Icom, to meet the new standard start released the 260MHz band municipal disaster prevention administrative radio system.
Icom Co., Ltd. (Headquarters: Osaka-shi Hirano Ward, president and CEO: Tsutomu Fukui) will start manufacturing and selling 260 MHz band municipal disaster prevention administrative radio system conforming to the new standards from late January 2017. For an overview of the system, please refer to the attached document.
<Municipal disaster prevention administrative radio system and is>
municipalities, in addition to collecting the disaster prevention information that becomes the key to protect the safety and security of local residents, it will be asked to convey accurate information quickly in the event of a disaster.
The infrastructure supporting the communication is the municipal disaster prevention administrative radio system. From the viewpoint of efficient use of radio waves, transition from analog to digital is promoted by some countries.
<To meet the new standard, excellent system for voice communications>
system to be released this time is, 2015 December 3, the development has been ARIB standard ※ 1 intended to be consistent with the (STD-T116), 260MHz band This is a mobile wireless communication system adopting the modulation method called 4-value FSK method that uses radio waves.
Compared with the conventional π / 4 shift QPSK system, which is a 4-value FSK system, the circuit configuration of the device is not required to be complicated, so it is necessary to maintain a voice communication based system relatively inexpensively It is a feature that is possible.
<Smooth full lineup of equipment required for the operation>
radio terminal is, of course, base station radio equipment, control boards, such as the command console, a lineup of essential equipment to smooth system operation, strong in information transmission of voice communication center It is a configuration. In addition, the portable radio terminal that case be forced to operations in a harsh environment is assumed, the highest level of waterproof (IP67 / 66/65 ※ 2 ) is, of course, the United States military procurement standards (MIL- STD – 810G) Weather resistance and robustness are also secured.
- 260 MHz band municipal digital mobile communication system conforming to the ARIB standard (STD – T 116).
- It adopts 4-value FSK method, and can be developed at a relatively low cost compared with the conventional method.
- Base station radio equipment, control board, command desk, etc. Lineup of transceivers essential to the system.
- Radio terminal is the highest level of dust-proof and waterproof (IP67 / 66/65) ※ 2 In addition to having the, ensure the weather resistance and robustness to meet the US military procurement standards (MIL-STD-810G).
