LG moves 6G speeds closer to reality by launching terahertz data tests
Although widespread 5G is still a pipedream for many smartphone owners, LG claims it has made a significant step towards developing 6G. It transmits terahertz range (THz) data outside in Berlin over a distance 100m or 328ft.
- LG successfully tested data transmission of 6G THz at 100m distance.
- To deal with signal dropoff, a special power amplifier was employed.
- 6G won’t likely hit the markets until at least 2028.
The main problem with 6G THz has been rapid dropoff. LG claims that the test was solved by a power amplifier, which was developed in collaboration with Fraunhofer HHI (Fraunhofer Institute for Applied Solid State Physics). The amplifier produces a stable signal of up to 15dBm (decibel milliwatts) at frequencies between 155GHz and 175GHz.
LG states that 6G will be a standard worldwide in 2025. However, it is not expected to reach the commercial market until 2029. Samsung aims to deliver 6G by 2028 with a maximum speed of 1Gbps that is equal to landline fiber services.
6G THz broadcasts have the same problems as 5G’s variant mmWave. mmWave offers the fastest cellular speeds currently, but it has a limited range. Carriers often need to cover an area with transmitters in order to make it reliable. The technology is also not available outside major urban centers. It can also be easily blocked by buildings and may be affected by weather. Therefore, connections often go back to regular 5G/4G.
Many improvements to 5G or 6G are tied to visions of the future, such as high-fidelity Augmented Reality, commonplace remote surgical, and self-driving cars which can talk to one another. All these technologies require low latency. This is difficult on any cellular network.
