Channel - A Wi-Fi channel is a specific range of frequencies used for communication between wireless devices. Wi-Fi networks typically divide these frequencies into 14 channels in the 2.4 GHz band, 34 channels in the 5 GHz band, and up to 59 channels in the 6 GHz band.

### FEC_K and FEC_N
* FEC_K and FEC_N
FEC_K and FEC_N are parameters used in Forward Error Correction (FEC) to define the structure and efficiency of error correction codes.
FEC_K and FEC_N are parameters used in Forward Error Correction (FEC) to define the structure and efficiency of error correction codes.
#### FEC_K
#### FEC_K
K refers to the number of information (or data) bits in a block before error correction encoding is applied.
This is the actual data that needs to be transmitted without any redundancy added for error correction.
K refers to the number of information (or data) bits in a block before error correction encoding is applied.
This is the actual data that needs to be transmitted without any redundancy added for error correction.
#### FEC_N
#### FEC_N
N refers to the total number of bits after error correction encoding has been applied.
N refers to the total number of bits after error correction encoding has been applied.
This includes both the original data bits (K) and the redundant bits that are added for error detection and correction.
Relationship Between FEC_K and FEC_N
This includes both the original data bits (K) and the redundant bits that are added for error detection and correction.
Relationship Between FEC_K and FEC_N
The difference between N and K represents the redundancy added by the error correction code. In other words, the redundant bits are used to detect and correct errors in the transmitted data.
The difference between N and K represents the redundancy added by the error correction code. In other words, the redundant bits are used to detect and correct errors in the transmitted data.
```mathematica
N = K + Number of Redundant Bits
```
```mathematica
N = K + Number of Redundant Bits
```
Example
Example
If FEC_K = 1000 and FEC_N = 1200, this means 200 redundant bits were added to the original 1000 data bits, creating a total of 1200 transmitted bits.
If FEC_K = 1000 and FEC_N = 1200, this means 200 redundant bits were added to the original 1000 data bits, creating a total of 1200 transmitted bits.
Code Rate
Code Rate
The ratio of information bits (K) to the total bits (N) is called the code rate:
The ratio of information bits (K) to the total bits (N) is called the code rate:
```mathematica
Code Rate = K / N
```
```mathematica
Code Rate = K / N
```
For example, if K = 1000 and N = 1200, the code rate would be:
For example, if K = 1000 and N = 1200, the code rate would be:
```yaml
```yaml
Code Rate = 1000 / 1200 = 0.833
```
This means that 83.3% of the transmitted bits are actual data, and 16.7% are used for error correction.
Code Rate = 1000 / 1200 = 0.833
```
This means that 83.3% of the transmitted bits are actual data, and 16.7% are used for error correction.
#### Usage in Communication Systems

FPV - FPV stands for First-Person View, a technology that allows users to experience a live video feed from a camera mounted on a drone or other remote-controlled device as if they were in the pilot's seat. FPV provides a real-time, immersive perspective, enhancing control and situational awareness during flight or remote operation.
