Radio

Radio technology – traditionally understood as the wireless broadcasting of audio signals like music and speech – has had a fresh lease of life in recent years.

In simple terms, radio technology leverages the electromagnetic radiations (EMR), which can be oscillate at desired frequency and allow trans-reception of data when attuned to the correct value. EMR waves travel at the speed of light, through any media (or even vacuum!), and may be used for either near-field or far-field communication based on the frequency specifications. In short, radio waves are just low-frequency versions of what we call “light”. Range of these EMR wave frequencies comprise a particular ‘channel’, which is precisely what the radio stations adhere to.

Commercially, the need for transmitting information over geographical distances has skyrocketed in recent years, as has the demand for radio to meet those needs. From radar, sonar, GPS navigation systems, wireless networking, and cellular data plans at industrial scale to Bluetooth technology and near-field communication (NFC) for your hand-held devices, radio is omnipresent.
