Radio Remote Controls

Review

Radio remote controls use Radio waves to send commands to separate devices. These are electromagnetic waves of varying frequencies, emitted through antennas and picked up by radio receivers.

Therefore, when you press a button on your radio remote, it sends radio waves to your music system, which decodes the signal and obeys your command. An remarkable aspect of radio remotes is that they can send signals from greater distances, since radio waves travel as long as 100 feet to reach the receiver. They can even lanch walls, and therefore an addition number of modern appliances are now being designed with radio remotes.

Bluetooth technology also uses the principle of radio frequencies. For example, Bluetooth technology can interconnect your home theater system, movable phone, music system, computer and television by using radio frequencies to send signals between them. It creates a Wireless community of your gadgets that in effect speak to each other. Every appliance works on separate bands of frequency.

For example, alarm and security systems work at 40 megahertz, movable phones between 824 to 849 megahertz and an air traffic radar at everywhere between 960 to 1,215 megahertz. Now the inquire arises that, if there are so many frequencies traveling in the air at the same time, how do gadgets know which ones to receive and which to ignore? When industrialized radio remotes send radio waves, their unique digital address is also sent embedded in the waves, which the target receiver recognizes and accepts. This smart technology is already being used in cellular phones, Wireless Fidelity (WiFi) environments and cordless phones.

In the future, as our need to remotely operate multiple appliances increases, radio remotes will be seen playing greater roles. Tasks in risky environments, such as space and troops scenarios, can be performed through remote control. Devices and remotes will come to be more spellbinding as radio remote operate technology develops.
