4 Steps to Choose a Mini PCI-E Bluetooth Wifi Card
The main difference between Wireless Network card and Network card is signal to receive and send data, if you can find Internet access port, but also can be achieved with Internet connections. Today, the wireless card is more product categories, and prices vary. For ordinary consumers, the purchase of your home wireless mini pci-e card when the purchase is sure to encounter all kinds of errors.
1 transmission rate is not the only criterion to measure the performance
Transfer rate here refers to the wireless network card in some of the data under the standard network protocol to send and receive capabilities, the rate depends on the support of the standards and the surrounding environment and other factors, the general product tagging is theoretical transfer rate, the actual transfer rate significantly lower than the theoretical transfer rate.
To measure the overall performance of a bluetooth Wifi Mini pci-e card, looking at transfer rates of an indicator is not enough, also need to note that the product interface types, transmission range, price brand, security, compatibility and other features.
In addition, the performance of a wireless network card to play will depend on the entire wireless LAN circumstances of each case, such as the use of a wireless LAN TP-LINK TL-WN610G 108Mbps in Super G wireless card, while the wireless router using the transfer rate of 54Mbps products, so in theory case, the wireless card would be adaptive, "deceleration" up to 54Mbps transfer rate can be achieved, in fact lower. If the wireless mini pci card and wireless router, there is an obstacle between, the rate will be subject to greater impact.
2 USB and PCMCIA aegis
By interface points can be wireless card into PCI, USB, PCMCIA three types, different interfaces can be installed on different computers. When purchasing wireless network card to a computer interface according to their own choice.
USB wireless cards are generally divided into two kinds of USB 1.1 and USB 2.0, IEEE 802.11b standard in the early products to use more USB 1.1 interface, then the IEEE 802.11g standard products more use of the USB 2.0 interface, such as TP-LINK TL-WN320G and so on. USB interface with plug and play, easy installation, high-speed transmission, no power supply and other characteristics, compatibility, very strong. Suitable for mobile office users as well as there is no free laptop PCMCIA interface users.
PCMCIA interface can also be divided into 16-bit PCMCIA and 32-bit CardBus. At present, most wireless mini pci-e bluetooth wifi card is available in 32-bit CardBus interface, such as TP-LINK TL-WN610G, etc. The interface also has a plug and play, high-speed transmission and so on. In fact, PCMCIA interface, better integration with the laptop, together with the effect of the use of better, but also can save a USB port.
In addition, there is a common PCI interface, a wireless network card, the card for desktop computers, installing them is relatively complicated.
3 maximum transmission distance
In the product specification is generally marked on the wireless card's theoretical maximum transmission distance, the actual distance is less than positive mark value. Many consumers buy wireless network card in order to share Internet access, live in the house if the relatively large, or from the wireless router (or wireless AP) distance from the distant, the purchase of the wireless card products are often of particular concern when the maximum transmission distance of , over-emphasis on maximum transmission distance
In the wireless local area network, the receive and transmit signals using the transmission medium is air, radio signals are susceptible to atmospheric noise, the environment and the interference of other signal transmitting equipment, in particular, wireless network equipment, radio-wave devices, such as household microwave ovens, cordless phones , similar wireless LAN equipment. If at home or near the source of these disturbances will affect the wireless card to receive and transmit signals a distance.
In fact, China's current average home, install an IEEE 802.11b-compliant wireless LAN and wireless routers, within the field of vision, without obstructions or other interference sources, the wireless signal can basically cover most of the space. The past two years the factory standard IEEE 802.11g wireless LAN products, the largest distance have some improvement.
Therefore, when buying the wireless card, most well-known brand-name products is not the gap between the transmission distances, do not over-emphasis on maximum transmission distance indicators.
4 security mechanisms
Through the WEP and other encryption technology can ensure the wireless LAN to send and receive data security, prevent unauthorized users intrusion. The higher bits WEP encryption, hacking more difficult the larger the higher the safety factor.
At present, the wireless LAN security mechanisms used include WEP data encryption, WPA encryption, IEEE 802.1X authentication. Most wireless LAN products support these security mechanisms, different is that support for WEP encryption bits is different from present, most wireless LAN products support 64/128 bit WEP encryption, and some product support 152-bit WEP encryption, a small amount of product support 256-bit encryption
So,t he purchase of your home wireless mini pci-e card, when used according to their own wireless router or wireless AP to select the appropriate wireless mini pci card, such as the wireless router set up 152 WEP encryption, you must choose to support 152-bit WEP encryption The wireless card products.
