●
1X
— Internet at 1/10 the speed of EV-DO.
●
3G
— Third Generation. 3G refers to the third generation of mobile telephony technology.
●
4G LTE
— Fourth Generation. 4G LTE refers to the fourth generation of mobile telephony technology.
●
802.11 (b, g, n)
— A set of WLAN communication standards in the 2.4, 3.6 and 5 GHz frequency bands.
●
bps
— Bits per second. The rate of data flow.
●
Broadband
— High-capacity high-speed transmission channel with a wider bandwidth than
conventional modem lines. Broadband channels can carry video, voice, and data simultaneously.
●
CDMA
— Code Division Multiple Access. It is the underlying channel access method used by some
mobile phone standards.
●
DHCP
— Dynamic Host Configuration Protocol. Software found in servers and routers that
automatically assigns temporary IP addresses to clients logging into an IP network.
●
DHCP Server
— A server or service with a server that assigns IP addresses.
●
DNS
— Domain Name System. A system for converting host names and domain names into IP
addresses on the Internet or on local networks that use the TCP/IP protocol.
●
EV-DO Rev 0
— CDMA EV-DO Rev. 0 is a leading-edge wireless technology with higher data rates and
higher system capacity. It is a fully backward compatible standard and remains interoperable with
deployed EV-DO networks and devices around the world. Rev 0 provides access to mobile devices
with forward link speeds of up to 2.4 Mbit/s, and reverse link speeds up to 152 kbit/s. For more

EV-DO Rev A
— CDMA EV-DO Rev. A is a leading-edge wireless technology with higher data rates and
higher system capacity. It is a fully backward compatible standard and remains interoperable with
deployed EV-DO networks and devices around the world. Rev A provides access to mobile devices
with forward link speed of up to 3.1 Mbit/s, and reverse link speeds up to 1.8 Mbit/s. The increased
data rates on Rev. A’s physical layer enable richer applications and services. For more information, visit

●
Firmware
— A computer program embedded in an electronic device. Firmware usually contains
operating code for the device.
●
GB
— Gigabyte. A multiple of the unit byte for digital information storage. Usage depends on context.
When referring to disk capacities it usually means 10
9
bytes. It also applies to data transmission
quantities over telecommunication circuits.
●
Hotspot
— A Wi-Fi (802.11) access point or the area covered by an access point. Used for connecting
to the Internet.
●
HTTP
— Hypertext Transfer Protocol. An application-level protocol for accessing the World Wide Web
over the Internet.
●
IEEE —
Institute of Electrical and Electronics Engineers. An international technical/professional society
