Ericsson Radio 4480 Ericsson Radio 4480

Ericsson, in partnership with Telstra, announced the first successful deployment of Radio 4480 with 5 radio access technologies at Ballarat, Victoria.

Ericsson says the innovative radio solution simplifies the management and evolution of multiple generations of technology on Telstra base station sites in both metro and regional areas, by simultaneously supporting five key 3GPP radio access technologies of 3G, 4G, 5G, Cat-M and NB-IoT across two spectrum bands, using the Ericsson Spectrum Sharing solution. The dual-band multi-technology capability of the Radio 4480 provides Telstra with a lower installation footprint while also delivering improved energy efficiency, future proofing, and sustainability.

This solution is the first application of its kind, with 4G, 5G, Cat-M and NB-IoT dynamically sharing the same radio carrier enabled by Ericsson Spectrum Sharing. In addition to Radio 4480, this industry leading solution is now also available on other Ericsson Radio System FDD radios, Ericsson said.

Ericsson states that the efficiency of the new Radio 4480 will help Telstra deliver expanded 5G coverage for customers in both the cities and especially in regional areas. As the Radio 4480 also supports existing 3G, 4G and IoT services, Telstra will be able to deliver the benefits of 5G earlier while maintaining existing services customers rely on today.

With Telstra planning to close the 3G network (~2024), the Radio 4480 with 5 radio access technologies will allow 3G spectrum to be reconfigured for 5G via simple software configuration changes and no return to site, Ericsson says.

The new Radio 4480 with 5 radio access technologies will support Telstra’s Band 28 (700MHz) for 4G, 5G, Cat-M and NB-IoT with Ericsson Spectrum Sharing, and Band 5 (850MHz) for 3G and 5G.

More on Ericsson spectrum sharing is available here, including a video highlighting spectrum sharing on Telstra's network.

Ericsson head of Australia and New Zealand Emilio Romeo says, “This latest innovation with Telstra reinforces how we are continuing to lead technological innovation on a global scale. We share Telstra’s long-term commitment to providing Australians in regional and rural communities with the best coverage and the latest technologies and we are proud to be able to provide a solution that combines deployment efficiency with the best Telstra customer experience.”

Telstra network engineering director customer access Chris Meissner says, “With our 5G network now reaching more than 75% of Australians, this innovation will ensure that we can continue to provide the best coverage possible to all communities. Ericsson’s Radio 4480 with 5 radio access technologies support will allow us to grow 5G coverage in an efficient and scalable manner, whilst maintaining existing services customers rely on today. This will ensure more Australians can benefit from the emerging digital economy that 5G helps to deliver.”

  • TPG Telecom and Telstra offering free calls to Tonga

    TPG Telecom and Telstra are making calls to Tonga free-of-charge to allow those in Australia with family and friends in to the Pacific Island nation to connect.

    TPG Telecom says it is making mobile phone calls to Tonga free-of-charge across its family of brands for the next two weeks to help customers reconnect with loved ones in the Pacific Island nation.

    TPG Telecom is now allowing customers across its Vodafone, Kogan and Lebara brands to make free-rated standard mobile calls to Tonga for two weeks starting Friday 21 January and ending on the night of Thursday 3 February 2022.

    TPG Telecom said it's other brands, including TPG, iiNet, Westnet and Internode will also allow free standard calls to Tonga between the same dates. A small number of customers may still see charges related to Tonga calls during this period, in which case, TPG Telecom invites them to please contact their service provider for a full credit.

    {loadposition chris08}

    Telstra group executive consumer and small business Michael Ackland said, "We want to help how we can, so we’re making it easier to get in touch and to stay on the phone with loved ones. To do this we’ll be waiving charges for calls to Tonga from Telstra home phones and post-paid mobiles from midnight tonight (Friday) for the next seven days. This offer isn’t available for pre-paid mobile calls at this stage, but we’ll be monitoring the situation and will extend this offer – and the time it’s available – if needed."

    TPG Telecom general manager products and devices Arthur Panos said, “We are heartbroken to see the tragic events that have taken place in Tonga, and to see the ripple effect it has had on the people of Tonga, Tongan Australians and the worldwide Tongan community.

