SK Telecom, Ericsson, and Qualcomm will conduct interoperability tests and field trials based on 5G New Radio (NR) standards together, the companies have announced.

The trials will be compliant to 5G NR specification, the standard set by globlal standard-setting body 3GPP, for the coming fifth-generation network.

It will drive the mobile ecosystem towards validation and commercialization of the standard in scale, SK Telecom said.

The companies will utilize wide bandwidths available at higher frequency bands that will help achieve gigabit per second data transfer rates.

Telcos are expected to use ultra-high frequncy bands for 5G networks for high data transfer rates.

Multiple Input Multiple Output (MIMO) antenna technology that meets the standard with adaptive beam forming and tracking techniques, which will allow sustained communications at higher frequency bands, will also be tested.

The tests will begin in South Korea in the second half of 2017. Designs for radio stations, equipment, and handsets have begun now.

SK Telecom and Ericsson launched a pilot 5G network in February this year.

Viability tests of Ericsson's pre-commercial 5G technology

In the European race to make 5G a reality by the year 2020, time and opportunity are of the essence. At the Madrid-based 5TONIC Lab, Ericsson is already conducting viability tests of a novel networking technology that aspires to enable the prompt rollout of 5G networks.

5TONIC, an open research and innovation laboratory focused on fifth generation (5G) technologies located at IMDEA Networks Institute, is currently hosting a groundbreaking testbed of the European research project 5G-Crosshaul. A battery of tests will be performed from September 7th to October 10th to evaluate technology developed by Ericsson, one of the lab members. The technology now being tested consists of an integrated fronthaul/backhaul network, also known as the "Crosshaul" network, in which CPRI (Common Public Radio Interface) and packet based information are homogeneously transported over a DWDM (Dense Wavelength Division Multiplexing) network and integrated optical/packet switches.

Mobile data traffic is forecasted to increase 11-fold between 2013 and 2018. 5G networks serving this mobile data tsunami will require fronthaul and backhaul solutions between the RAN and the packet core, which are capable of dealing with this increased traffic load while fulfilling new stringent 5G service requirements, all in a cost-efficient manner. In the context of the 5G-Crosshaul research effort, Ericsson's technology aims to provide a stepping stone towards the creation of the novel transport network that is needed to make the promise of a thousand times more network capacity a tangible actuality. The crosshaul architecture, with a unified data-plane, allows network providers to reduce their CapEx and OpEx, which is key to adopt the upcoming 5G era.

At this early stage, 5G application scenarios are still being defined, and lab work is required to outline the suitable infrastructure that will enable the launch of 5G communications, services and applications. 5TONIC enables its partner companies to test and proof advanced 5G developments prior to their market launch, speeding up the innovation process and the transfer of research results from the drawing board to production on the basis of their technical and commercial viability. The current testbed is an early effort to perform a realistic evaluation of the capabilities of a concrete pre-commercial 5G technology and establish its actual chances of becoming a building block of the 5G era.

Telstra, Ericsson & Qualcomm Reach 1Gbps using 256QAM & 4x4 MIMO on Network

Telstra in partnership with Ericsson and Qualcomm showcased download speeds of 979Mbps and upload speeds of 129Mbps using a single device on Telstra’s live network.

Early this year, TeliaSonera Norway and Huawei conducted an LTE Advanced Pro (4.5G) testing over its live commercial mobile network, hitting similar speeds in Oslo, Norway. Swisscom also achieved close to 1Gbps in a testing on its 4G network in April.

The tests were conducted using carrier aggregation, 64 Quadrature Amplitude Modulation (QAM) uplink, 256 QAM downlink, and 4x4 Multiple-Input Multiple-Output (MIMO) technologies using Ericsson's Baseband 5216 hardware, and Qualcomm's Snapdragon X16 LTE modem test device.

According to Telstra, increasing social sharing and video uploads are driving the need for higher uplink performance for smartphone users across the network. Improving uplink speeds is also important for remote and onsite workers use of enterprise cloud applications for unified communications, especially video-conferencing apps, it added.
