Product type

General device type. Nowadays, in addition to the routers familiar to many (both regular and gaming), you can find ADSL routers, access points(including directional ones), MESH systems, Wi-Fi adapters, Wi-Fi amplifiers and even satellite Internet terminals on the market. Here is a detailed description of these types of equipment:

— Router. Devices known to many as the most popular means of wireless Internet access. However, the use of such electronics is not limited to this — it can also be used to create local networks and for some other, more specific purposes. On the technical side, a router is an access point to a wireless network that supports NAT mode; for more details about this mode, see "Functions and Capabilities", here we note that it is thanks to NAT that it is possible to access the Internet from several computers / gadgets at once, working through one provider account.

— Gaming router. A variation of the routers described above, optimized for use in online games. The features of such devices are support for the latest communication standards, high connection speed with a minimum of lags, as well as the availability of special tools and funct...ions (game traffic priority, connection accelerators, integration with gaming services or even certain online games, etc.). The specific functionality of a gaming router may be different, but if you strive for maximum speed and comfort in online games, it makes sense to choose a device from this category.

— ADSL modem/router. Wireless routers (see above) that provide Internet access through ADSL technology. The key benefit of this technology is that it allows the use of existing telephone networks without the hassle of running wires; at the same time, the Internet and telephone communication work independently and do not interfere with each other. On the other hand, such a connection is inferior to wired Ethernet in terms of speed and functionality (for more details, see "Data input (WAN-port)"); therefore, nowadays, ADSL is gradually “departing from the stage”, and there is not much equipment for this technology on the market.

— Access point. Devices intended mainly for use as a kind of "adapter" between wired networks and wireless devices, as well as for connecting individual network segments to each other via a wireless channel. The fundamental difference between such devices and routers (see above) is the absence of the NAT function (see "Functions and Capabilities") — thus, each wireless device connected to the access point transmits its own IP address to the network. A typical example of a network based on such equipment is a common router for connecting to the Internet, plus several access points located in key locations and connected to the router by wire.

— Directed access point. A variation of the access points described above, in which the coverage area has a clear direction. Simply put, the signal from such a device does not diverge uniformly in all directions, but in a certain direction, in the form of a beam or sector. Such equipment has two main areas of application. The first is situations when the access point needs to be installed not in the centre, but on the edge of the overlapped zone — for example, in the corner of the room. In this case, the directional design allows you to concentrate almost all the transmitter power in the working area, without wasting it on "unnecessary" directions. The second use case is wireless communication over long distances, for example, between networks in different buildings in bridge mode (see "Features"); in some directional access points, the communication range reaches 10 km. Of course, for such communication, the device on the other side of the wireless channel must also have the appropriate range, so the easiest way in such cases is to use two access points with the same characteristics.

— MESH system. Equipment for building wireless networks in MESH format. The idea of this format is to use numerous compact and relatively low-power wireless transceivers that can interact with each other in a coordinated manner. In this way, you can block a significant area (up to a small city), providing a reliable connection at any point in the coverage area. This happens as follows: a laptop, smartphone or other Wi-Fi gadget interacts with the nearest node of the MESH network, then the data is transmitted to the main router or access point wirelessly, along the chain between the nodes. In this case, the so-called dynamic routing is used: the network itself determines the optimal data transfer path and automatically changes this path when the user moves between individual nodes.
Actually, dynamic routing is the key difference between MESH devices and more traditional Wi-Fi amplifiers. At the same time, the work is carried out in a “seamless” format: when switching from one node to another, the connection is not lost and network functions that require a stable connection (downloads, watching videos, online games, authorization sessions) are not interrupted. In other words, the user does not notice switching between individual nodes at all. In addition, this format of operation allows you to maintain a stable connection speed (whereas the use of traditional amplifiers, especially in the form of chains, significantly reduces the speed). Thus, a MESH network can be an excellent solution for situations where a set of several Wi-Fi amplifiers is needed — from a private house on 2-3 floors to office and industrial complexes, and even urban areas. At the same time, equipment for such networks can be sold in sets of several units (up to 8); see "Included" for details.

— Wi-Fi adapter. Adapters for connecting to Wi-Fi networks designed for desktop PCs and other equipment that does not initially have built-in Wi-Fi modules. Such equipment can be both external and internal — see "Interfaces (for adapters)" for details. Also note here that buying a Wi-Fi adapter can be a good alternative to a wired connection — especially if the router is located far away and it would be inconvenient to pull the wire.

