5G Technology to be used in Satellite Communications

The Union Cabinet declared earlier this year that it planned to open its space operations to the private sector under the newly established Indian National Space Promotion and Authorisation Centre (IN-SPACe). Commercial aerospace technologies such as the 5G spectrum are becoming increasingly relevant for military purposes. A variety of uses are already lined up for the technology, such as streamlining supply chain systems and frequency converting applications in military aircraft for better missions. Electronic combat and radar systems are also among the functions benefiting from private technologies, specifically millimetre-wave and radar. 

Scott Leithem, the A/D IST Services Integration Engineer for Keysight Technologies, said that the market for millimetre-wave is set to expand by up to 35.2% compounded annually between 2017 and 2023. The demand for smaller-sized objects is rising, fuelled by growth drivers and other factors like frequency and bandwidth. New and creative applications are being used in the space industry by the day, with scientists worldwide looking for smarter and faster ways to make outputs better. One of the direct results, according to Leithem, is that low-orbit satellites have generated demand for greater spectrum breadth. He added that laser connections for satellite links are being studied, and higher frequencies are also being probed for broader use in space operations.

5G’s low latency will be more significant in the communication industry, as the market appeal for smaller, sleeker phones is ever on the rise. 5G will also come into play in satellite communications in the applications of more compact camera technology and unmanned aerial vehicles (UAVs). The convergence of space tech and 5G will be fascinating to watch, Joel Dunsmore, a Research Fellow for Keysight Technologies, says. Wideband, flexible frequency conversion, and high-order modulation are among the central components of the space-5G merger. Other building blocks include focusing on converter tests and how to adopt electronically steerable antennas, he added. 

Wireless networks are evolving within the Aerospace and Defense space to a system with broader bandwidth and therefore improved system throughput. Higher operating frequencies today have made more bandwidths available, implying that more radios, nodes, and connection points are linked together. This has generated demand for next-gen channel emulation, especially for A&D use cases. Satellite transmissions and space to ground communication are among the applications in the A&D space. These observations were included in the Keysight World India event named Aerospace and Defense Track. The event, held online, was themed Innovate Next.
