AT&T has successfully aggregated low- and midband spectrum in 5G SA uplink, a major milestone in the development of the next generation of wireless technology. The test, conducted in AT&T’s labs, aggregated 10 MHz of its low-band n5, or 850 MHz, and a couple different scenarios – 40 MHz and 70 MHz – with mid-band, or n77/C-band at 3.7 GHz.
This is the first time that any carrier in the US has successfully aggregated two carriers in 5G SA uplink. It is a significant achievement that demonstrates AT&T’s leadership in 5G innovation.
Uplink aggregation is a key feature of 5G SA that can significantly improve upload speeds and performance. By aggregating multiple carriers, carriers can increase the amount of bandwidth available for uplink traffic. This is important for a variety of applications, such as video conferencing, file sharing, and cloud gaming.
AT&T is already deploying 5G SA in select markets across the US. The company plans to continue expanding its 5G SA network throughout the year.
Benefits of Uplink Aggregation
There are a number of benefits to uplink aggregation, including:
- Increased upload speeds: Uplink aggregation can significantly increase upload speeds. This is important for a variety of applications, such as video conferencing, file sharing, and cloud gaming.
- Improved performance: Uplink aggregation can also improve the performance of uplink traffic. This can lead to a better user experience for applications that rely on uplink traffic, such as video conferencing and file sharing.
- Increased capacity: Uplink aggregation can also increase the capacity of the network. This means that more users can be supported on the network at the same time.
Impact of Uplink Aggregation on 5G
Uplink aggregation is a key feature of 5G that can significantly improve the performance and capacity of the network. As 5G continues to roll out, uplink aggregation will play an increasingly important role in delivering the benefits of 5G to users.
Conclusion
AT&T’s successful aggregation of low- and midband spectrum in 5G SA uplink is a major milestone in the development of the next generation of wireless technology. Uplink aggregation is a key feature of 5G that can significantly improve upload speeds and performance. As 5G continues to roll out, uplink aggregation will play an increasingly important role in delivering the benefits of 5G to users.
