Ericsson and Qualcomm have held their latest 5G data call, this time turning attention to the 28GHz band.
The call, using the 5G New Radio standards, was held at Ericsson's lab in Kista. It used Ericsson's 5G New Radio equipment and basebands, as well as a test device equipped by Qualcomm's Snapdragon X50 5G modem.
Ericsson cited figures from GSMA Intelligence which said more than 20 operators were holding trials using the 28GHz band. It is expected that that frequency will be central to European, American and South Korean operators' 5G plans.
It follows both companies holding a similar downlink data call in early September that used the 39GHz band. They also previously tested interoperability tests on the 3.5GHz spectrum band.
Ericsson said access to high frequency bands was vital to provide the ultra-high speeds and low latencies required for 5G.
Thomas Noren, Head of 5G Commercialisation at Ericsson, said: “By adding 28 GHz to the list of spectrum bands supported and tested by our equipment for initial 5G launches, we make it easier for our customers to roll out early 5G services to their users. This is made possible by our collaborative efforts with key partners to build a solid 5G ecosystem.”
