Yes. Devices that support 4.5G can continue to use the existing network.
5G technology does not only provide higher internet speeds. It also takes the mobile experience to the next level with more stable connections during peak usage, higher network capacity, and lower latency. Considering our daily usage habits, the benefits of 5G can be evaluated under three main categories.
A significant portion of mobile data consumption comes from video content. This includes videos viewed on social media platforms as well as digital streaming services such as Netflix, Disney+, and similar platforms.
Depending on the resolution, video content typically requires internet speeds ranging from 3 Mbps to 20 Mbps. When these speeds are available, content can be streamed smoothly and in high quality.
Thanks to the high capacity offered by 5G, users can enjoy seamless video streaming even in crowded locations such as stadiums, concert venues, large events, and busy city centers. Compared to 4.5G, 5G can support a much larger number of users simultaneously with high-quality connectivity, significantly reducing the impact of network congestion on performance.
Visiting news websites, listening to music, using social media, or messaging through applications such as WhatsApp make up a large part of everyday mobile internet use.
These applications generally require speeds between 1 Mbps and 5 Mbps. However, the key factor affecting user experience is not just speed, but also connection stability.
With 5G's increased capacity, web pages load faster, messages are delivered instantly, and online services operate more smoothly even during busy hours. As a result, users experience fewer connection slowdowns and enjoy a more consistent online experience.
Downloading files, applications, games, or TV episodes may represent a smaller portion of daily usage, but it is one of the areas where speed improvements are most noticeable.
In this category, the key factor influencing user experience is waiting time. As internet speeds increase, download times are significantly reduced.
For example, the approximate download time for a 0.75 GB application or a TV episode is:
| Internet Speed | Download Time |
|---|---|
| 10 Mbps | 10 min |
| 20 Mbps | 5 min |
| 50 Mbps | 2 min |
| 100 Mbps | 1 min |
| 200 Mbps | 30 sec |
| 500 Mbps | 12 sec |
| 1000 Mbps | 6 sec |
One of the biggest changes enabled by 5G is the reduction of download times from minutes to seconds. At speeds of 200 Mbps and above, waiting times are greatly minimized, allowing games, applications, and content to be ready for use much more quickly.
Telsim Super 5G helps businesses accelerate their digital transformation journey through faster speeds, lower latency, and more reliable connectivity.
