3G modems are a compact device that looks like an ordinary USB flash drive and allows you to access the Internet using third generation mobile technologies. This type of modem is widely used to connect to the Internet using a laptop, so it is important to know the parameters by which they should be selected.
Description of 3G-modem
Modern 3G-modems combine high-speed connection to the world network and radio communication. They connect to a laptop via a USB port, a universal interface supported by all laptops, netbooks, computers, and Wi-Fi routers. 3G modems differ from standard modems in maximum compactness and the ability to connect to the Internet anywhere where there is coverage. In addition, manufacturers equip many of their models with slots for MicroSD cards, which gives a 3G modem the quality of a regular flash drive, on which you can store files and the necessary documentation.
Some 3G modems can be connected to a GPS navigator, which allows you to navigate the terrain, as well as an external antenna.
As for the disadvantages of 3G modems, they mainly consist in the binding of the device to a particular mobile operator. However, if necessary, the modem can be reoriented by changing the SIM card. Also, 3G-modems are made of plastic, which significantly reduces their service life - especially with intensive use. Many mobile operators claim fantastically fast data transfer in the characteristics of the device, which is quite expensive - while most 3G modems transfer information at the same speed.
Choosing a 3G modem
When choosing a 3G modem for a laptop, first of all, you need to study the proposals in three main categories - namely, the cost of the device, its technical capabilities and characteristics, as well as design. The cost in this case is not fundamental or decisive - each user can choose a 3G modem according to his wallet, but it is recommended to buy it exclusively in trusted stores.
Before purchasing a modem, it is important to decide whether it needs to have additional features in the form of a flash drive or other bonuses from the manufacturer.
As for the technical characteristics, it is important to pay main attention to the speed of data transmission and reception - and not to the speed of the tariff plan, but to the device itself. If the tariff plan does not suit you, you can always change it.
Design solutions for 3G modems are offered today in a variety of ways, but experienced users recommend making sure that there is one important characteristic when choosing. A high-quality case of a 3G modem should be made of shock-resistant rubberized plastic, which will allow the device to last much longer than its standard plastic counterparts.
