Abstract
Currently with the development of technology, we can find a number of devices with
different communication and connectivity technologies, which can be used for different
applications. We can find devices that can be connected through wireless networks using
protocols such as WIFI, Bluetooth, RF, among others, that allow information to be sent and
received. We also find devices that are used to store relevant and important information and
that is always available such as RFID. In an analysis to evaluate the strategy in solving
problems, we can find different ways to use these devices working individually, the
complexity of the solution grows increasing the level of complexity, if you decide to
integrate different communication protocols with the intention to have a more robust solution
that allows the integration of different technologies. In this paper we present a methodology
to be able to propose solutions based on the use of different communication technologies, in
order to find a sequence of steps necessary for choosing the right hardware as well as its final
integration. The results are presented through a sequence of steps for the implementation of
the methodology with the use of IOT and RFID technologies, as well as the description of the
frame for sending packets between the different devices, the methodology is easy to
implement as well as be scalable.

1. Introduction
Making a review of the literature, we found works related to determining the advantages in the use
of RFID technology in helping robots to navigate for use in hospitals, with the intention of automating
certain processes in the location and identification of patients to provide the services [1]. RFID
technology is commonly used in many industrial processes, as a mechanism for identifying equipment
and products among others, in order to automate processes, it is important to indicate that these
automated systems require truthful and accurate information, RFID technology provides us with these
characteristics, used in the pharmaceutical industry for the storage and storage of drugs [2]. Due to the
effects of the pandemic caused by COVID-19, there are problems related to the decrease in physical
contact between health personnel and patients, as a communication mechanism the IOT technology is
presented in order to identify people as well how to analyze the data that is generated [3]. The name
that is currently being used is the IoMT, which is constituted in the use of IOT technology applied to
health issues [4]. Many applications dedicated to exploiting the data generated by COVID-19, are
stored for later exploitation, these variables such as temperature, oxygen saturation, heart rate, blood
pressure, among others, can be captured and stored thanks to the IOT technology [5] [6]. The
pandemic is causing many of the processes related to the medical sector to be in the process of
digitization, in order to have less and less face-to-face relationship between the various sections of a

hospital center with patients, for this reason many related solutions arise to patients, diseases,
medications among others [7]. In the process of knowing in what state the patients are in relation to
the state of contagion by COVID-19, solutions are presented based on identifying the patients
according to their level of contagion and the process that is, through the use of RFID technology
analyzing data through the use of artificial intelligence techniques [8]. Know how technology is being
coupled more frequently in most actions and processes, thanks to IOT technology this integration can
be achieved, we find applications where it integrates IOT, Virtual Reality, Blockchain among others
with the aim of enhancing the use of data that are available and can be exploited [9]. The use of
technology is causing influence among the different professionals, we also find works related to being
able to identify how these technologies are causing an impact in different areas, asking about the level
of knowledge of the technology, the ability to interact and future applications [10]. In the present
work we find a methodology how we can integrate IOT technologies with RFID so that it can be
replicated in the solution of problems where the identification and availability of information is
required.
2. Materials and Methods
The proposed methodology allows establishing a direct relationship between the problem that can
be found and the solution that is being applied, based on the use of a technology that is available. In
figure 1, the procedures to be carried out are presented based on the analysis of the technical details
that we can indicate about some of the IOT RFID devices that we can have available, then a method is
presented to analyze how these two technologies can be integrated, as well as the presentation of how
to transfer the data of each one and finally in the third procedure it is proposed how to integrate both
technologies in a final application, then each of the aforementioned procedures is developed:
Figure 1: Block diagram of the proposed methodology.
2.1. Study of available technologies and their protocol of use
In the analysis to be able to solve problems in the area of technology, the first thing that we must
consider, depending on the problem, are the future electronic components to be used, in this sense the
choice of the appropriate device differentiates the success of the solution, the methodology that is
proposed is characterized by evaluating each of the components and analyzing their technical
characteristics, in figure 2 the flow diagram for choosing the appropriate device to solve the problem
is presented.

