Glossary
● 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.
● EDGE — Enhances Data rates for GSM Evolution. A digital mobile phone technology that allows
improved data transmission rates as a backward-compatible extension of GSM.
● 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
information, visit www.cdg.org.
● 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.
● GPRS — General Packet Radio Service. A packet oriented mobile data service on the 2G and 3G
cellular communication system’s global system for mobile communications (GSM).
● GSM — A computer program embedded in an electronic device. Firmware usually contains operating
code for the device.
● Hotspot — A Wi-Fi (802.11) access point or the area covered by an access point. Used for connecting
to the Internet.
