About Wireless LANs

This Appendix provides some background information about using Wireless LANs (WLANs).

Modes

Wireless LANs can work in either of two (2) modes:

Ad-hoc

Infrastructure

Ad-hoc Mode

Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless Stations (e.g. notebook PCs with wireless cards) communicate directly with each other.

Infrastructure Mode

In Infrastructure Mode, one or more Access Points are used to connect Wireless Stations (e.g. Notebook PCs with wireless cards) to a wired (Ethernet) LAN. The Wireless Stations can then access all LAN resources.

Access Points can only function in "Infrastructure" mode, and can communicate only with Wireless Stations which are set to "Infrastructure" mode.

BSS/ESS

BSS

A group of Wireless Stations and a single Access Point, all using the same ID (SSID), form a Basic Service Set (BSS).

Using the same SSID is essential. Devices with different SSIDs are unable to communicate with each other.

ESS

A group of Wireless Stations, and multiple Access Points, all using the same ID (ESSID), form an Extended Service Set (ESS).

Different Access Points within an ESS can use different Channels. In fact, to reduce interference, it is recommended that adjacent Access Points SHOULD use different channels.

As Wireless Stations are physically moved through the area covered by an ESS, they will automatically change to the Access Point which has the least interference or best performance. This capability is called Roaming. (Access Points do not have or require Roaming capabilities.)

HWR54G specifications

Hawking Technology has made a significant impact in the networking industry with their HWR54G wireless router, a device designed to cater to both home and small office requirements. This versatile router combines advanced technology with user-friendly features, making it suitable for a wide range of users.

One of the standout features of the HWR54G is its high-speed wireless connectivity, which adheres to the 802.11g standard. This technology enables users to experience data transfer rates of up to 54 Mbps, allowing for seamless streaming, gaming, and browsing. Furthermore, the router is backward compatible with the older 802.11b devices, ensuring that a broader range of devices can still connect effectively.

The HWR54G also incorporates robust security features that enhance network protection. With support for WEP, WPA, and WPA2 encryption standards, users can configure their networks according to their specific security requirements. This flexibility is crucial for protecting sensitive data from unauthorized access, making the router a trusted choice for users who prioritize their network’s security.

Another notable characteristic of the HWR54G is its ease of installation and setup. The router comes with user-friendly documentation and an intuitive web interface, which simplifies the entire process for users, even those with limited technical experience. This is particularly important for home users and small businesses looking to establish a reliable network quickly.

Additionally, the HWR54G features multiple Ethernet ports, allowing for wired connections to other devices such as printers and desktop computers. This combination of wired and wireless options provides users with the flexibility to connect their devices according to their specific needs.

The range of the HWR54G is also commendable, with its ability to cover moderate-sized areas effectively. This makes it an excellent choice for small to medium-sized homes or office environments where consistent connectivity is crucial.

In summary, the Hawking Technology HWR54G wireless router distinguishes itself with its high-speed wireless performance, strong security protocols, user-friendly setup, and versatile connectivity options. As technology continues to evolve, this router remains a reliable choice for users seeking an efficient and effective networking solution.
