In Windows 8, you can directly deal with mobile networks such as 3G/LTE.
From Windows7, the mechanism of dealing with 3G and other mobile networks has been changed. Before Windows XP, the hardware of the mobile network was used as a "modem" in dial-up networking. It is the same as wireless LAN and so on, and it is handled in the network interface. It was originally planned to be implemented in Windows Vista.
However, due to various reasons, the development is slow, from Windows7 to the mobile network "Mobile Broadband Network" (Mobile Broadband Network). As MBN) processing becomes possible. In addition, the term "mobile broadband network" of Windows will be abbreviated to MBN later.
In the mobile network, there are 2G, 3G, LTE and other kinds, in MBN, it is roughly divided into GSM system and CDMA system to deal with. This is because there are differences in the structure of the core network after the base station. In addition, the so-called "W-CDMA" in Japan is collectively referred to as UMTS (Universal Mobile Telecommunications System), which uses the same structure as GSM in the architecture on the core network side.
W-CDMA is the name for the wireless part of UMTS (the mode of communication between the terminal and the base station). In addition, CDMA system corresponds to CDMA2000 and other methods adopted by au in Japan. In addition, LTE is a GSM system. In the case of use, there is no need to distinguish between the two, but the table token of the connection method is sometimes "UMTS" or "HSDPA". Specifically, the following statements are sometimes made.
GSM system: GPRS/EDGE/UMTS/HSDPA 1/LTE/TS-SCDMACDMA system: 1xRTT/3xRTT/1xEV-DO/1xEvDO RevA/RevB 2
"1:HSDPA (High Speed Downlink Packet Access) means the high speed of downlink, sometimes collectively referred to as HSPA (High Speed Packet Access) with uncertain direction 2: periods such as" Rev.A. "and" Rev.B. "are included in the official name, but are omitted in the MBN table.
In Windows7, although the basic structure of MBN is imported, it is basically assumed to provide operators with necessary drivers, software, and connection destination information for services, such as wireless LAN or previous dial-up modems. User settings and use of these are not taken into account. Therefore, it is difficult to ship as a PC without SIM, and PC, as a communication carrier, has several levels of sales.
In the current Windows8.1, as long as NDIS drivers are available, users can not only set APN from GUI, but also provide APN database, APN settings of major operators, etc., which can be carried out automatically by Windows.
