Wireless Technology Works - But What Are the Mechanics Behind It?

If you're a typical family, you have computers, cellphones, iPods and iPads, as well as other wireless devices. Mom is shopping over the internet, Dad is conferencing on Skype, and of course kids are texting their friends every chance they get. Welcome to the wireless world. If you're like millions of people who have a computer, you know how important it is to have a reliable, quality internet service provider. If you're a business, it's crucial to have a internet provider that works hard to make sure you're up and running. So, what are the mechanics behind wireless technology?

Wireless communications, the transfer of information between two or more points not physically connected, has taken center stage in the last couple of decades with TV remote controls, headphones, broadcast TV, and cordless telephones. Wireless technology can be short or long distances--such as deep space radio communications. Just recently, wireless communications have exploded in the last five years, especially regarding cellphones and portable electronic devices.

Telecommunications is the term commonly used for transferring information without wires over local or long distances. Cellphones work through radio waves or radio towers that are built all over the world. They allow their users to make phone calls from many locations worldwide. They can be used within range of the towers, which house the equipment required to transmit and receive the radio signals from these instruments. Internet service provider companies have been created to handle the vast amount of internet users.

Other wireless devices include:

  • A remote control, which sends control command information to your TV, commanding it to go to whatever channel you want, or to turn it on, off, control the volume, or even mute the sound
  • A remote garage door opener that sends the same commands to a garage door to open or close it
  • A wireless sound system, which sends information either from music or a TV┬áto your wireless headphones or speakers.
  • A wireless network-connected laptop computer, which send and receives data, allowing it to communicate with other computers on the network.

More recently, another technology has surfaced. Wi-Fi, is a wireless, local area network that allows the user to connect to the internet. Just like a DSL signal, WI-Fi has different speeds, depending on distances and obstructions that the radio waves signal encounters. An access point is a hub that allows for coordinating network traffic to multiple clients. Many businesses use this tool for their customers, particularly in restaurants, bookstores and offices. Mobile Satellite communications are used mainly in large rural areas or remote locations.

Bluetooth is also a fairly new wireless technology that uses low-power radio communications to link phones, computers and other technological devices over short distances without wires. It was designed for personal computer devices, such as cell phones, PDAs, and wireless headsets; it usually covers a short distance of no more than 30-feet.
