Compare Wireless Networking Types

Question 1

can establish a wireless-only (radio frequencies) network, but it can also work as a bridge to forward communications between the wireless stations and a wired
network. 802.11 IEEE

Answer 1

access point (AP)

Question 2

The MAC address of the AP’s radio is used as the?

Answer 2

Basic Service Set Identifier (BSSID)

Question 3

Every Wi-Fi device operates on a specific radio frequency range

Answer 3

Frequency Band

Question 4

frequency band is split into a series of smaller ranges
referred to as

Answer 4

Channels

Question 5

propagating through solid surfaces, giving it the longest signal range but suffer interference.
* 802.11a/g
* nominal data rate of just 11 Mbps
* subdivided into up to 14 channels
* 5 MHz

frequency wireless Band

Answer 5

2.4 GHz standard

Question 6

standard is less effective at penetrating solid surfaces and so does not support the maximum ranges achieved with 2.4 GHz standards, higher data at shorter ranges.
* 802.11a
* 54 Mbps

Answer 6

5 GHz

Question 7

allows the access point to use its multiple antennas to send data to up to four
clients simultaneously with WIFI 5

Answer 7

multiuser MIMO (MU-MIMO)

Question 8

can work alongside MU-MIMO to improve client density—sustaining high data rates when more stations are connected to the same access point w. WIFI 6

Answer 8

orthogonal frequency division multiple access (OFDMA)

Question 9

Clients identify an infrastructure WLAN through the network name

Answer 9

service set identifier (SSID)

Question 10

measure the signal strength of the different networks
using each channel.

Answer 10

Wi-Fi analyzer

Question 11

Wireless signal strength is measured in
-0db to -65db is better
-65db good
-80db suffers packet loss, be dropped

Answer 11

decibel (dB)

Question 12

comparative strength of the data signal to the background noise is called
the

Answer 12

signal-to-noise ratio (SNR)

Question 13

transmitters required to cover long distances must be carefully configured. ranges of up to about 30 miles as long as they are unobstructed by physical objects, affixed to the top of tall buildings

Answer 13

longrange fixed wireless.

Question 14

connect peripheral devices to PCs and mobiles and to share
data between two systems within a Personal Area Netwok (PAN). 10 m (30 feet) - 100 feet

Answer 14

Bluetooth

Question 15

is a means of identifying and tracking objects using specially encoded tags.

Answer 15

Radio Frequency ID (RFID)

Question 16

is a peer-to-peer version of RFID; that is, a device can work as both tag and reader to exchange information with other devices.
* used for contactless payment readers
* shop shelf-edge labels for stock control.
* pairing Bluetooth devices
* works at up to two inches (6 cm) at data rates of 106, 212, and 424 Kbps.
