Keysight helps prove viability of 5G comms
31 January 2017, Telecoms, Datacoms, Wireless, IoT, Test & Measurement
Keysight Technologies recently collaborated with the University of California San Diego to demonstrate the world’s longest bidirectional phased-array link in the 60 GHz band.
At a link distance of 300 m, the 32-element array achieved a data rate of greater than 2 Gbps over all scan angles up to ±45 degrees. Data rates were 4 Gbps at 100 m and 500 Mbps at 800 m over most scan angles. Initial tests by a leading wireless provider suggest the system can deliver content to eight homes at a time at up to 300 m.
The entire phased array consumed 3 to 4 W of DC power in either its transmit (Tx) or receive (Rx) modes. This is due to the high-performance system-on-chip (SoC) designs UC San Diego created using the third-generation silicon germanium BiCMOS standard buried collector (SiGe BiCMOS SBC18H3) process from specialty foundry TowerJazz.
Keysight hardware and software enabled rapid prototyping of the system, as well as link equalisation and state-of-the-art performance measurements at 2 GHz modulation bandwidth. Central hardware elements were the M8195A arbitrary waveform generator, E8267D PSG vector signal generator and DSOS804A high-definition oscilloscope.
UC San Diego used Keysight’s Signal Studio software to define and generate the 60 GHz 802.11ad waveform, which was the basis for development. Keysight’s 81199A Wideband Waveform Center software helped the team link Tx and Rx, apply digital pre-distortion and improve error vector magnitude (EVM) perform-ance. The team also used Keysight’s 89600 VSA software to perform demodulation and analysis of advanced signals.
Key contributors to the UC San Diego effort were Bhaskar Rupakula and Ahmed Nafe, graduate students in electrical engineering; and Samet Zihir and Tsu-Wei Lin, electrical engineering post-doctoral fellows. All praised the quality of Keysight’s hardware, software and technical support.
All Keysight products used in the development of the 5G communication link are available now. For more information contact Lizzy Mabaso, Concilium Technologies, +27 (0)12 678 9200, info@concilium.co.za, www.concillium.co.za |