— Wi-Fi booster. Devices designed to amplify the Wi-Fi signal from an existing router or access point. They allow you to expand the coverage area, get rid of "dead zones", as well as improve the overall quality of communication and make the signal more stable. This type of device differs from MESH equipment (see above), which has a similar purpose, in the absence of dynamic routing (Wi-Fi amplifiers are designed to work directly with the router, in extreme cases, via a fixed chain), as well as the impossibility of seamless operation (the amplifier is visible as separate network — see "Features — Repeater Mode" for details). In addition, connecting through such a device can significantly reduce the speed. On the other hand, Wi-Fi amplifiers are much cheaper than nodes in MESH systems. So this particular type of equipment may be the best option for simple domestic use, when you only need to slightly expand the existing coverage and there is no need to build an extensive network with many equivalent connection points.

Satellite Internet (Starlink). Terminals for accessing the World Wide Web via satellite communications. The infrastructure of such systems usually consists of low-orbit satellites in space, a network of base stations on the ground, and client terminals directly for receiving signals and distributing the Internet. The monopolist in this area is Elon Musk’s company SpaceX with its Starlink terminals.

With the introduction of satellite systems into mass use, it became possible to provide high-speed Internet access in places where this was previously impossible due to the lack or poor development of traditional methods of data transmission. At the same time, such Internet will come in handy during regular power outages and far from electrical civilization. The main thing is to power the client terminal. Among the disadvantages of the technology, the high cost of equipment and the high monthly fee for using satellite Internet services (compared to a traditional cable connection or using mobile access to the global network) are noted.

LAN

In this case, LAN means standard network connectors (known as RJ-45) designed for wired connection of LAN devices — PCs, servers, additional access points, etc. The number of ports corresponds to the number of devices that can be directly connected to wired equipment. way.

In terms of speed, 100 Mbps (Fast Ethernet) and 1 Gbps (Gigabit Ethernet) are the most popular options today. At the same time, thanks to the development of technology, more and more gigabit devices are being produced, although in fact this speed is critical only when transferring large amounts of information. At the same time, some models, in addition to the standard speed of the main LAN ports, may have a 2.5 Gbps, 5 Gbps and even 10 Gbps LAN port with increased bandwidth.

Gain

Gain provided by each device antenna; if the design provides for antennas with different characteristics (a typical example is both external and internal antennas), then the information, usually, is indicated by the highest value.

Amplification of the signal in this case is provided by narrowing the radiation pattern — just as in flashlights with adjustable beam width, reducing this width increases the illumination range. The simplest omnidirectional antennas narrow the signal mainly in the vertical plane, "flattening" the coverage area so that it looks like a horizontal disk. In turn, directional antennas (mainly in specialized access points, see "Device type") create a narrow beam that covers a very small area, but provides a very solid gain.

Specifically, the gain describes how powerful the signal is in the main direction of the antenna compared to an perfect antenna that spreads the signal evenly in all directions. Together with the power of the transmitter (see below), this determines the total power of the equipment and, accordingly, the efficiency and range of communication. Actually, to determine the total power, it is enough to add the gain in dBi to the transmitter power in dBm; dBi and dBm in this case can be considered as the same units (decibels).

In general, such data is rarely required by the average user, but it can be useful in some specific situations that specialists have to deal with. Detailed calculation methods for suc...h situations can be found in special sources; here we emphasize that it does not always make sense to pursue a high antenna gain. First, as discussed above, this comes at the cost of narrowing the scope, which can be inconvenient; secondly, too strong a signal is also often undesirable, for more details see "Transmitter power".

Transmitter power

Rated power of the Wi-Fi transmitter used in the device. If multiple bands are supported (see “Ranges of operation”) the power for different frequencies may be different, for such cases the maximum value is indicated here.

The total transmitting power provided by the device directly depends on this parameter. This power can be calculated by adding the transmitter power and the antenna gain (see above): for example, a 20 dBm transmitter coupled with a 5 dBi antenna results in a total power of 25 dBm (in the main antenna coverage area). For simple domestic use (for example, buying a router in a small apartment), such details are not required, but in the professional field it often becomes necessary to use wireless devices of a strictly defined power. Detailed recommendations on this matter for different situations can be found in special sources, but here we note that the total value of 26 dBm or more allows the device to be classified as equipment with a powerful transmitter. At the same time, such capabilities are not always required in fact: excessive power can create a lot of interference both for surrounding devices and for the transmitter itself (especially in urban and other similar conditions), as well as degrade the quality of the connection with low-power electronics. And for effective communication over a long distance, both the equipment itself and external devices must have the appropriate power (which is far from alway...s achievable). So, when choosing, you should not chase the maximum number of decibels, but take into account the recommendations for a particular case; in addition, a Wi-Fi amplifier or MESH system often turns out to be a good alternative to a powerful transmitter.

