Wireless Product Equipment - Network Routers, Access Points, TV, Adapters and More
This is a great topic that shows us how the technology is to be used
Illustrated above is the Linksys WRT54G (compare prices). This is a popular wireless router product based on the 802.11g Wi-Fi network standard. Wireless routers are small box-like devices generally less than 12 inches (0.3 m) in length, with LED lights on the front and with connection ports on the sides or back. Some wireless routers like the WRT54G feature external antennas that protrude from the top of the device; others contain built-in antennas.
Wireless router products differ in the network protocols they support (802.11g, 802.11a, 802.11b or a combination), in the number of wired device connections they support, in the security options they support, and in many other smaller ways. Generally only one wireless router is required to network an entire household.
In home networking, wireless access points can be used to extend an existing home network based on a wired broadband router. The access point connects to the broadband router, allowing wireless clients to join the home network without needing to rewire or re-configure the Ethernet connections.
As illustrated by the Linksys WAP54G (compare prices) shown above, wireless access points appear physically similar to wireless routers. Wireless routers actually contain a wireless access point as part of their overall package. Like wireless routers, access points are available with support for 802.11a, 802.11b, 802.11g or combinations.
Some notebook computers are now manufactured with built-in wireless networking. Small chips inside the computer provide the equivalent functions of a network adapter. These computers obviously do not require separate installation of a separate wireless network adapter.
- Allows printers to be conveniently located anywhere within wireless network range, not tied to the location of computers
- Does not require a computer be always turned on in order to print
- Does not require a computer to manage all print jobs, that can bog down its performance
- Allows administrators to change computer names and other settings without having to re-configure the network printing settings.
Most print server products include setup software on a CD-ROM that must be installed on one computer to complete the initial configuration of the device. As with network adapters, wireless print servers must be configured with the correct network name (SSID) and encryption settings. Additionally, a wireless print server requires client software be installed on each computer needing to use a printer. Print servers are very compact devices that include a built-in wireless antenna and LED lights to indicate status. The Linksys WPS54G (compare prices) 802.11g USB wireless print server is shown as one example.
Wireless Internet video cameras work by serving up data streams to any computer that connects to them. Cameras like the one above contain a built in Web server. Computers connect to the camera using either a standard Web browser or through a special client user interface provided on CD-ROM with the product. With proper security information, video streams from these cameras can also be viewed across the Internet from authorized computers.
Internet video cameras can be connected to a wireless router using either an Ethernet cable or via Wi-Fi. These products include setup software on a CD-ROM that must be installed on one computer to complete initial Wi-Fi configuration of the device.
Features that distinguish different wireless Internet video cameras from each other include:
- resolution of the captured video images (for example, 320x240 pixel, 640x480 pixel, and other image sizes)
- motion sensors, and the ability to send email alerts when new activity is detected and captured
- ability to time stamp images
- built-in microphones and/or jacks for external microphones, for audio support
- types of WiFi security supported, such as WEP or WAP
A wireless range extender connects via Wi-Fi to a router or access point. However, due to the nature of this technology, most wireless range extenders work only with a limited set of other equipment. Check the manufacturer's specifications carefully for compatibility information.
Wireless VGA to TV converter
This device uses the 2.4Ghz frequency, which can also be used by Wireless internet, cordless phones, remote controlled electronics and other wireless devices. To help you avoid interference, you can select from 4 channels on the SW-28760, but in some cases there may not be enough available bandwidth to get a clear signal. In those cases we recommend looking at our wide range of wired PC to TV converters like the SW-23000.
