WLAN Installation in Windows

For those uses newer Windows XP or Windows 2000, it would be easier to find the needed WLAN card driver. However, for older Windows versions it may require a little bit more effort.

In this chapter, an example of WLAN driver installation process in Microsoft Windows 98 will be shown. I am using an old Samsung MagicLAN SWL-2000P at my home installation. The newer models may be much easier to install.

Please note that after the driver installation, we need to configure the TCP/IP network settings. It is treated as normal LAN connection. The network configuration can be performed through normal way, i.e

In this chapter, some of the Radio Frequency (RF) terminologies and concepts will be described.

Frequency

Frequency is the number of complete cycles per second in alternating current direction. The standard unit of frequency is the hertz, abbreviated Hz. One (1) Hz is the frequency at which the current complete one cycles. Depending on the number of cycles, we are looking at

Kilohertz (kHz) thousand of cycles

Megahertz (MHz) million of cycles

Gigahertz (GHz) billion of cycles

Terahertz (THz) zillion of cycles

An Access Point at the Internet Service Provider (ISP) is normally located high on top of the tower. Henry Syarifuddin’s team installs this particular setting.

A closed up picture shows the SmartBridges (http://www.smartbridges.com) Access Point install on top of the tower. The coaxial cable connecting the Access Point to the Antenna is kept short to minimize the loss. An omnidirectional antenna is used. The bottom side of the antenna is visible in the close up.

WiFi (Wireless Fidelity) is basically a generic term for wireless LAN equipments, also known as WLAN. It normally confirms the standard IEEE 802.11 family and, thus, supported by many vendors.

Why WiFi based Wireless Internet Infrastructure? There are few simple answers, i.e.,

• Wireless for bypassing the need of costly & slow telephone line for accessing the Internet.


• Wireless is easy to deploy. It requires a much lower cost in the long run, rather than rely on Telco’s infrastructure.


• WiFi is basically a Wireless LAN and, thus, it runs at higher speed 1-11Mbps if the standard IEEE 802.11b is used.