CPU cores

The number of cores in the processor installed in the device. The core in this case refers to the part of the processor that executes one thread of instructions. Accordingly, the presence of multiple cores (there are 2-core models, 3 and on 4 cores) allows you to work with multiple threads simultaneously, which has a positive effect on performance.

Clock Speed

The number of cycles per second that the processor produces in its normal operating mode. A clock is a single electrical impulse used to process data and synchronize the processor with the rest of the computer system. Different operations may require fractions of a clock or several clocks, but anyway, the clock frequency is one of the main parameters characterizing the performance and speed of the processor — all other things being equal, a processor with a higher clock frequency will work faster and better cope with significant loads.

RAM

The amount of random access memory (RAM) provided in the device. The amount of "RAM" is one of the indicators of the power of the device: the larger it is, the higher the speed and the better the device will cope with "heavy" tasks. Among the values, there can be 128 MB, 256 MB, 512 MB and high scores in 1 GB and 2 GB.

Flash memory

The amount of memory allocated for the operation of the operating system on board the router. It stores the OS and the control programme. Note that Flash memory is not available for use by the end user.

Features

The main functions and capabilities implemented in the device.

This category mainly includes the most key functions — namely load balancing (Dual WAN), channel reservation, Link Aggregation, Bluetooth(various versions, including Bluetooth v 5), voice assistant, NAT, MESH modes, bridge, repeater, Beamforming function , firewall (Firewall) and CLI (Telnet). Here is a more detailed description of each of these items:

— Dual WAN. Possibility of simultaneous connection to two external networks. Most often used for simultaneous work with two Internet connections (although other options are possible); at the same time, there are two main modes of operation with such connections — redundancy (Failover / Failback) and balancing (Load Balance). So, in backup mode, the device constantly uses the main channel to connect to the Internet, and in case of failures on this channel, it automatically switches to a fallback option. In balancing mode, both channels are used simultaneously, while the load between them is distributed either automatically (depending on the traff...ic consumption of a particular device) or manually (clearly specified in the settings for specific devices). This allows, for example, to separate the channel for online games from the rest of the connection, minimizing lags and increasing efficiency.

— Link Aggregation. A function that allows you to combine several parallel physical communication channels into one logical one — to increase the speed and reliability of the connection. Simply put, with Link Aggregation, a device can be connected to another device not with one cable, but with two or even more at once. The increase in speed in this case occurs due to the summation of the throughput of all physical channels; however, the total speed may be less than the sum of the speeds — on the other hand, combining several relatively slow connectors is often cheaper than using equipment with a more advanced single interface. And the increase in reliability is carried out, firstly, by distributing the total load over individual physical channels, and secondly, by means of "hot" redundancy: the failure of one port or cable can reduce the speed, but does not lead to a complete disconnection, and when the channel is restored, the channel is switched on automatically.

— Bluetooth. The device supports Bluetooth wireless technology. The meaning of this function will depend on the format of the equipment operation (see "Device type"). For example, adapters with this capability allow you to supplement your PC not only with Wi-Fi, but also with Bluetooth support — thanks to this, you can get by with one adapter instead of two. And in routers and access points, this feature allows external devices to access the Internet (or local area network) over a Bluetooth connection instead of Wi-Fi. This format of work allows you to unload the Wi-Fi channel and reduce the power consumption of connected devices; this is especially important for smart home components and other IoT devices, some routers/access points expressly state that Bluetooth is intended mainly for such electronics. Other ways of using this technology, more specific, may be envisaged; however, this is rare.

— Voice assistant. Device support for a particular voice assistant. The most common options are (individually or together):
  • Amazon Alexa
  • Google Assistant
The specific functionality of these assistants can be clarified from special sources (especially since it is constantly being optimized and expanded). Here we note that in the case of Wi-Fi equipment, we are usually not talking about an assistant built into the device itself, but about improved compatibility with smartphones and other gadgets that have the corresponding assistant installed. Such functionality can be especially useful given that modern voice assistants are also used to control smart home components. Communication with such control is often carried out just through a home router or other similar equipment, and the support of such equipment for voice assistants greatly simplifies setup and expands the capabilities of the entire system.

— NAT (Network Address Translation). A function that allows Wi-Fi equipment, when working with an external network (for example, the Internet), to replace the IP addresses of all computers and other devices connected to this equipment with one common IP address. In other words, a network with such a router is seen "from the outside" as one device, with one common IP. The most popular use of NAT is to connect several subscribers to the Internet (for example, all computers and gadgets within a home or office) through one provider account. At the same time, the number of such subscribers within the network is limited only by the capabilities of the router and can be freely changed; this will not affect access to the World Wide Web (whereas without using NAT, one would have to organize a separate account for each device). NAT support is a mandatory feature for routers (see "Device type").

