What role will 5G play in the gigabit broadband vision of NBN?



The Australian National Broadband Network (NBN) has been a controversial venture since its inception.

Originally conceived as a full-fiber-to-premise network (FTTP) that covers the vast majority of the country, with Fixed Wireless Access (FWA) and satellite technologies that fill in the gaps, the project has been with significant delays and Budget problems.

Long before BT committed itself to a "fiber-first" strategy, the company gladly used NBN as an example of what can go wrong with a full FTTP deployment and why Fiber to the Cabinet (FTTC) is the most cost-effective and fastest rollout method for super fast broadband was.

Full Fiber Challenges

The Challenges of an Ambitious Fiber Infrastructure A country as large and composed of as many different regions as Australia has finally been recognized, and NBN has since adopted a "mixed technology" approach ,

This means fiber for distribution on point (FTTdp), which Coper uses for part of the connection, can be used. Meanwhile, the speed targets have been made easier to support the rollout.

"Our penetration target is 1

00% from Australia, and we are committed to [by government]," says Ray Owen, CTO of NBN, to the Broadband World Forum (BBWF) in Berlin. "By 2020, we need to bring every Australian 25Mbps and 50Mbps to 90 percent."

So far, NBN has exceeded 63 percent of that target, and 4.5 million sites are connected to the network through wholesale partners such as Telstra and Vodafone connected. More than half of the customers use a package at a speed of 50 Mbps or faster, and data usage has increased seven-and-a-half times since 2012.

Mixed Technology Approach

At that time, the average monthly total was now 27.8 GB, now 206.88 GB. On a single day, the NBN 28 carries PB traffic.

The vast majority of NBN customers are connected to the node (FTTN) via FTTP or fiber. FTTN describes any connection method that uses copper for part of the connection while using FTTC in the UK, Owen explains that NBN tends to use fiber at the distribution point (FTTdp).

FWA customers connected via 4G technology have similar usage patterns as landline users. However, satellite companies consume significantly less data due to technology limitations

"Our satellite service has a fair usage policy of over 300 Gbps," says Owen. "We have two satellites, and we have to manage capacity, but it's the only [fair use policy] we have."

Enabling a Gigabit NBN

The primary priority for NBN is to meet its coverage requirements, but Owen is paying attention to what he needs to do when this goal is achieved.

"What do we do if we all have connected?" He asks. "That's why we have a technology path."

In particular, NBN intends to enable Gigabit broadband by introducing more fiber into the network and using G.Fast to accelerate copper links. The aforementioned problems with satellites mean that it is most useful in really remote areas with no alternative. What role can 5G play in facilitating this vision?

Is 5G a threat to NBN?

However, some in Australia have suggested this, NBN actively ignores 5G, as commercial networks of mobile operators pose a challenge to NBN's business model.

Broadband service providers complain that low margins on NBN-powered services are an attractive option for promoting 5G-FWA ISPs are already offering converged modems that can access both fixed and mobile networks.

There are allegations that NBN does not take this threat seriously, with just a single mention of 5G in its 192-page annual report, while the Australian Competition and Consumer Commission (ACCC) said it will not become NBN protect against the competition.

"We have an interesting development in Australia between the mobile networks and the NBN. said Rod Sims, chairman of the ACCC. "We're seeing a few vendors offering consumers hybrid modems with their NBN connection, where traffic can be routed over the cellular network instead of the NBN.

"This is just a small step towards operators who prefer their own mobile networks over the NBN, but do we see that it continues? However, what we should never do is to endeavor to hinder others in order to protect the NBN business model. This would be a disaster for consumers.

However, it is believed that heavy users will always rely on a solid connection. However, analysts and regulators believe mobile operators in the lower end of the market could be profitable with a 5G system Home-grown broadband service.

5G focus

NBN has dismissed the 5G threat, claiming it is paramount to complete the NBN network by 2020 and to defend 4G service competition.

"NBN Co broadband broadband broadband broadband is already competing, reaching speeds of up to 1 Gbps in some areas," explains NBN spokesman Tony Brown TechRadar Pro , "Despite this competition from 4G high-speed mobile devices, NBN is already achieving a nationwide target of almost 75 percent.

"We have always predicted that about 2 percent of homes will either be mobile. Only broadband connections are free or unmanned and do not require fixed broadband service – and that's exactly what happens on the ground.

"We see no significant reason to change our current position, and we are still on the way to activate 8 million. The network is located in the NBN network until 2020. The reality is that landline broadband networks – including the 4.4 million households and NBN network companies – still account for around 97 percent of all Internet traffic, even with high-speed 4G services available nationwide. Australia carries the rest with mobile phones.

"The NBN network will provide Australian households and businesses a great landline connection that can deliver both high speeds and large volumes of data, while 5G will deliver high-speed, outdoor mobile connectivity. "

At the moment, the NBN's interest in 5G seems to be limited to how it can improve its FWA service once it reaches that 2020 goal.
