In the United States, the expansion of work from home has frequently occurs in which communication speed is delayed or emergency calls are not connected.Under such circumstances, FIRSTNET is a communication network for fast -less ponders such as police and firefighters.Since 2021, the FBI has been used, and it has been established as a service with fast communication speed and highly confidential service.What kind of communication network?
FirstNetは、主に治安や人命救助に関わるファーストレスポンダーのために設計されたネットワークシステムです。緊急時におけるファーストレスポンダーの通信ネットワークを最速化かつ最適化するために、米国商務省内の独立機関であるFirst Responder Network Authority と大手通信会社のAT&Tが、全米規模の通信ネットワークとして2017年から整備を始めました。
Communication of police and rescue workers often requires urgency, but if you are hit by natural disasters or terrorism attacks, mobile phones will quickly become excessive access, and for first -less ponder actions and judgments.It has an adverse effect.In addition, as a result of the spread of remote work due to corona evil, the communication speed delay and trouble increased.Under these circumstances, the construction of a communication system for fast less ponders was required.
One of the features of the firstnet is that the main frequency is 700MHz band.In 2012, the US Congress passed the Spectral Law, but this law aims to secure and use 20MHz, which is said to be particularly good among the 700MHz frequency band called "band 14", for emergency communications.increase.The biggest advantage of 700MHz is that by using low -band radio waves that can pass through walls, you can communicate anywhere, regardless of location or obstacles.Radio disorders are minimized, and smooth communication is possible in a closed environment even in the event of a disaster.At present, Firstnet is said to be better than any other next -generation high -speed communication line around the world as the only communication service that meets the standards of band 14.
Another feature of FIRSTNET is "Z-AXIS".This is a function that allows you to see the 3D position information of the "vertical axis" in addition to the conventional two -dimensional GPS position information.For example, if a person seeking help in a building fire or the like had 911, the conventional GPS function tracked the caller with only two -dimensional map information.However, with Z-AXIS, three-dimensional location information allows you to grasp how the caller is on the floor of the building, in addition to the location of the building.It will also reduce the risk of secondary disasters in First Less Ponders.As of October 2021, Z-AXIS is available in more than 105 cities in the United States, including Chicago, Dalla, Detroit, Los Angeles, Philadelphia, and San Francisco.
FIRSTNET equipped with Z-AXIS has introduced more than 17,000 organizations, including federal governments, state governments, and local governments, but because of its high service speed and high confidentiality, FBI in December 2020.The US Federal Investigation Bureau has signed a total of $ 92 million (approximately 10.4 billion yen *) in five years with FIRSTNET and has been used since 2021.
* 1 dollar = about 113 yen (as of November 8, 2021)
In addition, the U.S. Air Force has decided to use the service from October 2021 for the next 21 years at 15 bases.As a result, the Air Force Base will carry out audio, data, streaming video communication, and existing radio equipment, and communication between fast less ponders and local public safety agencies in the base is safer.And you will be able to do it at high speed.
Establishing a dedicated network that can respond agilely in the event of a fast -less ponder is essential for modern society where remote work has become popular.In Japan, networks like FirstNet are being discussed, and it may be more important in future communication infrastructure.
