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.

Lawmakers in the United States have expanded an investigation into the use of location-tracking systems on mobile devices． The action follows recent reports about the storing of information on the Apple iPhone． Some people consider location tracking to be a threat to personal privacy and security．
Allan Friedman, the research director, says, “All wireless companies do some location tracking as part of their networks． This information is usually stored by the companies, not the devices, and there are laws to protect it． Law enforcement（执法） agencies, for example, have to have a fairly high standard before it can access that data． And the phone company is also prohibited from selling that information．
Now, two researchers report that location tracking information is being stored directly on Apple devices． They said Apple’s newest operating systems gather global positioning system and timestamp information． The information is stored on the device in a file that is also uploaded （上传） to any computer that the device is connected to． The researchers say the information is available to anyone who has access to the device or computer．
Allan Friedman says, “This raises additional concerns． There’s the idea that because it’s on my phone and on my computer, rogue applications（恶意程序） that I pay for or that I’m tricked into downloading may be able to access this data and somehow misuse it．”
Apple says it is “not tracking the location of your iPhone”． It is simply keeping a database of Wi-Fi hotspots and cellphone towers near the user’s location． This information is meant to help the iPhone quickly find its location when needed．
Letters have been sent to some of the leading mobile device developers, including Apple and Google． The letters asked for more information about their location tracking systems． Allan Friedman calls this an important start to strengthening privacy laws． He says, “There aren’t strong controls over things like location information, what they are doing with it, how long they are keeping it． And perhaps the most important question is, is my location data with other facts about me?”
1.Why did American lawmakers investigate the use of location-tracking systems on cell-phones?
A.Because the systems can store users’ information
B.Because many users have suffered loss after using them．

Cellphones: is there a cancer link?
Could your cellphone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and wi-fi could be responsible for a range of illnesses, from rashes to brain tumors.
Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there’s a greater than 95 percent chance that power lines can cause childhood leukemia(白血病). Also there’s a greater than 90 percent chance that cellphones can cause brain tumors. “It’s apparent now that there’s a real risk,” said Carpenter.
But others believe these concerns are unjustified. Dr Martha Linet, the head of radiation epidemiology(流行病学) at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. “I don’t support warning labels for cellphones,” said Linet. “We don’t have the evidence that there’s much danger.”
Studies so far suggest a weak connection between EMFs(电磁场) and illness — so weak that it might not exist at all. A multinational investigation of cellphones and brain cancer, in 13 countries outside the US, has been underway for several years. It’s funded in part by the European Union, in part by a cellphone industry group. The final report should come out later this year, but data so far don’t suggest a strong link between cellphone use and cancer risk.

BEIJING—Apple Inc is one step closer to beginning sales of iPad3 tablet computers with cellular (手机) network compatibility (兼容) for the first time in the Chinese mainland, where the consumer-electronics giant is in the midst of an aggressive expansion.
According to China’s Telecommunication Equipment Certification Center, a device by Apple with third-generation high-speed wireless data capabilities was issued the network access license needed for the company to begin official sales in China. The device, listed under model number “A1396”, is compatible with the 3G standard WCDMA, and would work with the cellular network operated by Apple’s local iPhone partner, China Unicom (Hong Kong) Ltd.
China Unicom declined (谢绝) to comment.
Apple already offers the 3G iPad3 in Hong Kong through its partners, but currently only offers Wi-Fi versions of the device in the Chinese mainland. Still, consumers in China, which according to research firm IDC surpassed (超过) the US as the world’s largest PC market in the second quarter, have been purchasing 3G tablets through unofficial channels.
Separately, Apple spokeswoman Carolyn Wu said Sept 6 that the company’s first Hong Kong store, set to open this quarter, will be located in the city’s central shopping and business district in the International Finance Center’s upscale (高档的) IFC mall, a commercial center and sightseeing spot along the city’s waterfront. Wu also said that Apple is planning a new store in Shanghai later this quarter, which will be its biggest store in China. She declined to give more details or to comment on the 3G iPad3.
Apple currently has four full-service Apple stores in the mainland, which receive the most traffic of any Apple stores in the world. The company otherwise relies on resellers to get its products into the market.
The new stores reflect Apple’s confidence in rising demand for its products such as smart phones and tablet computers. Sales in the Chinese mainland, Hong Kong and Taiwan helped boost (增长) the company’s third-quarter results, newly appointed Chief Executive Tim Cook said in July. China revenue (收益) surged (激增) six-fold to about $3.8 billion during the three months ended June 25.
“This has been a substantial (重大) opportunity for Apple and I firmly believe that we’re just scratching the surface right now,” Cook said at the time, referring to strong sales in China. “I see an incredible opportunity for Apple there.”
