Number of antennas

The total number of antennas (of all types — see below) provided in the design of the device.

In modern Wi-Fi equipment, this indicator can be different: in addition to the simplest devices with 1 antenna, there are models where this number is 2, 3, 4 and even more. The point of using multiple antennas is twofold. Firstly, if there are several external devices per antenna, they have to share the bandwidth among themselves, and the actual communication speed for each subscriber drops accordingly. Secondly, such a design may also be required when communicating with one external device — to work with MU-MIMO technology (see below), which allows you to fully realize the capabilities of modern Wi-Fi standards.

Anyway, more antennas, usually, means a more advanced and functional device. On the other hand, this parameter significantly affects the cost; so specifically looking for equipment with numerous antennas makes sense mainly when the speed and stability of communication are critical.

Note that antennas intended for mobile communications may also be considered in this clause. So when choosing a model with support for mobile networks, it's ok to clarify this point.

2.4 / 5 GHz antennas

The total number of antennas in the router that can operate on both 5 GHz and 2.4 GHz frequencies. For details about the number of antennas, see "Total antennas", about the range — "Frequency range".

Operating temperature

Ambient air temperature at which the device is guaranteed to remain operational.

All modern Wi-Fi equipment can easily endure the conditions typical for use in apartments, offices, etc. So it makes sense to pay attention to this parameter mainly when choosing a model for outdoor installation (see above) or indoors , where the conditions are not very different from those outside. At the same time, the upper temperature limit is usually quite high, and even in the heat there are usually no problems with operation (of course, if the device is not installed in direct sunlight — which is not recommended anyway). But the lower temperature threshold can be different, not all "street" equipment is designed for frost. However, among frost-resistant models there are solutions where the minimum operating temperature is -10 °C and below, and sometimes even -40 °C and below.
