The spectrum at 300 GHz is very attractive for wireless links operating at data rates of 40-100 Gbit/s. There are three important aspects:
- Frequency license situation and standardization: The frequency bands below 275 GHz are rather fragmented. The frequency band above 275 GHz is unregulated and standardization efforts consider continuous frequency bands of more than 40 GHz bandwidth
- Atmospheric attenuation window: There is a wide minimum of atmospheric attenuation between 185 and 315 GHz.
- Technology readiness: Latest short-gate III-V transistor technologies have reached maturity and can address system solutions at 300 GHz, offering low receiver noise figures and high transmit power levels, higher integration levels at a small chip size
Terapan validates the available technologies and approaches for the implementation of future beam-steering wireless data links at 300 GHz. It is a pilot study for future prototypes and R&D efforts towards commercial products.
In nomadic application scenarios, the devices are mobile but move rather slow and stay in their position for a period of time. Links can be blocked by moving obstacles, e.g. humans walking in the room. In this case an alternative communication link needs to be found by electronic beam-steering. Among the different indoor applications smart office and data centers are considered by Terapan.