— Bridge mode. Possibility of operation of the equipment in the bridge mode. This mode allows you to wirelessly connect individual network segments to each other — for example, to combine two floors if it is difficult to lay a cable between them. However, communication over longer distances is also possible — in some directional access points (see "Device type"), created mainly for just such an application, the range can exceed 20 km. Actually, this mode supports most access points (both directional and conventional), but it is also popular in other types of equipment, in particular, routers.
Note that to work in bridge mode, it is best to use the same type of device — this guarantees high-quality communication in both directions. It is also worth mentioning that in addition to the two-way point-to-point mode, there is also equipment with support for multi-way bridges (“point-to-multipoint”); the availability of such a possibility should be clarified separately.

— Repeater mode. An operating mode in which the equipment only repeats the Wi-Fi signal from another device, playing the role of a repeater. The main function of this function is to expand Wi-Fi networks, providing access where the main device (for example, a router) does not reach. A classic example of repeaters is Wi-Fi amplifiers (see "Device type"), they have this mode by definition; however, it is also found in other types of Wi-Fi equipment. The exception is MESH systems that have similar specifics, but differ in the format of work. See below for more information about this format, but here we note that networks with repeaters are in many ways inferior to MESH in terms of practical capabilities. Firstly, the signals from the main equipment and from the repeater are seen as separate Wi-Fi networks, and when moving between them, subscriber devices must reconnect; this can happen automatically, but disconnections and network changes still cause inconvenience. Secondly, working through a repeater significantly reduces the speed of Wi-Fi. Thirdly, the repeater operates according to a strictly fixed, pre-established routing scheme. On the other hand, access points with a repeater function are much cheaper than MESH nodes, and the mentioned drawbacks are far from always critical.

— MESH mode. Ability to operate the device as a MESH network node. By definition, all MESH systems have this feature, but it can be provided in other types of equipment. A detailed description of networks of this type is given in the paragraph “Device type — MESH system”. Here we will briefly describe their features and the difference between this mode and the repeater mode (see above), which has a largely similar purpose.
MESH technology allows you to create a single wireless network using many separate nodes (access points) connected to each other via Wi-Fi. In this case, the so-called seamless mode of operation is implemented: the entire network is seen as a single whole, switching between access points, if necessary, occurs automatically, in such cases the connection is not broken and the user does not notice the transition to another network node at all. This is one of the key differences from using repeaters. Another difference is dynamic routing: MESH network nodes automatically determine the optimal signal traversal mode. Due to this, as well as due to some other features of this technology, the presence of "intermediaries" on the signal path practically does not affect the communication speed (unlike the same repeaters). The main disadvantage of equipment with this function can be called a relatively high cost.

— Beamforming. A technology that allows you to amplify the Wi-Fi signal in the direction where the receiving device is located (instead of broadcasting this signal in all directions or in a wide sector, as is the case in normal mode). Narrowing the radiation pattern allows you to send more power towards the receiver, thus increasing the range and communication efficiency; while the position of the receiving device is determined automatically, the user does not need to deal with additional settings. And many models of Wi-Fi equipment are capable of amplifying the signal in several directions at once (usually, several antennas are provided for this). At the same time, subscriber devices do not have to support Beamforming — communication improvement is noticeable even with the one-way use of this technology (although not as obvious as with the two-way one).
Also note that the unified Beamforming standards were officially implemented as part of the Wi-Fi 5 specification. However “beamforming” was also used in earlier versions of Wi-Fi, however, different manufacturers used different methods for implementing Beamforming, incompatible with each other. So these days, this feature is almost never found outside of Wi-Fi 5 compatible equipment.

— Firewall. A feature that allows a Wi-Fi device to control traffic passing through it. In fact, the Firewall is a set of software filters: these filters compare data packets with the specified parameters and decide whether or not to pass traffic. In this case, the processing can be carried out according to two rules: “everything that is not expressly prohibited is allowed”, or vice versa, “everything that is not expressly permitted is prohibited”. The main function of a firewall is to protect the network (or individual network segments) from unauthorized access and various attacks. In addition, this function can be used to control user activity — for example, prohibitions on access to certain Internet sites. Note that a firewall can also be implemented at the level of individual devices, but using it on a router allows you to secure the entire network at once.

CLI (Telnet). Ability to control the device via Telnet protocol. This is one of the protocols used today to remotely control network equipment; while Telnet, unlike another popular HTTP standard, does not have a graphical interface and uses only the command line. Such access is used mainly for service purposes — for debugging and changing settings in other text-based protocols (HTTP on web pages, SMTP and POP3 on mail servers, etc.); Telnet requires specialized knowledge.
