Wireless

Wireless communication is the transfer of info. over a distance without the use of electrical conductors or "wires".The distances involved may be short (a few meters as in television remote control) or long (thousands or millions of kilometers for radio communications). When the context is clear, the term is often shortened to "wireless". Wireless communication is generally considered to be a branch of telecommunications.

How does built-in wireless connection work in a laptop?

I understand that I can get wireless internet connection if my laptop has a built-in wireless card for as long as I'm in a "hotspot" where I get connection from radio waves. How true is that? I am planning to get a laptop, but I'm not sure if where we live now is actually a "hotspot" or not where I could use it for regular web surfing? We do have broadband internet for our desktop now, but I don't want to have a wireless router connected to that as it is connected to my work/company's computer, I trust wired network better for that. If there is a DSL or Cable internet provider in our area, will that give a big possibility that I will be able to get good signal for the laptop's wireless internet connection? Where do built-in wireless cards get their signals anyway? Is it possible that I will be getting a signal from other people's wireless connection? Can anyone explain this to me? I'm all confused.

What signals are boosted by a wireless extender?

It won't repeat anything other than the one network it's programmed to. They don't have to be the same brand as the router but that makes getting help easier - then you can call the one company instead of playing ring-around-the-phone to find a tech who'll help you.
Basically, it picks up the wireless network it's programmed to - just like your computer. Then, it re-broadcasts it just like you main router but from a different location. Some support full encryption, others don't so read the box to make sure it supports both WEP and WPA-PSK. The one draw-back is because it has to recieve and then re-transmit everything, it cuts the speed by half...but that's not a problem for most people because internet is still the slowest link in the chain. I have a Belkin WURE (Wireless Universal Range Extender) and it works well with all encryption but the directions were worthless so I had some trouble setting it up.
