What are two of the differences between a walkie talkie and a cell phone?
The primary difference between two way radios vs. cell phones is who and how many individuals you can communicate with at once. A cell phone is a one-to-one communication device, whereas two way radios are one-to-many communication devices.
What is it called when only one person can talk at a time?
Selective mutism is a severe anxiety disorder where a person is unable to speak in certain social situations, such as with classmates at school or to relatives they do not see very often. It usually starts during childhood and, if left untreated, can persist into adulthood.
Can Walkie Talkies be hacked?
For officers and others in public safety and security who depend on their two‑way radios as a lifeline, the news that they can be hacked can be very disturbing. There’s no magic formula, but even as hacking increases, the technology designed to keep frequencies secure and safe is evolving.
Is walkie-talkie a phone?
Typical walkie-talkies resemble a telephone handset, with a speaker built into one end and a microphone in the other (in some devices the speaker also is used as the microphone) and an antenna mounted on the top of the unit. They are held up to the face to talk. A walkie-talkie is a half-duplex communication device.
Can cell phones work as walkie talkies?
Fortunately, there are apps that allow you to use your cell phone as a walkie-talkie or two-way radio, some while on Wi-Fi and others so long as you have a network connection—even if it’s just 3G.
Is walkie-talkie illegal in India?
It must be noted that it is legal to use both licensed and unlicensed walkie-talkies in India. No Government permission is required for using them.
Who uses walkie?

How many channels can a walkie talkie communicate on a cell phone?
A typical cell phone can communicate on 1,664 channels or more! Range – A walkie-talkie can transmit about 1 mile (1.6 km) using a 0.25-watt transmitter.
How sophisticated is a cell phone compared to a radio?
A good way to understand the sophistication of a cell phone is to compare it to a CB radio or a walkie-talkie. Simplex vs. duplex – Both walkie-talkies and CB radios are simplex devices. That is, two people communicating on a CB radio use the same frequency , so only one person can talk at a time. A cell phone is a duplex device.
What is the signal strength of a cell phone radio?
Many cell phones have two signal strengths: 0.6 watts and 3 watts (for comparison, most CB radios transmit at 4 watts). The base station is also transmitting at low power. Low-power transmitters have two advantages: The transmissions of a base station and the phones within its cell do not make it very far outside that cell.
Can cell phones and base stations reuse the same frequencies?
Because cell phones and base stations use low-power transmitters, the same frequencies can be reused in non-adjacent cells. The two purple cells can reuse the same frequencies. Each cell has a base station that consists of a tower and a small building containing the radio equipment (more on base stations later).
