Firewall A network node that prevents traffic from one segment of a
network from crossing over into another. Firewalls are used
to protect internal systems from unauthorized external
access.
Flash Memory A memory feature or component which calls your mobile
device to save information without power.
GPRS General Packet Radio Service represents the first
implementation of packet switching within GSM, which is
essentially a circuit switched technology. Rather than
sending a continuous stream of data over a permanent
connection, packet switching only utilizes the network
when there is data to be sent. Using GPRS will enable users
to send and receive data at speeds up to 115kbits/sec
GSM Global System for Mobile Communications. Digital
cellphone system used through Europe based on TDMA
(Time Division Multiple Access - a digital communication
technology). Data transfer rates of 9.6 kbps.
Hot Sync Mode A method by which a mobile device is connected by
cradle/bay or cable to a desktop/notebook computer in order
to perform synchronizations. Synchronizations update data
or information from an external source to the mobile device.
Infrastructure The combined components needed to operate a wireless
network including sites, switching and transmission
equipment.
Interface Method or piece of equipment for interconnecting units or
systems which may not be directly compatible.
Kbps A measurement of bandwidth in the United States.
Land-Line A connection that uses land-based networks or ‘wires’.
Last Connect The last time an active connection (session) was made or
synchronization was performed.
Latency The time taken for data packets to pass through GPRS,
normally measured as a round-trip time.
m-commerce Mobile Commerce. Business transactions conducted with
online mobile devices.
Mbps Mega (million) bits per second. Measurement of
transmission speed or bandwidth.
MHz Megahertz. One million cycles per second (hertz).
Measurement of electromagnetic energy and transmission
speed (such as CPU's internal clock).
Middleware An intermediate software component located on the wired
network between the wireless appliance and the application
or data residing on the wired network.
Mobility
Ability to continually move from one location to another.
Offline mode A disconnected state that does not have an active
connection and is not receiving data or information in real-
time.
Optimization
Middleware Application software used to improve the performance of
the basic bearer (transmission provider that provides service
between user-network interfaces) service.
PalmOS® The operating system for a mobile device. There are several
device manufacturers that use this operating system.
PCMCIA
Personal Computer Memory Card International Association. A
standardized technology used to develop an expansion for portable
devices (i.e. notebooks) in paging credit card-sized support
wireless connectivity.
