Definition And Mode Of Operation Of LiFi

LiFi is a wireless communication system that uses visible light. Unlike Wi-Fi powered by the electromagnetic spectrum, LiFi employs the optical range. It works by encoding and transmitting data through the transformation of the amplitude of light sources, respecting the protocol.

In addition, by using an LED bulb several times, information is transferred by creating a random binary code. The rapid changes in the sequences make it possible to send all types of data at a higher speed than Wi-Fi. Do not hesitate to adopt LiFi Technology: the Internet through light.

The Different Advantages Of LiFi

Light Fidelity is a technology with multiple benefits. It’s about :

• The multiplication of access points;
• Reducing expenses;
• Reinforcement of security;
• A connection with a more stable and high speed.

LED bulbs are nowadays widely used by many households and individuals, which contributes to the multiplication of potential access points. As for the reduction of expenses, it is possible to carry out the equitable distribution of the installation costs and optimize the exploitation of the lighting. Regarding the security system, the light waves serving as the basis for LiFi cannot go beyond your private space. For this purpose, the risk of hacking is almost impossible.

Finally, LiFi is much faster than Wi-Fi. In this sense, Oledcomm presented it at the beginning of 2020 as a solution capable of reaching a speed of 1 Gb/s. However, his device forces the user to remain close to a light source in operation. In addition, its diffusion is minimal, and interference with other light sources such as sunlight can hinder its process.

The First Experiences Of LiFi

Since its launch, LiFi has attracted many individuals and communities. In, it has been installed in many sectors. As part of a temporary exhibition in 2015, anyone wishing to discover the playing card museum could access the visitor guide via a tablet equipped with a LiFi key. In addition, the train stations are equipped with luminous GPS. In addition to these first uses, Air joined forces in November 2019 to launch the project to install LiFi in planes to allow passengers to enjoy a good connection during their flight.

LiFi And The 5G Network

LiFi technology and 5G network can complement each other. In Germany, some companies such as Vodafone and Signify have taken the initiative to combine the power of 5G with LiFi to offer a secure broadband connection. On the other hand, Huawei also presented a project within the framework of the use of 5G in addition to LiFi, more specifically in the field of health.

What Is A Wi-Fi Router

A Wi-Fi router is a device that uses a modem to shop for Internet streams that they automatically transform and transmit (perhaps through an Ethernet cable) as a wireless signal to allow the user to have good internet access. It can provide a high-speed connection even remotely thanks to the WLAN network it integrates. Devices don’t necessarily need to use a cable before connecting to them. The Wi-Fi router, since its appearance, continues to modernize. This is the reason why it should be changed after an average period of 24 months of intensive use to have an Internet connection adapted to its time and needs.

What Are The Characteristics Of A Wi-Fi Router

They are decisive in choosing the best Wi-Fi router. These include performance, quality of service for the use of specific software or applications, network coverage, number of bands, data security capacity, transmission speed, the appropriate standard. , etc. As you can see, the list is long. Also, the performance of Wi-Fi routers depends on technological innovations and the brand. No need to remember that the cutting edge of technology also involves the cost.

How Does A Wi-Fi Router Work

The Wi-Fi router allows user quality access to the Internet network through devices. How does it work? The flows are invisible to the naked eye. It’s all about the transmission and reception of waves between the Wi-Fi router and the connected tools. The router has an IP address and the connected tools have a MAC address. The Wi-Fi router, therefore, uses the MAC address of the devices to send them the necessary data. However, it should be noted that each MAC address is unique in the same way as the IP addresses.

What Are The Advantages Of A Wi-Fi Router

Whether for professional or home use, the Wi-Fi router has several advantages. Among other things, it allows:

• To have an optimized broadband connection.
• To simplify the transfer and sharing of data.
• To raise the level of security of the wireless network and of the tools to be connected by ricochet.
• To stabilize and regulate the Internet connection.
• To offer parents the possibility of having control over the use made of it by children in domestic use.

What Is MU-MIMO Technology

The usual thing is that in our router there are many devices connected. Each user has several connected types of equipment, such as a mobile, laptop, tablets, etc. There may also be televisions and any other equipment from what is known as the Internet of Things.

