Ad Hoc Mode (Peer-to-Peer Workgroup)

In an ad hoc network, computers are brought together as needed; thus, there is no structure or fixed points to the network - each node can generally communicate with any other node. There is no Access Point involved in this configuration. This mode enables you to quickly set up a small wireless workgroup and allows workgroup members to exchange data or share printers as supported by Microsoft networking in the various Windows operating systems. Some vendors also refer to ad hoc networking as peer-to-peer group networking.

In this configuration, network packets are directly sent and received by the intended transmitting and receiving stations. As long as the stations are within range of one another, this is the easiest and least expensive way to set up a wireless network.

Network Name: Extended Service Set Identification (ESSID)

The Extended Service Set Identification (ESSID) is one of two types of Service Set Identification (SSID). In an ad hoc wireless network with no access points, the Basic Service Set Identification (BSSID) is used. In an infrastructure wireless network that includes an access point, the ESSID is used, but may still be referred to as SSID.

An SSID is a thirty-two character (maximum) alphanumeric key identifying the name of the wireless local area network. Some vendors refer to the SSID as network name. For the wireless devices in a network to communicate with each other, all devices must be configured with the same SSID.

The ESSID is usually broadcast in the air from an access point. The wireless station sometimes can be configured with the ESSID ANY. This means the wireless station will try to associate with whichever access point has the stronger radio frequency (RF) signal, providing that both the access point and wireless station use Open System authentication.

Authentication and WEP Data Encryption

The absence of a physical connection between nodes makes the wireless links vulnerable to eavesdropping and information theft. To provide a certain level of security, the IEEE 802.11 standard has defined these two types of authentication methods:

•Open System. With Open System authentication, a wireless computer can join any network and receive any messages that are not encrypted.

WG102 specifications

The NETGEAR WG102 is a robust and versatile wireless access point designed to enhance network connectivity in a variety of environments, from small businesses to larger enterprise settings. This device is well-regarded for its ease of use, reliable performance, and a feature set that caters to both basic and advanced networking needs.

One of the key features of the WG102 is its support for the IEEE 802.11g standard, which provides data rates of up to 54 Mbps. This makes it suitable for high-speed internet access and seamless data transfer for users connected to the network. Additionally, the WG102 is backward compatible with the 802.11b devices, ensuring that existing hardware can be integrated into the network without issues, thereby protecting investment in older technology.

The WG102 also excels in its deployment flexibility. With Power over Ethernet (PoE) support, installation becomes significantly easier, as the access point can receive power through the Ethernet cable, eliminating the need for additional power outlets. This feature is particularly advantageous in locations where power supply access is limited or where aesthetic considerations are key.

Security is a vital aspect of any network, and the WG102 does not disappoint. It supports Wi-Fi Protected Access (WPA and WPA2) for secure wireless communications, ensuring that user data is encrypted and protected from potential threats. The device also features WEP encryption, allowing users to implement various security measures based on their specific needs.

The WG102's management capabilities include a web-based interface, enabling administrators to configure settings easily and monitor network performance.
