RF network can pass through the building and house walls, making it an excellent choice for mobile and television communications.

Fremont, CA: Radio Frequency technology refers to wireless electromagnetic impulses utilized as a means of communication. Technology is helpful to communicate via mobile phones, computers, and television broadcasts. RF propagation happens at the speed of light and does not require a medium such as air to propagate. Wi-Fi in the house also employs RF transmission to link two gadgets or PCs.

There are several advantages to using an RF network. It can pass through the building and home walls, making it an excellent choice for mobile and television communications. RF is also utilized for MRI scans to obtain pictures of bodily organs and in surgical diathermy devices. It has a wide range of uses in healthcare, hospitals, and medicine.

The technology is also very simple to install and has a very minimal installation cost. One of the benefits of RF technology is its ability to be used effectively in military operations. For example, RF is employed in radars to monitor enemy movements as well as in satellite communication. When the line-of-sight connection between satellites gets disrupted due to the earth's rotation, they communicate via Radio Frequency, preventing any communication outage.

However, along with a slew of benefits, RF technology has a few drawbacks. For example, excessive radiation from RF can be hazardous to pregnant women, pre-adolescent children, cardiac patients with pacemakers, and the environment. In addition, according to a study, RF cellular towers are more vulnerable to lightning strikes than regions without such towers.

Furthermore, RF transmission is vulnerable to hacking. Meanwhile, to prevent RF network hacking, transmission is done utilizing a variety of highly secure algorithms such as Advanced Encryption Standards (AES), Wired Equivalent Privacy (WEP), and Wi-Fi Protected Access (WPA). Furthermore, to avoid being hacked, the RF broadcast can be modified using frequency-hopping.

With technological breakthroughs, smart gadgets based on the Internet of Things (IoT) and Artificial Intelligence (AI) are now available. These smart gadgets communicate with one another over an RF network. These gadgets simplify people's lives; with updated technology, the disadvantages can get reduced even more.
