A new technology called “UL Tx switching” may provide a massive leap in 5G upload speeds.
The previous record was just 275 Mbps.
As you may know, 5G networking relies on a mix ofmmWave, low-band, and mid-bandspectrums.

The new UL Tx switching technology is an upgrade for existing Sub-6 5G networks.
It artificially creates more uplink bandwidth by flipping a user through different combinations of Sub-6 frequencies.
T-Mobile paired up with Qualcomm and Nokia to test the capabilities of UL Tx switching.
As it turns out, UL Tx switching can provide a 25% boost in Sub-6 5G upload speeds.
T-Mobile reached 345 Mbps upload speeds, shattering the275 Mbps recordit set in January 2024.
Simultaneous tests were conducted in Australia byQualcomm, Telstra, and Ericsson.
Note that UL Tx switching does not improve download speeds.
This is particularly true in homes that use a 5G modem instead of a traditional broadband modem.
Unfortunately, we don’t know when UL Tx switching will be deployed.
