Mobile Networking

Question 1

first group of networking technologies applied to mobile devices, it relied on TDMA and introduced SIM cards; considered 2G technology

Answer 1

Global System for Mobile Communications (GSM)

Question 2

type of multiplexing where mutliple users could share a channel at seemingly the same time by switching between users so fast to appear unnoticable

Answer 2

time-division multiple access (TDMA)

Question 3

one of the last GMS standards, it offered data speed of up to 384 Kbps

Answer 3

Enchanced Data rates for GSM Evolution (EDGE)

Question 4

mobile networking technology that used a spread spectrum form of transmission, having users assigned different frequencies rather than splitting a channel into time slices; lacked SIM cards

Answer 4

Code-division multiple access (CDMA)

Question 5

final 3G standard of mobile networking technologies, it provided theoretical speeds of up to 168 Mbps, though rarely exceeded 10 Mbps; it supported the IMT-2000 standard with higher speeds, support for full-time Internet connections, and other functions

Answer 5

Enchanced High-Speed Packet Access (HSPA+)

Question 6

mobile networking technology marketed as 4G technology, it features speeds up to 300 Mbps download and 75 Mbps upload, and it uses SIM cards

Answer 6

Long Term Evolution (LTE)

Question 7

security mode for Bluetooth devices that prevents the device from being visible unless the mode is turned on, and that for only a limited time

Answer 7

discovery/discoverable mode

Question 8

process of sending unsolicited message to another Bluetooth user

Answer 8

Bluejacking

Question 9

process of using a weakness in the Bluetooth standard to steal information from other Bluetooth devices

Answer 9

Bluesnarfing

Question 10

Bluetooth security vulnerabilities published in 2017

Answer 10

BlueBorne

Question 11

low speed, short range technology designed for monetary transactions; usually consists of an tag that stores private data and a reader; uses the 13.56 MHz band; can limit connection as little as 5 cm

Answer 11

Near field communication (NFC)

Question 12

technology standards similar to NFC that uses a range of frequency bands from 120 KHz to 10 GHz; has broader applications than NFC; must be within 1 meter, has weak to no encryption, and used often in tags

Answer 12

radio-frequency identification (RFID)

Question 13

communication that consists of an infrared light-emitting device and another device that reads the code; used often in remotes

Answer 13

Infrared (IR)

Question 14

infrared transmitter than can emulate any IR remote

Answer 14

IR blaster

Question 15

low speed, low powered communication technology similar to NFC; used in situations where it can go long periods of time without transmitting data, require low power, and is not needed to transmit a lot of data; used in heart-rate monitors; not found in Apple phones and only in some Android phones; encrypted with AES

Answer 15

Adaptive Network Technology (ANT+)

Question 16

process of controlling lights, thermostats, cameras, and even washers remotely

Answer 16

home automation

Question 17

deployment model where employees’ own mobile devices are used by the corporation; requires tight controls and separation of personal/corporate data

Answer 17

bring your own device (BYOD)

Question 18

deployment model where the corporation owns all devices and is responsible for the maintenance of them; very strict in what is put on them

Answer 18

corporate-owned business only (COBO)

Question 19

deployment model where the corporation owns all devices and is responsible for the maintenance of them; employees are provided a list of whitelisted applications that they may install

Answer 19

corporate-owned, personally-enabled (COPE)

Question 20

deployment model where employees are provided a choice from a catalog of mobile devices; company owns the device, but employee can install their own apps

Answer 20

choose your own device (CYOD)

Question 21

process of making sure new mobile devices in an company’s infrastructure are secure and safe to use inside

Answer 21

on-boarding

Question 22

process of making sure that mobile devices that leave a company’s control no longer store proprietary apps or data

Answer 22

off-boarding

Question 23

process of using a mobile device’s GPS capabilities and networking capabliities to set constraints on where it can be used

Answer 23

geofencing
