4 Network Configuration

Infrastructure Wireless LAN for Roaming Wireless PCs

The Basic Service Set (BSS) defines the communications domain for each access point and its associated wireless clients. The BSS ID is a 48-bit binary number based on the access point’s wireless MAC address, and is set automatically and transparently as clients associate with the access point. The BSS ID is used in frames sent between the access point and its clients to identify traffic in the service area.

The BSS ID is only set by the access point, never by its clients. The clients only need to set the Service Set Identifier (SSID) that identifies the service set provided by one or more access points. The SSID can be manually configured by the clients, can be detected in an access point’s beacon, or can be obtained by querying for the identity of the nearest access point. For clients that do not need to roam, set the SSID for the wireless card to that used by the access point to which you want to connect.

A wireless infrastructure can also support roaming for mobile workers. More than one access point can be configured to create an Extended Service Set (ESS). By placing the access points so that a continuous coverage area is created, wireless users within this ESS can roam freely. All wireless network cards and adapters and wireless access points within a specific ESS must be configured with the same SSID.

SMC Networks SMC2552W-G2-17 manual Infrastructure Wireless LAN for Roaming Wireless PCs

SMC2552W-G2-17, SMC2552W-G2 specifications

The SMC Networks SMC2552W-G2 and SMC2552W-G2-17 are advanced wireless access points designed for a range of networking environments, offering robust features suited to both home and business applications. These devices are known for their reliable performance, making them a popular choice for those seeking to enhance network connectivity and coverage.

One of the primary features of the SMC2552W-G2 is its dual-band capability, operating on both the 2.4 GHz and 5 GHz frequency bands. This versatility allows users to take advantage of the high capacity of the 5 GHz band, which is less congested and ideal for activities that require substantial bandwidth, such as streaming and online gaming. The 2.4 GHz band, on the other hand, provides better penetration through walls and is more suitable for basic browsing and mobile device connectivity.

Another significant characteristic is the device's support for the 802.11n Wi-Fi standard, which enables data rates of up to 300 Mbps. This standard ensures a fast and stable wireless connection, facilitating a seamless online experience for multiple devices simultaneously. The integration of MIMO (Multiple Input Multiple Output) technology further enhances the performance, allowing for multiple data streams to be transmitted and received, significantly increasing throughput and range.

The SMC2552W-G2 series also boasts advanced security features, including WPA/WPA2 encryption and support for 802.1X authentication. These security protocols provide robust protection against unauthorized access and ensure that data transmitted over the network remains secure.

In terms of management, these access points offer both web-based and SNMP (Simple Network Management Protocol) interfaces, enabling users to easily configure and monitor the network settings. This user-friendly interface simplifies the process of overseeing network performance and troubleshooting issues when they arise.

The SMC2552W-G2 and SMC2552W-G2-17 are designed for easy installation, whether as stand-alone units or as part of a larger network. Their compact design allows for flexible mounting options, making them suitable for various environments.

In summary, the SMC Networks SMC2552W-G2 and SMC2552W-G2-17 provide an excellent combination of speed, security, and ease of management, making them ideal solutions for enhancing wireless connectivity in both home and office settings. Their dual-band functionality, compliance with the latest Wi-Fi standards, and comprehensive security measures ensure a reliable and efficient networking experience.
