WiFi Write For Us – Every day, we use a WiFi connection. It has become an indispensable part of everyday life, so much so that according to a recent study by Devolo, 98% of the Spanish population considers the Internemesential at home, practically at the same level as water or electricity.
Ito t is possible to establish a wireless connection online in an instant so that it works without any special technical knowledge, but 93.2% of Spaniards state that they have had one problem on some occasionaHow can we find a proper solution union when the re? What is weak? What do the different standards, or what is WiFi Mesh?
Ten questions and answers related to WiFi.
What does WiFi mean?
Probably almost everyone knows the word “WiFi”. We are familiar with its fundamental principle that many electronic devices can connect to the Internet through WiFi. But what exactly is behind WiFi? When written, the abbreviation WiFi stands for Wireless Fidelity. Also, it’s surprising that modern WiFi technology isn’t that old since it started in 1999 with the IEEE 802.11a standard. Over the next 20 years, the evolution of WiFi has been very rapid.
802.11: what do the abbreviations mean?
Current WiFi standards have the names IEEE 802.11b or IEEE 802.11 b/g/n.
But what do these abbreviations mean? The “IEEE” is quick to explain: it stands for the Institute of Electrical and Electronics Engineers, which defines the standards. The first WiFi allows transmission allowing transmission speeds of 2 Mbps.
Network names with individual letters indicate technical advances. The most important steps:
- IEEE 802.11b: Transmission speeds of up to 11 Mbps over the 2.4 GHz band
• IEEE 802.11a: Transmission speeds of up to 54 Mbps over the 5 GHz band
• IEEE 802.11g: Further development of the “b” standard with transmission speeds of up to 54 Mbps
• IEEE 802.11n: simultaneous use of the 2.4 and 5 GHz bands for transmission speeds of up to 600 Mbps
• IEEE 802.11ac: further development of the “n” standard with transmission speeds of up to 6,933 Mbps
• IEEE 802.11ax: Further development of the “ac” standard with transmission speeds of up to 9,600 Mbps
And what are WiFi 5 or WiFi 6?
The name of WiFi technical standards is unclear and can be unnecessarily complicated for end users. Therefore, in recent years an alternative simplified vocabulary has been established. WiFi 5 is arguably the actual name for the IEEE 802.11ac standard, and WiFi 6 is another name for IEEE 802.11ax.
Are the WiFi stand a much care generally other?
Much care is generally paid to the backward compatibility of WiFi standards. Therefore, you would have to use primitive devices at home to cause problems that could prevent connections altogether. In such a case, it would be sensible to renew them, if only for sex shows. However, this also shows that such issues can occur if old devices are used. In case of doubt, the corresponding information can be found by examining the documentation. However, in most cases, WiFi-certified devices are easily compatible. For example, the latest WiFi 6 standard is backwards compatible with 802.11a, b, g, n, and ac. It should be noted, however,
What is the difference between 2.4GHz and 5GHz?
WiFi communication can occur via the 2.4 GHz and 5 GHz frequency bands. But what is the real meaning of this, and what are the advantages of each solution? This question cannot be answered in general terms since neither frequency band is superior. Instead, the decision depends on specific conditions. For example, the 2.4 GHz frequency band has a broader range but is also more susceptible to problems, especially in densely populated areas. The 5GHz band has a lower degree but allows for slightly higher bandwidths and is fewer susceptfewer devices use it because fewer devices use it.
Therefore, connections through the 5 GHz frequency with higher data throughput higher with higher data throughput, streaming s, series or movies. For its part, the 2.4 GHz frequency band is more suitable to guarantee an essential online connection to a certain extent, for example, to surf the Internet or consume social networks.
How secure is WiFi?
With this question, it is usually necessary to distinguish whether a wireless LAN (private or public network) is involved. In general, users should still be careful with freely accessible public networks. Vulnerabilities can never be excluded entirely, especially in the case of unencrypted wireless LANs; if possible, it is recommended that applications with sensitive information are not used on these networks; this includes, for example, private online banking.
Of course, in their wireless LAN, users are personally responsible for the level of security required and are quick to come across the terms WEP, WPA, WPA2, and WPA3. These represent different encryption methods. WEP (Wired Equivalent Privacy), the oldest form, is now considered insecure and is no longer up to date. This also applies to the first version of WPA (WiFi Protected Access).
WPA2 and WPA3 are the latest and most secure encryption methods for home wireless LANs. WPA3 provides a slightly higher level of security and makes it more convenient to set up a wireless LAN. But since there’s still a long way to go before every device supports WPA3, WPA2 is also an excellent option for WiFi security. With both variants, however, the natural first step in strengthening security is to choose a suitably strong password!
What leads to poor WiFi reception?
WiFi connections in private homes have a large number of natural enemies: walls and ceilings, as well as other electronic devices. These devices include, for example, microwave ovens, baby monitors, or wireless computer accessories. Furniture, houseplants, or water can create potential problems, including water pipes, underfloor heating systems, or even flower vases. However, this does not mean you must empty the house to ensure good WiFi reception.
Choosing where to place the router can lead to significant improvements if problems arise—for example, not putting it inside cabinets and setting it as centrally as possible. If this is not possible or the house is too big, technical devices can be used to increase the range of WiFi.
How can the WiFi network be extended?
In many homes, there are too many deficits in WiFi performance because the router reaches its limits. In many cases, the reason for these deficits is not the hardware itself, but the problem is that the Internet connection comes from a place in the apartment or house that is often far from the areas where it is needed. The good news is that WiFi quality can be improved in these situations, too, without any complex or expensive structural measures.
WiFi repeaters receive the existing signal from the router and “extend” it, resulting in better coverage.
However, it is not surprising that this type of extension over long distances is also prone to problems. As the distance increases, the WiFi signal received by the repeater becomes weaker and weaker. Instead of relying on multiple repeaters being daisy-chained, users should turn to solutions known as Powerline. These solutions consist of practical adapters that house electrical wiring and power outlets.
Therefore, the adapters use the house’s electrical wiring to transmit data, and the Powerline connection is not slowed down by walls or ceilings and is suitable for bridging longer distances. Also convenient is that, depending on the chosen Powerline model, the online connection is available via LAN cable and wireless LAN at the destination.
Does 4K streaming work over WiFi?
The number of streaming services is continuously increasing, and more people prefer watching movies and series online instead of on traditional television channels. However, bandwidth requirements are also growing, mainly due to the trend towards 4K resolution. The good news is that a bandwidth of at least 15-25 Mbps is recommended for 4K content, a requirement that modern WiFi technology easily meets. This means nothing stops you from kicking back with an evening of wireless cinema. Provided, of course, that the Internet connection provides sufficient bandwidth and that the WiFi signal reaches the entertainment corner without any problem.
What is WiFi Mesh?
To some extent, Mesh WiFi is considered an intelligent home network in which multiple WiFi access points work through close interconnections. What effect does this have? For example, a mobile device always connects to the optimal access path where many devices are connected. The point is that the mesh network manages this connection’s controloving to WiFi Mesh can be worthwhile, especially in large homes with many connected devices. In traditional WiFi setups, however, devices typically “stick” to an existing access point connection, even if a better relationship is closer. This becomes evident, for example, every time you move around the house during a video call. The central control of data transmission in Mesh systems also enables other clever extras, such as “Band Steering” for automaticness” (“equity of connection”).
