After we focus on how briskly a provider’s knowledge velocity is, we’re normally speaking about downlink speeds, or the velocity at which knowledge is transferred from the web to your cellphone. The lesser mentioned uplink speeds measure how briskly knowledge is distributed to the web out of your gadget. When bragging to your buddies about how briskly your wi-fi supplier is, the previous is the velocity talked about.
T-Cell achieves a record-breaking uplink knowledge velocity of 550Mbps in a business (non-lab) setting

The file uplink velocity of 550Mbps in sub-6GHz spectrum was achieved utilizing Launch 17 UL Tx Switching. This expertise makes use of a number of transmit antennas to enhance the reliability and knowledge price from the add connection to the bottom station. Utilizing completely different antennas to transmit the identical info makes it simpler for the community to obtain the sign.
The provider says that whereas speeds differ by location, typical on-device downlink knowledge speeds on T-Cell‘s nationwide 5G community are 89–418 Mbps with occasional peaks over 1 Gbps. Typical uplink speeds are within the vary of 6–31 Mbps. You possibly can see why a 550Mbps uplink velocity is one thing for T-Cell to crow about.
T-Cell says that whereas downlink speeds have all the time been the main focus of the wi-fi trade, the long run that the provider sees consists of connections which are interactive, cloud-connected, and run in actual time. T-Cell says that this implies uplink connectivity is extra essential than ever earlier than for energy customers, creators, and players. The provider says that it’s main the way in which as these customers want a cellphone that may add as quick because it downloads.
“Everybody obsesses over obtain velocity, however at T-Cell we see what’s coming, and uplink is the subsequent massive factor. Whether or not you’re importing 4K video, gaming in actual time, or powering a VR headset, this file reveals that T-Cell is already constructing the community for that future and targeted on bringing the very best buyer expertise.”
-Ulf Ewaldsson, President of Know-how, T-Cell
The file uplink knowledge velocity was not created by T-Cell in a lab however was achieved at an actual business website in Seattle. The wi-fi supplier used a few of the tech out there in 5G Superior, akin to Provider Aggregation. This combines single frequency bands right into a wider digital channel that hosts the next capability of visitors. Take into consideration how a lot quicker you’ll be able to drive on a freeway when extra lanes have been added. One other 5G Superior trick, MIMO (A number of-Enter A number of-Output), provides antennas to base stations and the goal telephones.
How T-Cell set the file
The dwell community demonstration was carried out on 100MHz of Time Division Duplex (TDD) spectrum (n41) and 35MHz of Frequency Division Duplex (FDD) spectrum (n25). The previous makes use of a single band for each uplink and downlink communication. The latter makes use of separate frequency bands for uplink and downlink communications. A MediaTek check smartphone was employed, sporting an M90 5G modem.
