Shown above is a good visualization of transmitting Radio Frequency (RF). This animation does not represent the real time travel speed of RF which is 30 kHz to 3 GHz. It was slowed down for visualization.
All electromagnetic waves including RF their travelling speed in vacuum or outer space is the same as the speed of light, meaning 300,000 km/sec. We can use this knowledge to estimate the speed of a webpage that can be downloaded anywhere in the world.
Application of RF speed and Optical speed in fiber optics in relation to
internet webpage access time. Assuming you are in Philippines which is about 13,215 km from US datacenter that manages INVBAT.COM web server and you click the webpage www.invbat.com, what is the estimated return time of the signal to your internet device? Answer total return time is 0.0881 sec. Assuming another 0.0881 time delay, INVBAT.COM webpage should be loaded in 0.1762 seconds. This calculation is valid if your data travels using RF and Fiber Optic Networks. But if you are using satellite with approximately 35,786 km from anywhere on the earth. The return time is 0.2386 seconds. Again assuming another 0.2386 seconds time delay, INVBAT.COM webpage should be loaded in 0.4772 seconds. This webpage access time is still very fast less than 1 second. So if it is taking more than 1 second, you need to remember that data signal travels several hundreds of router switches around the world and also your internet devices are storing data in memory cache to speed up your next access time. Soon you will have a faster download speed as more cloud technology web servers are becoming widespread, fiber optics cables, RF transmitter/receiver, and satellite transmission path are becoming common worldwide.
How to compute the Power Ratio
Given Poweroutput in W and Powerinput in mW
Given power output of RF amplifier is 10 W and the power input is 1 mW.
Solve for the Power Gain in dB.

Pr in dB ANSWER |
= | 10 *Log 10 |
Po in Watts
Pi in milliWatts
|
Here mW ( milliWatts ) is converted to 0.001 W in the program. Hence no need to write 0.001 just enter 1 for 1 mW.
But in manual computation use 1 mW = 0.001 W the reason is the Power ratio has no unit. Meaning the Watts unit in numerator must be divided by Watts unit in denominator in order to cancel out the unit.
Given power gain of RF amplifier is 40 db and the input power is 1 mW.
Solve for the power output in watts.

IN-V-BAT-AI is a valuable classroom tool that enhances both teaching and learning experiences. Here are some ways it can be utilized:
☑️ Personalized Learning : By storing and retrieving knowledge in the cloud, students can access tailored resources and revisit
concepts they struggle with, ensuring a more individualized learning journey.
☑️ Memory Support : The tool helps students recall information even when stress or distractions hinder their memory, making it
easier to retain and apply knowledge during homework assignments or projects.
☑️ Bridging Learning Gaps : It addresses learning loss by providing consistent access to educational materials, ensuring that
students who miss lessons can catch up effectively.
☑️ Teacher Assistance : Educators can use the tool to provide targeted interventions to support learning.
☑️ Stress Reduction : By alleviating the pressure of memorization, students can focus on understanding and applying concepts,
fostering a deeper engagement with the material.
📚 While most EdTech platforms focus on delivering content or automating classrooms, IN-V-BAT-AI solves a deeper problem: forgetting.
✨Unlike adaptive learning systems that personalize what you learn, IN-V-BAT-AI personalizes what you remember. With over 504 pieces of instantly retrievable knowledge, it's your cloud-based memory assistant—built for exam prep, lifelong learning, and stress-free recall.
"🧠 Forget less. Learn more. Remember on demand."
That's the IN-V-BAT-AI promise.
Understanding the difference between collaboration and automation

Augmented Intelligence is like a co-pilot: it accelerates problem-solving through trusted automation and decision-making, helping you recall, analyze, and decide — but it never flies solo.
Artificial Intelligence is more like an autopilot: designed to take over the controls entirely, often without asking.
IN-V-BAT-AI is a textbook example of Augmented Intelligence. It empowers learners with one-click recall, traceable results, and emotionally resonant memory tools. Our “Never Forget” promise isn't about replacing human memory — it's about enhancing it.

Note: This is not real data — it is synthetic data generated using Co-Pilot to compare and contrast IN-V-BAT-AI with leading EdTech platforms.
