Comparison LAVA MF802S vs Huawei EC5805

Wi-Fi connection speeds, more precisely—the Wi-Fi standards supported by a modem with the corresponding capabilities (see “Type” and “Connection”).

— Wi-Fi 3 (802.11g). A further development of the Wi-Fi 1 (802.11b) standard, designed primarily to increase connection throughput (2.4 GHz) and introduced in 2003. 802.11g equipment is fully backward compatible with 802.11b, so even the simplest modern Wi-Fi devices support both standards.

— Wi-Fi 4 (802.11n). A Wi-Fi standard that further develops the formats described above—in particular, by adding support for MIMO technology (distributing input and output among multiple antennas). Introduced in 2009. The primary operating frequency is 2.4 GHz, although devices with an additional 5 GHz band are also available.

— Wi-Fi 5 (802.11aс). Based on 802.11n and introduced at the end of 2013. The main improvements involved increasing the number of streams on the second frequency (5 GHz) and implementing more advanced MIMO and modulation standards, which accordingly increased throughput.

— Wi-Fi 6 (802.11ax). Wi-Fi 6 distributes internet using the modern 802.11ax standard in the 2.4 and 5 GHz bands, handling large numbers of connected devices more effectively. Such a modem is especially convenient where smartphones, laptops, a TV, and smart devices use the network simultaneously, because Wi-Fi 6 distributes traffic more efficiently a...nd reduces latency on a busy network. Compared with Wi-Fi 5, the difference is usually felt not so much in “peak” speed as in more stable operation during streaming, video calls, and online gaming.

— Wi-Fi 6E (802.11ax). Essentially the same Wi-Fi 6, but with the addition of the 6 GHz band, making the connection more stable, especially in congested areas. In practice, this is particularly useful in an apartment building with many neighboring networks. But the main point is that the advantage of Wi-Fi 6E is only realized on devices that also support 6 GHz. It is precisely this frequency that makes it possible to allocate a separate channel with the fewest interferences from third-party devices.

— Wi-Fi 7 (802.11be). A step beyond Wi-Fi 6E: it provides even higher speeds, lower latency, and more stable network performance under load. Its key advantages over the previous version are associated with channels up to 320 MHz and Multi-Link Operation, allowing a device to use multiple bands simultaneously rather than just one. In practice, this is especially useful if the modem is to replace the main home router and distribute fast 5G to a laptop, gaming PC, TV with 4K/8K content, NAS, and other demanding equipment at the same time. In other words, Wi-Fi 7 is intended for cases where you need not just fast Wi-Fi, but significant headroom in speed and responsiveness for the future.

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.
