1. Introduction 1.1 The WLAN 802.11g 802.11g is a 54Mbps wireless networking standard that's almost five times faster than the widely deployed 802.11b products found in homes, businesses, and public wireless hotspots. Because both 802.11b and 802.11g share the same 2.4GHz radio band, 802.11g devices can also work with existing 11Mbps 802.11b equipment.
2. Planning Your Wireless Network 2.1 WLAN A wireless local area network (WLAN) is exactly like a regular local area network (LAN), except that each computer in the WLAN uses a wireless device to connect to the network. Computers in a WLAN share the same frequency channel and SSID, which is an identification name for wireless devices. 2.2 Ad-Hoc and Infrastructure Unlike wired networks, wireless networks have two different modes: Ad-Hoc and Infrastructure.
Figure 2-2.) Ad-Hoc mode allows computers equipped with wireless transmitters and receivers to communicate directly with each other, eliminating the need for an access point. The drawback of this mode is that, in Ad- Hoc mode, wireless-equipped computers are not able to communicate with computers on a wired network.
3. Software Installation and Uninstallation Note! The Installation Section in this Manual describes the first-time installation for Windows. To re-install the driver, please first uninstall the previously installed driver. See Chapter “3.4 Uninstallation” in this Manual. 3.1 Setup Wizard Installation Follow the steps below to complete the driver/utility installation: 1.

Appendix A: Glossary 802.11b – One of the IEEE standards of wireless networking hardware. Products that adhere to a specific IEEE standard will work with each other, even if they are manufactured by different companies. The 802.11b standard specifies a maximum data transfer rate of 11Mbps, an operating frequency of 2.4GHz, and WEP encryption for security. 802.11b networks are also referred to as Wi-Fi networks. 802.11g – Refers to the proposed extension of the IEEE 802.
DHCP uses the concept of a “lease” or amount of time that a given IP address will be valid for a computer. The lease time can vary depending on how long a user is likely to require the Internet connection at a particular location. It’s especially useful in education and other environments where users change frequently. Using very short lease, DHCP can dynamically reconfigure networks in which there are more computers than there are available IP address.
international standards. The organization publishes a number of journals, has many local chapters, and several large societies in special areas, such as the IEEE Computer Society. Infrastructure Network – An Infrastructure network is a group of computers or other devices, each with a wireless adapter, connected as an 802.11 wireless LAN. In infrastructure mode, the wireless devices communicate with each other and to a wired network by first going through an access point.
unique hardware number. mIRC – mIRC runs under Windows and provides a graphical interface for logging onto IRC servers and listing, joining and leaving channels. Network Mask – also known as the “Subnet Mask”. OFDM – Developed for wireless applications, Orthogonal Frequency Division Multiplexing (OFDM) technology offers superior performance-increased data rates and more reliable transmissions- than previous technologies, such as DSSS.
or subnets. The mask is a binary pattern that is matched up with the IP address to turn part of the host ID address field into a field for subnets. TCP (Transmission Control Protocol) - A method (protocol) used along with the IP (Internet Protocol) to send data in the form of message units (data gram) between network devices over a LAN or WAN.
