Wi-Fi routers that use only one frequency, usually that of 2. In fact, these routers preferably use the 2. In most cases you can still turn off the 5 GHz frequency and turn it on only when you need to support a higher data traffic.
These exploit the usual 2. Considering what we have already said above, the use of two high-frequency bands gives these dongles high traffic capacity and makes them suitable for very intense bandwidth use. Currently, there are several wireless connectivity standards. A WiFi dongle can support several at the same time, and a combination of the characteristics of each standard can result in very sophisticated overall performance.
In general, the following are the characteristics of current standards, from the oldest to the most recent:. Furthermore, starting from This allows the transmission to be more stable, in relation to domestic interference and obstacles encountered by the radio wave.
A further innovation was then introduced by the ac standard, which implements MU-MIMO technology multiple-users multiple-input multiple-output. The MU-MIMO technology allows the simultaneous connection of multiple terminals, without the need to alternate the transmission from one to the other. In order for the wireless connection to be accessible only to authorized persons and devices, it must be protected against unauthorized access.
The username and password that you enter when you first connect to the router are not sufficient; the radio signal must be encrypted too.
Over the years, several encryptions have followed one another, gradually more secure: the oldest, now obsolete and abandoned, is WEP, followed by WPA and finally by WPA2. You will not find any WiFi router after that does not have a WPA2 security key, so you can rest be assured that any recent model will be perfectly updated from this point of view. Firewall is another security feature which you can find and can activate on practically all WiFi dongles.
This allows you to monitor incoming and outgoing data traffic, and to block any access to the home network deemed potentially dangerous. WiFi dongles can be equipped with both internal and external antennas. The latter solution, in particular, can be useful if the router signal, in the place where you intend to use the key, is not particularly strong. The external antennas can be fixed or removable and directional or omni-directional. The power of the antennas is expressed in dBi, i. In general the higher the dBi gain, the better the signal reception, however its quality can be influenced by many other parameters.
The brand of a WiFi dongle can be important for a few reasons. Firstly, the major manufacturers of these devices like TP-Link, Huawei and NetGear, offer their customers much more responsive and easy-to-reach assistance and support than lesser-known brands.
Secondly, they are also able to offer the best products, updated with the latest technologies and with the highest performance. This does not mean that other manufacturers market products that work worse, but simply that in case of failure it will be more difficult to obtain repair or replacement under warranty.
WiFi dongles are starting to become popular thanks to their significant advantages. For this reason, more and more people are investing in WiFi dongles. If you want to know in detail what kind of advantages they offer, read on.
