Overview


WHAT THIS PRODUCT DOES
TP-LINK TL-WN781N is designed to provide a complete end-to-end wireless performance from the server or server backbone to the switch infrastructure and down through to the desktop with the PCI Express connector. TL-WN781N Wireless Lite N PCI Express(x1) Adapter provides a wider compatibility, fitting with any standard PCI Express slot, x1, x2, x8, or x16. Compared with standard PCI network cards, it offers increased bandwidth, reliability and more functionality, allowing you to enjoy a fast and advanced connection, such as downloading, making internet call and video streaming.

Wireless N ---- Speed & Range
Complying with the IEEE 802.11n standard, TL-WN781N can easily establish a wireless network and get up to 9X the speed and 4X the range of conventional 11g products. Compared with legacy 54M products, TL-WN781N delivers performance enhancements, allowing you to have a more joyful surfing experience, including sharing files, watching streaming media.

WPA / WPA2 Encryptions ---- Advanced Security
As for the security of WI-FI connection, WEP encryption has been no longer the strongest and safest guards for outside intrusions. TL-WN781N provides WPA/WPA2 encryptions that are created by the WI-FI Alliance industry group, preventing the wireless network from outside threats.

Quick Setup Security
Compatible with WI-FI Protected Setup™ (WPS), TL-WN781N features Quick Security Setup (QSS) function, which is ideal for creating a WPA encrypted connection to prevent outside intrusion, and meanwhile maximize the management resources. Not only is this faster than normal security setups but more convenient in that you don’t need to remember a password!

Detachable Antenna
TL-WN781N offers external antenna that can be rotated and adjusted in different directions to fit various operation environments, and can bring better performance than the internal antenna. For even more demanding applications, the antenna can be replaced with diverse antennas to show even greater flexibility and wider wireless coverage.

Specification

Technical Description: TP-Link TL-WN781ND network card Internal WLAN 150 Mbit/s
Design
Operating modes:
Infrastructure mode
Chipset:Set of electronic components in an integrated circuit that manages the data flow between the processor, memory and peripherals. It is usually found in the motherboard of a computer. Chipsets are usually designed to work with a specific family of microprocessors. Because it controls communications between the processor and external devices, the chipset plays a crucial role in determining system performance.
Atheros
Antenna gain level (max):Antenna gain is the measurement of an antenna's ability to amplify the incoming microwave signals in a particular direction, compared with the sensitivity of an isotropic antenna in any direction, or a dipole antenna in the equatorial direction.

Network
Security algorithms:Security algorithms are used to provide authentication, cipher key generation, integrity and radio link privacy to users on mobile networks. The security algorithms supported are the ones that can be used with this product.
128-bit WEP, 64-bit WEP, WPA-PSK, WPA2-PSK
Modulation:Modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal (High Frequency Signal), with a modulating signal which typically contains information to be transmitted. The aim of digital modulation is to transfer a digital bit stream over an analog bandpass channel, for example over the public switched telephone network (where a bandpass filter limits the frequency range to between 300 and 3400 Hz), or over a limited radio frequency band. The aim of analog modulation is to transfer an analog baseband (or lowpass) signal, for example an audio signal or TV signal, over an analog bandpass channel at a different frequency, for example over a limited radio frequency band or a cable TV network channel.
16-QAM, 64-QAM, CCK, DBPSK, DQPSK, OFDM