    “Our thoughts are with all those affected by this disaster, and we hope this small gesture to help our customers reconnect will provide some support and comfort,” Panos concluded.

    Telstra is also working with Digicel Tonga to restore connectivity, Ackland commented,  "While we haven’t completed our acquisition of Digicel Pacific yet, we’re in regular contact with the team to offer our support. Fortunately, the Digicel Tonga team are all OK.

    "We have teams from across the business working with the Digicel Pacific technical team on a satellite communications solution to help restore some communications.

    "We’ve worked alongside the Australian Government to get the first batch of satellite equipment shipped on an RAAF flight, which has arrived and another shipment is on the way. This has helped the Digicel Tonga team start to progressively restore services, which is why we’re now able to offer free calls," Ackland concluded.

    Infrastructure within Tonga has been damaged, so while the two carriers have both stepped up admirably to support customers, calls may not get through until adequate capacity between Australia and Tonga is established and the services in Tonga are restored.   Please retry later if you fail to initially connect.

  • US 5G operators agree to delaying C-band deployment near airports
    in 5G

    Tensions rise between US mobile operators and the airline industry over the deployment of 5G in the C-band, requiring the White House to step in and negotiate a path forward.

    AT&T and Verizon spent billions on obtaining spectrum last year. In December 2021, the two carriers agreed to a 6-week pause on the deployment of C-band 5G to allow testing to ensure 5G C-band didn't interfere with airline safety systems. As this pause period came to a close, the airline industry has protested vigorously to the White House, FAA, FCC and other bodies regarding their concerns around potential interference to navigation systems resulting in possible safety issues.

    In another agreement, brokered by the White House, Verizon and AT&T have agreed to delay the 5G deployment around key airports and to work with the airline industry to ensure 5G can safely co-exist with air systems.

    US President Biden said, "I want to thank Verizon and AT&T for agreeing to delay 5G deployment around key airports and to continue working with the Department of Transportation on safe 5G deployment at this limited set of locations. This agreement will avoid potentially devastating disruptions to passenger travel, cargo operations, and our economic recovery, while allowing more than 90 percent of wireless tower deployment to occur as scheduled.

    {loadposition chris08}

    "This agreement protects flight safety and allows aviation operations to continue without significant disruption and will bring more high-speed internet options to millions of Americans. Expanding 5G and promoting competition in internet service are critical priorities of mine, and tomorrow will be a massive step in the right direction.

    "My team has been engaging non-stop with the wireless carriers, airlines, and aviation equipment manufacturers to chart a path forward for 5G deployment and aviation to safely co-exist – and, at my direction, they will continue to do so until we close the remaining gap and reach a permanent, workable solution around these key airports, the US President concluded.

    FCC chairwoman Jessica Rosenworcel said, “Next-generation 5G technologies will be the backbone of our economic future. Today's agreement makes it possible to bring this technology to millions more consumers and businesses throughout the country starting tomorrow using the C-band.

    "This is welcome news because we know that deployment can safely co-exist with aviation technologies in the United States, just as it does in other countries around the world. The FAA has a process in place to assess altimeter performance in the 5G environment and resolve any remaining concerns. It is essential that the FAA now complete this process with both care and speed,” Rosenworcel concluded.

    In a statement Verizon said, “Verizon is proud to lead the nation in 5G. Tomorrow, Verizon will launch its 5G Ultra Wideband network which will enable more than 90 million Americans to experience the transformative speed, reliability and power of this game-changing network on the go or in their homes or businesses. Americans have been clamouring for 5G and tomorrow we will deliver it. As the nation’s leading wireless provider, we have voluntarily decided to limit our 5G network around airports.

    "The Federal Aviation Administration (FAA) and our nation’s airlines have not been able to fully resolve navigating 5G around airports, despite it being safe and fully operational in more than 40 other countries. Thanks to the best team in the industry for delivering this technology which promises a revolutionary next step in wireless communications including tremendous benefits for our nation," Verizon concluded.

    From the tone of the Verizon release they aren't happy with the situation. The delay in launching C-band 5G has no doubt cost the mobile carrier significantly, they purchased the spectrum in good faith from the FCC on the basis that it was deployable from December last year.

