Nokia Qualcomm completed 5G lab test, look forward to the Winter Olympics and MWC it


Recently, Nokia and Qualcomm completed 5G NR link lab testing for 10 operators and expects to quickly apply their systems to field tests. The news made this month's Korea Winter Olympics and Barcelona World Mobile Congress a step closer to 5G commercial services.

 EETimes San Jose, Calif., Reports that Nokia and Qualcomm recently completed 5G NR link lab testing for 10 operators and hoped to quickly put their systems to the field for testing. The news brought the Korean Winter Olympics this month and the World Wide Congress (MWC) in Barcelona a step closer to 5G commercial services.
The two companies showcased a version of Nokia's AirScale base station and Qualcomm prototypes made at Nokia Labs in Oulu, Finland, which can operate on 5G NR links in the 3.5GHz and 28GHz bands. This FPGA-based system will serve as the basis for on-site testing of operators this year. The participating operators include Deutsche Telekom, Elisa, KT, LGU +, NTT DOCOMO, Optus, SK Telecom, Telia and Vodafone. Both Nokia and Qualcomm hope the trials will help them deploy various 5G services in China, Europe, South Korea, Japan and the United States next year.
Qualcomm and Nokia rival Ericsson conducted a competitive experimental demonstration in the same frequency band after the industry completed the 5G NR specification in December last year. His partners include AT & T, NTT Docomo, Orange, SK Telecom, Verizon and Vodafone. In November last year, China Mobile Lab tested ZTE's prototype base station and Qualcomm's test cell phones.
Later this week, South Korea will show a pre-standard 5G network using Intel and Samsung equipment at the PyeongChang Winter Olympics. Phil Twist, head of mobile marketing at Nokia, told a press conference prior to MWC that the MWC conference in Spain later this month will cover the topic "5G Commercialization - How to Get Return on Investment and Integrate AI into the Network" .

Nokia will show at MWC the latest version of its 5G ReefShark chipset designed for the base station. The company designed the AirScale base station to support the ReefShark module, and its traffic capacity can be upgraded from 28Gbps LTE to 84Gbps 5G.
Multiple modules with a 10nm chipset can work together and the AirScale backplane will support throughput of up to 6Tbit / s. Nokia said there are currently up to 30 customers using ReefShark, some plans to deploy this year.
On handsets, suppliers are expected to demonstrate devices that support up to 20 data streams using a 4x4 MIMO antenna and up to five 20MHz carriers. This kind of technology will push advanced LTE and 5G to surmount the present gigabit LTE mobile broadband business, some operators are very interested in and even plan to launch in the autumn of 2018.
Only a whirlwind, in order to allow Qualcomm in the mobile baseband chips ahead of competitors Intel. In November last year, Intel announced plans to support CDMA and gigabit speeds in cellular modems in 2018 and up to 1.6Gbps in 2019.
In the 5G competition, the new NR specification is "Everyone is waiting ... We are currently running the first variant of the variant and more variants will appear in the future," Twist said.
There will be a lot of options for RF chips and backhaul. For example, Nokia is developing base station radios that use high-capacity three-carrier aggregation and beamforming radios for high bandwidth. On the return trip, it is designing microwave, IP and optical options.
With the 5G radio standard set, the next big agenda item is network layering. Twist said the final version of this version of the virtual radio is still under discussion and is expected to have results by June of this year.
