• Enhanced Mobile Broadband (eMBB): 5G enables faster internet in dense areas and remote regions, supporting applications like smart grids and telehealth.
• Ultra-Reliable Low-Latency Communications (URLLC): 5G’s reliability supports mission-critical applications like industrial automation and connected drones, which 4G couldn’t handle due to higher latency and lower reliability.

Starlink Speeds vs. 5G and 6G

Starlink, operated by SpaceX, provides satellite internet via a low Earth orbit (LEO) constellation, with over 7,000 satellites as of September 2024. Its performance compared to 5G and projected 6G capabilities is as follows:

• Starlink Speeds: Starlink offers download speeds of 25–220 Mbps, with typical speeds around 100–150 Mbps, and upload speeds of 5–20 Mbps. Latency ranges from 20–40 milliseconds, significantly higher than 5G’s 1–5 milliseconds.
• 5G Speeds: 5G delivers 100 Mbps–10 Gbps, with peak theoretical speeds far exceeding Starlink’s. Its low latency (1–5 ms) makes it better suited for real-time applications. However, 5G’s coverage is limited in rural areas, where Starlink excels.
• 6G Speeds: 6G’s projected speeds of 100 Gbps–1 Tbps dwarf both Starlink and 5G. Its microsecond latency will far outpace Starlink’s capabilities, making it ideal for advanced applications. However, 6G’s terrestrial infrastructure may still lag in remote areas, where Starlink’s global coverage is advantageous.
• Comparison Notes: Starlink’s LEO satellites provide global broadband, competing with 5G in underserved regions but not in speed or latency. Against 6G, Starlink’s current technology will be significantly outclassed, though future iterations (e.g., Starlink Gen 2 or partnerships like T-Mobile’s satellite cellular service) may narrow the gap for specific use cases like text messaging or basic connectivity. Other players like Amazon’s Project Kuiper aim for similar LEO-based internet but are less developed.
