transmission") because the cabled method that you should compare does not lay an extremely limited thing (but a sound is not same, and speaking tube and thread telephone - this convert it into vibration and communicate -), and it is not necessary to distinguish it.

Because the means that put the wireless communication of the electrical signal to practical use was ever only electric wave (radio), there is it at the time written in the Japanese dictionary like "the radio is the communication that used an electric wave". However, the expression called "light wireless communication" to be opposed came to be often used as in late years cabled optical communication was put to practical use by the fiberoptic spread.

The circumstances are the same about English wireless and mean, "there is not a wire", but are often abbreviation of the wireless communication (Wireless Communication) when they say only merely wireless. The communication with the wireless communication machine is mainly imaged, for example. The cordless microphone does the communication by an electric wave or infrared rays after I convert a sound into an electrical signal.

In addition, in the case of a brassiere, I call even expression to mean that there is not a wire "a non-wire".

"Radio" that I point

• Wireless communication (or radio telecommunications). It is communication to use an electric wave and the light (including infrared rays) for without using the line. For the synonym in this meaning with "radio lei Dio, a radio" (radio means electric wave-style wireless communication in particular, and the electric wave receiver is called radio receiver or radio receiving set in English)
  • Amateur radio communications, ship radio, aviation radio, train radio, the vehicle radio of the bus, wireless LAN (Wi-Fi).
  • The abbreviated designation of the radio taxi (taxi performed the allocation of cars, use of using a radio machine systematically).
  • Turn; and a part of the store's name, the company name of the electric appliance shop (Sato Musen). In Japan of the 1950s, the radio (electric wave receiver) was a main handling product of the electric appliance shop. It comes from above-mentioned circumstances that the "radio" and "radio" / "radio" is used for the name of the electric appliance shop from old times.
• An object of the transmission is the thing except the communication signal, and there is an example of "the wireless electricity transmission".
• I integrate a power supply into stun gun - projectile of the type to fire a wire needle, and there is the thing which lost a wire for the power supply.
• It is the unsewn binding that is one of the forms of the bookbinding.
• Others, example except the transmission purpose
