What is a USB-modem and how can I increase its speed

The importance of timely and timely information in the 21st century has grown so much that few people now do without the Internet, its main source. And if we add to this the mobility of modern life, it becomes clear why the USB-modem in our time is so rapidly gaining popularity. Let's figure out what kind of device it is, how it works and how you can increase the speed of its operation.

What is a USB-modem

This rather simple and practical electronic device was specially invented in order to be able to access the Internet directly via the USB port of a laptop, tablet or a conventional desktop computer. 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 any student can understand the management interface.

Features of use

Typically, the USB-modem is inside a durable plastic 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.

How to increase the speed of 3G modem reception

Note that before buying a modem it is desirable to pre-test it in the area where you will most often use it. Now the most popular MTS-modems, which are distinguished by a favorable price and good reception quality. But if you are faced with poor communication quality, try using our tips. One of the most affordable ways to increase the speed of the modem is to use a sufficiently long USB extension cable. Just find a place where the link indicator (the number of vertical sticks) will be the highest, and leave the device there. The second option is the purchase of an antenna. However, to do this, you first need to check if there is an appropriate connector on the modem. 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. In the latter case, the cable length should not exceed 10 m. The third method consists in flashing the modem. But if nothing helps, you can try specially designed for this program. True, this option is extreme, and resort to it is at your own peril and risk.
