Friends chances are very high that you should be Reading this post in your brand new, shining 4G, Super G, High G, Five G smart phone and thinking that walkie talkie in 2017 that "khar khar" sound producing radio why do we need this Friends, we need this because the concept is totally different here Mobile phone is Mobile phone and Walkie talkie is Walkie Talkie Your phone is not more than a paper weight without network But walkie talkie creates its own network and you can talk to your team very easily and freely.

 How Walkie Talkies Works

What happens is, the concept of walkie talkie is not a today's talk we are using it since the era of World War II When military people used to carry radio units on their back including a big battery and a long antenna and walking with it so that whole military can communicate and now a days you may have seen many cops which is a common example and they have a small unit so that they can share some messages and talk So what is the complete concept of that?

So concept is, here you've got similar component in Walkie-Talkie like first isTrans reciever means a Transmitter and a signal reciever and a loudspeaker, battery some circuitery, microphone and a Push to Talk Button So, friends, lets assume you have 10 members in your team and 10 members are distributed in a smalll area Some one's here, someone's there and someone's 500mts away and You want to talk to all at once so everyone has their walkie talkie units and decided a common channel means a common frequency on which all will talk lets assume 465mhz and everyone staioned at that unit and assume if a person wants to talk to whole team so he will press the push to talk button and walkie talkie will accquire listening mode and said message will reach whole team and after that someone from team can reply that message that will everyone so basically,

in your small are you are creating your own signals using that walkie talkie and easily talking to everyone here concept of range depends on strength of antenna and toy walkie talkies that you get will work in 100,50, 200 ft but here if I talk about Police walkie talkies commercial heavy units for that you being an individual or a business owner will need a license in most cases so in these case the ranges can go upto many kilometers and it depends on efficiency and power of unit so this was a common example another example is if you want to talk to each and every person in your team so lets assume shooting of a film where there is sound man, light man, a directora choreographer and all are standing there following their duties and you need to call a person for some work or to ask some thing so what they did, all 10-12created a separate personal channel sand you all have list that which person is using which channel and if I want to talk to a specific personal I will tune his channel on my radio and my said message will reach to only that person and we cal talk easily and remember you need to say ''over'' when your sentence ends in order to notify that you finished your sentence and you will receive reply after completing of conversation you need to say over and out that are simple radio manner share, besides this concept changes in military because, in military and police you don't want your message to be listened by someone outsider so here, encryption is used sometimes, frequencies also change in a particular manner or sometimes data is simply encrypted so that it can be decrypted using a key so it is not true that in way I placed my own antenna and can listen police conversations besides that, you should have seen its uses police spreaded out in whole city and using a common channel so that to catch a criminal so everyone can contribute its update instantly can transfer messages so this is very useful device in factories, big business you can use it in different places like when hiking or you want to find anaconda in amazon and in different scenarios, walkie talkie is definitely better than mobile phones you get a good battery life yes mobile phones also provide same functionality using some apps but a traditional standalone walkie talkie unit cannot be replaced by mobile phones because both have dedicated different work share you can download in 4Gapps + games and walkie talkie is meant for only communication(p2p or broadcast)where sometimes loudspeakers and mic becomes a single unit for the purpose of cost cutting both the modules are fixed in one unit and working as loudspeakers as well as mic depending you have pressed push to talk button and in some cases these are analog and in some cases these are digital means walkie talkie is own personal radio just press the button and connected people will listen your voice and sometimes your neighbour could be using same channel while playing with kids and your walkie talkie is one same channel so you can also listen to same message you should different channels in order to reduce interference and you can personalise your communication using different frequencies range
