Wireless-G Broadband Router

Chapter 2: Planning Your Wireless Network

Network Topology

A wireless local area network (WLAN) is exactly like a regular local area network (LAN), except that each computer in the WLAN uses a wireless device to connect to the network. Computers in a WLAN share the same frequency channel and SSID, which is an identification name shared by the wireless devices belonging to the same wireless network.

ssid (service set identifier): your wireless network’s name.

Ad-Hoc versus Infrastructure Mode

Unlike wired networks, wireless networks have two different modes in which they may be set up: infrastructure and ad-hoc. An infrastructure configuration is a WLAN and wired LAN communicating to each other through an access point. An ad-hoc configuration is wireless-equipped computers communicating directly with each other. Choosing between these two modes depends on whether or not the wireless network needs to share data or peripherals with a wired network or not.

If the computers on the wireless network need to be accessible by a wired network or need to share a peripheral, such as a printer, with the wired network computers, the wireless network should be set up in Infrastructure mode. The basis of Infrastructure mode centers around a wireless router or an access point, such as the Wireless-G Broadband Router, which serves as the main point of communications in a wireless network. The Router transmits data to PCs equipped with wireless network adapters, which can roam within a certain radial range of the Router. You can arrange the Router and multiple access points to work in succession to extend the roaming range, and you can set up your wireless network to communicate with your Ethernet hardware as well.

If the wireless network is relatively small and needs to share resources only with the other computers on the wireless network, then the Ad-Hoc mode can be used. Ad-Hoc mode allows computers equipped with wireless transmitters and receivers to communicate directly with each other, eliminating the need for a wireless router or access point. The drawback of this mode is that in Ad-Hoc mode, wireless-equipped computers are not able to communicate with computers on a wired network. And, of course, communication between the wireless- equipped computers is limited by the distance and interference directly between them.

Network Layout

The Wireless-G Broadband Router has been specifically designed for use with both your 802.11b and 802.11g products. Now, products using these standards can communicate with each other.

infrastructure: a wireless network that is bridged to a wired network via an access point.

ad-hoc: a group of wireless devices communicating directly to each other (peer-to- peer) without the use of an access point.

WRK54G specifications

The Cisco Systems WRK54G is a versatile wireless router designed to meet the demands of home and small office networking. Renowned for its reliability, it offers a range of features that cater to both casual users and tech-savvy individuals.

At its core, the WRK54G is built on the IEEE 802.11g standard, which supports data transfer rates of up to 54 Mbps. This makes it suitable for various internet-based applications, including browsing, streaming, and online gaming. Additionally, it is backward compatible with the earlier 802.11b standard, ensuring that users with older devices can still enjoy connectivity.

One of the standout features of the WRK54G is its wireless connectivity, which allows users to connect multiple devices without the need for cumbersome cabling. This is especially beneficial in environments where mobility is essential. The router employs robust security protocols, including WEP, WPA, and WPA2, to safeguard the network from unauthorized access and ensure the integrity of data transmission.

In terms of hardware, the WRK54G is equipped with a built-in four-port Ethernet switch, enabling wired connections for devices that require stable and faster internet access, such as desktop computers and gaming consoles. This dual capability of wired and wireless networking makes it a flexible solution for diverse user needs.

Another noteworthy characteristic of the WRK54G is its support for Quality of Service (QoS) functionalities. QoS technology prioritizes bandwidth for specific applications, ensuring that essential services such as VoIP and video streaming receive the necessary resources for optimal performance. This feature is vital for users who rely on uninterrupted internet access for work or entertainment.

Additionally, the router features an intuitive web-based interface that simplifies setup and configuration. Users can easily manage their network settings, create a secure wireless environment, and monitor connected devices without requiring extensive technical knowledge.

In conclusion, the Cisco Systems WRK54G is a reliable and feature-rich wireless router that supports modern networking demands. With its solid performance, robust security measures, dual connectivity options, and user-friendly interface, it remains a practical choice for both home and small business users looking to establish a seamless network experience. Whether for streaming, gaming, or web browsing, the WRK54G provides a solid foundation for a comprehensive wireless networking solution.
