NBN Co has spent the past week performing capacity upgrades for almost 200 fixed wireless towers in six states and territories.

The sizable portion of upgrades began on July 24 with most work expected to wrap up today, barring any extensions to maintenance windows.

The largest proportion of work focused on towers in Victoria (89) followed by NSW (66), based on analysis by iTnews.

NBN Co said in advisories sighted by iTnews that the “upgrade work is expected to improve the overall performance of the fixed wireless network in the areas”.

“However, not all users will necessarily notice an improvement to their service,” the network builder said.

“For example, this upgrade may be intended to improve other services in the area or may be one of several related upgrades planned for the area.”

An NBN Co spokesperson told iTnews the chunk of upgrades were part of the extra $800 million announced in last year’s corporate plan to remediate the fixed wireless network.

“In 2018 we committed an additional $800 million investment to improve the customer experience on the fixed wireless network,” the spokesperson said.

“Our upgrades have begun to show signs of improvement and we will keep working to further improve the fixed wireless network in the coming months and into the future, as we continue with our planned upgrade activity.”

NBN Co’s fixed wireless woes are the combination of legacy network provisioning decisions and issues that were not previously captured in internal reporting of congestion levels.

The Australian Competition and Consumer Commission has previously raised the prospect of forcing NBN Co to pay rebates to users stuck in congested cells; unsurprisingly, the network builder is against the idea.

It is understood that retail service providers (RSPs) are given weekly updates by NBN Co on planned wireless infrastructure upgrades.
