 Nokia has successfully carried out the world’s first connection based on the Verizon fifth-generation (V5G) technical forum (TF) interface, which is known as the industry-agreed specification for prestandard 5G applications.
The test adds another key component to the development of 5G technologies and the execution of the first 5G applications, demonstrating the ability to provide fast-paced implementation, according to early standards, including device interoperability. At the end of 2016, Nokia introduced 4.5G Pro and announced plans for 4.9G, providing operators with the critical increases to capacity and speed that will be needed for future 5G operations.
The world’s first 5G connection using the V5GTF draft specification took place in a laboratory environment in Oulu, Finland, on 23 December 2016. The connection was made possible by Nokia’s commercially available V5GTFready AirScale radio access with the Nokia AirFrame data center platform running on Intel architecture, using also the Intel 5G mobile trial platform as an end-user device.
Data transmission on a 5G network is a significant milestone in the commercialization of the new wireless 5G technology. This is especially true for the cross-industry efforts being made by all players in the 5G ecosystem to standardize all aspects of 5G ahead of full commercial service launches that are expected to begin in 2020 on Third Generation Partnership Project (3GPP) New Radio (NR).
The 5G trial marked a further milestone in Nokia’s momentum to make 5G a commercial reality. It also indicated yet another Nokia contribution to the evolution of communications: the first Global System for Mobile communications (GSM) call was made in Finland more than 20 years ago using a network built by Nokia.
This tradition continued with the world’s first third-generation (3G) voice call, on a commercial 3GPP system in Finland in 2001, and then with the world’s first long-term evolution (LTE) call via commercial software in Germany in 2009.
Ericsson and Qualcomm Technologies, a subsidiary of Qualcomm Incorporated, announced that they are working with Vodafone to test 5G interoperability and conduct an over-the-air field trial. The trial will be based on the 5G NR specifications being developed by 3GPP, which will form the basis of the global 5G standards.
The trial intends to drive the mobile ecosystem toward validation of 5G NR technologies, which will enable operators to test 3GPPstandard-compliant 5G NR infrastructure and devices at scale. It will take place in the United Kingdom, and will showcase 5G NR technologies that utilize wide bandwidths to increase network capacity and achieve multigigabit-per-second data rates.
Applicable to both existing licensed bands and new bands in sub-6 GHz, 5G will be important for meeting the increasing connectivity requirements for emerging consumer mobile broadband experiences such as virtual reality, augmented reality, and connected cloud services.
The trial will make use of advanced 3GPP 5G NR technologies, including massive multiple-input, multiple-output (MIMO) antenna technology; adaptive self-contained time division duplex (TDD); beamforming techniques; scalable orthogonal frequency division multiplexing (OFDM)-based waveforms to support wider bandwidths; advanced coding and modulation schemes; and a new flexible framework design. The 3GPP 5G NR standard-based interoperability testing and trials will start in the second half of 2017.
