6. GLOSSARY The following glossary is for your reference, and is not directly related to the installation

of your Access Point.

- Wireless Access Point (AP) – Any entity that has station functionality provides access to the distribution services via the wireless medium (WM) for associated stations.

- Ad-Hoc – A network is composed solely of stations within mutual communication range of each other via the wireless medium (WM). An ad hoc network is typically created in a spontaneous manner. The principal distinguishing characteristic of an ad hoc network is its limited temporal and spatial extent. These limitations allow the act of creating and dissolving the ad hoc network to be sufficiently straightforward and convenient so as to be achievable by non-technical users of the network facilities; i.e., no specialized technical skills are required and little or no investment of time or additional resources is required beyond the stations that are to participate in the ad hoc network. Ad hoc is often used as a slang term to refer to an independent basic service set (IBSS).

- BSS (Basic Service Set) – An AP is associated with several wireless stations.

- ESS (Extended Service Set) – More than one BSS can be configured as an Extended

Service Set. An ESS is basically a roaming domain.

- Ethernet – A popular local area network, originally developed by Xerox Corp., accepts transmissions from computers and terminals. Ethernet operates on 10 Mbps baseband transmission over shielded coaxial cable or over shielded twisted pair telephone wire.

- Fragmentation Threshold Value – Indicates how much of the network resources is devoted to recovering packet errors. The value should remain at its default setting of 2,436. If you experience high packet error rates, you can decrease this value but it will likely decrease overall network performance. Only minor modifications of this value are recommended.

- Infrastructure – The infrastructure includes the distribution system medium (DSM), AP, and portal entities. It is also the logical location of distribution and integration service functions of an extended service set (ESS). An infrastructure contains one or more APs and zero or more portals in addition to the distribution system (DS).

- IEEE – Institute of Electrical and Electronic Engineering

- LAN – Local Area Network

- Open System – Is when the sender and the recipient do not share a secret key.

Each party generates its own key -pair and asks the receiver to accept the (usually randomly) generated key. Once accepted, this key is used for a short time only; then a new key is generated and agreed upon.

- Roaming – A function allows one to travel with a mobile end system (wireless LAN mobile station, for example) through the territory of a domain (an ESS, for example) while continuously connecting to the infrastructure.

- RSS – Receive Signal Strength

Page 37

- RTS/CTS Threshold – Should remain at its default setting of 2,346. A preamble is a signal used to synchronize the transmission timing between two or more systems. A series of transmission pulses is sent before the data to indicate that “someone is about transmit data.” This ensures that systems receiving the information correctly when the data transmission starts.

- Shared Key – Is when both the sender and recipient share a secret key. Both units

use this key for an extended length of time, sometimes indefinitely. Any eavesdropper that discovers the key may decipher all packets until the key is changed.

- SOHO – Small Office Home Office

- SSID – Is the unique name shared among all points in a wireless network. The

SSID must be identical for all points in the network. It is case sensitive and must not exceed 32 characters.

- Wired Equivalent Privacy (WEP) – The optional cryptographic confidentiality algorithm specified by IEEE 802.11 provides data confidentiality that is subjectively equivalent to the confidentiality of a wired local area network medium that does not employ cryptographic techniques to enhance privacy.

8. WIRELESS LAN SYSTEM The contents in this section, which are not directly related to the installation of your

Access Point, are for you to have better understanding of a Wireless LAN system.

8.1 802.11 Ad-Hoc Configuration An 802.11 Ad-Hoc wireless LAN is a group of computers, each equipped with one

wireless LAN card, connected as an independent wireless LAN. Computers in a specific

802.11 Ad -Hoc wireless LAN must be configured at the same radio channel and BSS ID.

802.11 Ad -Hoc wireless LAN is applicable to a departmental scale for a branch or SOHO operation.

Figure 1. 802.11 Ad-Hoc Configuration

8.2 Infrastructure Configuration An integrated wireless and wired LAN is called an infrastructure configuration. A group

of wireless LAN cards and an Access Point (AP) is called a Basic Service Set (BSS). Each wireless LAN card in this BSS can be linked to any computer in the wired LAN infrastructure via the AP.

Infrastructure configuration not only extends the accessibility of a wireless LAN card to the wired LAN, but also doubles the effective wireless transmission range between two wireless LAN cards.

BSS ID is, in essential, the ID of each independent wireless LAN card. All wireless LAN cards configured without roaming options in this independent BSS must be configured with BSS ID of that AP. You may need to check BSS ID of your AP by using its vendor supplied program.

Page 43

Infrastructure configuration is applicable to enterprise scale for wireless access to central database, or wireless application for mobile workers.

Two APs can be used as a point-to-point link between two LANs. LAN interconnection is applicable to a wireless backbone between buildings.

Figure 2. Infrastructure Configuration

The infrastructure configuration supports roaming capability for mobile workers. More than one BSS can be jointly configured as an Extended Service Set (ESS). On account of a continuous connection to the network, users within this ESS can roam freely. All wireless LAN cards and APs within one ESS must be configured with the same ESS ID.

Before setting up an ESS for roaming, it would be helpful to achieve good performance by choosing a feasible radio channel and right places for APs.
