The next wave of mobile connectivity is already here. Even though 6G is a way off, telecommunications firms are deploying 5.5G, also referred to as 5G-Advanced or 5G-A, that delivers much higher speeds, reduced latency, greater reliability, and enhanced efficiency compared to existing 5G technology. This is not a complete overhaul but an incremental improvement over the existing 5G technology standards through 3GPP Release 18.
What Is 5.5G?
5.5G, which is also known as 5G-Advanced, is an evolution of the existing 5G generation, connecting the current 5G technology with the future 6G. Some of its characteristics include smart network control, use of AI, reduced latency, better spectrum utilization, and ability to accommodate more sophisticated applications like XR, industrial automation, connected cars, and IoT. While moving from 4G to 5G required building an entirely different network architecture, going to 5G-Advanced doesn’t require this step from the users’ perspective.
How Fast Is 5.5G?
5.5G significantly improves data speeds and network responsiveness compared with standard 5G.
| Feature | Standard 5G | 5.5G (5G-Advanced) |
|---|---|---|
| Peak download speed | Up to 10 Gbps (theoretical) | Up to 10 Gbps or higher with improved real-world performance |
| Latency | Around 10 ms | Can be reduced to below 5 ms in supported deployments |
| Network reliability | High | Higher with AI-based optimization |
| Capacity | Improved over 4G | Better performance in crowded areas |
Actual speeds will depend on carrier deployment, spectrum availability, device compatibility, and local network conditions.
What’s New in 5.5G?
Key improvements include:
- Faster download and upload speeds
- Lower latency for gaming and video calls
- Better performance in crowded locations
- AI-powered network optimization
- Improved battery efficiency for connected devices
- Enhanced support for augmented reality (AR), virtual reality (VR), and smart factories
- Better satellite and positioning capabilities in supported networks
Which Smartphones Will Support 5.5G?
Only smartphones equipped with compatible modem hardware and software updates can take advantage of 5.5G. Some flagship phones already marketed as 5.5G or 5G-Advanced ready include selected premium models from:
- Samsung Galaxy flagship series (recent Snapdragon-powered models)
- Xiaomi flagship smartphones
- HONOR Magic series
- OPPO Find series
- vivo X series
- OnePlus flagship devices
- Huawei flagship phones (in supported markets)
Support ultimately depends on three factors:
- A 5.5G-compatible smartphone
- Carrier deployment of a 5.5G network
- A compatible mobile plan and software update
Will Existing 5G Phones Work?
Existing 5G smartphones will continue to work normally on current 5G networks. However, most older devices may not support the full range of 5.5G features because they lack the required modem capabilities or software support.
Is 5.5G Available Now?
Several telecom operators have begun deploying 5G-Advanced commercially in selected markets, with wider expansion expected through 2026 and beyond. Availability varies by country and carrier.
Should You Upgrade?
If you already own a recent flagship smartphone, it may receive 5.5G support through software updates where compatible hardware is present. If you’re planning to buy a premium phone in 2026, choosing a 5.5G-ready model will help ensure compatibility with next-generation networks as operators continue their rollout.
