Range

Wireless networks have limited range. Network range depends on the type of 802.11 protocol, the strength of the device transmitter and the architecture of the surrounding area. Some structures such as walls and metal frames reduce the range of a WLAN by 25%. However, 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.

Speed

Bandwith and latency are the measures of computer network speed, or data transfer rate. Bandwidth is the maximum throughput of date in bits per second. Some modems support 100 Gbit/s but speed depends on the hardware and software used. Latency is the delay that network creates during the transfer of data. Users have no or very little control over bandwidth and latency.

26 Wireless networks don’t have a wide range. ( T / F )

27 Network range depends on different factors. ( T / F )

28 Walls and metal frames can increase the range of a WLAN. ( T / F )

29 It’s possible to increase the range of a WLAN. ( T / F )

30 Data transfer rate is measured in bandwidth and latency. ( T / F )

31 The minimum throughput of data in bits per second is the latency. ( T / F )

32 Speed depends only on the hardware used. ( T / F )

33 Users can control the latency. ( T / F )