    Meanwhile a number of international airline carriers have suspended flights to some US airports. Emirates said it would pause flights into the following airports: Boston, Chicago O'Hare, Dallas Fort Worth, George Bush Intercontinental in Houston, Miami, Newark, Orlando, San Francisco and Seattle.

    There is also tension between the FAA and the airline industry as the FAA moves to prove that C-band 5G does not interfere with airline systems. This needs the cooperation and support of the airline industry, an industry feeling the pinch of several lean years due to COVID.

  • Vodafone UK switches on first 5G OpenRAN site
    in 5G

    Vodafone has switched on the UK’s first 5G OpenRAN. The site in Bath is the first of 2,500 5G and 4G OpenRAN sites that Vodafone has committed to, and a major step in supporting the Government’s ambition to accelerate the development of the OpenRAN ecosystem.

    Last month, the UK Government and telecoms operators announced shared ambitions to expand support for the OpenRAN ecosystem. Vodafone says it has championed the OpenRAN ecosystem since its conception in 2016 and is actively using OpenRAN across many parts of the UK.

    To celebrate the deployment of the site, the first 5G video call over OpenRAN infrastructure was made by Vodafone UK’s chief network officer Andrea Dona to the Minister for Digital Infrastructure Julia Lopez.

    Julia Lopez, Digital Infrastructure Minister, the Department of Digital, Culture, Media and Sport, said: “This phone call, the first in the UK to be made using 5G OpenRAN infrastructure, marks a big step forward for innovation in UK telecoms.

    {loadposition chris08}

    “OpenRAN will have an important role to play in the future of our mobile networks and I congratulate Vodafone for being the first to make it happen.

    “The government is investing in the technology through our £250 million diversification strategy so we can deliver the amazing benefits of 5G for people and businesses with more diverse, resilient and secure equipment in our networks.”

    Vodafone says the installation of equipment at the site marks a number of firsts, including:

    • The beginning of the first scaled OpenRAN project in Europe, with 2,500 sites committed by 2027
    • The first 5G OpenRAN site
    • The first time OpenRAN technology has been deployed on a UK macro site to carry live customer traffic

    Andrea Dona said, “This is the beginning of a new chapter for the mobile industry. Our team has been working tirelessly to take OpenRAN technology from a theory in our lab to our customers in the real world – it’s remarkable how much has been achieved in such a short period of time.

    “OpenRAN as a concept is only five years old, and we’re already fundamentally changing how we deploy connectivity infrastructure. This is a watershed moment in the telecoms industry, and a catalyst for change and evolution.”

    OpenRAN technology separates software from hardware, so there’s more flexibility for mobile operators. Where previously one vendor would have delivered the whole solution, OpenRAN enables telecoms operators to work with more specialist suppliers. Not only will this diversify the telecoms supply chain, adding resilience to Critical National Infrastructure, it will also act as a catalyst for innovation.

    This could result in more energy-efficient telecoms equipment, as well as increasing the speed at which mobile operators can deploy next generation networks. The technology is widely seen as a disruptor for the telecommunications industry.

    Vodafone added that as part of the first site installation, the following OpenRAN-compliant technology will be deployed:

    • Samsung virtualised Radio Access Network (vRAN) Solutions, as well as technical, product and integration support
    • Dell open hardware servers
    • Intel technologies to enable optimised solutions, including Intel Xeon processors, workload acceleration and connectivity
    • Wind River Studio for management of containerised OpenRAN CU/DU workloads, automation, orchestration, and lifecycle management of network functions

    Capgemini Engineering and Keysight Technologies provided testing and integration services in the Vodafone lab to ensure interoperability of the multi-vendor ecosystem. Once technologies and vendors have been verified as OpenRAN-compliant, deployment of equipment becomes a much simpler task, Vodafone added.

    OpenRAN 4G and 5G antennas from Samsung and NEC will be deployed from mid-2022. Once interoperability tests for these radio units have been completed in the lab, the units can be deployed in a ‘plug and play’ manner on the existing OpenRAN infrastructure.

