Telstra has begun internal testing of millimetre wave 5G, and is planning to provide some customers with trial access.

Being at the forefront of 5G is a strategic issue for Telstra, chief executive Andy Penn said this morning.

The company is working with Ericsson, Qualcomm and other partners on a trial of mmWave 5G.

The basic strategy is to launch early, get customers on the network, and learn from their experience. Telstra already has more than 100,000 5G customers, with coverage in around 430 suburbs in 32 towns and cities. This should increase to 35 cities by mod-2020.

Some four million people live in or pass through Telstra's 5G coverage areas, Penn said.

Telstra had more than 800 5G sites at the end of 2019, and is "pushing ahead rapidly" with the rollout, as well as upgrading its 4G network to deliver improved speeds.

5G launched here using mid-band frequencies (Telstra uses 3.6GHz). mmWave operates in the high band (26GHz in Australia), which allows greater speed but the signal doesn't propagate as far.

5G devices will evolve to use multiple bands, optimising the balance of range and bandwidth.

Telstra's mmWave trial is possible as it has obtained so-called scientific licences for 26GHz spectrum from the Australian Communications and Media Authority, ahead of the spectrum auction expected in the first quarter of 2021.

Trial locations have yet to be announced, but Telstra 5G network principal Paul Milford did mention that one of them is the Melbourne Cricket Ground. The high capacity but short range nature of mmWave makes it particularly suitable for high density areas such as stadiums.

The trials will explore a variety of use cases. Telstra's 5G core system allows for network slicing, which mean the telco can offer quality of service levels to support different customer requirements. For example, serious gamers may be prepared to pay for a low latency, low jitter connection. Low latency is also important for robotics, he said.

"5G is not going to replace the NBN," Penn emphasised. The average fixed-line user consumes around 30 times as much data as a wireless user. Some customers will find 5G is appropriate for them, he said, noting that Telstra has stopped selling 100Mbps NBN plans to premises serviced by VDSL (FTTN, FTTC) technology, because there is no way to determine what speed can actually be delivered before the service is installed, causing "too much pain for the customer."

It is "appropriate for us to provide the best technology" as it develops, he said.

"[First generation 5G] handset prices are very high" at around $2000, Penn conceded. But the second generation are on their way, and some will be around the $1000 mark, even at current exchange rates, he predicted.

Joining Penn at the media briefing, Ericsson Australia and New Zealand head Emilio Romeo said: "Ericsson is very proud to be a long term partner of Telstra," adding that the relationship extends more than a century.

Telstra's mobile network is one of the best in the world, and overseas visitors are "astounded" by its quality, he sad.

“This announcement is an important step in realising the benefits of mmWave spectrum for Australia and the world. With 5G live demonstrations on the 26GHz band now underway, this is a significant step in showcasing how mmWave can be scaled and integrated into a commercial mobile network," said Romeo.

“Ericsson is pleased to be working with Telstra and Qualcomm Technologies to drive industry leadership through ongoing innovation and collaboration, and importantly helping Telstra to ensure Australians are among the first customers in the world to experience this technology.”

The trial will use the Telstra 5G Wi-Fi Pro wireless router, said to be Australia's first mmWave device. It incorporates Qualcomm's Snapdragon X55 5G modem-RF system. “This collaboration and milestone is an important step towards accelerating deployment of 5G NR mmWave technology in Australia and across the globe," said Qualcomm Technologies senior vice president and general manager of 4G/5G Durga Malladi.

  • NBN Co, telcos get ACCC authorisation to co-operate during COVID-19 crisis

    National Broadband Network operator NBN Co and five retail service providers have been authorised by the competition regulator the ACCC to work together on measures to keep telecommunications networks operating effectively during the COVID-19 crisis.

    Under the interim authorisation a special working group formed by NBN Co and the RSPs will share information, coordinate strategies to manage congestion and take other steps to address significant demand changes caused by the COVID-19 pandemic and the large numbers of people now at home during the day.

    The Australian Competition and Consumer Commission (ACCC) - which will be an observer on the special working group - says authorisation allows the NBN Co and the RSPs to support consumers and small businesses adversely impacted by the pandemic.

    The coordinated effort by NBN Co and Australia’s five biggest telcos - Telstra, Optus, Vodafone Hutchison, TPG and Vocus - comes at the request of the Minister for Communications, Cyber Safety and the Arts, Paul Fletcher.

    The ACCC says the five RSPs and NBN Co have also sought urgent authorisation to provide support for consumers and small business customers experiencing financial difficulties as a result of COVID-19, “with the ultimate aim to ensure that consumers are able to stay connected to communications services throughout the pandemic”.

    “Online services and connections are now more important than ever, as Australians seek to stay productive and engaged, undertake home schooling, telehealth and access other services. The ability to do all this will also assist people to comply with increasingly strict social distancing measures,” ACCC Chair Rod Sims said.

