Abstract How to deliver teaching materials in lectures is one part that determines students understand the material presented, especially when lecture material is something that requires equipment that supports outdoor activities or requires practicum devices that are not possible to apply to the room for example is practicum about depicting Fresnel Zone and Sometimes monotonous delivery bores students so that they are not interested enough to have difficulty in understanding lecture material.
One way that can be done to overcome this is by using visual equipment so that what is conveyed visually makes students interested in the material Submission visually in the room is also a problem when the number of students is For that we need equipment that can provide information visually and is easy to use or carry that can stimulate the activities of students to interact.
Augmented Reality is a visual model that can provide new experiences in interacting between real objects and virtual objects in the form of three dimensions, using augmented reality packaged as learning material can help students to understand teaching materials in lectures.
Keywords Ai Augmented Raeality.
Utilzation Of Instructional Media INTRODUCTION Media in delivering material in education is an integral part of the implementation of teaching and learning.
The way of delivering material in teaching and learning affects the desires and interests of students to understand the material presented.
Bethany .
suggests that the learning process is the process of delivering messages/material from the message giver .
to the message recipient .
Changing material in the form of symbols, both verbal and non-verbal, is called encoding, and the interpretation of these symbols is called The decoding process is very dependent on educators in changing the material presented so that it can be understood by students.
Sometimes even using visual media is not necessarily able to provide understanding to students about the material presented, especially subject matter that requires special equipment.
Networking courses require inexpensive equipment when the material presented requires outdoor activity.
Augmented Reality is an application that combines the real world with the virtual world in two-dimensional and threedimensional forms that are projected in a real environment at the same time.
Augmented Reality is often referred to as augmented reality.
Augmented Reality is often used in games and advertising media.
Augmented Reality or Augmented Reality can provide new experiences in terms of the interaction between users and the media to be delivered.
In the learning model that requires learning media that requires expensive equipment, added reality is a solution to overcome this.
Students can understand a concept that is conveyed through interactive activities that exist in augmented reality.
As in explaining how the picture of the Fresnel zone in computer network lecture material is certainly more interesting if it is presented visually using augmented reality.
The added reality can be implemented into equipment that uses visual media such as computers and communication equipment so that students can easily use them and can do a practicum in virtual.

RESEARCH METHOD
To be able to implement it into an Android device, it requires supporting hardware and Hardware requirements are as follows:
- Android smartphone with camera features and Android 8.
1 Oreo operating system - A computer with a core i7 processor with a minimum of 4Giga memory.
Software requirements are as follows:
- The Vuforia API as a support module for Unity for Reality is added in this case as a marker identifier.
- 2018 version of Unity as an Augmented Reality processor and as a destination for the program to run into the Android operating system or other platforms.
- Visual Studio with C # programming language as editor and compiler.
System Design System design using a use case illustrates the interaction between the user and the Augmented Reality system as shown in the use case diagram in Figure 1 below:
Marker <<include>> Realitas Tertambah User <<include>> Obyek 3D Figure 1.
Augmented Reality Use Case Diagram As seen in Figure 1, there is an Augmented Reality process by recognizing a marker as a place where 3D objects will be displayed further through the added Reality process, the merging between objects is presented to the user as a user.
Furthermore, augmented reality will recognize two marker objects and replace the marker object with a wifi tower virtual object in the form of a 3D object.
Then the process of drawing the Fresnel zone object that connects the two towers is carried out.
The following is a system design that will be carried out in the learning model using Augmented Reality.
To be implemented into an Android device, several steps can be described in the form of a flowchart, as shown in Figure 2 below.

Fresnel Zone augmented Reality processes 2 3D Model Creation The 3D Model is built using 3D processing software, namely using a blender which is saved in the fbx format, 3D models are imported into Unity to manipulate interactions between 3D objects that will appear on markers in Augmented Reality.
3 Marker Making Markers are made using vector image processing software which is then saved in JPG or PNG format.
The marker object used is as shown in Figure 3 and Figure 4 below.

- F1 = Freznel Zone .
- f = frequency of work (GH.
- d1 = the distance between Tx and the obstacle .
- d2 = the distance between the Rx and the obstacle .
- D = d1 d2 = distance between Tx and Rx .

CONCLUSION
By looking at the results obtained, it can be concluded that augmented reality provides another model for learning, especially in terms of visual presentation.
Learning in this model requires the activity of the subject to carry out activities or for the interaction of the subject with the system so that changes can occur directly.
In the added relation-based learning model, the subject will get new impressions and experiences in learning and more.
SUGGESTED
For further research, it can be carried out on dynamic marker objects without using static symbols.
And further research can be developed in the form of a cloud so that it is not static in one material.
