“SK Telecom, the operator partnering with Samsung to bring the Galaxy S10 5G, is offering 5G and LTE aggregation to provide ultra-fast download speeds”
The Samsung Galaxy S10 5G has been understandably seeing a lot of interest, since becoming among the first mainstream flagship 5G smartphone to be announced in global markets. However, while the hardware is already here, the networks seem to be taking longer in providing the effective bandwidth that would facilitate high speed internet access. Now, Korean telecom operator SK Telecom appears to have found an answer, with carrier aggregation.
According to a new report, SK Telecom has already tested its 5G network speeds on the Samsung Galaxy S10 5G, wherein it implemented carrier aggregation to aggregate or bring together bandwidth from its LTE and 5G spectra. This, as a result, combines bandwidth of 1.5Gbps from the 5G spectrum and 1.15Gbps from the LTE spectrum. With the Galaxy S10 5G being equipped with a gigabit-class modem compatible with carrier aggregation, SK Telecom managed to obtain download speeds of 2.6Gbps on the mobile device, which is quite a landmark.
For reference, a download speed of 2.6Gbps equates to downloading a 2GB movie in HD resolution in just six seconds and a VR video of 10GB file size would take merely 30 seconds. SK Telecom has also announced that after launch, the speed will be increased to 2.7Gbps later this year. Carrier aggregation is deemed as essential technology that not only improves the overall network speed, but also the overall quality and latency of the network. With aggregation, one major advantage is the utilisation of unused spectrum, which helps operators provide better network quality, particularly in congested areas.
With 5G still at its nascent stage, network quality should not be an issue since a large part of the spectrum shall remain vacant, and download speeds and overall data and voice quality should be great. It is only when the network starts seeing congestion in metropolitan areas will we start seeing the benefit of technologies such as carrier aggregation. South Korea has postponed its commercial 5G launch on grounds of the service being too expensive for the general public.
At almost $60 (approx Rs 4,200) per month for the average 5G subscription plan, it remains fairly expensive for now. However, once 5G networks gain traction, the prices are certain to go down significantly.
