Can Satellite Internet Replace 5G? Detailed Analysis

Detailed Comparison of Satellite Internet and 5G

1. Speed and Latency

Satellite Internet:

• Starlink download speed: 150-200Mbps (can reach up to 300Mbps in the future)
• Latency: 20-40ms (significantly lower than traditional satellite networks)

5G Network:

• Download speed: Can reach from 700Mbps to 1Gbps, 10 times faster than 4G
• Latency: Can be as low as 1-4ms, almost zero in ideal conditions

2. Coverage Area

Satellite Internet:

• Global coverage, not limited by terrain
• Ideal for remote areas, islands, ships, where telecommunications infrastructure is limited
• No need for complex ground infrastructure

5G Network:

• Coverage depends on BTS station infrastructure and fiber optics
• Mainly concentrated in urban areas, high population density
• Difficult to deploy in remote areas, complex terrain

3. Usage Costs

Satellite Internet:

• High initial equipment cost: Around 400-600 USD for the transceiver
• Monthly service fee: 99-110 USD
• Approximately 20 times more expensive than 4G/5G networks in Vietnam

5G Network:

• Device cost: Only requires a smartphone that supports 5G
• Service fee: Equivalent to or slightly higher than 4G, about 100,000-300,000 VND/month
• Suitable for the majority of general users

4. Stability and weather impact

Satellite Internet:

• Affected by bad weather: heavy rain, storms, snow can degrade signal quality
• Need to place the antenna in an open area, not obstructed

5G Network:

• Less affected by weather
• Signal can be weakened when passing through obstacles like thick walls, tall buildings

Can Satellite Internet Replace 5G?

Câu trả lời là: KHÔNG – hai công nghệ bổ sung cho nhau hơn là thay thế

Theo chuyên gia Affandy Johan, Internet vệ tinh như Starlink bổ sung chứ không thay thế mạng truyền thống, đóng vai trò như một “lớp phủ” quan trọng cho kết nối nội địa.

Why can't it replace?

1. Different usage characteristics:
   • 5G: Suitable for most urban users, reasonable cost, high speed, low latency
   • Satellite Internet: Ideal for remote areas where there is no telecommunications infrastructure
2. Capacity limitations:
   • A satellite system has a limit on the number of simultaneous users in an area
   • 5G can serve a large number of devices in a small area
3. The cost difference is too large:
   • Satellite internet is more expensive than mobile networks, far beyond the affordability of many people

Conclusion

Satellite internet and 5G complement each other: 5G serves urban areas with high speed, reasonable cost; Satellite internet bridges the digital divide, connecting remote areas, islands where 5G is difficult to deploy.
