In September of this year, I started using AR augmented reality technology in natural science courses. In the anatomy physiology course, students can see the 3D virtual simulation of the human skeleton, no need to leave the classroom to run to the human skeleton room, and do not need to take a real human skeleton model, very convenient.
4D Anatomy This AR application allows high school students to study the human skeleton carefully in their leisure time. From different angles, they can zoom in and out and rotate freely. Users can also choose to watch the muscle system, nervous system or circulatory system, but for us, a single skeleton system is enough.
Students learn different types of bones and analyze bone structures as they examine more than 200 human bones. They can communicate and collaborate during the learning process. On 8 x 11-inch paper, AR technology presents a lifelike bone 3D effect, allowing students to sit anywhere in the classroom and even learn outdoors.
This AR human skeleton is not moving by itself unless you advertise bone paper. Students can use the iPad as a display device to view the skeletal system from different angles so that they can focus on specific bones.
I asked students to record their learning experience using the iPad's video capture feature. In this AR learning process, students are more than just a learner. They are also a storyteller, an expert, a teacher. Video can help them practice the pronunciation of some bones, and they can communicate verbally to express their learning insights.
Students use video editing software to edit the video, add titles, and add transition scenes and dubbing.
For the past three years, I have been teaching through video production, storytelling and other innovative ways. This is my first time applying AR augmented reality technology to teach. Here are some of my experience.
1. Give students plenty of time to explore. Not surprisingly, the first group of students left behind several tasks when using the 4D skeleton to complete the assignment because they did it too quickly. Based on my teaching experience, students need at least 2 days to complete this level of homework.
2. Encourage students to explore all aspects of using 4D bone applications. Many students do not zoom in and out of the skeleton during the learning process, and do not rotate the angle. In fact, this is one of the advantages of using AR applications.
3. Remind students to pay attention to the main things. Many students want to add their own ideas and features in the learning process, I am very encouraged. However, some students are biased and they add humor to the process. For example, a group of students spent a lot of effort to make a funny video without paying attention to the body skeleton.
4. Ask the students to check repeatedly. For example, during the video editing process, they can adjust the volume or add background music. There are several groups of videos that are too small to be heard, and the voice is not heard or added. When the students told me to finish the homework, I asked them to watch the video again to see if there were any changes or modifications. After repeated checks, students can upload videos and share them on social networks.
I will make some changes in the next tutorial. I will ask them to use AR programs to make AR books instead of making videos. I will ask students to take pictures of different bones and add them to the AR book. Students can add sound and their own graffiti. Once they are done, they can convert it into a video or convert it to a PDF file.
The human skeletal system used for teaching is very expensive, and replacing it with the AR program can greatly reduce the cost. Although video production software requires a fee, the 4D anatomy application is free and does not require WiFi connection.
Sector Panel Antennas, also known as sectorized antennas or directional panel antennas, are a crucial component in modern wireless communication systems. These antennas are designed to provide highly directional radiation patterns, enabling efficient coverage of specific sectors within a broader communication area. Their versatility and performance make them ideal for a wide range of applications, including cellular networks, public safety communications, and wireless broadband systems.
Classification Based on Coverage
-
Single-Sector Panel Antennas:
- These antennas are configured to cover a single, narrow sector of the overall communication area. They are typically used in smaller networks or as supplemental coverage in larger systems.
-
Multi-Sector Panel Antennas:
- Multi-sector panel antennas consist of multiple panels or elements arranged in a way that divides the overall coverage area into multiple distinct sectors. Each sector can be individually optimized and controlled, providing greater flexibility and coverage control. These antennas are commonly found in cellular base stations, where they are used to cover a larger geographical area efficiently.
Classification Based on Frequency Bands
-
Low-Band Sector Panel Antennas:
- Designed to operate in lower frequency bands (e.g., 600 MHz to 2.6 GHz), these antennas excel at providing deep indoor penetration and wide-area coverage. They are particularly useful in rural and suburban areas where signal propagation can be challenging.
-
Mid-Band Sector Panel Antennas:
- Operating in mid-range frequency bands (e.g., 2.5 GHz to 3.7 GHz), these antennas offer a balance between coverage and capacity. They are commonly used in urban and suburban areas, supporting a mix of voice and data traffic.
-
High-Band Sector Panel Antennas:
- Operating in higher frequency bands (e.g., 3.5 GHz to 5G+ frequencies), these antennas enable high-speed data transmission with reduced latency. They are increasingly being deployed in dense urban environments and for specialized applications such as mmWave 5G networks.
