Sprint tested 5G in 2.5 GHz in its live network in San Diego, utilized equipment from Nokia and Qualcomm Technologies
Sprint completed what it claims to be the world's first over-the-air 5G data transmission using 2.5 GHz and massive MIMO on its live commercial network.
The test was carried out with Nokia and Qualcomm Technologies, the carrier said.
The field test, conducted on Sprint's commercial network in San Diego, used global 5G standards on a commercial 3GPP 5G New Radio (NR) network with Sprint's 2.5 GHz spectrum, Nokia's dual-mode AirScale massive MIMO radio and a mobile smartphone form-factor test device powered by the Qualcomm Snapdragon X50 5G modem and antenna modules with integrated RF transceiver, RF front-end and antenna elements.
Sprint said that the test "demonstrated a seamless transition of connectivity between Sprint's 4G LTE Advanced and 5G network," while streaming YouTube videos, conducting Skype audio and video calls and sending and receiving instant messages.
"By using 2.5 GHz for 5G, existing sites nationwide can be re-used, with indoor coverage as well. This first standards-based call is thus a critical step towards Sprint's offering of a 5G service to its customers," said Mike Murphy, CTO for North America, Nokia.
