Check and Measurement: Gogo Enterprise Aviation checks its 5G software program utilizing digital flight simulator


Gogo Enterprise Aviation says that it’s utilizing a sophisticated digital flight simulator that was constructed by its radio frequency engineering staff, to emulate the radio channel in an airborne setting to be able to check its 5G software program—earlier than it will get its palms on the precise 5G chip that may allow its service.

“By leveraging proprietary info and flight information, Gogo can examine efficiency of the radio frequency, making an allowance for elements like doppler, altitude, flight routes, angle of method, beam-forming know-how and different parameters, all vital elements to grasp as Gogo optimizes the 5G service and onboard connectivity efficiency,” the corporate mentioned in a launch, including that the emulation permits end-to-end testing of the system and maturation of the software program earlier than the corporate proceeds to flight checks. “With the 5G chip nonetheless in manufacturing, the RF staff considered a digital flight simulator as a viable option to accomplish testing and fine-tuning of the software program with out the precise chip,” Gogo famous in a weblog submit.

Gogo Enterprise Aviation, which says it has already put in an air-to-ground community of 150 towers to assist the service, expects to begin delivering its “Gogo 5G” later this 12 months. Gogo Enterprise Aviation solely serves the non-public aviation market; the corporate offered its industrial airline enterprise to Intelsat in 2020. The corporate is the topic of a patent infringement lawsuit by SmartSky over the proposed 5G air-to-ground service. That case is ready to go to trial in April 2025, in response to SmartSky. In January of this 12 months, Gogo acquired an appellate courtroom ruling which is able to permit it to start promoting its service regardless of the continued go well with.

Within the weblog submit, Gogo Enterprise Aviation mentioned that utilizing the digital flight check lab, its check staff “will make 5G calls and switch information, checking efficiency to optimize the 5G service and onboard connectivity efficiency. Over the subsequent a number of weeks, the staff will simulate lots of of 5G flights with totally different geographical positions and altitudes, angles of arrival, beamforming, doppler, speeds, and distances to Gogo’s ground-based 5G towers.”

“The digital flight simulator our staff has constructed is an instance of what we do finest: innovate,” mentioned Sergio Aguirre, president and COO for Gogo. “Our groups have designed an exceptional methodology for validating and maturing our 5G software program and {hardware} to a vital diploma earlier than the ultimate 5G chip is in our palms.”

-The Satellite tv for pc 2024 present was held in Washington, DC this week and the satellite tv for pc and mobile industries are conserving an in depth eye on the implications of requirements convergence in 5G Non-Terrestrial Networks, or NTN. (See RCR Wi-fi Information protection right here and right here.) Keysight Applied sciences introduced its dwell demonstration of Capgemini’s Open RAN CU/DU with NTN capabilities to the satellite tv for pc present. That demo was first offered at Cell World Congress Barcelona, with Keysight working with Capgemini to confirm the latter’s 5G New Radio Open RAN central unit (CU) and distributed unit (DU) framework that helps 3GPP Launch 17 NTN performance. The validation depends on Keysight’s UeSIM UE Emulation RAN to emulate NTN units and Keysight’s Propsim Channel Emulator to play the function of a constellation of LEO satellites and emulate actual community site visitors, in addition to radio situations together with delay and doppler shift which affect connections between a satellite tv for pc and units under.

“Capgemini’s 5G NTN software program framework is particularly crafted to expedite the implementation of numerous satellite-based communication techniques by the Satcom business,” mentioned Rajat Kapoor, head of software program frameworks at Capgemini. “The validation and interoperability of our 5G NTN software program framework with key collaborators resembling Keysight are essential milestones, enabling swift progress to fulfill the escalating demand for 5G NR NTN deployment. This consists of catering to totally different deployment fashions like clear or regenerative, and broadband and IoT use circumstances, making certain adaptability to varied eventualities.

Peng Cao, VP and GM for Keysight’s Wi-fi Check Group, mentioned that Keysight’s NTN portfolio “presents cutting-edge simulation and emulation capabilities for UEs, mobility mixed with channel and orbit modeling required to check numerous satellite tv for pc techniques implementations within the lab setting underneath real-world situations. By working carefully with companions resembling Capgemini, Keysight helps to speed up Open RAN deployments for non-terrestrial networks.”

-In Keysight information on the bottom, the corporate mentioned that it has developed the business’s first working 1.6 terabit Layer 2 site visitors technology and measurement system, which it demonstrated with Credo Semiconductor in a joint testbed. The demonstration, Keysight mentioned, “supplies proof that 1.6T Ethernet pace is feasible and that its efficiency could be measured.”

Ram Periakaruppan, VP and GM for community check and safety options at Keysight, mentioned that 1.6T Ethernet “addresses the demand for extra community bandwidth and information throughput, pushed partly, by ever-increasing AI workloads throughout the community infrastructure. The 1.6T Ethernet Layer 2 site visitors technology and evaluation demonstration strikes the needle ahead to allow growth of 1.6T units and all the networking tools ecosystem. Keysight’s Layer 2 and FEC check and measurement techniques are additionally important to the success of the eventual deployment of 1.6T succesful networking units and tools.”

Rohde & Schwarz has opened a brand new service facility in Milpitas, California. The check tools firm’s new location will present calibration and changes to R&S tools as much as 67 GHz initially, with plans to increase the situation’s capabilities. For now, the Milpitas location will present complimentary packing and transport of kit with a spread above 67 GHz, or any items that want restore.

Wes Fisher, North American director of service at Rohde & Schwarz, mentioned that “Even the most effective devices require common calibrations and changes,” and that the growth “addresses constructive buyer demand for our calibration service and supplies higher response time for service requests.”

Tektronix has launched its new Tektronix CAN XL (Controller Space Community Prolonged Size) protocol decoder aimed toward supporting automotive transport. CAN XL is the most recent addition to Controller Space Community (CAN) protocols, and the decoder works on Tek’s 4, 5, 6 Collection MSO Oscilloscopes and presents options together with error detection, evaluation and debugging of timing and protocol headers, in response to the corporate. T

The CAN XL protocol decoder is on the market now globally as an optionally available replace, and can be out there as a part of Tek’s software software program bundles for automotive and serial bus assist.
