Qualcomm Technologies and Ericsson announced the successful completion of a 3GPP Rel-15 spec compliant 5G NR over-the-air (OTA) call over sub-6 GHz bands on a smartphone form factor mobile test device.

The OTA call was conducted in the Ericsson Lab in Stockholm, Sweden on the 3.5 GHz band. Similar to the companies’ first OTA calls performed using millimeter wave (mmWave) in both 28 and 39 GHz spectrum bands, which occurred in September 2018, this sub-6 GHz call utilized Ericsson’s commercial 5G NR radio AIR 6488 and baseband products and a mobile test device powered by the Qualcomm Snapdragon X50 5G modem and RF subsystem.

In December 2017, Ericsson and Qualcomm Technologies announced interoperability development testing (IODT) to help pave the way for commercial launches of 5G NR standard-compliant infrastructure, smartphones and other mobile devices in the first half of 2019. The successful 5G OTA calls using both sub-6 GHz and mmWave bands are critical milestones in the commercialization process as operators and OEMs around the world can now utilize the companies’ products to conduct their own tests in their labs and the field.

Per Narvinger, Head of Product Area Networks, Ericsson
Achieving interoperability on different spectrums shows the strength of the 5G ecosystem. Together with Qualcomm Technologies, we’ve successfully tested 5G NR on 39, 28 and now, 3.5 GHz band.

Durga Malladi, SVP, Engineering and GM, 4G/5G, Qualcomm Technologies
Sub-6 GHz spectrum is instrumental to the global 5G NR rollout as it will provide wide area, high performance connectivity and has been allocated and auctioned in numerous regions around the world, including the US, Korea and Europe, with others to follow shortly.
