Technology Systems Wireless Network Specifications
What
is wireless networking?
A wireless local-area
network (WLAN) uses Radio Frequency (RF) technology to transmit
and receive data over the air, providing all the features and benefits
of traditional LAN technologies but without the limitations of a
cable. A wireless local-area network is a flexible data communication
system implemented as an extension to, or as an alternative for,
a traditional wired local area network.
Wireless local
area networks are not the answer to all applications. Many factors
can impact the performance of a wireless network; therefore MiChoice
Technology, Inc. does not guarantee that a wireless local-area network
will function properly in every installation. Some installations
simply will not work with a wireless network, therefore the traditional
wired network is recommended. We strongly encourage the district/school
to consult with their network support staff or contractor to assist
them in making the best decision on whether or not wireless is a
suitable solution.
