Wi-Fi is short for “Wireless Fidelity”(无线上网). It allows laptop computers and personal digital assistants to connect to the Internet at high speed by radio sigal.

A person with a Wi-Fi enabled computer can connect to the Internet when near one of the network’s access points. The place covered by one or several access points is called a hotspot. Google had already set up two “hotspots” in the US city of San Francisco which provide a free Wi-Fe service.

The Wi- Fi technology even allows users to enjoy a free Internet phone service. Some scientists argue that Wi-Fi may replace mobile phone networks.

Wi-Fi is stioo limited to a few cities, where there are “ hotspots”. But its capability(容量) of sending information has already done better than that of the mobile phone network, even that of 3G (Third Generation telecommunication technology). Some scientists have started to call Wi-Fi 4G.

In addition to a high speed Internet connection, Fi-Fi has other advantages compared to mobile phones. We-Fi is global. The same Wi-Fi system works in different countries around the world. Different from using cell phones, you don’t need to change computers to use Internet phones when you go to other places and most importantly, many Internet phones cost you nothing at all.

Wi-Fi is not available in cities without_____.

A. a computer B. a radio C. a hotspot D. a cell phone

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.
