A 5G satellite operator, OQ Technology has confirmed six pending patent filings in Europe and the United States. The patents aim to improve satellite-centered Internet of things (IoT) as well as M2M communications in the remote locations, with applications including satellite IoT device “wake-up,” IoT device localization, frequency as well as timing synchronization inter-satellite link tech, and the satellite system design.
These technologies, when combined, allow customers to receive better service, save energy, and communicate data more quickly and efficiently. Tiger-2, the constellation’s very first commercial IoT satellite, got launched in June 2021, behaved admirably during the LEOP (launch and early orbit phase), and currently in the payload commissioning phase. They’ll be used on the company’s next LEO satellite network.
“It is a strategic imperative for firms to get intellectual property rights, and NewSpace will be no exception. Suppose the patent applications in the United States and Europe go as planned. In that case, I anticipate OQ Technology to receive patents in Europe within the next 2 years, and considerably sooner in the US, “OQ Technology’s founder and CEO, Omar Qaise, stated.
“The technologies we’re employing vastly improve our ability to provide 5G IoT links in remote areas where terrestrial solutions fail or older satellite solutions are prohibitively expensive.” “Wake-up,” a smart power-saving function within terminal IoT device which allows the device to effectively wake up and connect with base station (satellite), is one of the innovations for the patent applications.
The ability to identify a terminal device utilizing stored data from base station(s) rather than a costly global positioning system is known as “terminal device localization.” “In the year 2017, OQ took the risk of creating its software stack from the ground up, relying on 3GPP standard, and executing its own satellite supporting algorithms,” said Qaise. “Having our stack and also being able to regulate the traffic and service quality for our users offers us a significant competitive advantage over other players that dependent on 3rd parties and new entrants who have yet to deliver.
Other available cell tower software stacks include highly proprietary technology developed by firms such as Nokia, Ericsson, and Huawei, that were unlikely to grant us access and allow us to adapt it for use in a satellite environment.” There are also “Inter-satellite links,” which keep the various base stations informed of one another and keep track of the terminal devices attached to the various base stations.
To overcome the Doppler effect (wavelength variations from moving objects) as well as timing misalignment issues, “timing synchronization” and “frequency synchronization” are used to synchronize communication and hence enhance signaling between the base stations and terminal devices. Last but not least, there’s a patent for the satellite system design and the network architecture for the mobile IoT communication between earth and space stations.
