Owning Walkie Talkies Is Advantageous Where Cell Phones Don’t Work

Two way radios are also called walkie talkies. Many variants of the two way radios are available today. One can choose a simple one that children use or a highly sophisticated model that is commercially viable. When you are out shopping for walkie talkies, the few points to consider would be:Model: TC780

  • The reason of purchase
  • The number of frequencies available on the set
  • The private coding available in the set
  • The battery life of the set
  • How the cells would be recharged
  • The distance covered by the walkie talkies

If the walkie talkie is to be used by children going on camps, then the point to consider would be the surroundings. The radio should be able to work in such conditions. On the other hand, if distance is to be considered, then the walkie talkies should be one that would cover a long distance.

In case, your consideration is clarity, then the choice of a two way radio would be one with more bands. Considering all the aspects before purchasing would help to use the walkie talkies with ease.

Companies like Hytera have launched highly sophisticated walkie talkies that receive the signals from repeaters easily.The signals received are improved and relayed through a different frequency by a spreader. This, in turn helps a two way radio perform better.

Though, cell phones are very useful and handy; there are situations, where having a walkie talkie would be advantageous. Since, a two way radio works on short radio frequencies, it works at places where a cell phone sends out of coverage signals.

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.

These DMR and PMR radio systems are Trunking Systems, which indubitably plays a major role in the construction sites. However, in the construction sites, the employees often need to communicate with each other to successfully and safely perform the job works or any construction works despite the noisy environment. The Two Way Walkie Talkie is worthy to use in such an environment. It offers crystal clear audio quality by using the Narrowband Codecs technology and thus one can able to hear the clear voice and can safely perform the job works.

RepeatersThe intermittent slowdowns of network are to be expected in many corporate offices or residential areas. There is a plethora of obstacles that can weaken the signal strength and thus cause a network problem. One of the reasons of such a cause is the increasing network traffic. Such a problem can be averted by using Trunking Systems. The Trunking radio system also uses wireless repeaters that come with many towers, and multiple frequencies, which ensures the signal strength and also allows to have conversations between many groups of users.

Thus, the Digital Two Ways Radios including the Covert Radio and Licence Free Radio (aka private radio) have been proved to be useful in various ways to the people working in all sectors including government or private, commercial or non- commercial.

Walkie Talkies – A Compaq and Easiest Means of Sharing Messages

Walkie Talkie

Walkie talkies are the handheld tools popularly known as two way radios also. This system functions on the principle of half duplex, wherein messages can be sent and received one at a time. Users have to press the button present in walkie talkie to send the message and have to release it to receive the message. Their functionality is not bound to any time duration or size duration. Users can send longer messages also. Walkie talkies are mostly used in malls, defence offices, commercials and also for personal use in large distances.


If we recall the old days, our parents use to make trunk calls. You must have wondered ample of times thinking about the meaning. Trunk calls follow Trunking systems wherein from single frequency, multiple connections can operate. This enables easy and secured sharing of information within the organization. Though there are many modes of communications available in the world due to technological development, the base for these modes remains the signals of the network. There is a huge indoor and outdoor coverage problem in rural or congested areas. Repeaters amplify the existing signals from the nearby base transceiver system and provide fair coverage and voice quality.

Continuous growth have evolved the production of DMR Radio (Digital mobile radio) providing services of optimum privacy to the confidential conversations and also providing good coverage and voice quality. Terrestrial trunked radio (Tetra) is yet another radio derived from ETSI. It works on two RF’s (radio frequency) and used mainly by government projects, hospitals and commercial offices.

The Trunking Systems and the Working of Other Radio Systems for Security and Entertainment

In the past when the mobile phones were not available and it was not within everybody’s means to have landlines with the STD and ISD connections. The Telephone Exchange used to offer the use of trunk calls, to where ever you needed. This was possible with help of the Trunking systems.

The idea of trunking, in which a main telephone switch board with many connections that use a same sound wave length can use instead of each one being allotted a different personal link. A miniature form of the trunking system can be seen in offices where a telephone operator and intercom systems are used.

With the use of the two way radio handset, called walkie talkie, nobody can complain about the communication amongst the working team or other group members. But, yes, one has to watch the area coverage by the walkie talkies. The walkie talkies were originally designed for the exclusive use of the police and security force. Later on the commercial models of the same were sold in the market for the use in many professional fields like construction.

The PMR radios were replaced with an advanced version called DMR radio or the digital mobile radios. The DMR offers talking, information and various other facilities and aspects. The chief motto of the DMR is to offer an easy to handle, minimum price factor and inter usable feature with all the other brands.

Instead of using many radio sets and other connecters to improve the reception range of the service repeaters are used at intervals to increase the area of reception of conversations, information and other features. Tetra or the terrestrial trunked radio is movable radio working on two frequencies. Tetra was patterned mainly for the use of various departments of the governing bodies and other SOS services.

Development of Digital Two Way Radios

Information and Technology has developed rapidly within last decade and now in 21st century the means of communication has reached a level where there is no barrier to it. Now people are free to use individual network lining and can avoid any bad audio quality or fading problems. There are trunking systems that allow better radio frequencies without any line breakage or fading. These systems are comparatively cheaper to older individual lining system.

The digital radio broadcasting technologies now has developed better systems and networks for digital two way radios giving the DMR radio better options to connect and work. These are 2nd generation radio systems and as they are two way, you can both transmit and receive message. These radio systems are most useful for security agencies for individual and mass protection. Police, fireman, military and such security agencies use these types of radio mobile systems.

These systems can be of different types, depending upon their use they can be mobile, stationary base, and walkie-talkies. To work these types of radio the networking system needs different levels of support and backup. Such supports should be provided without any interruption and for this a direct satellite network connection is also maintained specially in the case of military and high level security systems. In mountain areas the network gets blocked by different blocks and frequency mix and to solve this problem repeaters are used. A repeater takes the message and retransmits it to higher level so that the message goes without any interruption to long distance.

Digital Mobile Radio (DMR) is an upgraded open digital radio system for Professional Mobile Radio (PMR) and to support them the ETSI (European Telecommunications Standard Institute) made Terrestrial Trunked Radio (TETRA) system. It is a two way receiver and is best for mass security purpose, because with this system one can transfer and receive message from point to point and from point to multipoint and vice-versa. These radios can also be operated hands-free and so can be referred as covert radio.

A digital licence free radio is latest addition to two way radio system that gives you charge-free communication facility. This system is used for private use and they work with the help of repeaters and internet. The only drawback of this radio system is that they work only within few kilometres range that too if the area is clear and viable for PMR and DMR frequencies.
