Første 5G datakald ved brug af 2,5 GHz og Massive MIMO

Den amerikanske mobile netværksoperatør Sprint har gennemført verdens første 5G datakald ved brug af 2,5 GHz frekvensbåndet og Massive MIMO i et kommercielt netværk (in english).

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.

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.

- This is a big step forward - Sprint 5G is now out of the lab and in the field as we prepare for our commercial launch in the first half of this year, says Dr. John Saw, Sprint's Chief Technology Officer.
- We're making great progress towards giving Sprint customers the first mobile 5G experience in nine top cities with the first 5G smartphone in the U.S.

- Nokia is pleased to work on another 5G first with Sprint and Qualcomm, adds Mike Murphy, Chief Technology Officer for North America, Nokia.
- 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."

- The announcement marks a major milestone in 5G commercialization using sub-6 GHz spectrum, which provides wide area and high-performance connectivity, says Durga Malladi, Senior Vice President and General Manager, 4G/5G, Qualcomm Technologies, Inc.

- We look forward to continue working with Sprint and Nokia in bringing high-capacity and multi-gigabit 5G networks to consumers in 2019.

The successful test at a commercial Sprint cell site follows earlier 5G milestones by the company. In December, Sprint completed its first 5G NR data transmissions inside its lab in Reston, Va., using its 2.5 GHz spectrum, Massive MIMO radios from both Nokia and Ericsson, and a mobile smartphone form-factor test device from Qualcomm Technologies.

Sprint 5G launching in first half of 2019

Sprint is executing its 5G strategy with 2.5 GHz spectrum and Massive MIMO technology to launch its blazing-fast service beginning in nine top cities in the first half of 2019. They include Atlanta, Chicago, Dallas, Houston, Kansas City, Los Angeles, New York City, Phoenix and Washington, D.C.

From the start, the company is designing mobile 5G footprints covering these downtown metros. Using its super-fast, mid-band 2.5 GHz spectrum, Sprint plans to offer contiguous coverage in the downtown area of these cities for its highly mobile, on-the-go customers.

Sprint's 5G build out is well under way with hundreds of Massive MIMO radios deployed last year. Massive MIMO is a breakthrough technology that dramatically improves the capacity of Sprint's LTE Advanced network with equipment that is software upgradable to 5G. Sprint's 64T64R Massive MIMO radios support split-mode, enabling the company to offer LTE and 5G simultaneously on the same radio.

Initial results from early deployments show Massive MIMO is driving a 4X average increase in capacity and speed with peak increases up to 10X over LTE. With Massive MIMO at the foundation of its mobile 5G service, Sprint can keep meeting its customers' demand for unlimited data and high-bandwidth applications.

5G promises new levels of innovation and progress to connect people, places and the billions of things Sprint customers do with blazing-fast speed and ultra-reliable wireless connectivity. Sprint customers will experience mobile 5G with the first 5G smartphone in the U.S. from Sprint and LG. Sprint's 5G device portfolio will also include a 5G mobile smart hub from HTC and a 5G smartphone from Samsung.
