5.8-km 10-Gbps data transmission over a 120-GHz-band wireless link

TLDR

The system employs a millimeter‑wave amplifier built with 0.08‑µm‑gate‑length InGaAs/InP composite‑channel HEMTs to boost output power, and the authors performed 4.8‑km and 5.8‑km transmission tests that achieved error‑free 10‑Gbit/s data with forward error correction. The 120‑GHz wireless equipment delivers 10‑Gbit/s data over distances exceeding 5 km, with an output power of 16 dBm and supports data rates from 1 Mbit/s to 11.1 Gbit/s, achieving error‑free 10‑Gbit/s transmission with FEC at 5.8 km.

Abstract

We have developed 120-GHz-band wireless equipment that can transmit 10-Gbit/s data signal over a distance of more than 5 km. In order to increase the output power of the120-GHz-band wireless equipment, we used a millimeter-wave amplifier that integrates 0.08-μm-gate-length InGaAs/InP composite-channel high-electron-mobility transistors. The output power of the wireless equipment becomes 16 dBm. The wireless equipment can handle data rates of 1 Mbit/s to 11.1 Gbit/s and transmit 10-Gbit/s-class data signals with and without forward error correction (FEC). We conducted wireless data transmission experiments over a distance of 4.8 km and 5.8 km and succeeded in the error-free data transmission of 10-Gbit/s data with FEC.
