Here’s how:
- It uses higher frequency bands that can carry more data.
- It connects devices through smaller cells placed closer together.
- It relies on advanced antennas (called MIMO — Multiple Input Multiple Output) to send and receive multiple signals simultaneously.
Together, these improvements make 5G dramatically faster and more responsive.
3. The Three Layers of 5G
5G isn’t one single frequency — it’s built on three main layers or “bands”:
a. Low-Band 5G
- Similar to 4G in coverage, but a bit faster.
- Travels long distances, good for rural areas.
- Speeds: around 100–250 Mbps.
b. Mid-Band 5G
- The balance between speed and coverage.
- Perfect for cities and towns.
- Speeds: up to 1 Gbps (ten times 4G).
c. High-Band (mmWave) 5G
- Extremely fast, uses millimeter waves.
- Limited range, ideal for stadiums, airports, or business zones.
- Speeds: up to 10–20 Gbps.
By combining these layers, 5G can deliver both wide coverage and extreme speed depending on location.
