Telstra, Ericsson, Intel complete “5G” data call using 3GPP New Radio

Australian network operator Telstra, Ericsson and Intel announced they have jointly completed the first end-to-end 3GPP non-standalone “5G” data call on a commercial network in a multi-vendor setup.   The trial at Telstra’s 5G Innovation Centre on Australia’s Gold Coast used licensed 3.5-GHz spectrum, and Ericsson’s “5G” New Radio, baseband and packet core solution, a Telstra SIM and the Intel 5G Mobile Trial Platform.  It involved a network connection to an Ericsson virtualized 5G packet core running on Ericsson’s network functions virtualization (NFV) infrastructure. The 5G slice was then connected into the existing Telstra 4G mobile network.

Ericsson and Intel jointly completed the first lab-based end-to-end non-standalone 5G data call earlier this month, and the live demonstration builds on this milestone.

“Demonstrating this 5G data call end-to-end using my own personal SIM card on Telstra’s mobile network is the closest any provider has come to making a ’true’ 5G call in the real world-environment, and marks another 5G first for Telstra,” Telstra group managing director for networks Mike Wright said.

Previous “5G” experiments have included the first 5G data call over 26-GHz spectrum, Australia’s first 5G connected vehicle trial and its first 5G mobile gaming demonstration.

“We continue to work with global technology companies Ericsson and Intel as well as global standards bodies to advance the deployment of commercial 5G capability in Australia,” Wright concluded.

Intel Next Generation and Standards vice president and general manager Asha Keddy said the tech giant would continue working on 5G use cases and trials ahead of the launch of Telstra’s 5G network in 2019.



One thought on “Telstra, Ericsson, Intel complete “5G” data call using 3GPP New Radio

  1. 3GPP New Radio (in release 15 spec) reallocates some existing LTE bands and introduces new mmWave bands up to 40 GHz. While initial 5G devices will implement some type of point-to-point wireless link, smartphone manufacturers are already planning the introduction of their products that contain multiple radios. Adding yet another radio adds new coexistence challenges that designers must address.

    5G NR mid-band (1 GHz to 6 GHz) and high-band (above 24 GHz) operate in the same or in adjacent spectrum to other wireless communications systems. With devices covering multiple bands, there is increased risk for sideband interference or new shared spectrum issues. 5G NR devices will need to operate adjacent to or even in the same spectrum as existing wireless communications systems without causing interference. Designers of 5G chipsets and components need to know the different types of coexistence interference issues, where coexistence interference is likely to occur, and how to test for coexistence interference.

    There are many types of coexistence interference, but two primary issues require new coexistence testing. The first involves testing in-band and out-of-band emissions and testing the impact of the 5G NR emissions on other radio signals. These tests are important because you must ensure that a 5G radio doesn’t cause interference with other radios in the device, with other radios signals in the channel, or with signals in an adjacent spectrum. Such testing is similar to 4G coexistence issues, but the increasing number of radios in a device and the increasing number operating bands where 5G NR will operate will compound the problem.

    Second, because a goal of 5G is to improve data throughput, shared spectrum will be a key feature in 5G. To operate simultaneously in a shared environment, new procedures and protocols must be developed to ensure successful operation in the environment. At the highest level, these policies specify that devices must listen before they talk. Specifically, a device needs to detect coexistence traffic and allocate or reallocate spectrum dynamically based on what it hears. This presents potential quality of service issues (QoS) issues for device users caused by latencies while the radio switches channels. This will require special tests not previously done on cellular devices.–Coming-to-5G-New-Radio