The problem is that when we connect with many devices at the same time, there can be problems. This results in a loss of speed, cuts and less stability. Now, this will also depend on the type of router we have and the technology it uses. That’s where MU-MIMO technology comes in.

MU-MIMO technology is also known as multiple users, multiple inputs and output technology. This allows a router to connect with multiple devices at the same time simultaneously. It can reduce the waiting time of the connected devices to be able to receive the wireless signal in a better way. This way, we can improve wireless speed and avoid problems that affect stability and quality.

This technology is especially suitable for those users who have several devices connected at the same time via Wi-Fi. Thus we will avoid problems as we have commented and we will be able to connect with more significant guarantees to the Internet wirelessly.

Device Compatibility

When this technology emerged, it was only present in some routers and access points. However, with time, it has also been incorporated into end devices, which, after all, is what users use the most to navigate.

Keep in mind that not all routers have this technology available, as we have mentioned. However, most modern ones it is expected that they do have it. We already know that today there are many computers that we connect wirelessly, and this makes it necessary to have routers capable of supporting a large load.

Compatibility with other devices must also be taken into account. First of all, it should be mentioned that any device that has Wi-Fi connectivity will be able to connect with a router with these characteristics. However, it will have to have MU-MIMO technology to be able to take advantage of the advantages and not have that loss of speed or stability that we have mentioned when we connect with several computers at the same time.

More Devices Connected Wirelessly

Over time we have been incorporating more and more devices into our day today. Currently, it is normal for each household to have at least one mobile phone for each member. You may also each have a laptop and perhaps a desktop computer in common.

But in addition to that, we must add possible tablets, ebooks and other devices of what is known as the Internet of Things. Here the range is extensive, and the truth is that there will be more and more. For example, televisions, light bulbs, video players. Everything indicates that in the coming years, the figure will multiply.

This means that logically we have to have a router capable of supporting all this load. It does not matter the Internet speed that we have contracted if later, there are many devices connected at the same time, and the router is not capable of managing all the requests.

This is where MU-MIMO technology comes in, allowing multiple devices to be connected at the same time and reducing connection speed, quality and stability issues. It is, therefore, essential to have a router that has this capability. Thus we will avoid problems, and we can navigate with more significant guarantees.

In short, MU-MIMO technology is an extra that offers our router the possibility of managing multiple connections more efficiently and always maintaining Internet speed. In the end, having a good connection is essential for users, and it is essential to avoid problems.

Differences Between 2.4 or 5 GHz Wi-Fi

Modern routers can offer 2.4 GHz or 5 GHz Wi-Fi Internet. Each option has its advantages and disadvantages. When using a mobile, tablet or any similar equipment, we can choose one or another option. Of course, as long as it is compatible.

If we talk about the general points, we can say that the 2.4 GHz band allows a greater distance from the router. That is, we can connect further without suffering so many problems. Now the speed is lower. In contrast, the 5 GHz band allows for much higher rates. It is ideal if we want to navigate faster and make the most of the connection we have contracted. Instead, it is much more sensitive to distance.

Therefore we can say that the 5 GHz band will be used when we connect near the router and want the maximum speed, while the 2.4 GHz band will be when we are located further away, there are walls or walls, and we need the best stability without matter both speed.

How To Know The Mobile Has 5 GHz Wi-Fi

More and more mobile devices have dual-band. This means that we can connect to the 2.4 GHz band and the 5 GHz band. It is the ideal way to make the most of the connection depending on the conditions in which we find ourselves. We have several ways to know if our mobile is dual-band. This is very interesting to be able to choose better which network to connect to. There will be times when we can only use 2.4 GHz because that access point or router does not have 5 GHz, while at other times we can choose between both.

Search Networks

A straightforward and visible way is to search for networks. The usual thing is that in the name of the system we put in it is 5 GHz or not, and even depending on the model, the device itself can notify us. It is not always available, but it is in many cases.

To do this, on Android, we have to go to Settings, enter Connections and go to Wi-Fi. This may vary depending on the version we have installed, but it is very similar in all cases. When we are in Wi-Fi, we will search for networks, and the list of all the ones we have available around us will appear.

