4. Can data be intercepted while transmitting through the air?
WLAN features two-fold protection in security. On the hardware side,
as with Direct Sequence Spread Spectrum technology, it has the inherent
scrambling security feature. On the software side, the WLAN series
offers the encryption function (WEP) to enhance security and access
control.
5. What is WEP?
WEP stands for Wired Equivalent Privacy, a data privacy mechanism
based on a 64(40)-bit shared key algorithm.
6. What is a MAC Address?
The Media Access Control (MAC) address is a unique number assigned
by the manufacturer to any Ethernet networking device, such as a
network adapter, that allows the network to identify it at the hardware
level. For all practical purposes, this number is usually permanent.
Unlike IP addresses which can change every time a computer logs on to
the network, the MAC address of a device stays the same, making it a
valuable identifier for the network.
