When choosing a wireless device for connecting to the Internet, today you can face a problem - a fairly wide range of 3G modems. Yesterday there were less than 5 such devices in the salons of cellular communication, and today there are already about ten of them.

Step 1
Immediately, it is worth noting the main criteria for choosing the desired wireless device. First, there is the price barrier. Secondly, the characteristics of the purchased device. Here, parameters such as outbound and inbound speeds, as well as equipment, will be important. Thirdly, the appearance (design) of the modem. It counts if you are looking for a modem to give a gift.
Step 2
First of all, it is worth making a small amendment that another criterion, albeit not the most important, is the device's connection interface. Today, there are 3 types of connection of the device to a computer: USB-version, PCMCIA-version and PCMCIA Express version. The above interfaces are equally compatible with personal computers, laptops and netbooks.
Step 3
USB is considered the most common and versatile interface for wireless modems. Such a modem can be connected to any computer device, even to a router or router that supports this connector. The ultra-small size of the wireless device allows developers to add some useful features, such as the ability to connect small flash cards to use it as a storage device. Another advantage of this type is the variety of modem cases. But this point also contains a minus - the low shock resistance of the device.
Step 4
PCMCIA modem. The width of this device is 54 mm, which indicates its high dimensions. This device is already out of production, but it is still produced and used on laptops of the "old" generation. The maximum data reception speed of this device is much lower than that of a 3G modem.
Step 5
A more advanced model of the PCMCIA modem is PCMCIA Express. Here the slot is much narrower, only 34 mm. This protocol is characterized by improved design and ergonomics. This device is mounted in a laptop case, and there is only an antenna outside. The connection speed is already close to the speed of a 3G modem and in some cases can compete for the title of the fastest modem.
Step 6
Also, an important parameter when choosing a wireless device is the cellular operator, whose SIM card you will use. There are regions where one and the same operator can provide high quality telephone communications, but the Internet will work much worse.
