Gogo Business Aviation uses an advanced virtual flight simulator built by its radio frequency engineering team to emulate radio channels in the aircraft environment to test its 5G software before getting actual 5G chips. It states that it is rated. This will enable the service.
“By leveraging proprietary information and flight data, Gogo can check radio frequency performance, taking into account factors such as Doppler, altitude, flight route, approach angle, beamforming technology, and other parameters. All these important factors need to be understood as Gogo optimizes “5G services and improves in-flight connectivity performance,” the company said in a release, adding that emulation helps improve the system’s performance before proceeding to flight testing. It added that it will enable end-to-end testing and software maturation. “With the 5G chip still in production, the RF team considered the Virtual Flight His Simulator as a viable way to test and fine-tune the software without using the actual chip.” Gogo said in a blog post.
Gogo Business Aviation says it has already installed an air-to-ground network of 150 towers to support the service and plans to begin offering “Gogo 5G” later this year. Gogo Business Aviation serves the civil aviation market only. The company sold its civil aviation business to Intelsat in 2020. The company is the subject of a patent infringement lawsuit by SmartSky over its proposed 5G air-to-ground service. The case is scheduled to go to trial in April 2025, according to SmartSky. In January, Gogo received an appeals court ruling allowing it to begin selling its services despite ongoing litigation.
Gogo Business Aviation said in a blog post that its virtual flight test lab will be used by its test team to “make 5G calls, transfer data, and check performance to optimize 5G services and in-flight connectivity performance.” Ta. Over the next few weeks, the team will simulate hundreds of his 5G flights using different geographic locations and altitudes, angle of arrival, beamforming, Doppler, speed, and distance to Gogo’s ground-based 5G tower. . ”
“The virtual flight simulator that our team built is an example of what we do best: innovation,” said Sergio Aguirre, President and COO of Gogo. “Our team has designed an incredible way to validate and mature the 5G software and hardware to a critical level before the final 5G chip reaches our hands. ”

-The satellite 2024 The show takes place this week in Washington, DC, as the satellite and mobile phone industries closely monitor the impact of standards convergence in 5G non-terrestrial networks (NTN). (See RCR Wireless News articles here and here.) keysight technology held a live demonstration of capgemini’s Open RAN CU/DU with NTN functionality to satellite show.That demo was first announced Mobile World Congress BarcelonaKeysight is collaborating with Capgemini to validate Capgemini’s 5G New Radio Open RAN central unit (CU) and distributed unit (DU) framework supporting 3GPP Release 17 NTN capabilities. This validation tested Keysight’s UeSIM UE Emulation RAN, which emulates NTN devices and serves as a constellation of LEO satellites, including the actual network traffic and delays and Doppler shifts that affect connectivity between the satellites. It relies on Keysight’s Propsim Channel emulator to emulate radio conditions. and the following devices.
“Capgemini’s 5G NTN software framework is specifically created to facilitate the implementation of diverse satellite-based communication systems by the satellite communications industry,” said Rajat Kapur, Head of Software Frameworks at Capgemini. states. “The validation and interoperability of our 5G NTN software framework with key collaborators such as Keysight is an important milestone and enables rapid progress to meet the growing demand for 5G NR NTN deployments. This includes support for different deployment models such as transparent or regenerative, broadband and IoT use cases, ensuring adaptability to different scenarios.“
Peng Cao, vice president and general of Keysight’s Wireless Test Group, said that Keysight’s NTN portfolio provides “the most advanced UE solutions needed to test diverse satellite system implementations in real-world lab environments. It offers mobility combined with advanced simulation and emulation capabilities, channel and trajectory modeling.” -World situation. Keysight is working closely with partners such as Capgemini to help accelerate open RAN deployments for non-terrestrial networks. ”
-In local news, Keysight announced that it has developed and demonstrated the industry’s first practical 1.6 terabit Layer 2 traffic generation and measurement system. credo semiconductor In a collaborative testbed. Keysight said the demonstration “proves that 1.6T Ethernet speeds are possible and that performance can be measured.”
Ram Periakaruppan, vice president and GM of network test and security solutions at Keysight, said 1.6T Ethernet will allow for “more network bandwidth, driven in part by the ever-increasing AI workloads within the network infrastructure. It addresses the demand for breadth and data throughput.” The demonstration of 1.6T Ethernet Layer 2 traffic generation and analysis is a major step forward in enabling the development of the entire 1.6T device and networking equipment ecosystem. Keysight’s Layer 2 and FEC test and measurement systems are also essential to the successful eventual deployment of 1.6T-capable networking devices and equipment. ”
–Rohde Schwarz has opened a new service facility in Milpitas, California. The test equipment company’s new location will initially offer calibration and adjustment of R&S instruments up to 67 GHz, but it plans to expand the location’s capabilities. At this time, our Milpitas location offers free packaging and shipping for equipment in the range above 67 GHz or units that require repair.
“Even the best equipment requires periodic calibration and adjustment,” said Wes Fischer, Rohde & Schwarz Director of North American Services. “Response time to requests will be reduced.”
–Tektronix Tektronix has launched a new CAN XL (Controller Area Network Extended Length) protocol decoder aimed at supporting automotive transportation. According to the company, CAN XL is the latest addition to the Controller Area Network (CAN) protocol, and the decoder works with Tek’s 4, 5, and 6 series MSO oscilloscopes to provide timing and protocol header error detection, analysis, and It provides functions such as debugging. T
The CAN XL protocol decoder is now available worldwide as an optional update and as part of Tek’s application software bundles supporting automotive and serial buses.
