【 Weak current College 】 wireless and wireless Internet card differences

Wireless network adapters and the wireless network card?, although the difference between just one word, but the two concepts. To have different access requirements for user convenience. Many novice users often confuse these two devices, and some businesses in sales promotion is sometimes confused these two devices, the introduction of such a device often combine two mixed up the capabilities of the device, such as "our wireless network card can be composed with other wireless network card wireless network", but certainly they would not be a device. First of all let's take a look at wireless and wireless network card is all the difference:
Wireless network card:
Wireless network card's role, function and general computer network card, is used to connect to the LAN. It is only a signal transceiver device, only found on the Internet can only be achieved when the export with Internet connection, all wireless card can only be confined to already have a wireless LAN.
Wireless network adapter is not connected through wired, wireless signal to connect the network adapter. Wireless network card based interface, mainly in the PCMCIA wireless card, PCI Wireless card, MiniPCI wireless card, USB wireless network cards, CF/SD wireless card categories of products.
From speed, wireless Internet card now mainstream of speed 54M and 108M, the performance and the environment has a lot to do.
54Mbps: its WLAN transmission speed is generally between 16-30Mbps, convert MB which is per second transmission speed in 2MB-4MB. Take one of values between 3MB, such a speed that you want to transfer files need 100Mbit 35 seconds or so, you want to transfer to 1 GB of files, you need at least 4 minutes.
108Mbps WLAN transmission speed which is generally between 24-50Mbps, conversion into MB which is per second transmission speed in 3MB-6MB. Take one of values between 4.5MB, such speed to transfer 100Mbit files need 25 seconds or so, you want to transfer to 1 GB of files, you need at least 2 and a half minutes or more.
Wireless network card:
The role of the wireless network card, the function is equivalent to a cable modem, we commonly known as the "cat". It can have a mobile phone signal coverage anywhere, the use of mobile phone SIM card to connect to the Internet.

Wireless network card's role, functions as a modem wuxianhua (MODEM). Their common interface types also have PCMCIA, USB, CF/SD, interface type.
From speed, wireless Internet access cards are divided into two kinds of GPRS and CDMA. Its speed is affected by walls and other obstructions, other wireless signals such as mobile phones, microwave ovens, etc.
The actual speed of GPRS: basic and 56 Kbps Modem speed.
Actual speed: CDMA reached 153.6Kbps, is home to four times the telephone line.

Wireless network card and a wireless Internet card:
Wireless network card and a wireless Internet card looks like, but the function is quite different. Through this more visible, although both can implement wireless Internet capabilities, but its implementation modalities and approaches are quite different. All wireless network card can only be confined to already have a wireless LAN. If you are in a wireless local area network coverage, which is achieved via a wireless wide area network, wireless Internet capabilities will have a wireless computer network card on the basis of, and configure wireless network card.
As the mobile phone signal coverage in place far greater wireless LAN environment, all wireless Internet card dramatically reduces dependence on the geographical aspects, to the vast number of individual users, easier to apply. Therefore, the wireless network card and a wireless Internet card although can achieve wireless functionality, but the ways and means of implementation are completely different.
Summary:
Wireless network card is mainly used in wireless LAN to LAN connectivity, to have a wireless router or wireless access point such access equipment can use, and the wireless network card as normal as used in mobile phone 56KMODEM signal can be covered anywhere Internet access, the novice should pay attention to the difference.
