The technology allows users to validate the protocol signaling and Radio Frequency (RF) performance of 5G NR mobile devices in a laboratory environment. The mmWave over-the-air (OTA) test capabilities combine network emulation with an anechoic chamber, such as Keysight’s Compact Antenna Test Range (CATR) to use the chamber as an indirect far field test methodology.
"Keysight’s expertise in mmWave and 5G test capability in OTA environments enable us to accelerate our 5G commercialization plans and ensure that new 5G mobile devices will operate reliably on our network." said Toshiyuki Futakata, vice president and general manager of Communication Device Development Department, NTT DoCoMo. "Collaboration with Keysight includes refining highly-specialized technology necessary for testing 5G devices in an OTA environment.”
Keysight is also collaborating with NTT DoCoMo to develop specific test scenarios for their mobile ecosystem to ensure new 5G mobile devices will operate as expected on their network. This enables NTT's ecosystem to reduce R&D efforts and accelerate market introductions of new 5G mobile devices.
The company has been using 5G Protocol R&D and RF Design Verification Toolsets, which both support the 3GPP Release 15 5G NR standard, working on 5G technology in 2015 to develop mmWave technology for effective deployment of enhanced mobile broadband (eMBB) services in support of key 5G use cases.
"We are excited to be closely collaborating with NTT DoCoMo to meet their strategic goals of successful deployment of 5G commercial services by 2020," said Kailash Narayanan, vice president and general manager of Wireless Test business at Keysight Technologies. "Keysight’s first-to-market 5G solutions, breadth of our solution portfolio and metrology expertise are enabling leading mobile operators and their ecosystems to accelerate 5G development and deployment."
