Abstract
Virtual reality is allowing to revolutionize many activities and allowing to achieve a realism
very close to reality, one of the requirements to achieve these objectives is the use of
computer resources for this work, such as memory, processor, storage capacity among others.
The use of various devices where each one performs a specific task and then can be
integrated, requires a connectivity structure that allows them to perform this work without
problems at maximum speed and without loss of connectivity. This connectivity is achieved
thanks to the use of the WIFI 6 protocol in its 5GHZ band, in this work a methodology is
proposed that uses this connection in an educational application, where resources and
information are shared between a computer and virtual reality glasses from the Oculus quest
2 brand, the results obtained are encouraging, having an ideal realism which is demonstrated
by the child's concentration on the visualization of a high speed and maximum resolution
video. The research concludes that the WIFI 6 protocol, in its 5GHZ working band, is the
optimal one for virtual reality applications, managing to work with the security that
connectivity is not lost and achieving an ideal realization by the shared use of the resources
available in all the devices that make up the solution.

1. Introduction
With the development of technology, many technological barriers and applications are broken that
previous years were difficult to be applied, today can be solved, the issue of connectivity and access
to wireless devices for shipping and the possibility of sharing resources is one of The problems that
are trying to solve with the new communication protocols, in this development we find works related
to the connectivity of wireless networks where ways of measuring performance through latency and
reliability are used, with the advances in RAN technology (Radio Access Network), having flat user
latency in a transmission between the transmitter and the station dedicated to the user, measuring
transmission and reception parameters such as wireless propagation, MEC (Mobile Edge Computing),
queue delay, errors in the physical layer such as BLER (Block error rate), where we can check the
error correction code, modem, di versatility and retransmission [1]. We find jobs where these
networks are used to search for large volumes of information. Such as the review of the subject with
Preferred Reporting Items for Systematic Reviews and Meta-Analysis Guidelines together with a
protocol accepted by PROSPERO, for which a search was made in the databases of PubMed, Embase,
BioMedCentral, available until October 31, 2019, for which a backward snowball was applied to
retrieve manuscripts, and articles related to the subject, relevant results and risk of bias, no missing
data information was provided, for which it is concluded that if we have a connection wireless with

high speed we can perform searches with data integrity, not allowing the loss of connection [2] [4].
We also find jobs related to D2D communication from which a lot of data can be obtained, to be able
to transfer it between nearby mobile devices, with which data can be transmitted through unicast,
groupcast and broadcast transmission, through D2D you can transmit audio files and high-speed
videos with low energy facilitating transmission such as Google Chromecast, IPTV with the use of
clusters and broadcast data, this link works without any obstacle, where a device can be used as a
hotspot as long as it has good connectivity [3 ] [5]. In the development of applications dedicated to
the verification of connectivity through techniques to saturate and stress communications equipment,
with the intention of measuring connectivity and the response to different uses and applications, with
an emphasis on urban-type connections, trying to verify maximum coverage and signal quality using
devices that can increase the range of WIFI networks [6] [7]. One of the factors that is commonly
used in the analysis and performance of a wireless network and with emphasis on a WIFI network, is
the number of connections that it can support, in this analysis it is important to verify the performance
and the number of users connected in a way. simultaneously and concurrently, one of the places
where this behavior can be verified are the university campuses, where we have a considerable
number of users between students and professors and the computers that are connected to the same
network [8]. Among the different studies trying to compare the performance between the different
protocols related to wireless communication, we found a comparison between the 3G mobile network
and the WIFI wireless network, where the results show that each of them has its applicability mainly
related to the amount of users that can be connected and the type of applications, the configurations of
these can be of great help when you have to work in parallel with both protocols, distributing the load
depending on the uses and applications [9]. One of the factors that makes it possible to indicate a
good connectivity between the devices and the transmitter, is the propagation lobe analysis that
generates the configuration of the before, therefore if the device is located between the area covered
by the lobe it will have a better reception of the signal, as we move away from the lobe, reception
begins to decrease directly proportional to the distance between the device and the lobe [10].
2. Materials and Methods
In order to develop and test the methodology, a sequence of structured steps is proposed in such a
way as to present and verify the results that can be obtained in each of the blocks, then the block
diagram of the methodology, which we solve in detail below.
Figure 1: Block diagram of the proposed methodology.
2.1. Device Description
The first block is related to the description of the devices to be used to demonstrate the
methodology, it is important to analyze, depending on the hardware used, we can exploit their
maximum capacity, in our particular case. The intention of the methodology is to be able to optimize
the computer resources necessary to be able to execute applications related to Virtual Reality, to
demonstrate the methodology a router with the WIFI 6 protocol will be used, some virtual reality
glasses of the Oculus quest 2 model and a computer, the details of each of them are described below:

2.2. Device Configuration
One of the main characteristics that these three main components share is the connectivity to the
WIFI 6 protocol, with which we take advantage of the 5GHz working band provided by the router,
with the Oculus quest 2 virtual reality glasses, we connect to the network 5GHz, also with the
computer we connect to the 5GHz network, in this way the 3 devices are connected to the same
network and through a single band, to take advantage of its maximum data transfer capacity. Next we
present in figure 2 the configuration of each of the devices.
Figure 2: Device connection diagram using the 5GHz band.

