Comparison LAVA MF802S vs Huawei EC5805

Wi-Fi generation and frequency bands over which the modem shares mobile internet. The 2.4 GHz frequency provides greater range and penetrates walls better, 5 GHz usually offers higher speeds and less interference, while 6 GHz provides additional free channels but requires compatible devices and penetrates obstacles less effectively. At the same time, newer Wi-Fi does not speed up the mobile network itself: the final speed also depends on the modem’s capabilities, the operator’s coverage, and the connected equipment.

— Wi-Fi 3 (802.11g). An outdated standard operating in the 2.4 GHz band with a theoretical speed of up to 54 Mbps. Suitable for basic internet access, but it can noticeably limit the speed of a modern LTE connection.

— Wi-Fi 4 (2.4 GHz). A widespread 802.11n standard with good range and broad compatibility. Suitable for everyday use, although the single 2.4 GHz band is more susceptible to interference and may limit the capabilities of fast LTE or 5G.

— Wi-Fi 5 (2.4 + 5 GHz). A dual-band option that allows 2.4 GHz to be used for better coverage or 5 GHz for higher speeds and less congested spectrum. This is a balanced solution for home use, travel, and connecting multiple devices simultaneously.

— Wi-Fi 6 (2.4 + 5 GHz). A modern 802.11ax standard that distributes traffic among connected devices more efficiently and operates...more stably under load. Well suited for sharing fast LTE or 5G with several smartphones, laptops, and other equipment.

— Wi-Fi 6 (2.4 GHz). A version of Wi-Fi 6 operating exclusively on the 2.4 GHz frequency. It combines modern traffic management mechanisms with good coverage range, but falls short of dual-band models in speed and resistance to interference.

— Wi-Fi 6E (2.4 + 5 + 6 GHz). A tri-band evolution of Wi-Fi 6 with the additional 6 GHz frequency, where there is usually less interference and more free channels are available. The benefits of the new band are realized only with compatible equipment, while other devices connect via 2.4 or 5 GHz.

— Wi-Fi 7 (2.4 + 5 GHz). The latest generation of wireless communication without support for the 6 GHz band. It provides more efficient data transmission and can use several bands simultaneously, but does not support the widest 320 MHz channels available to tri-band models.

— Wi-Fi 7 (2.4 + 5 + 6 GHz). A tri-band version of Wi-Fi 7 designed for maximum throughput and minimal latency. When supported by the modem and connected device, it can use several bands simultaneously and channels up to 320 MHz wide in the 6 GHz frequency.

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.

The presence of a slot for an R-UIM card in the modem design. The purpose of such cards is similar to the SIM cards described above, but they are used in networks based on CDMA (and, accordingly, in modems with EV-DO support, see "Transmission Technologies"). Note that, unlike devices for GSM and UMTS networks, for CDMA modems a slot for this type of card is not a mandatory element of equipment — many such devices are tied to the network by changing the firmware, which is why operators of such communication may not use R-UIM at all. Therefore, although in general the use of cards is simpler and more convenient for the user than flashing, however, the choice of the presence or absence of an R-UIM slot depends on the requirements of the network with which the modem is planned to be used.

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).

The maximum operating time of the modem with battery power (see "Power") on a single charge in Internet browsing mode. Such power is typical for Wi-Fi routers, therefore, usually, Internet browsing is supposed to provide access to the World Wide Web for an external Wi-Fi device.

This spec is the main indicator of battery life for any battery-powered modem, because it describes the time of using it for its main purpose without recharging. At the same time, you should know that this indicator is measured under certain "perfect" conditions; the actual operating time depends on a number of factors, including the intensity of browsing, the amount of data transferred, the number of connected devices and the distance to them, the cellular network signal strength, etc. Therefore, in fact, the battery life of the modem may be somewhat lower. Nevertheless, it is quite possible to compare different models with each other according to the operating time stated in the specs.
