Many customers always confused on these terms during two way radio , walkie talkie and radio. Don’t u ?
Different countries have different meaning between two way radio and walkie talkie , like US, it is no difference for the terms. Usually, the customer was searching two way radio , but he entered into the listed about walkie talkie , maybe he thought it is wrong website,not the same as two way radio.So for many different countries,maybe walkie talkies and two way radios are not the same .
Technically speaking, the two are not the same thing, although in some cases, they can be.
Two way radio.
In general. For hand-held two-way radios, see Walkie-talkie.
Several modern two-way hand-held radios compatible with the Project 25 digital radio standard (Mobile and base station radios not shown)A two-way radio is a radio that can both transmit and receive (a transceiver), unlike a broadcast receiver which only receives content. A two-way radio (transceiver) allows the operator to have a conversation with other similar radios operating on the same radio frequency (channel). Two-way radios are available in mobile, stationary base and hand-held portable configurations. Hand-held radios are often called walkie-talkies, handie-talkies, or just hand-helds.
Two-way radio systems usually operate in a half-duplex mode; that is, the operator can talk, or he can listen, but not at the same time. A push-to-talk or Press To Transmit button activates the transmitter; when it is released the receiver is active. A mobile phone or cellular telephone is an example of a two-way radio that both transmits and receives at the same time, ie in full-duplex mode. Full-duplex may be achieved by the use of two different frequencies or by frequency-sharing methods to carry the two directions of the conversation simultaneously.
Walkie talkie:
A walkie-talkie (more formally known as a handheld transceiver, or HT) is a hand-held, portable, two-way radio transceiver. Its development during the Second World War has been variously credited to Donald L. Hings, radio engineer Alfred J. Gross, and engineering teams at Motorola. First used for infantry, similar designs were created for field artillery and tank units, and after the war, walkie-talkies spread to public safety and eventually commercial and jobsite work.
A walkie-talkie is a half-duplex communication device; only one radio on the channel can transmit at a time, although any number can listen. The transceiver is normally in receive mode; when the user wants to talk he presses a “push-to-talk” (PTT) switch that turns off the receiver and turns on the transmitter. Typical walkie-talkies resemble a telephone handset, possibly slightly larger but still a single unit, with an antenna mounted on the top of the unit. Where a phone’s earpiece is only loud enough to be heard by the user, a walkie-talkie’s built-in speaker can be heard by the user and those in the user’s immediate vicinity. Hand-held transceivers may be used to communicate between each other, or to vehicle-mounted or base stations.
Radio:
Radio is the use of radio waves to carry information, such as sound, by systematically modulating some property of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width.When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.
Radio systems need a transmitter to modulate (change) some property of the energy produced to impress a signal on it, for example using amplitude modulation or angle modulation (which can be frequency modulation or phase modulation). Radio systems also need an antenna to convert electric currents into radio waves, and vice versa. An antenna can be used for both transmitting and receiving. The electrical resonance of tuned circuits in radios allow individual stations to be selected. The electromagnetic wave is intercepted by a tuned receiving antenna. A radio receiver receives its input from an antenna and converts it into a form usable for the consumer, such as sound, pictures, digital data, measurement values, navigational positions,etc.Radio frequencies occupy the range from a 3 kHz to 300 GHz, although commercially important uses of radio use only a small part of this spectrum.
A radio communication system sends signals by radio. The radio equipment involved in communication systems includes a transmitter and a receiver, each having an antenna and appropriate terminal equipment such as a microphone at the transmitter and a loudspeaker at the receiver in the case of a voice-communication system.
Conclusion:
Now that we’ve defined the terms, do u think are these terms interchangeable? Well, yes and no.
According to the definition, radio including the walkie talkie and two way radio, a walkie talkie is a two way radio, but a two way radio is not always a walkie talkie.
Do you consider walkie talkies and two way radios different or the same things? How and why? It’s a great topic and Let us know your idea ! Join us and give us your comments, much surprise waiting for you !
