TCP/IP
Transmission Control Protocol/Internet Protocol. Protocol family on which the Internet
is based. IP forms the basis of each PC to PC connection. TCP provides applications
with a reliable transmission link in the form of a continuous data stream. TCP/IP is the
basis on which services such as WWW, Mail and News are built. There are other pro-
tocols as well. In order to access the Internet from a PC, TCP/IP must be set up on the
PC.
UDP
User Datagram Protocol. UDP is a Protocol of the TCP/IP protocol family that handles
data transport between two communication partners (applications). Unlike TCP, UDP
is a non-session based protocol. It does not establish a fixed connection. The recipient
is responsible for making sure the data is received. The sender is not notified about
whether it is received or not.
Uplink
Data that your SX682 WiMAX forwards from your PC or local network to external sites
(e.g. to the Internet).
URL
Universal Resource Locator. Globally unique address of a domain on the Internet, e.g.
http://www.sagemcom.com.
Virtual server
A virtual Server provides a service on the Internet that runs not on itself, but on another
network component. The SX682 WiMAX can be configured as a virtual server. It will
then direct incoming calls for a service via Port forwarding directly to the appropriate
Port of the network component in question.
VoIP
Voice over Internet Protocol; voice transmission via the Internet (Internet telephony).
WAN
Wide Area Network. A WAN is a network that is not restricted to one particular area,
such as the Internet. A WAN is run by one or more public providers to enable private
access. You access the Internet via a Provider.
WiMAX
Worldwide Interoperability for Microwave Access. WiMAX is a modern wireless net-
work technology that enables fast Internet connection even in remote areas where no
other connection possibility (e. g. DSL) is available.
