system can be set with authenticated security
so that only the authorized tenants can access
the network. Buffalo’s wireless solution can
be used as an optional fee-based service.
6.3 Schools
Sometimes it is necessary for students to
have personal Internet connections for
schoolwork. Wireless LANs make the
network connection flexible within a school
campus. The broadband availability area can
be expanded using Buffalo’s wireless building-
to-building solution. This solution uses an
outdoor antenna for each building instead of
installing CAT5 cable between buildings.
Accessing the network and Internet anywhere
and anytime on campus is a part of Buffalo’s
total support of educational technology.
6.4 Hospitals
Medical test results and diagnostics for each
patient in the hospital database should be
updated in real time. The wireless solution
used to connect to the hospital network can
be crucial for saving patients’ lives. For
example, the newest diagnostic data is
updated to a hand-held wireless device at the
patient’s bedside so that the appropriate
prescription is prepared on time. Similarly,
surgical data can be transmitted to a central
database in real time for crosschecking the
operating procedures. In these cases, there is
no need for network cables. The security of
wireless communication is well enhanced by
MAC address filtering (port security) so that
only authorized personnel can access the
hospital network.
6.5 Factories
In this scenario, a wireless LAN is seen in a
manufacturing line in a factory. A variety of
control machines and robots are connected
to the central server and operated wirelessly.
Using Buffalo’s wireless networking system,
the manufacturing data is sent to the factory
server immediately so that the center can
efficiently respond to decisions and com-
