Radio
The radio system is one type of wireless data transmission, and it is a wireless media that transfers data by carrying electromagnetic waves with low frequencies to distant locations through an electrical conductor and an antenna. Ham radio enthusiasts share information and serve as emergency communication aids during disasters with their powerful amateur broadcasting equipment and can even communicate digital data over the radio spectrum.
Citizen’s band and maritime radios provide communication services for truckers and sailors. The transmission frequency for information transmitted through a radio system ranges from 10 kilohertz (kHz) to 1 gigahertz (GHz), and the frequencies are regulated by the Federal Communications Commission (FCC).

Wireless Phones
The evolution of cellular networks is enumerated by generations. Many different users communicate across a single frequency band through Cellular and cordless phones. Cellular and cordless phones are two more examples of devices that make use of wireless signals.
Cordless phones have a limited range but cell phones typically have a much larger range than the local wireless networks since cell phone use large telecommunication towers to provide cell phone coverage. Some phones make use of signals from satellites to communicate, similar to Global Positioning System (GSP) devices.
Wireless Phones
Other Devices
Anything that uses radio signals to communicate can be considered as a wireless device. Common devices such as garage door openers, baby monitors, certain video game consoles and walkie-talkies make use of wireless technology.
Advantages
· Any information can be conveyed or transmitted quickly and with a high speed.
· The Internet can be accessed from anywhere and at anytime without the need to carry cables or wires and it improves easy access and productivity.
· Helpful for Doctors, workers and other professionals working in remote areas as they can be in touch with the medical centers through wireless communication.
· Emergency situations can be alerted through wireless communication. The affected regions can be provided support with the help of these alerts through wireless communication.
· Wireless networks cost less for installation and maintenance.
Disadvantages
· A Hacker can easily capture the wireless signals that spread through the air.
· It is very important to secure the wireless network so that the information cannot be exploited by unauthorized users, and this also increases the risk of losing data or information.
Thus, Wireless networks are one of the fastest growing technologies in telecommunications market. WiMax, Bluetooth, Wi-Fi, Femtocell and 4G are some of the most significant standards of Wireless technology for the next generations. Radio, Mobiles, Internet, etc., all use technological advancements in wireless data transmission systems that carry invisible electromagnetic waves to transmit data over long distances within a short amount of time.
