Two-Way Radios

The two-way radio is actually a radio that may both receive and transfer (the transceivers). Many times, most of these voice wireless communication systems, including cellular systems, fall into two-way radio types.


The Two-way radio is a radio system mainly utilized for team interaction and is also called as:

  • Professional Mobile Radios (PMR)
  • Land Mobile Radios (LMR)
  • Private Mobile Radios (PMR)
  • General Public Accessibility Mobile Phone Radio (PAMR)


Number of these contemporary two-way radio handsets are compatible with the Project 25 digital radios. The two-way radio is the system that can receive and transfer, unlike transmit receiver, that only receives the content. The two-way radio enables the operator to receive and transmit impulses from other similar radios stations with similar radio frequency. Two-way radios are accessible in mobile phones, Portable mobile handsets as well as the base stations. These Hand set radios are known as walkie-talkies, handy-talkies or even hand-held devices.


Two-way radio system usually runs in half-duplex mode; which means, the owner can either talk or listen at any given time. A Push To Transmit or push-to-talk button triggers transmitter; when it gets launched the recipient becomes active. Full duplex can be achieved by using 2 different frequencies or by using frequency-sharing techniques to transmit two instructions of  conversation at the same time. Techniques for mitigating self-disturbance caused by simultaneously transmitting and receiving same-frequency consist of using two antennas, or strong state filter system. A radio repeater can also help two-way radios be used farther apart.


Why you must use Two-Way Radio?


With numerous wireless technology choices available today and two-way radio becoming one of the “earliest” wireless systems, you may be wondering whether two-way radio is the current technology. The answer is yes and the following are the important factors that uniquely differentiate two-way radio with other wireless technology:


Instant interaction

Two-way radio provides instant interaction. An individual only needs to push the “Push-To-Talk” (PTT) switch and in a fraction of second, he or she can immediately speak to convey his or her information.


Team communication

One more distinct feature of two-way radio is its capability to facilitate “one-to-many” team interaction (also referred to as “group call”). Here one consumer can speak to a group consisting of large number of users simultaneously. The user does not have to replicate the same information over and over again if he or she needs to convey to more than 1 user.


Who are the Two-Way Radio Customers?


Two-way radios are being utilized since many years by numerous industries and organizations. Due to the nature of their requirements, they need to utilize radios to address their communication requirements. Types of companies and sectors that rely on two-way radios are:

  • Public Security organization: Fire, Law enforcement, Emergency Healthcare Services / Ambulance Service, Disaster Recuperation Company
  • Safety: Intelligent agencies and Military
  • Transportation: Train, Light Rails, Airport, Seaport, and Subway