    Samsung Electronics head of networks Europe Thomas Riedelat said: “As a global leader, we are proud to begin the UK’s first wide-scale OpenRAN commercial deployment, delivering carrier-grade 5G vRAN solutions to Vodafone. Based on our vRAN experience with tier-1 operators around the globe, this is another meaningful milestone for us, and we look forward to continue working with Vodafone.”

  • Airbus, NTT, NTT Docomo, and Sky Perfect JSAT studying high-altitude platform connectivity services to improve coverage

    Airbus, Nippon Telegraph and Telephone, NTT Docomo, and Sky Perfect JSAT are studying the feasibility of high-altitude platform stations (HAPS)-based connectivity services as part of a future space-based wireless connectivity ecosystem.

    The study will investigate how the unmanned aerial system Airbus Zephyr and wireless communication networks NTT, NTT Docomo, and Sky Perfect JSAT will work in order to test HAPS connectivity, identify practical applications, develop required technologies, and launch space-based wireless services.

    In the global push to further advance 5G and eventually introduce 6G, initiatives are under way to expand coverage worldwide, including in the oceans and in the air.

    Such initiatives will include HAPS, which fly in the stratosphere about 20km above the earth, and non-terrestrial network (NTN) technologies using geostationary-orbit (GEO) satellites and low Earth-orbit (LEO) satellites.

    {loadposition kenn}

    NTT claims HAPS networks are an easy solution for air and sea connectivity and an effective platform for deploying disaster countermeasures and many industrial applications. The provision of space-based radio access network services using NTN technologies, collectively called Space RAN (radio access network), is expected to support coverage and improved disaster resistance as well as enhanced 5G and 6G.

    In addition, HAPS platforms can also interconnect to the nearest terrestrial network gateway and extend the reach of existing mobile services directly to end-user devices, providing service options such as rural, emergency and maritime connectivity.

    The four companies will discuss and identify possible future developments to unlock future HAPS-based connectivity services, lobby for standardisation and institutionalisation of HAPS operations, and explore business models for commercialising HAPS services.

    The study will tackle the applicability of HAPS for mobile connectivity on the ground and base station backhaul, the performance frequency bands in HAPS systems, the considerations for linking HAPS with satellites and ground base stations, and establishing a system to test a network combining NTN technology, satellite, and HAPS.

    This collaboration comes on the heels of a propagation test conducted by Docomo and Airbus to examine the ground and the Zephyr S HAPS aircraft in the stratosphere last 15 November 2021, demonstrating the possibility of providing stable communication with such a configuration.

  • How 5G will revolutionise the transport and logistics industry in Australia

    During the COVID-19 pandemic, the Australian transport and logistics sector was tested in ways no one could have anticipated as the associated protection measures were introduced.

    Much like telecommunications, where connectivity became a lifeline, so too did the transport and logistics industry find itself at the heart of a core human need as the prevention of mobility meant that access to products (staples through to luxury) were restricted.

    Again, similar to telecommunications, this has led to elevated consumer expectations of the transport and logistics industry when we consider meeting shorter timeframes, more specific forecasting, and greater transparency around the status of goods being transported.

    Australia’s telecommunications infrastructure was crucial to meeting this need, but its success has set a new bar for consumer expectation which the transport and logistics industry will need to not only meet but exceed.

    The Australian Mobile Telecommunications Association (AMTA) has identified five ways that the reduced lag time, faster speeds and increased capacity of the 5G network will unlock significant opportunities for the transport and logistics industry. 5G will enable the industry to be more efficient and sustainable, and ensure it is well placed to tap into this potential with new innovations and technology that will enhance consumer experience while paving the way for a more connected future.

    1. Automated Vehicles

    Supported by 5G’s unparalleled low lag time, automated vehicles including cars, trucks, trains and drones will make freight and passenger transport safer and more efficient. 5G will also improve the reliability of last-kilometre travel – the last leg of a product or passenger’s journey – and so-called ‘vehicle-to-everything communication’, including communication between vehicles and the traffic system, across both commercial and public systems.

    In Australia, Qube is already installing 5G communications to link automated cargo vehicles at Moorebank Logistics Park (MLP) to the fleet management and safety system, with the low latency and high reliability of 5G used to create safe and reliable operations.

