8. Translate these passages in writing:

a) In the near future, wireless networking may become so widespread that you can access the Internet just about anywhere at any time, without using wires. WiFi has a lot of advantages. Wireless networks are easy to set up and inexpensive. They're also unobtrusive ─ unless you're on the lookout for a place to use your laptop, you may not even notice when you're in a hotspot.

b) 802.11n is the newest standard that is widely available. This standard significantly improves speed and range. For instance, although 802.11g theoretically moves 54 megabits of data per second, it only achieves real-world speeds of about 24 megabits of data per second because of network congestion. 802.11n, however, reportedly can achieve speeds as high as 140 megabits per second. The standard is currently in draft form ─ the Institute of Electrical and Electronics Engineers plans to formally ratify 802.11n by the end of 2009.

10. Decide whether the following statements are true (t) or false (f) in the relation to the information in the first and the second parts of text 2.

1.	□	Some cities are trying to use WiFi technology to provide free or low-cost Internet access to residents.
2.	□	WiFi has only one advantage.
3.	□	WiFi networks are very difficult to set up, they are expensive and obtrusive.
4.	□	A wireless network uses radio waves, just like cell phones and radios do.
5.	□	WiFi radios transmit at frequencies of 2.4 GHz or 10 GHz.
6.	□	The higher frequency allows the signal to carry less data.
7.	□	802.11 networking standards come in several flavors.
8.	□	802.11a is the slowest and least expensive standard.
9.	□	802.11n is the newest standard that is widely available and significantly improves speed and range.
10.	□	Frequency hopping can`t reduce interference and doesn`t let multiple devices use the same wireless connection simultaneously.