Do we see any network that is 5 GHz? Usually, something like this of the type NombreWiFi_5G comes. This could give us a clue, although that name has also been modified. Sometimes our mobile shows us a small circular icon where 5G appears next to the network. In this way, we will have more guarantees that indeed that network is 5 GHz and therefore our device is dual-band.

5 GHz Tester App

An alternative to seeing if the mobile is compatible with 5 GHz is to install an application that tells us. It is about 5 GHz Tester. It is free for Android. To install it we have to go to the official store. As we always say, we recommend installing these types of tools ever from reliable sources to avoid problems that could compromise our security. The application is straightforward. Once we have it installed, we have to run it and start the test (Check). It will automatically tell us if the mobile is compatible or not with 5 GHz Wi-Fi networks.

That simple we can use the 5 GHz Tester application to know if our mobile is dual-band or not. We can choose which band to connect to whenever possible. In short, by following these simple steps, we will be able to know if we have the option of using the 2.4 GHz band or the 5 GHz band. As we have seen in summary, each of the two options has its positive and negative points. You will have to choose which one to use according to the conditions in which we find ourselves at any given time.

With Hotspot 2.0, abbreviated HS2, there is a standard of the Wi-Fi Alliance and the Wireless Broadband Alliance. Alternative terms used for Hotspot 2.0 are Next Generation Hotspot (NGH) or Wi-Fi Certified Passpoint. The standard aims to enable mobile devices such as smartphones, tablets, or laptops to automatically connect to a Wi-Fi hotspot within range and authenticate themselves. The user does not have to be active and enter access data. The authentication can, for example, take place based on the SIM card data or certificate-based.

Enterprise-class WPA2 (Wi-Fi Protected Access 2) is used as encryption technology in a Hotspot 2.0 network. Hotspot 2.0 is an extension of the IEEE standard 802.11u, published in 2011.

Possible areas of application for Hotspot 2.0 are traffic offloading and automatic roaming between different WLAN operators networks. With traffic offloading, data traffic from cellular networks can be automatically shifted to access systems with alternative wireless network technology such as a Wi-Fi network. Traffic offloading prevents traffic jams in the cellular network and improves network coverage for users. Numerous hotspot solutions, mobile devices, and operating systems such as iOS, Android, macOS, and Windows are compatible with Hotspot 2.0.

Basic Functional Principle Of Hotspot 2.0

To automatically switch to an available Hotspot 2.0 compatible WLAN, the standard defines two phases that generally take place one after the other. These two phases are:

1. Discovery an Selection (finding and selecting)
2. Authentication

Finding and choosing a compatible hotspot is implemented using so-called beacons. They are exchanged between the client (mobile device) and the access point (hotspot). The client receives a lot of information about the hotspot and the network via the beacons. Transferred information is, for example:

• The signal strength of the hotspot
• SSID (Service Set Identifier)
• Network type
• Support of the IEEE 802.11u standard

The client and hotspot exchange further information via the GAS (Generic Advertisement Service) and ANQP (Access Network Query Protocol) protocols. The protocols work on layer 2 of the ISO / OSI layer model and ensure information transmission about supported authentication methods or roaming partners.

After the “Discovery a Selection” phase, the actual authentication of the client takes place. Hotspot 2.0 allows different authentication methods. The methods are based on WPA2 Enterprise Security and are selected via the Extensible Authorization Protocol (EAP). Get supported:

• Authentication via SIM card data
• Authentication via a digital X.509 certificate
• Authentication by password and username

Once the client and hotspot have agreed on an authentication method, the necessary data is forwarded to the network operator’s authentication server or the roaming partner. After the server confirms successful authentication, the hotspot activates the mobile device, and the Wi-Fi network can be used.

Benefits Of Hotspot 2.0 For Network Operators And End Customers

Hotspot 2.0 offers network operators and end customers numerous advantages. Logging in to a Wi-Fi hotspot is automated and does not require user interaction or input of user IDs. For the user, Wi-Fi networks are just as easy to use as cellular networks. The transmission of the data is encrypted and secure by WPA2 Enterprise Security. The network supply is also improved for the end customer since the optimal network technology can be used automatically at each location. Ideally, users benefit from higher bandwidths and shorter response times and save mobile data volume.

