5.A) Read this text and answer the questions. Range
Wireless networks have limited range. Network range
1.How many things does network range depend on? Network range depends on the type of 802.11 protocol, strength of the device transmitter and the architecture of the surrounding area. 2.What can reduce network range? Some structures, such as walls and metal frames, reduce the range 3.What can improve network range? Users can extend the range of a WLAN. Repeaters forward the wireless signal to access points or routers and increase the range of a network. 4.What two things affect speed? Bandwidth and latency are the measures of computer network speed, or data transfer rate.

K: How do you describe network speed?
S: In bits, kilobits, megabits and gigabits. They describe network speed. Bits, kilobits, megabits and gigabits describe network speed. T/F
Dial-up connections allow from 512 kilobits per second to 3 megabits per second. T/F
Metric and feet describe network range T/F
Home networking routers support a range up to 150 feet or 46 metres outdoors. T/F
Home networking routers support more range outdoors. T/F
