DWL-520+EOL EOS

2.4GHz Enhanced Performance Wireless LAN PCI Card

Tanımlama

Enhanced Speed Transmission
At 22 Megabits per second, the DWL-520+ delivers high data transfer rate within the industry standard. This speed is double the 11Mbps normally found among IEEE 802.11b 2.4GHz wireless LAN devices.

Industry-standard Interoperability
With both WiFi  certification compatibility and IEEE 802.11b wireless LAN industry standard compliance, the DWL-520+ adapter provides you with excellent network interoperability.

Network Security
Security is an issue when data is transmitted without the wires. In the air, transmitted data can be easily intercepted if not well protected by a security scheme. The DWL-520+ provides the necessary security, using the enhanced 64/128/256-bit industry-standard WEP (Wired Equivalent Privacy) encryption protocol. Data privacy mechanism is based on a shared key algorithm, as described in the wireless
LAN standard.

Easy Installation
With PCI plug-and-play installation, the DWL-520+ can be easily installed into a desktop PC to provide connectivity directly to another 802.11b wireless enabled device (ad-hoc mode) or through an 802.11b Access Point (infra-structure mode).

Detachable Antenna
The DWL-520+ is equipped with an SMA reverse detachable dipole antenna with an effective range of 100 meters indoors, or 400 meters outdoors. Where a longer range is required, you can easily remove this antenna and replace it with a higher Gain antenna.