Having configured the three devices through the same wireless network, it remains to decide how
to share the same information between the computer and the Oculus quest 2 lenses, in order to
synchronize the contents, making it possible to view the same information on the lenses. computer,
the software that provides us with this task is the Virtual Desktop, which allows us to synchronize
content between the virtual reality glasses and the computer, one of the main characteristics is that it
needs large computational resources, between memory, hard disk and processing capacity, so with the
Oculus quest 2 lenses, we can provide these resources thanks to its internal configuration that was
described above, as well as the characteristics of the computer, described whose characteristics meet
the requirements of the application.
Figure 3: Synchronization application between the lenses and the computer.
In figure 4, you can see the final configuration ready to be able to operate any type of application
related to virtual reality, it is important to indicate that the diagram shows how the hardware described
and the necessary software interchange.
Having the virtual reality architecture configured, the next step is to test the methodology,
applying some need, trying to get the most out of this configuration in such a way that it can be
demonstrated to perform virtual reality applications, trying as much as possible for maximum
synchronization., connection, nitides and effects of virtual reality.
2.3. Application Example
As a third process of the methodology, an application example is presented where it is required to
test the configuration and synchrony between the virtual reality glasses and the computer. The chosen
example is related to the educational area which is the topic known as the reading plan, where
children read stories and interpret what they have understood, for the practical case the story is
presented in video form, but in this case, to the child it is presented to you through the virtual reality
glasses. The Oculus quest 2 lenses have built-in speakers which gives the possibility of emitting
sound without the need for headphones.
The results of the application of the methodology are presented below, where a video of a story is
presented, in Full HD resolution, where the visualization has its particular characteristics that we
present to describe below:
195
Figure 4: Synchronization diagram between hardware and necessary software.
Figure 5: View of the tale through Oculus quest 2 glasses
The Oculus quest 2 virtual reality glasses present a configuration in the presentation of objects, in this
case the effect represented by the story with the child is the feeling that the child has as if he were
participating in the story, which causes the The child understands and interacts with the story, thus
better understanding and interpreting what is being presented in the video, achieving a better
understanding and consequently improving learning through the effect of virtual interaction.
Figure 6: View of the View the story on the computer.
196
In figure 6, the story is presented on the computer screen, with a different perspective compared to
virtual reality glasses, in the development of the methodology, a control of what is being presented in
the lenses is required, therefore The control is in the computer and is achieved thanks to the Virtual
Desktop software, which sends through the WIFI network, the content to be viewed, in our it is
required to control from the computer what is displayed in the lenses, in this way In a real situation,
the teacher can control what her students see in the glasses.
3. Results
The results that are presented are related to the application of the methodology, we can indicate
that in the demonstration with the example about the presentation of a story at high speed and
maximum resolution, we can indicate that no type of interference was perceived, slowness,
disconnection or other factor that may interfere with communication and control from the computer
with virtual reality glasses.
We can indicate that with the use of the WIFI 6 network through its 5GHz band, it allows greater
connectivity and we can execute applications where it is required to send a greater amount of data,
measured by the transmission speed, as well as ensure the continuity of the connection. The
application allowed the sending of a video at high speed and maximum quality through the 5GHz
band, managing to demonstrate that the 5GHz band is suitable for Virtual Reality applications, where
the calculation is required to be carried out on the computer and the results presented through virtual
reality lenses, where this transmission is as fast as possible without loss, giving the sensation that it is
running in the lenses.
Next we present the images that correspond to the results of the application, from the perspective
of the sensation of virtual reality. The sensation that the child has is very important to evaluate
because he is focused on the story that is being presented, the continuity of the WIFI 6 signal, allows
the child not to perceive any interruption in the projection of the video, which causes a conformity of
the use of the wireless network in virtual reality applications. What is required in virtual reality
applications is to present the maximum possible reality, and it is achieved through a fast connection
and without interruptions.
Figure 7: Top and side view of child with virtual reality glasses.
In figure 7, observe the child with the Oculus quest 2 lenses, where it can be seen that the child is
totally focused on what is being projected, and this is achieved thanks to the use of the 5GHz band.
4. Conclusions
The conclusions that we must consider are related to the use of the WIFI 6 protocol in its 5GHz
band, which allows high connectivity without delay or losses, achieving a secure and available
197
connection so that it can be used as a tool for certain applications where more data traffic is required.
Virtual reality applications have a particularity, which is to be able to provide the greatest amount of
realization, so it requires a large calculation capacity as well as available resources, the use of a
computer where the calculation is carried out and the visualization through the Oculus quest 2 lenses,
allowed to evaluate the joint work of these two devices, having as a means of connectivity the WIFI 6
network in the 5Ghz band. We can indicate and recommend that for virtual reality applications, using
the use of development applications such as UNITY, UNREAL ENGINE, among others, where it is
required to perform large-scale calculations and be able to send to the devices that allow us to present
virtual reality, we recommend use the WIFI 6 protocol in its 5GHZ band, to ensure the maximum
possible realism.
