There was a time when the word "wireless" meant something ran on "D" size batteries. It was great for the dolls and fire engines on Christmas morning. But you are now a grownup and your life is moving faster. You want wireless electronics that will make your life easier. What you get depends on what you want to do.
When it comes to communications, cellular phones have become the most common and reliable form of wireless. There are fewer and fewer places to travel where you will not be able to have phone service. More and more, cellular phones are replacing their land-based cousins because cellular phones are convenient to carry and packed with features. These wonders of electronics also allow parents to stay in close touch with their children.
Next in communications are the wireless networks established for computer users. Laptops, PDAs and similar electronics can keep you constantly linked with your business partners through wireless Internet access. For businesses and even households with multiple computers, affordable wireless networks can be established to eliminate the tangle of copper wiring. Even the keyboard and mouse of a computer come in wireless versions to give you more freedom from your desk.
Sound electronics also have gone wireless. Speakers for stereos and home theatres come in versions, ending the need for trying to figure which wire goes where. Wireless microphones are getting smaller as they become more sensitive to sound. The original wireless -- radio -- has taken on a new life with the creation of receivers that convert digital signals sent via satellite into sharp, full sound.
Remote controls let you operate a variety of electronics from your chair. You can turn lights on or off, switch functions on your stereo and operate cameras. You can give a slide presentation at whichever rate you choose. Oh yes, you also can adjust the volume of your television, radio, home theatre and other electronics.
