Qualcomm is displaying an interoperable 5G data connection this week at Mobile World Congress following a successful recent test of the technology.

The San Diego chip maker collaborated with Samsung and South Korean carrier KT to demonstrate multi-vendor 5G New Radio interoperability that complied with recently enacted 3GPP standards.

The test, conducted in Samsung labs using the tech giant's pre-commercial 5G base stations and prototype Qualcomm devices, established connections in the 3.5 GHz and 28 GHz bands and achieved multi-gigabit download speeds with latencies as low as 1 millisecond.

Company officials added that the end-to-end interoperability tests included “the essential components of the 5G NR air interface” — particularly “scalable 5G NR OFDM numerology, advanced 5G NR channel coding and modulation schemes, low-latency 5G NR slot structure and 5G NR control and data channel support for Massive MIMO and mobile mmWave.”

“As the industry works toward the goal of commercial launches of 5G NR products and networks in 2019, close collaboration among global mobile industry leaders on testing and successful trials are necessary to validate the technologies and continue to build and improve our capabilities,” Qualcomm President Cristiano Amon said in a statement.
