HSUPA (High Speed Uplink Packet Access):
Advanced WCDMA that delivers
uplink bandwidth intensive data at up to 5.76Mbps; typically associated with
3.75G.
HSPA+ (High Speed Packet ):
This is also known as HSPA Evolved, is the
next step and is more focused on delivering data services enabling speeds of up
to 42Mbps in the downlink and 11Mbps in the uplink.
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.
IPSec (Internet Protocol Security):
Security implementation of IP communications
by authenticating and encrypting each IP packet during network communication.
Kbps (Kilobits per second):
A data flow measure; 1024 bits/second.
LAN (Local Area Network):
A data network with limited range but good bandwidth.
Load Balance:
A method for distributing network loads across different networks to
optimize network traffic flow and increase network reliability.
LTE (Long Term Evolution):
High-speed mobile communication standard based on
the GSM/EDGE and UMTS/HSPA network technologies. LTE provides downlink
peak rates up to 300 Mbit/s and uplink peak rates up to 75 Mbit/s.
Mbps (Megabits per second):
A data flow measure; 1,048,576 bits/second.
MDN (Mobile Directory Number):
The telephone number of the mobile device. In
other words, it is the directory number that is assigned to a mobile subscriber.
MSID (Mobile Station Identification):
The identification number for the mobile
station. The
MSID
can be a
MIN (Mobile Identification Number)
or
IMSI
(International Mobile Subscriber Identity)
.
MSL (Maximum Segment Lifetime):
The maximum amount of time (arbitrarily
defined as 2 minutes) that a TCP segment can exist in the internetwork system.
PAP (Password Authentication Protocol):
The difference between PAP
authentication and a manual or scripted login, is that PAP is not interactive. The
username and password are entered in the client's dialing software and sent as
one data package as soon as the modems have established a connection, rather
than the server sending a login prompt and waiting for a response.
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.
Tx:
Shorthand for Transmission.
