Technical Overview
- Millimeter Waves: Higher frequency waves (24 GHz and above) that carry massive data but have shorter range.
- Small Cells: Mini base stations that boost signal strength in high-traffic areas.
- Massive MIMO: (Multiple Input, Multiple Output) — Multiple antennas on base stations to handle more connections simultaneously.
- Beamforming: Smart antenna technology that directs signals precisely where needed, reducing interference and boosting efficiency.
4G vs. 5G Comparison
| Feature | 4G | 5G |
|---|---|---|
| Download Speed | 100 Mbps | Up to 10 Gbps |
| Latency | 30–50 ms | 1 ms |
| Bandwidth | Limited | High |
| Device Support | Thousands per km² | Millions per km² |
| Use Cases | Mobile internet, streaming | IoT, AR/VR, autonomous cars |
Spectrum Bands
5G operates across three main frequency bands, each with distinct use cases and capabilities:
- Low-Band (< 1 GHz): Covers large areas, good for rural regions but offers lower speeds.
- Mid-Band (1–6 GHz): Balanced speed and coverage, ideal for urban and suburban areas.
- High-Band (> 24 GHz): Offers ultra-fast speeds for dense city zones but has limited range and indoor penetration.
Tip: Effective 5G coverage requires a mix of all three bands for optimal speed and reliability.
