What is a USB-modem

The use of this electronic mechanism does not require any special knowledge from the user to connect to the World Wide Web. Almost all modern 3G CDMA and GSM modems now have slots designed for memory cards, and this allows them to also be used as flash drives. Installation of these devices takes no more than five minutes, and with the management interface can be understood by any student.

Features of use

As a rule, the USB-modem is inside a durableplastic housing, which perfectly protects it from damage. The only thing that he does not like is storage in a humid place and disconnecting from the system without using the built-in Windows function to safely remove the devices. For the sake of justice, it is worth noting that, in addition to its unique advantages, the USB-modem has a number of small drawbacks. First, it can not work autonomously, without connecting to a PC. Secondly, all the drivers, again, are in the memory of the device to which it was installed, and therefore if you just connect it to the corresponding connector of someone else's laptop, there may be some problems. Thirdly, in rare cases, but still it happens that the Windows Setup Wizard simply can not recognize and install the USB-modem. Well, fourthly, in hard-to-reach places, communication with the network (depending on the operator) may disappear, which can not guarantee a stable operation on the Internet.

However, to do this, you first need to check whether there ison the modem corresponding connector. In urban conditions there will be quite enough an undirected antenna, which, as a rule, is installed on the windowsill, and in rural areas a directed antenna is oriented towards the base station of the operator.
