Imagine that you are sitting in a park and suddenly remember that you need to send an urgent email. You have your laptop computer with you and you connect it to a wireless access point and access the Internet. Then you send your email. This wouldn’t have been possible if there were no wireless Internet for laptops. Wireless Internet has come into our life in so many ways that we don’t even realize what a necessary part it has become of our day-to-day lives.
How do we connect to a wireless Internet service for laptop computers? There are two ways to do this. They are Wi-Fi connection and Bluetooth connection. Wireless networking is very easy. You just switch on the Wi-Fi button that has been provided in the laptop for Wi-Fi scanning. Once that is done, the computer will connect to the Internet.
An interesting fact about Wi-Fi networking is that you can create a network between similar wireless equipment. Consider a situation where you and your friend both have Wi-Fi laptops, and there is some data you want to exchange. Traditional networking architecture demands that you have a wireless router (路由器). But the beauty of Wi-Fi networking technology is that you can set up a network between you and your friend’s laptop, and share all the data you want.
Broadband (宽带) Internet connection is typically preferred by any user as it provides better speed for Internet surfing. Up until the invention of 3G mobile phones, Internet speed on mobile phones was very slow. 3G has the promise of changing the entire face of broadband technology. Just imagine browsing at speeds of more that 2MB per second. To give you a measure of the speed, 3G enables you to watch high quality live videos on the Internet.
It is amazing to see how technology changes and the rate at which it changes. There may come a time when you may be able to browse using mobile wireless Internet for laptops anywhere in the world.

Is it wrong to use someone else’s wireless (Wi-Fi) connection? Just recently, a man was arrested for doing just that. At that time, he was sitting in the street with a laptop(便携式电脑) and using an unsecured(无安全保护措施) wireless connection to surf the Net. What do you think about this topic? Listen to the following different views on it.
For a start, if someone is using your Internet service or downloading, this will affect your speed of access or download limit. Also, it’s bad for Internet service providers. They will suffer in the long run because fewer people will pay for an Internet service if they know they can get it for free. And finally, just imagine this: what if the person who is stealing your Internet connection is involved in an illegal activity? I think the police are totally right to arrest these criminals.

Basically, if the person who paid for the service still has everything they paid for, what’s the problem? It’s just like using the light from streetlamps to read your book, or watching someone else’s firework display. It’s not stealing.
Also, if you leave your wireless connection unsecured, then it is your own fault(过错) if someone else uses it. Just as you wouldn’t leave your front door unlocked, or your car door open, neither should you leave your wireless connection open. By leaving your wireless connection open, you are inviting people to use it. Securing your wireless connection is as easy as clicking a few settings on your router(路由器). And finally, haven’t the police got more important crimes to solve? They’re always saying how they haven’t got the manpower to solve real issues. But this is just ridiculous(荒谬的).
