Using a Two Way Radio

All of us wish to connect with our loved ones on mobile or the internet or through wired telephones but these types of communications are altogether different than what is required in the field. Modern ways of communication cannot be used in all fields of work as there is a chance of breach of safety and security while transmission and receiving of signals through packets. Hence a safer and an easier mode of communication is the two way radio. A 2 way radio works two ways on the same frequency. A simple walkie-talkie or such instrument is used to establish a connection between two persons or between a radio station and a worker. The radio sends a signal through one frequency and again receives it back on the same frequency.

2 Way Radio

Once you are sending a message on a two way radio, you cannot receive a message on the same radio as it uses the same frequency to do both the tasks. Hence, in a 2 way radio you either send or receive a message.

• The first step you do is pushing a button and saying your message, the radio transmits your message in the form of packets and the receiver receives it on their instrument.

• Next, the receiver pushes the button of his instrument and says his message and you receive the message on your instrument.

The radio works the following way and helps in receiving and sending messages faster and easier than any other mode of communication and in places where other communications can prove to be costly.

Communicating Below the Sea with Marine Radios

Radios are a very common instrument for each and every one of us around. Different types of radios are known to us such as the old AM radios, the new FM radios but all these are only radios that can receive radio signals either in AM mode or FM mode. A rather deeper and a more serious use of radios are made in emergency services such as the police departments, fire fighters, ambulances, armies etc. All of these use radios and these radios work best on land. Another use of radio made in the defence is by the navy.

 As the navy has to do all its work in or around water, a special radio called Marine radio is used for communication.

This Marine radio makes use of the wireless radio technology for receiving and transferring signals over and below the sea. Since defence is a very important and a secret part of any country, special frequencies are used for receiving and transmitting the messages. Wireless radio transmits the radio frequency through a medium, either air or water, and hence is highly susceptible to signal losses and noises at the receiver end.

Hence, special high frequency waves are used that can penetrate deep into the ocean and avoid signal losses and attenuation. Also since these waves travel through a medium, safety is often a concern and so even after taking all of the care to avoid such unwanted copying of signals, as a safety measure, the messages are sent as codes that need to be deciphered at the receiver end.

2 Way Radio and Its Variants have a Place in Every Household

The need of communication is increasing in day to day life for any sector bee it medical, paramedical, defense, politics, education and all. So in this era very useful device named digital mobile radio arose.

                                      

It is based on a two slot technology known as TDMA (Time Division Multiple Access). This tool divides the channel to increase the data and voice transfer both. Digital Mobile radio is efficient in terms of Low cost, flexibility, complexity, compatibility, reliability. Many such products are made and catered by a company named Hytera. Hytera.in offers many different models of Digital Mobile Radio while complying with all the ETSI specifications. Furthermore, this kind of product is produced by many suppliers all over the world also complying with ETSI specifications, thereby increasing the supplier’s variety.

The advantages which DMR offers are enhancing the capability to two in the presented channels with the help of time division multiple access technology. It has sustainable battery life with higher power. Also it shows increased voice clarity, quality and data presentation. Further the frequency gets widened when it is compared to analogue signals thus removing the existing limitations.

DMR is a best choice for professionals. It can use data and voice both through the help of two slots provided in the time access multiple division technology thus providing extra benefit in compare to the existing frequency division multiple access which can only go through one channel at a time. Hytera offers six different models for DMR.

There is an association fully dedicated to DMR namely Digital Mobile Radio Association. Digital Mobile Radio Association is the firm which is centered to widen the awareness of the professionals who buy the product. Professionals like producers, users and application developers can become a member. The Purpose is to broaden the variety of Digital mobile radios and processes for certification. 

For the products like Digital Mobile Radio many factors are considered like energy consumption, legal requirements, system potentiality, spectrum and licensing. Digital Mobile Radio outperforms all the above mentioned factors and that’s why it’s a professionals’ choice.
