Comparison Asus RT-BE92U vs Asus RT-BE86U

Standard Wi-Fi frequency bands supported by the device.

This parameter is directly related to the Wi-Fi standards (see above) that the equipment complies with. At the same time, there are standards that cover several bands at once (such as Wi-Fi 4 and Wi-Fi 6), and not every device compatible with them supports all these bands at once; so in such cases this point should be clarified separately. In addition, the frequencies commonly used nowadays have common features, here they are:

— 2.4 GHz. Classic range: used in the earliest Wi-Fi standards, and supported by many modern versions. Therefore, quite a lot of Wi-Fi equipment still works only at 2.4 GHz(although exceptions are increasingly common). The main advantages of such equipment are simplicity, low cost, and compatibility even with frankly outdated wireless devices. On the other hand, the 2.4 GHz band is extremely busy: in addition to numerous Wi-Fi devices, it is also used by Bluetooth modules and some other types of electronics. This may degrade the quality and speed of the connection.

— 5 GHz. A band introduced to overcome the shortcomings of 2.4 GHz — in particular, to offload communication channels and separate Wi-Fi from other wireless technologies. In addition, increasing the frequency allowed to increase the communication speed. 5 GHz is used as one of the operating frequencies in the Wi-Fi 4 and Wi-Fi 6 standards (see above) and as the only...one in Wi-Fi 5. So you can find devices on the market that operate only at 5 GHz, but more widespread received equipment with multiple bands, where this frequency is only one of the supported.

— 6 GHz. An unloaded frequency introduced into use since the Wi-Fi 6E generation. The new range provides the ability to simultaneously operate numerous client devices at high speed with a minimum amount of interference and delays in signal transmission. At the moment, this is the freest, widest and fastest Wi-Fi range. However, in some regions, the 6 GHz frequency remains unavailable due to the occupancy of the band by means of military, fixed or radio relay wireless communications.

— 60 GHz. Range implemented in the WiGig standard; today it is used only in it, and as the only one. A significant increase in frequency compared to the more common 2.4 GHz and 5 GHz options has a positive effect on the quality of communication. So, with the same theoretical maximum as that of Wi-Fi 6 (10 Gbps), the WiGig standard gives a higher actual data exchange rate, as well as fewer delays and lags; this is especially important in games and some specific tasks. The downside of these advantages is a small communication range: even when using Beamforming (see "Functions and Capabilities"), it does not exceed 10 m in open space, and an obstacle like a wall can become insurmountable for a 60 GHz channel. Therefore, in Wi-Fi equipment, this frequency is found mainly among rather specific devices — access points (including directional ones), which are designed to connect individual network segments in bridge mode (see ibid.). It is this mode of use that is one of the most optimal, given the properties of this range. However, 60 GHz support is also increasingly found in consumer gadgets (smartphones, laptops), so routers are also being released for this frequency.

— Natural frequency. In rare cases, the operation of Wi-Fi equipment is possible at natural frequencies that do not fall under the standard generally accepted values. Such devices are mainly used to build point-to-point and point-to-multipoint radio bridges. Their advantages include low frequency noise from standard Wi-Fi networks, and, as a result, increased communication range. It is worth noting that it is impossible to connect directly to such devices from a laptop or smartphone. It is also necessary to take into account the legislative aspect, since in each country the use of frequencies is regulated differently.

The number of wireless bands and channels supported by the router. Specified only for models that work with more than one range.

— Dual-band (2.4 GHz and 5 GHz). Devices that simultaneously support two popular communication bands — 2.4 GHz and 5 GHz — in the "one communication channel per band" format. This ensures compatibility with most Wi-Fi standards (see above), and in some cases also has a positive effect on the quality of communication. For example, a Wi-Fi adapter (see "Device Type") with this feature may provide the ability to evaluate the load on both bands and automatically select the less loaded one.

