Why use Long Range Radios?

In the modern world, communication is one of the things that can be done with utmost ease. With the advancements in the areas of internet, cellular and satellite technologies like E-mail, Instant Voice Messaging, Fax etc, communications has become much faster and simpler for general public. Despite these advancements in technologies, organisations are in continuous search of solutions for their remote, secured and urgent communication problems.

The most fitting solution for these organisations would be to use Long Range Radios. They transmit HF SSB (High Frequency – Single Side Band) radio waves which does not require any expensive re-transmission devices. The Long range waves generated by the HF SSB transceiver are of two components.

1. Ground Wave – These waves travel directly from the transmitter to the receiver following the contours of the earth
2. Sky Wave – These waves are the key element for Long range radio transmission. These waves travel upwards at an angle from the transmitter, so that it will hit the Ionosphere and refracted back to the receiver. Please refer the figure below

Long Range Radios have the following advantages which makes them a better option over satellite and cellular communications.

1. Zero Operating Cost – Communications made through HF SSB radios are totally free. On the other hand, Satellite and Cellular communications are expensive
2. Minimal Infrastructure – Long Range Radios are very less dependent on land based infrastructures whereas, cellular and satellite communications heavily depend on infrastructure
3. High Reliability – Due to minimal infrastructure requirements, the Long Range Radios are one of the most reliable mode of communication at the time of a unexpected disaster
4. High Interoperability – Long Range HF SSB Radios can also communicate with short range radios, VHF and UHF radio systems
5. Ease of Deployment – These radios have very less deployment time and can be easily mounted in a vehicle or portable by humans in the field
6. Flexibility – Long Range Radios are highly flexible for E-mail, Instant voice and text messaging and also telephony
7. Highly Secured – Long Range Radios can be used for highly sensitive data and voice transmissions which demands tight security. For example, the armed forces use HF Long Range radios for their communication. There are different encryption and security levels depending on the requirements of an organisation
8. High Control – Long Range Radios is the best solution when there is a need to communicate with multiple users in a group. The military uses this as the default medium in order to effectively monitor commands given to the soldiers, so that they can execute the instructions on time
9. Maintainability – Since there is a minimal need of infrastructure, the Long Range Radios are very easy to maintain
10. Consistency – Long Range radios are consistent in delivering voice and data communications since it completely depends on the sky-wave propagation

Long Range Radios might be one of the most primitive concepts in the communications space. But, it has enormous flexibility to accompany all types of data and voice communications like E-mail, IM etc. Hence, it is the ideal solution for organisations seeking secured, cost-effective and reliable voice and data communications.
