# Questions this project aims to answer | ||
## Descriptive Questions | ||
|
||
1. **General Statistics:** | ||
|
||
- What is the total number of spots recorded in a given time period? | ||
- How many unique receivers and transmitters are there in the data? | ||
2. **Time-Based Analysis:** | ||
|
||
- What is the distribution of spots over different times of the day or days of the week? | ||
- How does the number of spots vary over different months? | ||
3. **Geographical Analysis:** | ||
|
||
- What are the most common receiver and transmitter locations (latitude and longitude)? | ||
- What is the average distance between transmitters and receivers? | ||
|
||
### Analytical Questions | ||
|
||
1. **Signal Propagation:** | ||
|
||
- How does the signal-to-noise ratio (SNR) vary with distance? | ||
- What is the relationship between power and distance? | ||
2. **Frequency and Band Analysis:** | ||
|
||
- How does the frequency distribution look like across different bands? | ||
- Which band has the highest average SNR? | ||
3. **Performance Analysis:** | ||
|
||
- Which version of the software (Version) shows the best performance in terms of SNR? | ||
|
||
### Comparative Questions | ||
|
||
1. **Temporal Comparison:** | ||
|
||
- How does the signal propagation vary between different times of the day (e.g., day vs. night)? | ||
- How does the performance vary across different months? | ||
2. **Geographical Comparison:** | ||
|
||
- How does the SNR differ between different geographical regions? | ||
- How does the distance vary between different receiver and transmitter locations? | ||
|
||
### Complex Analysis | ||
|
||
1. **Pattern Recognition:** | ||
|
||
- Can we identify any patterns in the data that suggest certain times or conditions are better for signal transmission? | ||
- Are there any anomalies or outliers in the data that require further investigation? | ||
2. **Predictive Analysis:** | ||
|
||
- Can we predict the SNR based on other variables such as distance, power, frequency, and band? | ||
- Can we build a model to predict the best times and conditions for signal transmission? | ||
|
||
### Example Queries | ||
|
||
1. **Basic Query:** | ||
|
||
- How many spots were recorded on the 3rd band on June 10, 2024? | ||
|
||
```sql | ||
SELECT COUNT(*) | ||
FROM wspr_data | ||
WHERE Band = 3 AND Date(Time) = '2024-06-10'; | ||
``` | ||
|
||
2. **Signal-to-Noise Ratio Analysis:** | ||
|
||
- What is the average SNR for each band? | ||
|
||
```sql | ||
SELECT Band, AVG(SNR) | ||
FROM wspr_data | ||
GROUP BY Band; | ||
``` | ||
|
||
3. **Distance and SNR Relationship:** | ||
|
||
- What is the correlation between Distance and SNR? | ||
|
||
```sql | ||
SELECT CORR(Distance, SNR) | ||
FROM wspr_data; | ||
``` | ||
|
||
4. **Geographical Distribution:** | ||
|
||
- What are the top 5 transmitter locations by the number of spots? | ||
|
||
```sql | ||
SELECT TX_Loc, COUNT(*) as SpotCount | ||
FROM wspr_data | ||
GROUP BY TX_Loc | ||
ORDER BY SpotCount DESC | ||
LIMIT 5; | ||
``` |
