5G mmWave vs. Sub-6 GHz: Which is Better for Streaming?
When considering upgrading to 5G technology for better streaming experiences, the choice between mmWave and Sub-6 GHz can significantly impact your viewing quality. If you’re looking to buy phones in Nairobi, understanding these technologies is crucial as they dictate the kind of 5G performance you’ll enjoy.
Understanding 5G Spectrums
5G technology operates on different frequency bands, primarily categorized into mmWave and Sub-6 GHz. mmWave, or millimeter wave, utilizes higher frequency bands (24 GHz to 71 GHz), offering incredibly high data rates, which are ideal for streaming ultra-HD content without buffering. However, its range is limited, often requiring numerous small cells for coverage, mainly in dense urban environments.
In contrast, Sub-6 GHz includes a broader spectrum from 1 GHz to 6 GHz, offering a compromise between speed and coverage. While Sub-6 GHz doesn’t match the peak speeds of mmWave, it provides better penetration through obstacles and wider coverage, making it suitable for both urban and rural settings.
Streaming Performance
For streaming, mmWave can theoretically deliver speeds up to 5 Gbps, which means you could watch 4K or even 8K video streams with virtually no lag in areas where mmWave is available. However, this is only in specific hotspots like city centers or large venues. On the other hand, Sub-6 GHz might cap out at around 400 Mbps but offers more consistent streaming quality over a larger area, making it more practical for everyday use.
Device Compatibility and Availability
When choosing devices, consider what 5G bands they support. Many phones, including the Samsung Galaxy S21, which you can find new around KSh 50,000 – KSh 60,000, or refurbished for KSh 35,000 – KSh 45,000, support both mmWave and Sub-6 GHz. However, not all regions deploy both technologies equally. In Kenya, you’ll find that affordable phones online in Kenya like the Xiaomi Mi 11 Lite, available new for about KSh 25,000 – KSh 30,000 or refurbished for KSh 18,000 – KSh 22,000, might only support Sub-6 GHz, which is more widely deployed.
Real-World Considerations
The choice also depends on where you’ll use your phone most. If your streaming happens in areas with mmWave coverage, the speed benefits are clear. But for most users, Sub-6 GHz’s balance of speed, coverage, and reliability might be more beneficial. Moreover, streaming quality isn’t just about speed but also about latency; mmWave offers very low latency, enhancing interactive streaming experiences like gaming or live sports.
Conclusion
Ultimately, for streaming, mmWave provides the highest potential speed and low latency but with limited coverage. Sub-6 GHz offers a more practical solution with better coverage and still significant speed improvements over 4G. When deciding to buy phones in Nairobi, ensure the device supports the 5G band that aligns with your local infrastructure and streaming needs. The choice between mmWave and Sub-6 GHz isn’t just about technology but also about where and how you plan to use your streaming capabilities.
