Connecting Through The Trunking Systems

The working of a Trunking Systems for people who are not aware of the term can be said to functioning the same way as a trunk of a tree that connects all the different branches of a tree to the roots of the tree. It acts as a medium or a bridge between the two. The same way this system works by connecting different tetra radio with a common base station. The science was not invented for the radio industry but has been taken from the telephone technology where trunking was used for STD connections.

Trunking systems helps in:

  • Minimizing the total number of lines required otherwise for any project related to one to many or many to many connections.
  • The infrastructure and the raw material required for the same also gets reduced drastically.
  • The total number of lines that would have remained idle otherwise will be reduced as trunking system itself finds an empty line for transmission and receiving of messages which otherwise would require one line each for receiving and transmitting messages. Multiply these with the total number of users that would be transmitting and receiving messages at a time and you would know that the lines required for such connections can go as high as a million.
  • The trunking systems reduces the hassle of maintaining so many lines and provides a hassle-free solution for establishing the same number of connections with a minimum number of lines.
  • The system is a boon for services related to defense and emergency as minimum number of lines to handle makes it easier and swifter to transfer messages.

Communicate With The Help of Walkie Talkies

Walkie Talkies are simple instrument that can be used to transfer messages from one point to another through a fixed radio frequency that is being used by just that instrument. This turns out to be a safer and a faster way for communication and yet is not used as much as it should be used. The reason here can be the unawareness of people related to the use of the DMR radio and other such frequency using instruments. Although these instruments cannot be used as a substitute for any other modes of communication but still they can very well prove to be useful in branches where other modes of communication may not function to well say for e.g. construction sites. For huge construction sites, these can prove to be of great help in connecting and transferring messages from one part of a site to another part.

DMR radio have been introduced to the market as a low cost option to other radio frequencies users who wish to make use of the land mobile frequencies as a mode of communication and yet be safe from issues related to proprietary. Walkie Talkies also functions in the same manner but within a fixed frequency band and can solve problems of communication in areas where the perimeter of work is limited to a fixed small area. As each and every thing that is present in this world, these instruments also have their positives and negatives but if thought and developed properly, these modes of communication can prove to be cheap as well as time saving.
