What are RU's ( Resource Units ) in #wifi

A single Wi-Fi channel is split into smaller frequency blocks called Resource Units (RUs). These RUs allow multiple devices to communicate at the same time instead of waiting, making Wi-Fi faster and more efficiently.

☑️ Channel Division: In Wi-Fi 6, 20/40/80/160 MHz channel can be split into small RUs (e.g., 26, 52, 106, 242 subcarriers).

☑️ OFDMA Usage: Each RU is assigned to a specific device, allowing multiple devices to communicate simultaneously.

🛑 Simple Explanation (Pizza Example 🍕)

Imagine a large pizza (Wi-Fi channel) Instead of giving the whole pizza to one person at a time, we cut it into slices (RUs) so that multiple people (devices) can eat (transmit data) at the same time.

🛑 Real-World Example: Office Wi-Fi

📲 Employee A (Video Call, High Data Need) → Gets a large RU (242-tone RU)

📩 Employee B (Sending Emails, Low Data Need) → Gets a small RU (26-tone RU)

📥 Employee C (Downloading a File, Moderate Data Need) → Gets a medium RU (106-tone RU)

✓ Result: All devices get their required bandwidth without delays, making Wi-Fi faster, smoother, and more efficient!