— Three-channel (2.4 GHz and 5 GHz in 2 channels). An improved version of the dual-band operation format: in the 5 GHz band, communication is carried out on two channels. This allows, for example, to “raise” three wireless connection channels on one router at once (three visible networks in the list of wireless networks) and achieve even higher throughput. The advantages of this format are especially noticeable when the router works simultaneously with several wireless devices.

— Tri-band (2.4 GHz, 5 GHz, 60 GHz). The most "omnivorous" type of modern Wi-Fi equipment, compatible with all popular standards — from the outdated 802.11 b / g to the relatively new 802.11 ad. Also, the abundance of ranges contributes to an increas...e in speed, especially when working with multi-range devices.

The maximum speed supported by the device when communicating wirelessly in the 5 GHz band.

This range is used in Wi-Fi 4, Wi-Fi 6 and Wi-Fi 6E as one of the available bands, in Wi-Fi 5 as the only one (see "Wi-Fi Standards"). The maximum speed is specified in the specifications in order to indicate the real capabilities of specific equipment - they can be noticeably more modest than the general capabilities of the standard. Also, in fact, it all depends on the generation of Wi-Fi. For example, devices with Wi-Fi 5 support can theoretically deliver up to 6928 Mbit (using eight antennas), with Wi-Fi 6 support up to 9607 Mbit (using the same eight spatial streams). The maximum possible communication speed is achieved under certain conditions, and not every model of Wi-Fi equipment fully satisfies them. Specific figures are conditionally divided into several groups: the value up to 500 Mbit is rather modest, many devices support speeds in the range of 500 - 1000 Mbit, indicators of 1 - 2 Gbps can be attributed to the average, and the most advanced models in class provide a data exchange rate of over 2 Gbps.

The maximum speed supported by the device when communicating wirelessly in the 6 GHz band.

- 160 MHz. The presence of a bandwidth of 160 MHz increases the throughput for data transmission and allows it to approach the maximum theoretical speed.

- 320 MHz. The bandwidth of 320 MHz was introduced in the Wi-Fi 7 standard (see the corresponding paragraph). It provides a significant increase in the speed of data exchange - twice as much compared to the width of the wireless channel of 160 MHz.

The number of USB 2.0 ports provided in the design of the device.

USB in this case plays the role of a universal interface for connecting peripheral devices to the router. The specific USB devices supported and how they are used may vary. Examples include working with a flash drive that plays the role of a drive for working in FTP or file server mode (see "Functions / Capabilities"), connecting to a printer in print server mode(see ibid), connecting a 3G modem (See "Data input (WAN-port)"), etc.

Specifically, USB 2.0 allows you to transfer data at speeds up to 480 Mbps. This is noticeably less than that of more advanced standards (starting with USB 3.2 gen1 described below), and the power supply of such connectors is low. However, even such characteristics are often quite enough, taking into account the specifics of the use of Wi-Fi devices. In addition, peripherals for newer versions can also be connected to the USB 2.0 port — the main thing is that the power supply is enough. Therefore, although this standard is considered obsolete, it is still widely used in modern wireless equipment. There are even models that provide 2 or even more USB 2.0 ports; this allows you to simultaneously use several external devices at once — for example, a 3G modem and a USB flash drive.

— External. Outdoor antennas tend to be larger than indoor antennas, and they usually have swivel mounts that allow the rod to be placed in the optimal position, regardless of the position of the device itself. All this has a positive effect on signal strength. In addition, there are removable external antennas — if desired, they can be replaced with more powerful ones. The main disadvantage of this option can be called bulkiness.

— Internal. Antennas located inside the case are considered less advanced than external ones. In most cases, they are smaller, and the performance depends on the position of the device (although many manufacturers use technologies to compensate for this effect). At the same time, equipment with internal antennas has a neat appearance without unnecessary protruding parts.

— External / internal. The presence in the device at once of both types of antennas described above (in this case, there may be more than one of those and others). The presence of several antennas improves the quality of communication, but if they are all external, the device may turn out to be too bulky. Therefore, in some models of routers, a compromise is used: part of the antennas is hidden in the case, which has a positive effect on compactness and appearance.
