Device type

USB modem. Modems in the form factor of a USB stick that is connected to a computer, laptop or other devices via an unoccupied USB port. These can be either the simplest devices for servicing one client device (to which the modem is directly connected), or more advanced models with support for Wi-Fi networks and the ability to wirelessly distribute the Internet to several gadgets. To access the World Wide Web, USB modems provide a slot for a SIM card.

Portable router. Mobile routers for Internet access, necessarily with a built-in Wi-Fi module. Wi-Fi modems are capable of simultaneously working with several connected devices; in addition, they are battery-powered and can be used completely autonomously - without the need to connect to a computer and an outlet. It is advisable to use portable routers in cases where a fixed connection to the Internet is difficult or completely absent (at the dacha, outdoor recreation, as backup equipment for accessing the global network).

Wi-Fi

Wi-Fi connection speeds, more precisely, Wi-Fi standards supported by a modem with the appropriate capabilities (see "Type", "Connection").

— Wi-Fi 3 (802.11g). A further development of the Wi-Fi 1 (802.11b) standard, developed primarily for increasing connection bandwidth (2.4 GHz) and introduced in 2003. 802.11g hardware is fully backwards compatible with 802.11b, so even the simplest of today's Wi-Fi devices support both of these standards.

— Wi-Fi 4 (802.11n). The Wi-Fi standard, which is a further development of the formats described above — in particular, by supplementing them with support of MIMO technology (distribution of input and output between several antennas). Introduced in 2009. The main operating frequency is 2.4 GHz, but there are devices supplemented with a 5 GHz band.

Wi-Fi 5 (802.11ac). Built on top of 802.11n, introduced late 2013. The main improvements were the increase in the number of streams at the second frequency (5 GHz) and the introduction of more advanced MIMO and modulation standards, which increased the throughput accordingly.

Connected devices, up to

The largest number of devices that can be simultaneously connected to the modem via Wi-Fi (see "Connection").

The presence of this limitation is due to the fact that processing network requests from several devices at once requires a fairly large amount of computing resources, and there are not so many of them in miniature electronics like wireless modems. However, even inexpensive models can support about 5 – 6 devices, which is more than enough for most cases; and in more advanced modems, this number can reach 10.

Effective range

The greatest distance at which the modem's built-in router is capable of providing communication via the Wi-Fi interface (see "Connection").

It should be taken into account that in fact the range strongly depends on a number of factors that are not related to the main specs of the modem: the presence of interference and obstacles in the signal path, the specs of the Wi-Fi module of the connected device, the battery charge in this device or the modem itself, etc. Therefore, the actual range indicators can be noticeably lower than the claimed ones: for example, when working through a wall, they are noticeably reduced. However, this spec quite clearly describes the overall range of the device, and comparisons of different models on it are quite acceptable.

Also note that it does not always make sense to purchase a device with a maximum range — although a long range provides additional convenience, it requires high transmitter power, which significantly increases the size and price of the modem. Therefore, when choosing, it is worth proceeding primarily from the intended scenarios of use. For example, if you need a 3G connection to access the Internet on the road from your tablet, a range of several metres will be enough. But for installation in a large private house, it makes sense to look for a model with increased effective range.

Ports

USB plug. The presence in the design of the modem of its own USB plug, which allows you to connect the device to a computer directly. Such a connection provides a device with a USB port with Internet access, and the power necessary for the operation of the modem is also supplied via USB.

microUSB. A smaller version of the USB connector (see above), used primarily in Wi-Fi modems (see "Type") that can work autonomously and do not require a constant connection to another device. At the same time, in 3G/4G modems, microUSB usually looks like a socket, not a plug, and a special cable is used to connect. This interface usually plays the role of a general-purpose service connector: the battery is charged through it, and it is also connected to a PC or other device to manage settings, update firmware, etc.

USB. Wired interface, the most common and universal modern standard used to connect peripheral equipment to various electronic devices, ranging from computers to smartphones and even wireless modems. In this case, the full-size version of the USB connector is meant. It is usually installed in classic modems (see "Type") and has the form of a plug, with which the modem is connected to a control device (PC, laptop, tablet, etc.). Power is usually supplied through the same connector.

...>USB-C. Connector, in its functional features similar to the paragraph above. With the exception of the symmetrical form factor and the use of more modern technologies.

LAN (RJ45). Classic wired connection via a cable with an RJ-45 connector. Also known as "LAN". Nowadays, it is one of the most common methods of wired Internet connection, and is also widely used in local networks. With it, you can connect a laptop or PC directly to the modem via a cable and not bother with a Wi-Fi connection. In addition, such a connection can be faster (depending on the speed of the LAN).

— ExpressCard. A connection interface mainly used in laptops. Peripheral devices of this standard, including wireless modems, have the form of cards, when connected, they are installed in a special slot in the device. It should be taken into account that there are two ExpressCard form factors — 54 mm and 34 mm, and 34 mm cards can be used without restrictions with 54 mm slots, but not vice versa. Therefore, when choosing such a modem, it is worth clarifying the correspondence of its form factor to the planned slot. However, this standard is gradually disappearing from the scene, being replaced by more advanced interfaces — in particular, USB 3.0.

GPS

The presence of a GPS module in the design of the modem. This module allows you to track the current geographic coordinates of the device; but the options for working with coordinate data can be different. The most popular way to use such models is to use them as an external GPS module for a laptop or other device.

Display

The presence of a display in the design of the modem. Even the simplest screens used in modern modems are very versatile and capable of displaying almost any service information about the operation of the device (and sometimes not only purely service information). Due to this, this feature provides much more opportunities to inform the user than various indicators. At the same time, we note that this feature is found only in Wi-Fi modems (see above) designed for stand-alone use. This is due to the fact that in models that are connected to another device via USB, the screen of the external device is used for displaying this information, and it simply does not make sense to equip the modem with its own display.

Built-in battery

The presence of a built-in battery in the modem. Relevant for models with Wi-Fi support. Such modems are designed to be used as stand-alone equipment and do not require a wired connection to a control or power device such as a PC or laptop. This ensures maximum mobility. On the other hand, the battery charge is not infinite: it usually lasts for several hours (see paragraphs about the operating time in different modes), after which the battery still needs to be charged. In addition, the presence of built-in batteries significantly affects the dimensions, weight, and most importantly, the price of modems.

Battery capacity

The capacity of the battery installed in the modem with the corresponding type of power supply (see below).

The higher the capacity, the longer the battery is able to work without recharging, all other things being equal. However, note that the situation of "other things being equal" is almost not found in modern wireless modems. First, different data transmission technologies (see above) have different power consumption; secondly, even models supporting the same standards can differ in power consumption (and battery life) due to design differences. Therefore, this indicator in most cases is purely reference information, and even very similar models can only be compared approximately. When choosing, it is worth focusing primarily on the claimed specs of the battery life (see below).
