Naval air traffic controller communicates with aircraft over a two-way radio headset A variety of portable handheld two-way radios for private use. A two-way radio is a radio transceiver (a radio that can both transmit and receive radio waves), which is used for bidirectional person-to-person voice communication with other users with similar radios, [1] in contrast to a broadcast receiver ...
The basic NXDN channel is digital and can be either 12.5 kHz or 6.25 kHz wide. 6.25 kHz dual-channel systems can be configured to fit within a 12.5 kHz channel. This effectively doubles the spectrum efficiency compared to an analog FM system occupying a 12.5 kHz channel. The architecture of NXDN is such that two NXDN channels, within a 12.5 kHz ...
The ARC-210 program began in 1990 as an improved version of the AN/ARC-182, adding jam-reisistant SINCGARS capability to communicate with Army radios for close air support. [2] The Arc-210 is installed on more than 180 platforms and is operating in more than 40 countries. As of 2010, 30,000 have been produced [3] and by October 2016, 40,000 ...
A trunked radio system is a two-way radio system that uses a control channel to automatically assign frequency channels to groups of user radios. In a traditional half-duplex land mobile radio system a group of users (a talkgroup ) with mobile and portable two-way radios communicate over a single shared radio channel, with one user at a time ...
The AN/PRC-148 Multiband Inter/Intra Team Radio (MBITR) is the most widely fielded handheld multiband, tactical software-defined radio, used by NATO forces around the world. [ 1 ] [ 2 ] The radio is built by Thales Communications , a subsidiary of the France-based Thales Group . [ 3 ]
In a conventional, analog two-way radio system, a standard radio has noise squelch or carrier squelch, which allows a radio to receive all transmissions. Selective calling is used to address a subset of all two-way radios on a single radio frequency channel. Where more than one user is on the same channel (co-channel users), selective calling ...
The USMC ordered 60,000 radios to be used until replaced by the more complex Joint Tactical Radio System (JTRS) cluster 5 spiral 2 radio in 2013. [2] However, JTRS was cancelled in October 2011, [3] and thus the PRC-153 continues to serve. The IISR is a Motorola XTS 2500i [4] with embedded encryption module to provide secure voice communications.
