Important Safety Information and Glossary
3.5G/ HSPA: A more recent standard of mobile networking technology;
generally uses HSDPA
3.75G/ HSPA: A more recent standard of mobile networking
technology; generally uses HSUPA
4G/LTE: LTE is the next-step of the evolution of UMTS (3G) and
HSDPA (3.5G), now known as 4G.
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.
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 downlink bandwidth intensive data at up to 7.2Mbps;
typically associated with 3.5G.
HSUPA (High Speed Uplink Packet Access): Advanced WCDMA
that delivers uplink bandwidth intensive data at up to 5.76Mbps;
typically associated with 3.75G.
3.75G/HSPA+ (High Speed Packet ): This is also known as
HSPA Evolved, is the next step and is more focused on delivering data
service enabling speeds of up to 42Mbps in the downlink and 11Mbps
in the uplink..
LTE(long term evolution): LTE is the next-step of the evolution of
UMTS (3G) and HSDPA (3.5G), now known as 4G. that delivers
downlink bandwidth intensive data at up to 100Mbps and uplink
bandwidth intensive data at up to 100Mbps
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.
NDIS (Network Driver Interface Specification): a Windows device
driver interface that enables a single network interface card to support
multiple network protocols.
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.
EVDO (Evolution-Data Optimized) Rev. A: The EV-DO feature of
CDMA2000 networks provides access to mobile devices with forward
link air interface speeds of up to 3.1 Mbit/s.