Network operators no longer have to laboriously provide their customers with the access data required to use the Wi-Fi network. The authentication takes place automatically, for example, based on the SIM card’s data installed in the terminal. Network traffic can be shifted from 3G, 4G, or 5G cellular networks to Wi-Fi networks to prevent traffic jams caused by too many end devices or excessive use (mobile traffic offloading). The cell phone networks are relieved. For the network operator, the investment in the cellular infrastructure and the radio frequency licenses is reduced.

Other advantages of Hotspot 2.0 are:

• Better customer loyalty through the conclusion of Hotspot 2.0 roaming agreements
• Cross-manufacturer standard – support through numerous hotspot solutions, mobile devices, and operating systems such as iOS, Android, Windows, and macOS
• Possibility of certification of end devices: “Wi-Fi Alliance Certified Passpoint.”
• Better network coverage in areas with high user density and buildings thanks to the automatic offloading of cellular traffic into Wi-Fi networks
• Reduction of the energy consumption of mobile devices by using local Wi-Fi hotspots instead of cellular networks.

A Society Increasingly Connected To The Network

As we say, today we have many computers connected to the Internet. We are talking not only about computers and mobiles, but many other devices such as televisions, tablets, electronic books that also have a connection.

All this means that we are facing a society that is increasingly connected to the network. We have a wide range of possibilities that facilitate our day today. This undoubtedly adds value to the technology, as we have more functions and features.

But to ensure that all these devices that we mentioned are managed correctly we need a central team, an administrator. That’s where the router piece comes in. It is used to manage connections, to be able to offer the Internet to other computers safely and efficiently.

However, not all are the same, as we have mentioned. Times change and so do the appliances we use and the needs we create. That’s where the Smart or intelligent routers emerge, which offer us different functions and characteristics.

What Is A Smart Router

A Smart router offers additional functions to the traditional ones. That is, we do not manage the connections simply from the router panel, it has greater optimization and characteristics for the day-to-day of the users and the current times.

For example, an intelligent router allows you to manage the users who are connected from your mobile, to be able to eject devices from the network, to control how long a computer browses, etc. It allows you to have greater control regarding security, a factor that is so important. We can manage the keys intelligently, choose which computers connect or not, etc.

But also improve the management of Internet coverage and speed. It may be that a certain computer requires more speed at a given time, more resources to function properly. A smart router allows you to better manage the way you offer the Internet to other connected computers.

We already know that having a good Internet speed, a stable connection that does not have failures is something essential for all types of users. However, sometimes we can have problems and much of the fault is with the configuration of the router. That is where this type of equipment comes into play, which can better manage the connections to reduce problems to a minimum.

This type of device arises mainly from the needs of users. And it is that we have more and more devices that require greater management, more adequate control, and tools that also allow us to improve connections. In this way, we can gain security, stability, and of course speed. In the end, the sum of everything is what makes a product have higher quality.

The Rise Of IoT Devices

But all this we mentioned has the main reason: the rise of IoT devices. We have more and more computers connected to the Internet in our homes. They are very varied devices, which can range from smart bulbs to refrigerators, through televisions or video players.

All these computers are connected to the Internet and will need a router. These smart routers are the ones that are going to offer a greater range of possibilities and are going to create new functions so that connections flow correctly.

Modern routers have changed a lot from the ones we used a few years ago. They have more features to manage all connections, more possibilities to improve speed or performance.

In short, we can say that Smart routers are already part of the present, but they will be even more important in the future. The rise of the Internet of Things devices leads to the need for more resources for our day today.

The WiFi connection has changed life at home, at work, and in practitioners around the world, has made us forget about the annoying cables to offer us the same or at some point better results but there are still people who still need this specific case. network type. For this, we have the alternative that allows the input to Ethernet in smartphones without too many complications.

Steps To Connect The Mobile To The Cable WiFi Router

Best of all, this method that we are going to know can be used on all mobiles, both Android and iPhone and we do not need applications or configure settings. We can also forget passwords, since being by cable we skip this step.

You just have to locate the USB Type C input or the Lightning input of your mobile and get the accessories that we are going to show you below.