    “As it has with a number of industries already, the ACCC stands ready to assist telecommunications providers with approval of any coordinated measures that are urgent and necessary during this crisis.”

    Some Australian retail service providers are not members of the special working group and, as a condition of the authorisation, the ACCC says NBN Co must quickly inform it - and non-member service providers - about any material decisions made by the group that might affect them.

    NBN Co says it welcomes the ACCC announcement authorising the telecommunications industry's "cooperative and collaborative approach" to help support Australian residential and business customers during the ongoing COVID-19 pandemic.

    "We are pleased that the ACCC has moved swiftly to grant the necessary permission that allows NBN Co to continue to lead and co-ordinate the whole-of-industry response within the telecommunications and communications sector, and we recognise and appreciate the resolve and commitment of our industry partners during this time," NBN Co said in a statement released on Wednesday.

  • ManageEngine offers free tools for remote working

    Organisations that had not already adopted flexible working face particular IT issues during the COVID-19 pandemic.

    For some jobs, taking a laptop home and connecting it to the internet is pretty much all that's required. But for others, access to specific systems is important.

    ManageEngine, the IT management division of Zoho, has more than 8000 employees in 10 countries. It was able to make an early decision to ask them to work from home by eating its own dogfood.

    ManageEngine's tools such as Access Manager Plus and Remote Access Plus allow seamless yet secure connections to desktops, servers, databases, and network devices from employees' homes.

    {loadposition stephen08}

    Remote Access Plus does what its name suggests – it provides remote access to systems. This could be useful where someone's job requires the use of specialised software, especially applications such as CAD which have particularly demanding hardware requirements. Another use is to provide technical support to employees working at home on company-managed computers.

    Remote Access Plus requires the installation of a lightweight agent on the system to be controlled, which can be running Windows, Linux or macOS. At the remote end, any modern browser that supports HTML5 can be used.

    Remote Access Plus

    Access Manager Plus addresses the problem of remotely managing infrastructure such as servers and databases. Privileged sessions for maintenance and troubleshooting are typically restricted to the data centre, ManageEngine vice president Rajesh Ganesan observed.

    Installed in the data centre, Access Manager Plus provides secure channels so such tasks can be carried out remotely. Unlike VPNs, it provides granular access controls, restricting users to the operations, files and folders their job requires. It can also prevent files being copied to the remote system, and to enforce session time limits. All activities are logged for analysis, and the software can be connected to SIEM tools.

    Access Manager Plus

    As with Remote Access Plus, all an Access Manager Plus user needs is a browser.

    Fully-functional versions of both these tools are available free of charge until 1 July, and Ganesan told iTWire that the offer may be extended if the situation hasn't improved by then.

    "Remote access is extremely critical" to business continuity, but it must be done securely, he said.

    Within a week of the offer commencing, and before any real attempt to publicise it had been made, some 600 companies were already taking advantage of the temporarily free software.

  • Huawei faces more tough times ahead in Australia

    ANALYSIS In August 2018, Huawei was told that it was not going to be able to bid for something which could prove to be its biggest source of revenue in Australia: 5G contracts.

    And a few days back, the company had to pull out of its existing biggest contract in this country: a $136 million deal with WA to build and maintain digital radio services that would provide voice and data services across the rail network in Perth.

    At the beginning of March, Huawei went through a restructure, getting rid of its board and also axing 500 jobs. On Wednesday, the company put out an announcement reiterating its commitment to sponsorship of the NRL team, the Canberra Raiders.

    Ostensibly, this was intended to reassure the Raiders at a time when the NRL season is in limbo due to the ongoing coronavirus pandemic. But it was also a reassurance to its commercial clients that it is not planning to cut and run despite the major setbacks it has faced.

    {loadposition sam08}A re-evaluation of its position will probably have to be made at the point when 5G networks are adopted in toto by the likes of Optus and Vodafone Hutchison Australia; both companies built their 4G offerings on Huawei's infrastructure but will have to shift to other companies for 5G. Optus has said it would mainly use Swedish provider Ericsson while Vodafone has opted for Nokia.

    This process will take at least another five years to be completed, so there is a reason for Huawei to keep the carrier side of its operations going at least until then. But as the amount of work gradually reduces, there are likely to be staff cuts in this area.

    Newer Huawei smartphones are unlikely to be bought by Australians in large numbers given that the proprietary Google apps — Gmail, YouTube, Maps, Drive and the Play Store — are absent, due to an American ban. That means the consumer side of the business will not see much revenue.

    If Google were to gain an exemption from the ban allowing it to sell the proprietary Android apps to Huawei, then the prospects of the Chinese firm's smartphones gaining market share would be good. The hardware is said to be good, with the camera outstanding.

    But this is a third-party opinion; iTWire has repeatedly attempted to obtain a recent smartphone from Huawei for review, but has not been successful. Hence an opinion about other apps on the devices cannot be offered.

