what is the difference between a walkie talkie and a 2-way radio?

A two way radio is also commonly called a transceiver, because it can both transmit and receive radio communications. In either case, the radio operates two ways; it can send and it can receive. A walkie talkie is a portable two way radio, particularly one that can be held in the hand.

If the walkie talkie works on a frequency of a CB radio, at 27 megahertz, then the walkie talkie can communicate albeit very limited. Higher priced and quality hand held radios tend not to pick up CB chatter because they broadcast on a higher frequency.

The main difference between the two mobile telephone systems (1G and 2G), is that the radio signals used by 1G network are analog, while 2G networks are digital . Main motive of this generation was to provide secure and reliable communication channel. ... During 2G Cellular phones are used for data also along with voice.

UHF radios broadcast at between 300 MHz and 3 GHz. VHF radio signals tend to degrade more than UHF signals indoors. UHF radios also have shorter antennas than VHF radios, making them a better fit for discreet radio devices or in situations where longer antennas are impractical, such as crowded hallways in schools.

A 2-way speaker has two types of drivers which are known as a woofer and tweeter. ... A 3-way speaker generates sound from three individual devices known as the mid-range, woofer and tweeter drivers.

Walkie talkies have loudspeakers that also acts as a microphone when you press the Push-To-Talk (PTT) button. You do this when you have to speak to the other people. ... Therefore, two-way radios work perfectly in mountains, forests, and other areas far from the city.

A 2-way speaker could very well produce a much higher quality sound than that of a 4-way speaker. A 2-way speaker with two high quality drivers will sound much better than a 4-way speaker with 4 cheap drivers. It may have a larger range of frequencies, but none of those ranges would sound any good.

Before cellphones became popular during the 1980s and 1990s, walkie-talkies were the most effective way to share information over short to medium ranges—and they're still widely used by police officers, military personnel, and the organizers of public events.

fm radio. FM transmission is analog. The quality is due to a better noise immunity of FM over AM. But you can modulate digital signals and send it over FM like you can send digital data over analog telephone line.

GMRS is UHF High band FM modulation. Better coverage overall in any of the UHF bands. CB is good for mobile to mobile talking ( I mean car to car). There also is a limitation on the amount of WATTS you can legally crank out of it.

Real walkie talkies aren't secure, Zello is. One-to-one and group conversations are fully encrypted end-to-end. Unlike real 2-way radios, Zello messaging is safe from anyone prying into your private discussions by intercepting a radio frequency. Messages are stored only on your own device, not on our servers.

GMRS is for people that want to use radios to communicate with each other. Ham is for the people that want to send and receive radio signals for the shear joy of seeing if they can. They each require separate licenses.

Ham radio is limited to certain specific frequencies (bands). Shortwave includes all the ham frequencies (below VHF and UHF) and all the frequencies in between. ... Shortwave is similar to a radio station, in that it is broadcast only. Ham radio is two-way communications, meaning a station can both transmit and receive.

FM signals are therefore transmitted by an FM radio station, and AM signals by an AM radio station. These two types of signals can both be picked up by an analogue radio. Digital radio is a form of radio that relies on digitally transmitted data, made up of ones and zeros.

With your 2 way speakers, you have just your woofer and tweeter. The 3 way speakers take those two and add a mid-range speaker. Your 4 way speakers are going to take all that and another tweeter. Consider them like leveling up when you start looking at different sound systems.
