Chapter 2: Planning Your Wireless Network

Introduction

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 and other devices, such as peripherals, in a WLAN share the same frequency channel and SSID, which is an identification name for wireless devices.

Ad-Hoc and Infrastructure Modes

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 accessed 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 an access point, which serves as the main point of communications in a wireless network. (A wireless router can also be used because a wireless router incorporates the capabilities of an access point.) Access points transmit data to PCs equipped with wireless network cards, which can roam within a certain radial range of the access point. Multiple access points can be arranged to work in succession to extend the roaming range, and can be set up to communicate with your Ethernet (wired) 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 an 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 Internet Video Camera is compatible with all 802.11b and 802.11g routers, such as model numbers BEFW11S4 and WRT54G, as well as access points, including model numbers WAP11 and WAP54G. The

LAN (Local Area Network): the computers and networking products that make up the network in your home or office.

WLAN (Wireless Local Area Network): A group of computers and associated devices that communicate with each other wirelessly.

Infrastructure: configuration in which a wireless network 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.

WVC54G-UK specifications

The Linksys WVC54G-UK is an advanced wireless network camera designed for flexibility and convenience in surveillance applications. It offers a range of features that cater to both home and business users seeking to maintain security through remote monitoring.

At the heart of the WVC54G-UK is its ability to deliver high-quality video streaming. The camera supports a resolution of up to 640x480 pixels, which is adequate for monitoring indoor spaces. Equipped with a 1/4 inch CMOS sensor, it provides decent image quality in varied lighting conditions. The infrared (IR) capability is a vital feature of this camera, enabling it to capture clear images even in low-light environments, making it a compelling choice for nighttime surveillance.

Another major strength of the WVC54G-UK is its wireless connectivity. It adheres to the IEEE 802.11g standards, offering data rates up to 54 Mbps. This facilitates easy installation without the need to run cables throughout your space. Users can set up the camera anywhere within the wireless range of their router, enhancing installation flexibility. Additionally, the camera supports WEP and WPA security protocols, ensuring that the video feed is secure from unauthorized access.

The integrated web server allows for remote access via a standard web browser, giving users the ability to monitor their premises from anywhere with an internet connection. This is particularly useful for business owners who need to keep an eye on operations or parents wishing to ensure the safety of their children at home. Notably, the camera supports multiple video formats, including MJPEG and MPEG, ensuring compatibility with various web streaming technologies.

For users who prefer a more hands-on approach, the WVC54G-UK includes built-in motion detection capabilities. Users can set motion-triggered alerts, allowing the camera to send notifications when unusual movement is detected. This feature not only enhances security but also conserves storage space by only recording significant activity.

The WVC54G-UK is designed for ease of use, with a straightforward setup process thanks to its user-friendly configuration interface. It also supports various operating systems, making it a versatile addition to any existing surveillance system. Overall, the Linksys WVC54G-UK stands out as a reliable choice for anyone looking to bolster their security with a wireless camera solution featuring robust functionality, flexibility, and quality performance.
