The independent wireless networks

By Milica D. Djekic

The wireless technologies would actively attract the researcher’s attention during the last few
decades. The era of wireless information transfer has begun around two centuries ago with the
discovery of electromagnetic waves and field.

What changed since then? Well, today’s wireless systems would be much more sophisticated,
but they would still rely on electromagnetic phenomena. So, if you want to design any wireless
system – you would need to deal with the electromagnetic waves possibly being sent using
some frequency channel and desirably some encryption protocol which would protect them from
the external monitoring.

Through this article, we would talk about how it’s possible to design the independent wireless
networks and how such a sort of technology could be used for defense purposes.

The idea of independent wireless networks is quite new and right here, we would use it to
explain how such a sort of endeavor could be used for both – defense and industry purposes.

For instance, it’s possible to use an electromagnetic wave transmitter being charged using
power supply relying on the electricity network or – for terrain applications – some battery
equipment being capable to get re-charged from some electrical source.

The electromagnetic transmitter would generate the electromagnetic waves and send them
through some frequency channels.

Also, it’s pretty important to protect such a system from the outer surveillance and for such a
purpose – it’s recommended to use some sort of cryptographic security.

This article would deal with all of those topics quite briefly leaving more space to a discussion
regarding the applications of such a project.

It’s well-known that a transmitting power of some wireless device would mostly depend on its
electrical power, so if the battery or charging system can produce more power – the better the
range of such a device would be.

In other words, if you got a good transmitting power of your wireless device – more far away its
signal would go.
