switchover from analog to digital; most 2G networks use GSM.
3G: Third-generation mobile networking technology that enables
simultaneous transfer of voice and non-voice data; most 3G networks
use WCDMA.
3.5G: A more recent standard of mobile networking technology;
generally uses HSDPA.
APN (Access Point Name/Network): Provides GPRS routing
information. Consists of:
Network ID: Identifies the external service requested by a GPRS
user.
Mobile network operator ID: Specifies routing information.
ARFCN (Absolute Radio Frequency Channel Number): The
specific ID numbers for all radio channels used in cellular mobile
communications.
Bps (bits per second): How data flow is measured.
DNS (Domain Name System): Helps route network traffic by making
the addressing process more user-friendly.
DHCP (Dynamic Host Configuration Protocol): How devices obtain
IP addresses from a server.
DUN (Dial-Up Network): Windows component that enables online
access via a modem.
EDGE (Enhanced Data GSM Environment/Enhanced Data for
Global Evolution): Advanced GPRS that delivers multimedia and
other data needing greater bandwidth at up to 237 kbps.
GPRS (General Packet Radio Service): Delivers data in packets at
up to 86 kbps.
GSM (Global System for Mobile Communications): The most
popular cellular network, mostly operates in 850-900 or 1800-1900
MHz; the primary 2G system.
IMEI (International Mobile Equipment Identity): A number unique to
each GSM/UMTS device that can be used block network access by a
stolen mobile device.
IP (Internet Protocol): Routes packets over a network.
HSDPA (High Speed Downlink Packet Access): Advanced WCDMA
that delivers bandwidth intensive data at up to 7.2Mbps; typically
associated with 3.5G.
Kbps (Kilobits per second): A data flow measure; 1024 bits/second.
LAN (Local Area Network): A data network with limited range but
good bandwidth.
Mbps (Megabits per second): A data flow measure; 1,048,576
bits/second.
PPP (Point-to-Point Protocol): An internet connection method.
PIN (Personal Identity Number): Four to eight digital numbers SIM
card security code; allows access to the carrier’s network.
Rx: Shorthand for Reception.
SIM (Subscriber Identity Module): A small card that contains key
mobile device identification, subscription and contact information.
SMS (Short Messaging Service): Allows text messages of up to 160
characters.
Tx: Shorthand for Transmission.
UMTS: Universal Mobile Telecommunications System is one of
the third-generation (3G) cell phone technologies
WCDMA (Wideband Code Division Multiple Access): Advanced
EDGE that supports 384kbps data flow. Most 3G networks use this
standard; aka UMTS.
