In simple words: 5 important characteristics of a router

Despite the fact that the Internet can be safely included in the list of basic needs of a modern person, it is good

understand the characteristics of the networkequipment is far from all users. In this article, we will consider several basic parameters of routers (routers), the understanding of which will simplify your choice.

Frequency range

The frequency range is a kind of aerialthe road along which data is transmitted from the router to the devices. According to the number of supported ranges, routers are divided into single, dual and tri-band.

Single-band - devices that work only in2.4 GHz band. Continuing the parallel with the roads, this is the classic transport system of the city. And, as in any city, the problem of traffic jams is inevitable, in this case the bandwidth drops due to the low signal transmission speed and high density of home or office networks.

Dual band routers operate in 2.4 bandsand 5 GHz is the most convenient scenario for the user, combining, so to speak, the advantages of a conventional road system and high-speed highways. The 2.4 GHz band should be used for tasks that do not require high data rates, such as email or Internet surfing. And games, streaming and other heavy network tasks should be moved to the 5 GHz band.

Tri-band router models canboast an additional 5 GHz band, which is used for gaming devices or for exchanging data between nodes of mesh networks - such as dedicated public transport lanes, albeit with maximum speeds.

Wi-Fi standard

Wi-Fi standard means a setcapabilities used in data transmission. Here we are talking about speeds, and about additional chips for smart home devices, which have been added to the most relevant standard today. The following Wi-Fi standards are now widely used:
- Wi-Fi 4 (802.11n);
- Wi-Fi 5 (802.11ac);
- Wi-Fi 6 (802.11ax).

The first standard from the list (Wi-Fi 4) is already going intothe past, and the latter (Wi-Fi 6) is only gaining popularity. So it makes sense to choose devices with an eye to the future - gadgets with support for the latest Wi-Fi standard will still appear in your house, and content and software producers are trying to squeeze everything out of the bandwidth of your home network.

Mesh technology support

The increase in housing and office space has led tothat one wireless router may not be enough. Then the signal weakens, then the speed drops, then some parts of the room behind the load-bearing walls are not captured at all. And to add that there are many devices connected - we get signal drops and disgruntled users.

The solution may be to use routers withsupport for mesh networks. These networks combine multiple wireless devices to expand Wi-Fi coverage and distribute the load from a large number of client devices. But perhaps the biggest advantage of mesh is its support for “seamless roaming” between nodes. The user within the coverage area of ​​the mesh network is automatically “transferred” from node to node without interrupting data transmission.
ASUS devices include both mesh systems with several bundled devices and conventional routers supporting AiMesh technology, which can be combined into a single mesh system.

Antennas

Most often, when the word “router” is used, the imagination drawsA “slinky” box in the corner. But now the presence or absence of external antennas is more a matter of appearance and personal preference of the user. There are quite a few wireless routers with built-in antennas that work very well in modern apartments and houses. And in general, the design issue has recently been taken up close, take at least RT-AX82U or RT-AX89X gaming routers or stylish discreet models ASUS ZenWiFi XT8 or ASUS ZenWiFi XD4.

Ports

It is also important to understand that in addition to distributing Wi-Fithe router can perform other functions for which it is necessary to connect additional devices. The presence of 100 Mbps or 1 Gbps Ethernet ports, and in the top models - 2.5 Gbps ports (RT-AX86U, GT-AX11000) or even 10 Gbps (RT-AX89X), allows you to use the maximum by speed wired connection. The USB port can be used to create a home NAS or home print server.
