Term Definition
GPRS
General packet radio service (GPRS) is a packet oriented mobile data service on the 2G and
3G cellular communication system’s global system for mobile communications (GSM).
GPS
The Global Positioning System (GPS) is a space-based satellite navigation system that pro-
vides location and time information in all weather conditions, anywhere on or near the Earth
where there is an unobstructed line of sight to four or more GPS satellites.
GSM
Global System for Mobile Communications (GSM) is a standard set developed by the
European Telecommunications Standards Institute (ETSI) to describe protocols for second
generation (2G) digital cellular networks used by mobile phones.
Hz
Hertz. The international unit for measuring frequency, equivalent to the older unit of cycles per
second. One megahertz (MHz) is one million hertz. One gigahertz (GHz) is one billion hertz.
The standard US electrical power frequency is 60 Hz, the AM broadcast radio frequency band
is 535—1605 kHz, the FM broadcast radio frequency band is 88—108 MHz, and wireless
802.11b/g LANs operate at 2.4 GHz.
HSDPA
High-Speed Downlink Packet Access (HSDPA) is an enhanced 3G (third generation) mobile
telephony communications protocol in the High-Speed Packet Access (HSPA) family,
also dubbed 3.5G, 3G+ or turbo 3G, which allows networks based on Universal Mobile
Telecommunications System (UMTS) to have higher data transfer speeds and capacity.
Current HSDPA deployments support down-link speeds of up to 42 Mbit/s.
HSPA
High Speed Packet Access (HSPA) is an amalgamation of two mobile telephony proto-
cols, High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access
(HSUPA), that extends and improves the performance of existing 3rd generation mobile tele-
communication networks utilizing the WCDMA protocols.
HSUPA
High-Speed Uplink Packet Access (HSUPA) is a 3G mobile telephony protocol in the HSPA
family with up-link speeds up to 5.76 Mbit/s.
HTTP
The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collabora-
tive, hypermedia information systems, and is the foundation of data communication for the
World Wide Web. Hypertext is a multi-linear set of objects, building a network by using logi-
cal links (the so-called hyperlinks) between the nodes (text or words). HTTP is the protocol to
exchange or transfer hypertext.
IANA
The Internet Assigned Numbers Authority (IANA) is the entity that oversees global IP address
allocation, autonomous system number allocation, root zone management in the Domain
Name System (DNS), media types, and other Internet Protocol-related symbols and numbers.
ICMP
The Internet Control Message Protocol (ICMP) is one of the core protocols of the Internet
Protocol Suite. It is used by the operating systems of networked computers to send error
messages indicating, for example, that a requested service is not available or that a host or
router could not be reached. ICMP can also be used to relay query messages. It is assigned
protocol number 1.
IEEE
Institute of Electrical and Electronics Engineers, New York, www.ieee.org. A membership
organization that includes engineers, scientists and students in electronics and allied fields.
It has more than 300,000 members and is involved with setting standards for computers and
communications.
IMEI
The International Mobile Station Equipment Identity (IMEI) is a number, usually unique, to
identify 3GPP and iDEN mobile phones, as well as some satellite phones. It is usually found
printed inside the battery compartment of the phone, but can also be displayed on-screen.
IMSI
The International Mobile Subscriber Identity (IMSI) is a unique identification associated with
all cellular networks. It is stored as a 64 bit field and is sent by the phone to the network. It
is also used for acquiring other details of the mobile in the home location register (HLR) or
as locally copied in the visitor location register. To prevent eavesdroppers identifying and
tracking the subscriber on the radio interface, the IMSI is sent as rarely as possible and a ran-
domly generated TMSI is sent instead.
I/O
Input / Output. The term used to describe any operation, program or device that transfers
data to or from a computer.
