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

This frequency wireless Band 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

Answer 5

2.4 GHz standard

Question 6

Frequency 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

measures 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

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 12

Bluetooth

Question 13

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

Answer 13

Radio Frequency ID (RFID)

Question 14

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.
