Mobile technology has greatly improved over the past years. However, cell phones have some inadequacy at some point. They are reliably dependent on network coverage and tend to fail in areas with poor or limited coverage. On the other hand, walkie talkies beat them to this. Do all walkie talkies work together? This is a question being asked by many users or those planning to acquire such devices. To answer this question, one will have to understand how the device works. You have to know the basics involved in operating the device. They are wireless radios that can be easily carried around. One has to understand the technology and the modalities associated with the workings of the walkie talkies. This is the best way to answer the question.
These are battery powered transceivers (it can send and receive a radio message). They operate on half-duplex channels. This implies that one device, on a single channel can transmit one signal at a time though many devices will be able to receive that signal. The radios are primarily designed for short-range communication and transmit signals directly to each other.
All walkie talkies have similar basic components that include a microphone, speaker, antenna, battery and the PTT button. All these features combine to make communication successful. These devices are designed to operate on particular radio frequencies. The United States has designated different frequencies to meet users’ needs. The public are allowed to use the Family Radio Service (FRS) and the General Mobile Radio Service (GMRS). The GMRS or FRS radios operate on the 460MHz range. The government has also set a side frequencies (the Business Band) that corporates can use (it ranges from 450 to 470MHz). Law enforcing agencies such as the police also have their own frequency so that there is no interference from public users. This is helps the agency to prevent their channels from overlapping with those of public users.
As already discussed above, the GMRS and FRS, frequencies are designated for public use. These channels overlap at particular frequencies even though radios that use such channels have several distinct differences.
The FRS radios have a fixed antenna. They are not quite powerful as their power is limited to about 0.5 watts. These features make their use limited to a small area. They are better suited to personal use as they only operate on the FRS bands.
The GMRS radios are more powerful and have a power of about 5 watts. They can also use repeaters to enhance their radio signals and thus boost their range.
There are many hybrid radios now that can be able to operate on both channels. However, only licensed operators are allowed to use the GMRS channel. This is because the GMRS walkie talkies are powerful enough to cause more interference.
Europe has restricted walkie talkies to PMR446 frequencies or those at just around 440MHz. It is illegal to use a radio operating on the PMR466 frequency on the GMRS or FRS channel. Therefore, if you are travelling from Europe to America, it is very important to make sure that your radio operates on the required frequency to avoid getting in trouble with the law.
From the discussion above, it is clear to see that their operation is restricted only by the frequency of the signal and not the brand. When one uses walkie talkies of the same brand, they are least likely to experience problems in signal transmission and reception as they are more similar in operation. However, this does not mean those using different brands will not communicate.
These radios are all about sending and receiving signals. Therefore, signals sent from one radio at a certain frequency can be received by another radio in that range.
What makes these gadgets stand out from cell phones is their simplicity. One does not need to dial any number to call, all you need to do is to push the PTT button when either reaching out to transmit or receiving a transmission. This applies regardless of the brand one has as they all have similar features as discussed earlier.
In conclusion, in more than one word, the evidence suggests that type of brand does not matter. Therefore, do all walkie talkies work together? Yes, they do.
