Appendix A: FAQ
A.1 What and how to find my PC’s IP and MAC address?
IP address is the identifier for a computer or device on a TCP/IP network. Networks using the TCP/IP protocol
route messages based on the IP address of the destination. The format of an IP address is a 32-bit numeric
address written as four numbers separated by periods. Each number can be zero to 255. For example,
191.168.1.254 could be an IP address
The MAC (Media Access Control) address is your computer's unique hardware number. (On an Ethernet LAN,
it's the same as your Ethernet address.) When you're connected to the Internet from your computer (or host as
the Internet protocol thinks of it), a correspondence table relates your IP address to your computer's physical
(MAC) address on the LAN.
To find your PC’s IP and MAC address,
(1) Open the Command program in the Microsoft Windows.
(2) Type in “ipconfig /all”, then press the Enter button.
(3) Your PC’s IP address is the one entitled IP Address and your PC’s MAC address is the one entitled
Physical Address.
A.2 What is Wireless LAN?
A wireless LAN (WLAN) is a network that allows access to Internet without the need for any wired connections to
the user’s machine.
A.3 What are ISM bands?
ISM stands for Industrial, Scientific and Medical; radio frequency bands that the Federal Communications
Commission (FCC) authorized for wireless LANs. The ISM bands are located at 915 +/-13 MHz, 2450 +/-50 MHz
and 5800 +/-75 MHz.
A.4 How does wireless networking work?
The 802.11 standard define two modes: infrastructure mode and ad hoc mode. In infrastructure mode, the
wireless network consists of at least one access point connected to the wired network infrastructure and a set of
wireless end stations. This configuration is called a Basic Service Set (BSS). An Extended Service Set (ESS) is
a set of two or more BSSs forming a single sub-network. Since most corporate WLANs require access to the
wired LAN for services (file servers, printers, Internet links) they will operate in infrastructure mode.
