Wireless-G Exterior Access Point • Fragmentation • Power Management What IEEE 802.11g features are supported? The product supports the following IEEE 802.11g functions: • CSMA/CA plus Acknowledge protocol • OFDM protocol • Multi-Channel Roaming • Automatic Rate Selection • RTS/CTS feature • Fragmentation • Power Management What is Ad-hoc? An Ad-hoc wireless LAN is a group of computers, each with a WLAN adapter, connected as an independent wireless LAN. An Ad-hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation. What is Infrastructure? An integrated wireless and wired LAN is called an Infrastructure configuration. Infrastructure is applicable to enterprise scale for wireless access to a central database, or wireless application for mobile workers. What is roaming? Roaming is the ability of a portable computer user to communicate continuously while moving freely throughout an area greater than that covered by a single Access Point. Before using the roaming function, the workstation must make sure that it is set to the same channel number as the Access Point of the dedicated coverage area. To achieve true seamless connectivity, the wireless LAN must incorporate a number of different functions. Each node and Access Point, for example, must always acknowledge receipt of each message. Each node must maintain contact with the wireless network even when not actually transmitting data. Achieving these functions simultaneously requires a dynamic RF networking technology that links Access Points and nodes. In such a system, the user's end node undertakes a search for the best possible access to the system. First, it evaluates such factors as signal strength and quality, as well as the message load currently being carried by each Access Point and the distance of each Access Point to the wired backbone. Based on that information, the node next selects the right Access Point and registers its address. Communications between end node and host computer can then be transmitted up and down the backbone. As the user moves on, the end node's RF transmitter regularly checks the system to determine whether it is in touch with the original Access Point or whether it should seek a new one.

What is Ad-hoc?

An Ad-hoc wireless LAN is a group of computers, each with a WLAN adapter, connected as an independent

wireless LAN. An Ad-hoc wireless LAN is applicable at a departmental scale for a branch or SOHO

operation.

What is Infrastructure?

An integrated wireless and wired LAN is called an Infrastructure configuration. Infrastructure is applicable

to enterprise scale for wireless access to a central database, or wireless application for mobile workers.

What is roaming?

Roaming is the ability of a portable computer user to communicate continuously while moving freely

throughout an area greater than that covered by a single Access Point. Before using the roaming function, the

workstation must make sure that it is set to the same channel number as the Access Point of the dedicated

coverage area.

To achieve true seamless connectivity, the wireless LAN must incorporate a number of different functions.

Each node and Access Point, for example, must always acknowledge receipt of each message. Each node

must maintain contact with the wireless network even when not actually transmitting data. Achieving these

functions simultaneously requires a dynamic RF networking technology that links Access Points and nodes.

In such a system, the user’s end node undertakes a search for the best possible access to the system. First, it

evaluates such factors as signal strength and quality, as well as the message load currently being carried by

each Access Point and the distance of each Access Point to the wired backbone. Based on that information,

the node next selects the right Access Point and registers its address. Communications between end node and

host computer can then be transmitted up and down the backbone.
