CRITICAL COMMUNICATIONS

Static communication infrastructure, such as landlines, mobile phones, LMR networks and fibre infrastructure, are easily disrupted and susceptible to failure through natural and manmade disasters. In some remote areas, this infrastructure simply doesn’t exist.

Organisations providing critical services need a form of communication that works without the need for any external supporting infrastructure. HF radio is an ideal solution, working as either a primary or emergency system for communication.

With an HF radio setup, organisations have everything they need in order to transmit voice, email, fax and data signals over long and short distances - a necessary capability in critical communications scenarios.

Barrett HF radios can provide critical communications capabilities for a number of public- and private-sector applications, including:

Agriculture Construction
Embassies and consulates Energy
Emergency services Fisheries
Forestry Mining
Post Remote healthcare needs
Shipping Telecommunications
Transportation
What is HF radio?

HF radio is a system of communication that operates on the portion of the radio spectrum between 1.6 and 30 megahertz (MHz). This form of propagation uses single side band (SSB) transmissions - an efficient form of voice modulation - to carry signals over both short and long distances.

There are two main forms of radio wave transmission in HF radio: ground and sky waves. Ground waves travel along the Earth's surface, enabling communication across short distances. Sky waves are bounced off the Earth's ionosphere in order to reach transmission ranges of several thousands of kilometres.

With these types of transmission, HF radio facilitates communication to and within isolated areas. A typical setup consists of three components:

  • A transceiver with a microphone, speaker and frequency controls.
  • An antenna for broadcasting and receiving transmissions.
  • An independent power source.
