Two-Way Radios are radios that can transmit and receive both radio waves. Unlike a conventional broadcast receiver, it is an all-in-one unit, a transceiver and transmitter in a single unit, utilized for walkie-talkie-like communication with other wireless users using the same radio. The primary use for a two-way radio or walkie-talkie is for personal communication, but it has also been used as a security device for military units, boats, and airports. It can be used to send and receive data, or be used as a tracking device. It is usually portable, making it ideal for use in a variety of applications.
Two-Way radios offer many advantages over other forms of communications. These radios can work in any direction, from indoors to outdoors. They can communicate with other users, even when the user is not within a signal range of the other person, or device. This type of networking allows users to work together even if they are geographically apart, or if one user is unable to reach another wireless user on foot. In addition, by using multiple channels, two-way radios can communicate at much greater speeds than other forms of networking.
Two-Way radios are commonly used by schools and government agencies for communication and data-gathering purposes. Schools can use these radios to alert students of a school-wide bus accident for example, and for emergency announcements, and to inform other teachers on field trips. In businesses, two-way radios are frequently used for communication between different departments or units within a company. Government agencies often use two-way radios for communication, and data-gathering purposes.
Two-Way radios are available with several options to choose from. The most popular types of two-way radios are unlicensed radio frequency (also called i.e. W2W) and licensed radio frequency systems. Unlicensed two-way radios generally are more affordable and are easy to operate. However, they lack the licensing requirements that are required for licensed systems. Some individuals may choose to purchase both types of systems, in order to communicate with various people and devices, even without interfering with each other.
Two-Way Walkie Talkie Systems
Two-Way walkie talkies are handheld devices that allow users to communicate over a limited distance. Although some two-way radios have a larger capacity than others, all two-way walkie talkies are able to transmit radio signals over a 200-feet range. This distance is enough to allow individuals to communicate inside a building, or to communicate with other individuals on the move.
Two-Way Walkie Talkies operates on the 2.4 GHz frequency bands. They are able to communicate using a short-wave radio transmitter in a range of 200 feet. Some two-way radios operate in a higher mega-wattage output, while others operate at lower frequencies. Regardless of the frequency used, all two-way radios are capable of providing clear, strong communications.
