Icom Inc. (アイコム株式会社, Aikomu Kabushiki-gaisha) is a Japanese manufacturer of radio transmitting and receiving equipment, founded in 1954 by Tokuzo Inoue with the company's original name being "Inoue". Its products now include equipment for radio amateurs, pilots, maritime applications, land mobile professional applications and radio scanner enthusiasts.
Its headquarters are in Osaka, Japan,with branch offices in the United States (in Kirkland, Washington), Canada (in Delta, British Columbia), Australia (Melbourne, Victoria), New Zealand (Auckland), the United Kingdom (Kent, England), France (Toulouse), Germany (Bad Soden), Spain (Barcelona) and the People's Republic of China (Beijing).
IDAS is Icom's implementation of the NXDN protocolfor two-way digital radio products intended for commercial Private Land Mobile Radio (PLMR) and low-end public safety communications systems. NXDN is a Common Air Interface (CAI) technical standard for mobile communications. It was developed jointly by Icom and Kenwood Corporation.
The D-STAR open radio system was developed by Icom based on digital radio protocols developed by the Japan Amateur Radio League and funded by the Ministry of Posts and Telecommunications.This system is designed to provide advanced voice and data communications over amateur radio using open standards.
Icom manufactures two way radios and receivers for use in marine applications, Airband, amateur radio applications, land mobile applications,and FRS / GMRS applications. Some radios made by ICOM are compatible with Motorola and SmarTrunk trunking systems.
Packet radio is a digital radio communications mode used to send packets of data. Packet radio uses packet switching to transmit datagrams. This is very similar to how packets of data are transferred between nodes on the Internet. Packet radio can be used to transmit data long distances.
A walkie-talkie, more formally known as a handheld transceiver (HT), is a hand-held, portable, two-way radio transceiver. Its development during the Second World War has been variously credited to Donald Hings, radio engineer Alfred J. Gross, Henryk Magnuski and engineering teams at Motorola. First used for infantry, similar designs were created for field artillery and tank units, and after the war, walkie-talkies spread to public safety and eventually commercial and jobsite work.
A two-way radio is a radio that can both transmit and receive radio waves, unlike a broadcast receiver which only receives content. It is an audio (sound) transceiver, a transmitter and receiver in one unit, used for bidirectional person-to-person voice communication with other users with similar radios. Two-way radios are available in stationary, mobile, and hand-held portable models. Hand-held two-way radios are often called walkie-talkies, handie-talkies or hand-helds. Two-way radios are used by groups of geographically separated people who need to keep in continuous voice communication, such as aircraft pilots and air traffic controllers, ship captains and harbormasters, emergency services personnel like firemen, policemen, and ambulance paramedics, taxi and delivery services, soldiers and military units, fast food and warehouse employees, and radio amateurs.
Project 25 is a suite of standards for interoperable digital two-way radio products. P25 was developed by public safety professionals in North America and has gained acceptance for public safety, security, public service, and commercial applications worldwide. P25 radios are a direct replacement for analog UHF radios, but add the ability to transfer data as well as voice, allowing for more natural implementations of encryption and text messaging. P25 radios are commonly implemented by dispatch organizations, such as police, fire, ambulance and emergency rescue service, using vehicle-mounted radios combined with handheld walkie-talkie use.
Digital Angel, Corp. is a developer and publisher of consumer applications and mobile games designed for tablets, smartphones and other mobile devices, as well as a distributor of two-way communications equipment in the U.K.
Kenwood Corporation was a Japanese company that designed, developed and marketed a range of car audio, hi-fi home and personal audio, professional two-way radio communications equipment, and amateur radio ("ham") equipment. Since October 2011, Kenwood survives as the brand of JVCKenwood Corporation.
The Enhanced Digital Access Communication System (EDACS) is a radio communications protocol and product family invented in the General Electric Corporation in the mid 1980s.
A trunked radio system is a digital two-way radio system that uses a digital control channel to automatically assign frequency channels to groups of users. In a traditional half-duplex land mobile radio system a group of users with portable two-way radios communicate over a single shared radio channel, with one user at a time talking. These systems typically have access to multiple channels, up to 40 - 60, so multiple groups in the same area can communicate. In a conventional (nontrunked) system, channel selection is done manually; before use the group must decide on which channel to use, and manually switch all the radios to that channel. This is an inefficient use of scarce radio channel resources, because the user group must have exclusive use of their channel regardless of how little transmission they are doing. There is also nothing to prevent multiple groups in the same area from choosing the same channel, causing conflicts. A trunked radio system is an advanced alternative in which the channel selection process is done automatically.
Radio over Internet Protocol, or RoIP, is similar to Voice over IP (VoIP), but augments two-way radio communications rather than telephone calls. From the system point of view, it is essentially VoIP with PTT. To the user it can be implemented like any other radio network.
D-STAR is a digital voice and data protocol specification for amateur radio. The system was developed in the late 1990s by the Japan Amateur Radio League and uses minimum-shift keying in its packet-based standard. There are other digital modes that have been adapted for use by amateurs, but D-STAR was the first that was designed specifically for amateur radio.
EF Johnson Technologies, Inc. is a two-way radio manufacturer founded by its namesake, Edgar. F. Johnson, in Waseca, Minnesota, United States in 1923. Today it is a wholly owned subsidiary of JVCKenwood of Yokohama, Japan.
MPT 1327 is an industry standard for trunked radio communications networks.
Multi-Band Excitation (MBE) is a series of proprietary speech coding standards developed by Digital Voice Systems, Inc. (DVSI).
ASTRO 25 is the next generation of ASTRO digital two-way radio communications by Motorola Solutions. Motorola first introduced digital two-way radio in the U.S. in 1991 under the name ASTRO Digital Solutions.
NXDN is an open standard for public land mobile radio systems, that is systems of two way radios (transceivers) for bidirectional person-to-person voice communication. It was developed jointly by Icom Incorporated and Kenwood Corporation. It is an advanced digital system using FSK modulation that supports encrypted transmission and data as well as voice transmission. Like other land mobile systems, NXDN systems use the VHF and UHF frequency bands. It is also used as a niche mode in amateur radio.
Digital mobile radio (DMR) is a limited open digital mobile radio standard defined in the European Telecommunications Standards Institute (ETSI) Standard TS 102 361 parts 1–4 and used in commercial products around the world. DMR, along with P25 phase II and NXDN are the main competitor technologies in achieving 6.25 kHz equivalent bandwidth using the proprietary AMBE+2 vocoder. DMR and P25 II both use two-slot TDMA in a 12.5 kHz channel, while NXDN uses discrete 6.25 kHz channels using frequency division and TETRA uses a four-slot TDMA in a 25 kHz channel.

dPMR or digital private mobile radio, is a common air interface for digital mobile communications. dPMR is an open, non-proprietary standard that was developed by the European Telecommunications Standards Institute (ETSI) and published under the reference ETSI TS 102 658.
PDT is an open industry standard for trunked radio system in China servicing police wireless communications and professional mobile radio. The standard is being maintained by the Professional Digital Trunking System Industry Association, an association of major vendors of wireless communications equipment in China. The association was formed with the help from Information and Communications Bureau of the Ministry of Public Security. The standard was used to facilitate the digital transformation of the Ministry's existing MPT analogue trunking system. Government policy supporting this domestic standard had led to the abolishment of previous GA/T industry standards based on the European TETRA standard.