    The company has other ongoing contracts in Australia which need to be serviced. iTWire understands that Huawei Australia operates private networks for several mining operators. Additionally, there are clients like Sydney Trains, NSW Ambulance, Southern Cross University, James Cook University and the Gold Coast Suns.

    Nothing will happen tomorrow or the day after either. But it looks like a company which has had operations in Australia for the last 16 years will be reduced to a token presence before the next decade arrives.

  • MariaDB launches SkySQL DBaaS

    MariaDB says its new SkySQ is the first database-as-a-service (DBaaS) to unlock the full power of MariaDB Platform for transactions, analytics or both, optimised with a cloud-native architecture.

    The company claims SkySQL delivers the experience customers have been waiting for: fully featured, fully customisable and backed by support and expertise from the engineers who built it.

    "The universal need for accessible yet robust database services has never been higher - for around-the-clock critical operations and simplified analytics for a changing world," said MariaDB CEO Michael Howard.

    "Existing services, long in the tooth, lock out community innovation, meaning patches, new versions and features are missing for literally years. MariaDB SkySQL is a next-generation cloud database, built by the world's top database engineers in the industry, allowing organisations large and small to know they have an always-on partner to not only roll out new applications, but ensure a consistent and enduring quality of service."

    {loadposition stephen08}

    According to MariaDB, SkySQL is capable of supporting mission-critical workloads; is based on the latest version of the MariaDB platform; provides row, columnar, and combined row and columnar storage; and comes with the same support and peace of mind on-premises MariaDB customers currently enjoy.

    "A DBaaS direct from the source means customers get the added benefit of influencing feature decisions and revenue is reinvested back into MariaDB innovation," the company said.

    In addition, MariaDB offers cloud database administrator (DBA) support for the SkySQL DBaaS.

    "Our initial testing showed better than expected performance with SkySQL on Google Cloud Platform," said Telefónica UK head of engineering for O2 Enterprise and Wi-Fi Paul Greaves.

    "MariaDB SkySQL will open up new opportunities for us to iterate faster and provide a better experience for our customers."

    SkySQL takes advantage of Kubernetes for container orchestration; ServiceNow for inventory, configuration and workflow management; and Prometheus and Grafana for real-time monitoring and visualisation.

    It is designed for multi-cloud and hybrid cloud deployments, so customers aren't locked into one public cloud vendor's ecosystem. However, SkySQL is initially available on Google Cloud Platform, with prices starting at US$0.45 per hour.

  • Amazon Detective goes GA

    Amazon Web Services' new Amazon Detective security service is now generally available.

    Amazon Detectiveannounced last December – is designed to make it easier for customers to conduct faster and more efficient investigations into security issues across their AWS workloads.

    It applies machine learning, statistical analysis, and graph theory to log data, building interactive visualisations to help customers analyse, investigate, and identify the root causes of potential security issues or suspicious activities.

    Once enabled, Amazon Detective automatically begins distilling and organizing data from AWS CloudTrail, Amazon VPC Flow Logs, and Amazon GuardDuty findings into a graph model, and produces tailored visualisations to help customers answer questions like "is this an unusual API call?" or "is this spike in traffic from this instance expected?" without having to organise any data or develop, configure, or tune their own queries and algorithms.

    {loadposition stephen08}

    Amazon Detective's visualisations help analysts quickly determine the nature and extent of issues identified by AWS security services.

    Its graph model and analytics are continuously updated as new data becomes available, allowing security teams concentrate on remediation rather than data wrangling.

    "Even when customers tell us their security teams have the tools and information to confidently detect and remediate issues, they often say they need help when it comes to understanding what caused the issues in the first place," said AWS vice president for security services Dan Plastina.

    "Gathering the information necessary to conduct effective security investigations has traditionally been a burdensome process, which can put crucial in-depth analysis out of reach for smaller organisations and strain resources for larger teams. Amazon Detective takes all of that extra work off of the customer's plate, allowing them to focus on finding the root cause of an issue and ensuring it doesn't happen again."

    WarnerMedia public cloud security leader Chris Farris (who also teaches cloud security for the SANS Institute) said "Large security organisations are tasked with protecting huge environments with diverse workloads from a multitude of threats, while the smaller organisations I talk to often don't have the resources to replicate the tooling and expertise of their bigger counterparts.

    "Amazon Detective will help both of these groups reach faster, better-informed conclusions to their security investigations. It does the hard work of aggregating and analysing high-volume telemetry sources like VPC Flow logs and CloudTrail. Larger organisations will see major efficiencies, and small teams will have access to information and tooling that they'd have a hard time collecting and building on their own."

    Amazon Detective is available today in various AWS regions including Asia Pacific (Sydney) and Asia Pacific (Singapore).

    The only additional charge for using Amazon Detective is for data ingestion from AWS CloudTrail, Amazon Virtual Private Cloud (VPC) Flow Logs, and Amazon GuardDuty findings.
