Rekey interval

The rekey interval is the period after which new keys are automatically generated for

data encryption with WPA-PSK.

Remote management

Remote management refers to the ability to manage a network from a network compo-

nent that is actually outside the local network (LAN).

Repeater

A repeater extends the range of a wireless local network by relaying data from the

Access point to additional PCs or Network adapters.

Roaming

Roaming extends the range of a wireless LAN by using several Access points that use the

same SSID and the same radio channel and are linked via Ethernet. The PCs in the net-

work can switch dynamically between several access points without losing the existing

network connection.

Router

A router directs data packets from one local network (LAN) to another via the fastest

route. A router makes it possible to connect networks that have different network tech-

nologies. For example, it can link a local network with Ethernet or WLAN technology to

the Internet.

"server" is often used to refer to a computer or PC. However, it can also mean an appli-

cation that provides a particular service such as DNS or a Web service.

Session Initiation Protocol

SIP is a standard for data transfer in Internet telephony (VoIP). It describes how a call is

carried over the data network and which components plus which transport and signal-

ling protocols are involved.

SIP proxy server

The SIP proxy server sets up the connection to the Internet for Internet telephony (VoIP)

for all connected SIP clients.

SIP client

A SIP client enables Internet telephony (VoIP). It can be installed as software on a PC and

thereby enable Internet telephony via the local network in wireless or wired mode. Wire-

less SIP phones (WLAN handsets) can likewise be used via the local network for Internet

telephony.
