A Singapore university’s attempt to develop vehicle-to-everything (V2X) solutions for smart vehicles met a roadblock: no unified testing solution was available …

Vehicle-to-everything (V2X) technology is a rising star in the field of smart vehicle technology.

To fully realize smart mobility, there are several technology challenges, including V2X, which in turn consists of dedicated short-range communication (DSRC) and cellular-V2X (C-V2X). However, a single unified V2X test solution does not currently exist. 

Singapore’s Nanyang Technological University (NTU) is currently conducting research on a reconfigurable transceiver system specifically for hybrid (DSRC+C-V2X) communication at 5.9 GHz ISM band. This also includes possible extension to the millimeter-wave (mmWave) frequency range using cost-effective complementary metal-oxide semiconductor (CMOS) technology.

In order to arrive at a unified test solution for their advanced research, the university has partnered with a test solutions provider for generating and analyzing both DSRC and C-V2X signals. This includes testing and validation requirements for multi-components and system-level specifications in V2X communication standards, as well as 5G signal generation and analysis in the mmWave frequency range and multiple-input and multiple-output (MIMO) mode.

As a result, the university has been able to generate accurate and full characterization of the newly-developed transceiver.

According to Associate Professor Boon Chirn Chye from the School of Electrical and Electronic Engineering, the lead investigator for the project, the school’s deep expertise in vehicular communications and integrated circuit designs, coupled with test solutions vendor Keysight‘s mmWave expertise and advanced solutions, “yielded valuable insights that helped in accelerating the development of hybrid V2X communications that will be test-bedded on the NTU Smart Campus.”

Said Ee Huei Sin, Senior Vice President and President of the Electronic Industrial Solutions Group, Keysight Technologies: “We are delighted to provide NTU with a wide range of our test and measurement solutions that enable their cutting-edge research. It’s another example of ongoing partnerships with universities to discover the next breakthrough in technology.”