    HMI Technologies Australia is also trialing 5G technology to help operate Automated Shuttle Vehicles (ASVs) to provide enhanced mobility for disabled and elderly passengers for first and last-kilometre travel – the missing link in current public transport ecosystems.

    2. VR and AR Support

    5G’s greater speed and high capacity will improve the integration of Virtual Reality (VR) and Augmented Reality (AR) applications across transport and logistics businesses.

    5G-powered VR and AR will be used to train employees, providing immersive and ultra-realistic experiences without impacting day-to-day operations. Through 5G, AR applications like ‘vision picking’ – which involves displaying order information to warehouse staff through head-mounted displays – will be enhanced.

    Machine and vehicle maintenance will also become more efficient, with offsite technicians able to assist workers using AR headsets to monitor in first person and real time the status of their fleet. Through the instant connectivity and low latency that 5G brings to VR and AR, the transport and logistics industry will become more efficient and productive, while supply chains will become more efficient as transport and logistics interact more seamlessly and with less need for hands-on trafficking of data.

    There are already advanced types of AR and VR technology in development, like Microsoft’s Mesh, which could be harnessed by the industry in the future. However, while highly advanced AR and VR enabled technologies exist now, in a 5G-enabled world they will become much more mainstream as the availability of network connections makes these technologies more accessible and directly utilitarian.

    3. Connected Robots

    Leveraging 5G’s fast connectivity, increased capacity and more reliable broadband, connected robots and collaborative robots - or ‘cobots’ - will significantly change the way tasks are carried out across the supply chain. They will help workers with warehousing operations and enhance safety by reducing the need for people to physically carry out injury-risking or challenging tasks, like repetitive lifting.

    UTS and Nokia Australia have been working together to explore ways in which 5G and Edge Computing technology can be harnessed to make robots better co-workers. The ‘5G Connected Cobot’ project aims to build the next generation of robots that will be able to better navigate a changing environment and interact with people.

    Ericsson has also recently looked to 5G to trial extending the range of Boston Dynamics’ four-legged mobile robot ‘Spot’, to allow it to patrol the perimeter of Hans Christian Andersen Airport in Denmark, showcasing the opportunity for autonomous robots.

    4. Smart Factories and Warehouses

    The COVID-19 pandemic has highlighted the value to be gained through greater automation in smart factories and warehouses. 5G’s high capacity will enable multiple assembly lines, machines and assets to connect through the Industrial Internet of Things (IIoT) so operations can be monitored and optimised.

    Using AI powered by 5G, workers will also be able to implement predictive planning, which will increase the efficiency of assembly lines and warehouse inventory management, including just-in-time (JIT) delivery, so companies can receive parts and goods as close as possible to when they are actually needed.

    In Germany, DHL has been trialling a system within their warehouses that uses IoT technologies connected through 5G to help them build an accurate, real-time map of activities so they can optimise operations. Ericsson has also established smart factories in Sweden, Estonia and China which use 5G and IIoT systems to connect nearly every asset in the factory to improve traceability of inventory, dispatch services and maintenance accordingly, and ultimately improve end-to-end efficiency.

    5. Goods Tracking

    Tracking technologies are not new with short-range technologies, including radio-frequency identification (RFID) and optical codes being used for years. However, the billions of connections that will be supported through 5G means 5G-connected trackers will make a difference in improving the tracking of the location and condition of goods in real-time throughout every aspect of a supply chain, making delivery more efficient and resilient.

    This will allow transport and logistics companies to provide accurate real-time updates on delivery progress at any time, not just at a few key checkpoints, and also mitigate problems like delivery delays or cold storage faults.

    In Australia, Peloris Global Sourcing is already using IoT technology to monitor the location and temperature of milk being exported to China to ensure compliance and rapid border clearance and through 5G this technology could become more readily used across the entire industry.

    With the continued rollout of 5G across the country and the world, the transport and logistics industry will rapidly change over the next decade. It will not only become more efficient and reliable, but it also has the opportunity to become more profitable, with less human error, mismanagement and inefficiencies.

    A short video showcasing the 5 ways that 5G will change transport and logistics is available here.
