Introduction of wireless network card and the purchase of wireless network card

Wireless network card is the equipment of the terminal wireless networks, wireless LAN wireless coverage under the wireless network for Internet access to the use of radio terminals. Specifically, the wireless card is a device that allows your computer to use wireless to access the Internet, but with wireless network card also need a can connect Wi-Fi, if in the home or the location of the wireless router or wireless AP coverage, you can wirelessly connect wireless network to the Internet.

Depending on the interface, the wireless card can be divided into several categories:

One is a desktop-specific PCI interface wireless network card, a laptop dedicated PCMCIA interface card, a USB wireless network card, which is either a desktop user or a notebook user, as long as the driver installed, can be used. In the selection should be noted that only the use of USB2.0 interface wireless network card to meet the requirements of 802.11g or 802.11g+. In addition, there are a wide range of applications in the notebook computer MINI-PCI wireless network card. MINI-PCI is a built-in wireless network card, which is used by both the Centrino model and the non-Centrino wireless network card standard models. The advantage is that it eliminates the need for a PC card or USB slot and eliminates the hassle of carrying a PC Card or USB card at any time. At present, these kinds of wireless card in the price gap is not small, in performance/function is also similar, on demand and choose.

Excellent wireless performance

Tp-link wireless network card using 11N wireless technology, wireless transmission rate of up to 150Mbps. Compared with the traditional 54Mbps 11G products, has a higher wireless bandwidth, so that the local area network data transmission more efficient, can effectively reduce network latency, so that voice video, online games, on-line VOD more fluent.

Tp-link Wireless network card also uses CCA (Clear Channel Assessment) Air channel detection technology, detected in the vicinity of wireless signal interference, can automatically adjust the bandwidth mode, avoid channel interference, so that wireless signal more stable. When the interference disappears, it can automatically bundle the idle channel, and make full use of the channel bundle advantage to enhance the wireless performance.

External high gain antenna

Tp-link Wireless network card external 4dBi omni Antenna, in the open environment can make wireless signal transmission distance farther, in many barrier or multiple interference complex wireless environment, can provide better wireless penetration capability and signal stability.

Full range of security guarantees

The Tp-link wireless network card supports WPA-PSK/WPA2-PSK, WPA/WPA2 security, and WEP encryption to protect wireless networks from intrusion and misappropriation.
