What Is a USB Wireless Device?

USB wireless network card, a network card with a built-in wireless WIFI chip and transmitted through the USB interface, connected to the computer USB interface, after the driver is installed, a new wireless network card device will appear in the computer network card list. Go online via USB wireless network card.

USB wireless network card and commonly used

USB wireless network card is commonly used SB 2.0, 1.1, 1.0 Redltek 8187L chip and Ralink 3070 chip. Advantage, welcomed by cottage manufacturers.

The higher the sensitivity of the "Redltek 8187L chip", the larger the search range, the greater its power, and the greater the harm to the human body. The USB wireless network card uses a low-radiation and high-sensitivity Ralink 3070 chip. The radiation will be processed through complex processes and the radiation will be effectively controlled. The Ralink 3070 chip has made a major breakthrough in this regard and controlled within the range of human health and safety. Compared with Ralink 8187L, the radiation of Ralink 3070 chip reduces 82% under the same power network card, and the radiation is 18% of Redltek 8187L. Its radiation is equivalent to 36% of mobile phones.

uW is a unit of power, W represents watts, 1W = 1000mW, 1mW = 1000uW, reading W (watt), mW (milliwatt), uW (microwatt). 2. What is mG? MG is read in Gaussian. The value of electromagnetic waves is measured in magnetic flux density units MG (milli Gauss). 10uW / cm2 is about 1MG, and the mobile phone radiation is about 200mg, so 1800mw = 180000MG

Core chip support technology automatic detection function, the maximum throughput can reach 150Mbps, support technology WPA,

The common encryption of wireless networks is known to have WEP and WPA encryption. In fact, there are other different restrictions on wireless networks such as binding IP, MAC filtering, and turning off DHCP. If the connected network has such restrictions, then even The other party is not encrypted and cannot access the Internet.

Judging method: The wireless network card is connected to the network (with the correct password and encrypted), and can automatically obtain the IP and access the Internet normally, which means that the other party has only one type of encryption restriction. Such restrictions are used. The IP can be obtained automatically, and it is connected, but cannot access the Internet, which may be other restrictions on the other party, such as the other party's no Internet fee and so on.
