The Lay Of The LAN: About Wireless Networking
Technology changes so fast, full of jargon and anocryms, that it can seem a little scary trying to keep up. But wireless networking isn't anything to be afraid of. Unlike 8-track tapes, this technology has all the makings of sticking around for a long time. Buying wireless networking devices and services is a wise investment for individuals and businesses. Even if you are a "newbie", you should be able to get the hang of wireless networking (nicknamed WiFi)in a shorter time than it takes to learn how to ride a bike.
What Is It?
A wireless local area network (called WLAN or LAN) is very much like a local radio station. It uses antennas and electromagnetic waves instead of cables or phone lines in order to send and receive information. If you have the technology, you can pick up these transmissions. It is illegal to pick them up all on your own, such as with cable TV, so you will need to hire the services of a wireless network. Often your cable or phone company will offer wireless networking services.
What Do You Need?
If you buy a new phone, laptop or PDA (personal data assistant), they will have wireless networking adapters included. If you have an older model, then you can try a WiFi adapter, which isn't entirely wireless, but close enough. You then need the services of a wireless networking provider and to have those bills paid. You then need a wireless internet card (which fits into a slot in your phone or laptop or even your computer game console) and a hotspot.
What's a hotspot? It's a place where you can receive WiFi signals. Like with radios, you might need to physically move your device around a room to find the best reception. These hotspots are often strongest in airports, libraries and internet cafes. You can pick them up in your home, but keep in mind that buildings and trees can interfere with transmission. If you are getting wireless networking for your business, with many devices linked together, be sure you keep positions of walls and doors to a minimum.
Stay Safe
Your wireless networking service should contain security precautions like ways to encrypt your emails so that no one else on your network can listen in. Installing and regularly updating a firewall also helps a lot with your security. Also, use your common sense. Don't leave your laptop where someone can steal it and never tell anyone your password or user names.
