Mobile Networking Flashcards
first group of networking technologies applied to mobile devices, it relied on TDMA and introduced SIM cards; considered 2G technology
Global System for Mobile Communications (GSM)
type of multiplexing where mutliple users could share a channel at seemingly the same time by switching between users so fast to appear unnoticable
time-division multiple access (TDMA)
one of the last GMS standards, it offered data speed of up to 384 Kbps
Enchanced Data rates for GSM Evolution (EDGE)
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
Code-division multiple access (CDMA)
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
Enchanced High-Speed Packet Access (HSPA+)
mobile networking technology marketed as 4G technology, it features speeds up to 300 Mbps download and 75 Mbps upload, and it uses SIM cards
Long Term Evolution (LTE)
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
discovery/discoverable mode
process of sending unsolicited message to another Bluetooth user
Bluejacking
process of using a weakness in the Bluetooth standard to steal information from other Bluetooth devices
Bluesnarfing
Bluetooth security vulnerabilities published in 2017
BlueBorne
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
Near field communication (NFC)
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
radio-frequency identification (RFID)
communication that consists of an infrared light-emitting device and another device that reads the code; used often in remotes
Infrared (IR)
infrared transmitter than can emulate any IR remote
IR blaster
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
Adaptive Network Technology (ANT+)
process of controlling lights, thermostats, cameras, and even washers remotely
home automation
deployment model where employees’ own mobile devices are used by the corporation; requires tight controls and separation of personal/corporate data
bring your own device (BYOD)
deployment model where the corporation owns all devices and is responsible for the maintenance of them; very strict in what is put on them
corporate-owned business only (COBO)
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
corporate-owned, personally-enabled (COPE)
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
choose your own device (CYOD)
process of making sure new mobile devices in an company’s infrastructure are secure and safe to use inside
on-boarding
process of making sure that mobile devices that leave a company’s control no longer store proprietary apps or data
off-boarding
process of using a mobile device’s GPS capabilities and networking capabliities to set constraints on where it can be used
geofencing
