ViewSonic Wireless Media Gateway 93
Peer-to-peer network. A wireless or wired computer network that
has no server or central hub or Gateway. All the networked PCs
are equally able to act as a network server or client, and each client
computer can talk to all the other wireless computers without
having to go through an access point or hub. However, since there
is no central base station to monitor traffic or provide Internet
access, the various signals can collide with each other, reducing
overall performance.
PHY (Physical Layer). The lowest layer within the OSI Network
Model. It deals primarily with transmission of the raw bit stream
over the PHYsical transport medium. In the case of wireless LANs,
the transport medium is free space. The PHY defines parameters
such as data rates, modulation method, signaling parameters,
transmitter/receiver synchronization, etc. Within an actual radio
implementation, the PHY corresponds to the radio front end and
baseband signal processing sections.
Proxy server. Used in larger companies and organizations to
improve network operations and security, a proxy server is able to
prevent direct communication between two or more networks. The
proxy server forwards allowable data requests to remote servers
and/or responds to data requests directly from stored remote
server data.
Range. How far will your wireless network stretch? Most Wi-Fi
systems will provide a range of a hundred feet or more. Depending
on the environment and the type of antenna used, Wi-Fi signals
can have a range of up to mile.
