What is a mobile network card?

3G network card is a widely used medium in wireless wide area communication network. At present, there are three network standards in China: mobile td-scdma, telecom CDMA2000 and Unicom WCDMA, so the common wireless network cards are CDMA2000 wireless network cards and td and WCDMA wireless network cards.

Wireless network card: Wireless network card is the equipment of terminal wireless network, and it is the wireless terminal equipment that accesses the Internet through wireless connection network under the wireless coverage of wireless local area network. In other words, if wireless routing is regarded as a signal transmitter, then the wireless network card is a signal receiver. Wireless network card: Wireless network card is a widely used Internet medium in wireless wide area communication network. In China, there are three network standards: China Mobile's edge, td-scdma and China Telecom's cdma (1X), so the common wireless network cards are CDMA wireless network cards and EDGE, td-scdma wireless network cards. 3G wireless network card-classification of various 3G network cards GPRS (General Packet Radio Service): 56 or even 1 14Kbps. Edge (Enhanced Data Rate for GSM Evolution): The highest rate can reach 384kbps, generally about 200 kbit/s, and Td-scdma (Time Division Synchronous Code Division Multiple Access) is 384kbps. HSDPA: High-speed downlink packet access technology. HSDPA of TD-SCDMA: the highest is 2.8Mbps, the latest market products reach 3.6m, and the laboratory products reach 33MCDMA2000 1X EV-DO (which can be understood as HSDPA of CDMA2000): countries such as Korea and Japan have reached the peak rate of 2.4Mbps, and HSDPA of WCDMA: the theoretical maximum can reach 14.4 Mbps. In Hongkong, China, Taiwan Province Province, China, South Korea, Europe, the United States and other countries or regions, the speed can basically achieve 3.6Mbps, and a few areas can achieve 7.2Mbps.
