About 3G connection, modems and which one to choose

If you like to travel and want to keep abreast of all events, you will need the Internet, especially for those who have work related to the Internet. Wi-Fi is of course an option, but not everywhere it is, and if it is, it operates at a short distance, and access to Wi-Fi can be paid, and it is not economically profitable to pay for such Internet everywhere. The best solution for such people is 3G Internet, which has gained popularity in almost all countries and has a large coverage. You will need a netbook, tablet, or laptop, and of course you will need to purchase a 3G modem. 3G modem is the best option to be regularly on the Internet.

What you need to know when buying a 3G modem

First of all, you need to decide in advance which operator you plan to connect to. Having made an exact decision, choose a 3G modem, it is desirable that the modem matches your operator. Check with your carrier which 3G modems they support.

Rev A and Rev B

Today, modems have two main types of standard Rev B and Rev A, they differ in bandwidth, which means that the speed of these standards is different. Rev A technology modems have a bandwidth of 3.1 Mb. sec, and Rev B 14.7 mb. sec. The speed test of these modems was carried out in laboratories where there was a good communication signal with the station, and the station was not loaded. This means that you are unlikely to get the speed promised by the manufacturer elsewhere. In some especially populated areas, the speed rarely reaches 2 mb. sec on the Rev A standard, and the Rev B standard in such populated areas will not help you, since it's not a modem, but a bad connection or a heavy station load. And the cost of modems with the Rev standard is almost twice as high as the Rev A standard.

External antenna

An external antenna is used to improve 3G coverage, it is used if the operator's 3G coverage is poor. In such cases, an external antenna is used, but to use such antennas, the modem must contain a connector for such an antenna, and they are not present on all modems.

Memory card for 3G modem

Almost all modems have a slot for memory cards, usually when buying a 3G modem, the buyer does not pay attention to this. Of course, this may be a trifle, but still additional memory where you can store documents, music, photos, programs, etc. will always come in handy.

Modem firmware for a telecom operator

When choosing a 3G modem, be sure to find out the modem is flashed for a specific operator, or not. It is better to choose non-flashed modems, which means that such a modem supports almost any operator. And the cost of non-flashed modems is usually cheaper. For example, you use a certain operator, and this operator raises the tariff, of course, this is not beneficial for you. If your modem is not flashed, you can easily replace the operator with a more profitable one. In flashed modems, this will not work. Since the modem simply will not catch the connection with the new operator, and will only work with the operator for which it is flashed.

What is the best 3G modem for a tablet

Until now, most tablets do not support 3G modems, but there is a way out, you can use a battery-powered 3G modem with Wi-Fi. For example, a modem such as the Huawei E5331 can do this.

Such a modem not only works in 3G but is also capable of providing an access point via Wi-Fi.

Which operator to prefer for a 3G modem

When you choose a 3G modem stitched under the operator, your choice in modems will decrease significantly. With this choice, specify which places the operator covers, and how well he does it, it is also important to get acquainted with the operator's tariff plan. Tell the operator where you will often use the 3G modem. Decide what is more important for you, Internet speed, or low tariff fees, these two factors are difficult to achieve together. If you plan to use a modem in your city, then choose the best operator in the city, if you need high-quality communication in several cities, then the operator must have good coverage in these cities.

It is better to buy 3G modems from an operator that has unlimited tariff, in this case, you will pay once a month, and not by the amount of megabytes spent. Today, Huawei modems are gaining popularity, pay attention to them, perhaps such a manufacturer will be the best solution for your tasks.
