🔴Using frequency Band 700 MHz, BW= 20 MHz with: LTE, 5G and theoretical possibilities of 6G:

Example Scenario (Not Real-Life Deployment):

➡LTE:
Using 700 MHz frequency & BW= 20 MHz:
- Equation: Data Rate = Bits per symbol × Symbol rate × Bandwidth
- Bits per symbol: 6 (using 64-QAM)
- Symbol rate: 15,000 symbols/sec/MHz
- Bandwidth: 20 MHz

Calculation:
-Data Rate = 6 *15,000 *20 = 180 Mbps 
With MIMO:
- 2x2 MIMO: 180 *2 = 360 Mbps
- 4x4 MIMO: 180 *4 = 720 Mbps

-Coverage: Up to 10-15 km in rural areas.
-Users per Cell: 100-200 (rural), 400-600 (urban).

➡ 5G:
Using 700 MHz frequency & BW= 20 MHz:
- Equation: Data Rate = Bits per symbol × Symbol rate × Bandwidth
- Bits per symbol: 8 (using 256-QAM)
- Symbol rate: 15,000 symbols/sec/MHz
- Bandwidth: 20 MHz

Calculation:
-Data Rate= 8 *15,000 *20 = 240 Mbps 
With Massive MIMO:
- 8x8 MIMO: 240 *8 = 1,920 Mbps
- 64x64 MIMO: 240 *64 = 15,360 Mbps

-Coverage: Up to 10-15 km in rural areas.
-Users per Cell: 500-1,000 (rural), 1,000-3,000 (urban).

➡ Future 6G:
Using 700 MHz frequency & BW= 20 MHz:
- Equation: Data Rate = Bits per symbol × Symbol rate × Bandwidth
- Bits per symbol: 10 (using 1024-QAM)
- Symbol rate: 15,000 symbols/sec/MHz (expected to be higher with advanced tech)
- Bandwidth: 20 MHz

Calculation:
 -Data Rate = 10 *15,000 *20 = 300 Mbps 
With Advanced Massive MIMO:
- 256x256 MIMO: 300 *256 = 76.8 Gbps

-Coverage: Up to 10-15 km in rural areas.
-Users per Cell: Several thousand (rural), potentially 10,000+ (urban).

Main Differences;

1-Data Rates with MIMO Configurations
LTE (4G): Up to 180 Mbps with a single 20 MHz channel, up to 720 Mbps with 4x4 MIMO.
5G: Up to 240 Mbps with a single 20 MHz channel, up to 960 Mbps with 4x4 MIMO (common), up to 15,360 Mbps with 64x64 MIMO (theoretical).
Future 6G: Up to 300 Mbps with a single 20 MHz channel, up to 76.8 Gbps with 256x256 MIMO (theoretical)
2-Coverage: All Technologies: Coverage remains similar with up to 10-15 km in rural areas, but the practical range is usually less in urban areas due to higher frequency bands and obstacles.
3-User Capacity: increased with each new technology

Other Frequencies with a 20 MHz bandwidth:

- Lower Frequencies (e.g. 600 MHz): Better coverage, lower data rates.
- Mid Frequencies (e.g. 1.8 GHz): Balanced coverage and data rates.
- Higher Frequencies (e.g. 3.5 GHz): Higher data rates, smaller coverage.
- Millimeter Wave (e.g. 24 GHz): Extremely high data rates, limited range.

Note: While higher MIMO configurations (e.g. 64x64) are technically feasible, they are not typically deployed at lower frequencies like 700 MHz due to physical antenna size and practical deployment constraints. Higher MIMO configurations are more commonly used at mid-band frequencies (e.g., 3.5 GHz) and mmWave frequencies (e.g., 24 GHz), where the smaller wavelengths allow for more compact antenna arrays.