Figure 2: Flow chart for choosing the right device.
Below we describe the pseudo-code of the flow diagram, for the choice of the appropriate device:
Analysis of the problem, indicating the physical phenomenon to be used.
Having identified the way in which we will record the physical phenomenon, we proceed to
describe what electronic components we can use, with emphasis on the communication
protocol that it has in order to be able to export the data.
We ask if the selected device acquires the signal and can be exported, using a protocol that we
can handle.
If the answer is positive, we proceed to the selection of the device and analyze how to
integrate the final application.
If the answer is negative, we proceed to discard the device and analyze the next device on the
list.
2.2. Analysis for the integration of technologies
Having the selected devices, we carry out the analysis of each one of them in order to know their
technical details and how to make an integration between all the selected components, a consideration
that we can indicate, that up to this point, only the devices were selected, in this step we will analyze
if it can be compatible between them, the final selection of the devices depends on the analysis of the
technical characteristics of each device. Next, we present the detail of the devices that we can use,
explaining the technical details of each one.

In figure 3, we present the module dedicated to IOT communication where we can register
different types of signals and we can upload them to a web server for later exploitation, its technical
details are:

Direct communication with Google
Encryption Capability
Sensor reading per analog channel
Applicable MQTT protocol
A second electronic device is the one presented in figure 4, which is used for identification by
geolocation, so that it can be used to its maximum capacity it must be connected to a wireless
network.

A third device that we can find, is related to being able to control the power supply, by interrupting
the power supply, these devices are known as an intelligent switch, in figure 5, it can be seen.

A fourth device is related to RFID technology, where information can be stored and retrieved, it
requires a reading and recording device, it has the particularity of having a unique identification
number, which makes it ideal for applications where it is required. have order, location and
identification.

2.3. Methodology solution proposal
After having evaluated each of the components, we present a connectivity architecture, where all
the aforementioned devices can be used, in order to be able to share resources and characteristics in
order to be used in different applications.
In figure 7, we can see the connections of the 4 devices, each one has an application that
differentiates them from each one, with the IOT location device we can identify multiple objects in
real time, these can be static or dynamic, with the device Known as smart swich we can control
different equipment, with the RFID unit we can store information and that it is available, all data can
be stored on a web server and with this we can access the information at any time and from anywhere,
this functionality is achieved thanks to Microchip's IoT module. The 4 devices described above can be
integrated into a single application thanks to the fact that the 4 have a common characteristic that is
the WIFI connection, with which the 4 devices are connected to the same network and with this we
manage to share their resources for a specific application.

3. Results
The results that we present are related to being able to identify the technical characteristics of the
different devices that we find in the market, mainly those that can connect with wireless networks for
the transfer of information, to share resources and to be stored, with which we can solve two specific
problems:
First we solve a technology compatibility problem, managing to connect different devices
through a common feature that is connectivity via WIFI.
We present a methodology where it can be replicated and scalable to be able to solve different
problems related to connectivity and interoperability between devices.
The results help to strengthen the technical knowledge on connectivity and to be able to use
modern techniques such as IOT and RFID and the way how these can coexist in an application where
it can be integrated by multiple additional sensors, which can be installed in the IOT module, so that
the information of the different sensors that can be added to the solution and can be stored in a web
server, we can design a data package that can be integrated into the IOT module so that it can be sent
through the MQTT protocol, this data package is conditioned by the serial communication protocol
that supports the IOT module.
4. Conclusions
The conclusions that we can indicate at the end of the tests and functionalities, is that as
technology advances, new communication protocols emerge with increasingly better performance, it
is important to indicate that in the face of this problem, it is difficult to be able to change all the
devices that are counted as installed capacity, when you have a new technology, in this sense in many
applications we must see the possibilities that many devices of different technologies can coexist in a
single application, therefore the methodology also allows the ability to balance the workload, where
each component develops its own work for which it was designed.
Finally, we can conclude that in the analysis of the program, looking for a solution, not always the
sensor with the highest cost, the brand, can solve it, we can find economic devices that can be used in
complex solutions, everything will depend on the technical characteristics of the devices, for our
particular case, where we describe the characteristics of the IOT components such as RFID, we can
indicate that they are economical and can be applied to solve real world problems.
The conclusions reached at the end of the research, where we can indicate that in terms of
industrial automation, connectivity is very important and modular in the integration of systems and
with it the possibility of scaling, reviewing the activities carried out.
In the process of verification of the methodology, we can define and conclude that an important
factor, which is connectivity to a wireless network, this can be in the same network or in another
network, this requirement is very important, when identifying the proper devices connectivity is very
important.
