Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point

Table B-2:	802.11b/g Radio Frequency Channels

Channel	Center Frequency	Frequency Spread

4	2427 MHz	2414.5 MHz - 2439.5 MHz

5	2432 MHz	2419.5 MHz - 2444.5 MHz

6	2437 MHz	2424.5 MHz - 2449.5 MHz

7	2442 MHz	2429.5 MHz - 2454.5 MHz

8	2447 MHz	2434.5 MHz - 2459.5 MHz

9	2452 MHz	2439.5 MHz - 2464.5 MHz

10	2457 MHz	2444.5 MHz - 2469.5 MHz

11	2462 MHz	2449.5 MHz - 2474.5 MHz

12	2467 MHz	2454.5 MHz - 2479.5 MHz

13	2472 MHz	2459.5 MHz - 2484.5 MHz

Note: The available channels supported by the wireless products in various countries are different. For example, Channels 1 to 11 are supported in the U.S. and Canada, and Channels 1 to 13 are supported in Europe and Australia.

The preferred channel separation between the channels in neighboring wireless networks is 25 MHz (5 channels). This means that you can apply up to three different channels within your wireless network. There are only 11 usable wireless channels in the United States. It is recommended that you start using channel 1 and grow to use channel 6, and 11 when necessary, as these three channels do not overlap.

Wi-Fi Protected Access (WPA) is a specification of standards-based, interoperable security enhancements that increase the level of data protection and access control for existing and future wireless LAN systems.

The IEEE introduced the WEP as an optional security measure to secure 802.11b (Wi-Fi) WLANs, but inherent weaknesses in the standard soon became obvious. In response to this situation, the Wi-Fi Alliance announced a new security architecture in October 2002 that remedies the shortcomings of WEP. This standard, formerly known as Safe Secure Network (SSN), is designed to work with existing 802.11 products and offers forward compatibility with 802.11i, the new wireless security architecture being defined in the IEEE.

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. The device supports VLAN tagging, which can help in segmenting network traffic for better performance and security. The ability to manage multiple access points through a single interface also streamlines network management.

In terms of physical characteristics, the NETGEAR WG102 is designed for durability and reliability. Its compact form factor allows for discreet installation, whether mounted on a ceiling, wall, or placed on surfaces.

Overall, the NETGEAR WG102 is a dependable access point that offers a combination of speed, security, and ease of management, making it an excellent choice for those looking to enhance their wireless networking capabilities.
