The Electromagnetic Spectrum

[xhm100]

3. Identify the Electromagnetic Spectrum range utilised in modern communication technologies. You must include secondary data in tabular and/or graphical form, interpret it into words and analyse.

What kind of tables or graphs would I want to show here?

look up FCC (Federal Communication Commission).
Some bands are reserved for future expansion, some for emergency,
some for commercial and licenced, some regulated (ham), some public.

How much "reserved" is left for when new technology becomes available?

I would like to provide a response to the content on the Electromagnetic Spectrum by first explaining what it is and then identifying the range of the spectrum that is utilized in modern communication technologies.

The Electromagnetic Spectrum is a range of all possible frequencies of electromagnetic radiation, which includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. This spectrum is an essential concept in physics and is used to understand and explain the properties and behavior of electromagnetic waves.

In modern communication technologies, electromagnetic waves are used to transmit information over long distances. The specific range of the spectrum utilized in communication technologies is known as the radio frequency (RF) spectrum. It includes frequencies from 3 kHz to 300 GHz, and it is divided into different bands for various applications.

To better understand the utilization of the RF spectrum in modern communication technologies, I have gathered secondary data in the form of a table and a graph. The table below shows the different frequency bands within the RF spectrum and their applications in communication technologies.

Frequency Band | Frequency Range (Hz) | Applications
-------------- | --------------------- | ------------
Very Low Frequency (VLF) | 3,000 - 30,000 | Long-range communication with submarines and ground penetrating radar
Low Frequency (LF) | 30,000 - 300,000 | AM radio broadcasting and navigation systems
Medium Frequency (MF) | 300,000 - 3,000,000 | AM radio broadcasting and aviation communication
High Frequency (HF) | 3,000,000 - 30,000,000 | Shortwave radio broadcasting, amateur radio, and long-distance communication
Very High Frequency (VHF) | 30,000,000 - 300,000,000 | FM radio broadcasting, television broadcasting, and air traffic control
Ultra High Frequency (UHF) | 300,000,000 - 3,000,000,000 | Mobile phones, Wi-Fi, and satellite communication
Super High Frequency (SHF) | 3,000,000,000 - 30,000,000,000 | Satellite communication, radar, and microwave ovens
Extremely High Frequency (EHF) | 30,000,000,000 - 300,000,000,000 | Radio astronomy, remote sensing, and satellite communication

From the table, we can see that the RF spectrum is utilized in a
