In telecommunications, 6G is the 6th generation standard for telecommunication that is currently under research and development for wireless communication technologies for supporting cellular data networks. It is the successor of the 5G network and will be significantly faster. The development of 6G communication technologies requires new devices that will access into Terahertz spectral range.

Introduction

Compared to 5G, the most outstanding difference between 5G and 6G is that 6G communication technology will access into Terahertz(THz) spectral range. To access the terahertz frequency spectral, we need electronic devices that can operate in the terahertz frequency environment. Some high-speed electronic devices such as High Electron Mobility Transistor (HEMT) has already been used at the top edge of the communication devices, and the result is successful. However, other high-speed electronic devices such as Heterogeneous Bipolar Transistors (HBTs), Resonance Tunneling Diodes (RTDs) have even better high-frequency performance.

Background

6G Requirements

As 5G initiated, many organizations have already defined the 6G system in various ways. A difference that distinguishes 6G telecommunication technology from its predecessors is that 6G technology can access into Terahertz frequency range. The development of 6G technology does not only mean the revolution of telecommunication technology, it also means the speed of wireless data transmission technology will be progressed significantly. The following table shows the comparison of 4G, 5G and 6G network systems.

Key requirements of 5G, beyond 5G and 6G network systems
KPI 5G Beyond 5G 6G
Operating frequency bandwidth Sub-6 GHz Mm-Wave for fixed access Sub-6 GHz Mm-Wave for fixed access Sub-6 GHz Mm-Wave for mobile access

Exploration for higher frequency and THz bands