Accessories We Need To Connect The Mobile To The Router

As you can see for yourself, Ethernet cables cannot be connected to a mobile, basically because the plug does not fit. We do not have to force it or look for a trick based on stripping the cables, the only thing we need is an adapter that goes from the Ethernet cable to a transformer that converts the signal and emits it through a USB Type C output.

This accessory can be used with our mobile or not even with computers that do not have this type of input, something increasingly common. It can be found on Internet portals or in electronic stores, if we show them the images that we share here, they will surely help you.

The same accessory will be the one that we need in the iPhone although in this case, the cable will have a different end with the Lightning cable, the one that Apple uses in the iPhone. They are not interchangeable, so according to our mobile, buy one or the other.

Also, we will have to resort to an Ethernet cable no matter how long it is or how old it is, anyone we have at home can be used to complete the connection.

How To Connect It

Although it is not a difficult process to imagine, we want to clarify that you do not have to carry out any configuration on mobile phones. I’m just afraid to use the accessory to connect it to our mobile and then make the Ethernet input in the ports that we find at the back of our WiFi router.

When we remove the accessory from our mobile, the WiFi connection will work as it did until now and we will not notice any changes. We can keep this accessory in our fixed workstation and when it is time to connect it to obtain the best result via network cable.

The Cable Is The Solution To Various Problems

If you still haven’t found the need for this accessory, we are going to show you some situations where it could be of great help and end up with problems that we have had for a long time.

• Improve Speed.

Although WiFi technology has improved markedly, it is not comparable to what can be achieved over the cable. We will take advantage of all the power contracted in our fixed network and we forget about the interference.

There will be no outages since the connection is direct by cable, we will have access to the highest possible bandwidth.

• Too Many Products Connected To WiFi

When we have a high volume of gadgets or devices at home, the network is likely to become saturated. To fix it we can free the WiFi using the cable even with the mobile phone through the steps that we have explained.

• WiFi Key Does Not Work

Although it is something that purchases should solve quickly, at a certain moment the network cable can save us from a hurry and make sure we stay connected even if the rest fails.

Wi-Fi Quick Check

A valuable first step is to do a brief analysis of your situation. To help you, there are useful analysis tools such as the Ekahau HeatMapper, recommended by experts. This program allows you to start creating a floor plan of your house to later measure the level of Wi-Fi coverage.

Position The Router Correctly

Is your WiFi too slow or does the connection stop completely too often? This is mainly due to a range problem since in many houses the router is located in a corner. Ideally, place it in a central, slightly elevated position, such as on a table or closet in the middle of the house. Also, the router should not be blocked by other objects in front of or next to you. If your router has external antennas, they can be oriented at different angles, and you can try various positions until reception improves.

Is The Router Too Old

If you have to replace your old router, the new model should support the new Wi-Fi 5 (Wi-Fi ac) standard, which is considerably faster than Wi-Fi 4 (Wi-Fi n). Furthermore, a part of Wi-Fi 4, the 2.4 GHz band, is extremely overloaded in many urban areas.

Your Wi-Fi will regain speed again by switching to the 5 GHz band of the Wi-Fi 5 standard. However, this only works if Wi-Fi receivers such as a smartphone, laptop, or tablet are also Compatible with the new Wi-Fi 5 standard.

Wi-Fi Repeaters For Short Distances

On large floors or single-family homes, there may be long distances, walls, or even reinforced concrete ceilings between the router and the Wi-F receivers. These obstacles act as a brake on the Wi-Fi signal, which becomes increasingly slow and, in the worst case, is completely lost. Using a Wi-Fi repeater is useful for shorter distances, such as from one room to another. However, it is not suitable for large homes because repeaters also use the Wi-Fi network for data transmission between them.

Internet From The Socket

Powerline adapters are a great solution for a good connection. The trick: they use the house’s electrical circuit as if it were a long data cable. The advantage: Walls, concrete ceilings, and even underfloor heating systems are no longer an obstacle because the solution is cable based.

Powerline WiFi adapters plugged into any electrical outlet create a fast internet access point with 100% speed. Also, installation is very simple: just plug in the adapter, wait a few moments, and start browsing. Today’s models combine the best of Wi-Fi technology with the fastest Powerline technology.
