Optus runs mmWave 5G tests in Sydney – Telco/ISP- Tempemail – Blog – 10 minute

Optus is testing 5G millimetre wave (mmWave) technology at four locations in Sydney, months after suggesting the technology could bring speeds in excess of 20Gbps.
The telco said in a statement that it has Australian Communications and Media Authority (ACMA) approval to operate and test mmWave technology using the 26GHz band “at four locations in Sydney, including its Macquarie Park headquarters”.
As part of its tests, the company made a data call with technology partner Ericsson using mmWave customer premises equipment (CPE) made by Casa Systems.
It has also “run extensive testing at its lab facility in Sydney,” it said.
The telco reinforced its interest in using mmWave to serve the enterprise market in the first instance.
“MmWave 5G is the next step in unlocking mass productivity gains through a high-speed wireless communication layer,” Optus Networks managing director Lambo Kanagaratnam said.
“The enterprise market in particular is expected to gain from mmWave, with sectors such as autonomous manufacturing, mining and port operations all examples of industries that will considerably benefit from mmWave 5G and its capability to offer higher speeds.”
A mmWave spectrum auction is currently scheduled for early next year.

NBN Co starts testing feasibility of mmWave for future fixed wireless – Telco/ISP- Tempemail – Blog – 10 minute

NBN Co has commenced feasibility trials for the delivery of broadband services in millimetre-wave spectrum, which it sees as a potential long-term upgrade path for its current fixed wireless footprint.
The company said in a heavily-redacted regulatory filing [pdf] that it is “undertaking trials to validate the feasibility of using the 26GHz and 28GHz band spectrum over very long ranges (approximately 10km)” for the delivery of fixed wireless broadband services.
“Our studies, and those of our technology partners provide high levels of confidence that the long-range use would allow NBN Co to have significant flexibility to maximise our deployment and upgrade options,” it said.
“This long-range approach is enabled by our unique network topology with 100 percent external CPEs [customer premises equipment], and largely line of sight deployment in regional and rural areas.”
NBN Co first flagged millimetre-wave (mmWave) – a type of 5G – as an upgrade path for fixed wireless back in mid-2018.
It started laying the groundwork to be allocated enough mm-Wave spectrum at the end of 2018.
The public-facing documentation does not reveal how far into feasibility trials NBN Co is, though much of the detail is redacted.
NBN Co argued that “any allocation” of mmWave spectrum to it would improve services for customers and “facilitate competition between all NBN Co’s fixed wireless retail service providers in downstream markets”.
It said there are currently “more than 20” retail service providers in the market competing for NBN fixed wireless users.
“Competition will be enhanced and driven where we provide a quality fixed wireless network that efficiently uses spectrum and is upgradable where required,” NBN Co said.
“We anticipate that the outcome of our long-range trials will verify that NBN Co is able to utilise the acquired spectrum in an economically efficient manner.”

ACMA to set EME standards for mmWave 5G devices – Telco/ISP- Tempemail – Blog – 10 minute

The Australian Communications and Media Authority is looking at how it can regulate electromagnetic energy (EME) exposure from 5G devices operating in millimetre-wave (mmWave) frequencies.
In a brief paper released late Wednesday, the ACMA noted there are “no finalised international standards on assessment methods for devices operating above 6GHz that are used in close proximity to the head or body.”
Mmwave spectrum is set to be used to supply high-capacity internet services in concentrated areas.
“Currently, the EME of devices operating above 6GHz that are used in close proximity to the head or body is regulated through licence conditions and is the responsibility of the licensee,” the ACMA said.
The ACMA currently oversees a standard called ‘electromagnetic radiation – human exposure’ that covers emissions from transmitters.
“The objective of the arrangements is to ensure that public exposure to EME from radio transmitters does not exceed the Australian exposure limits published by the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA),” it said.
The ACMA is hoping to extend this existing standard to cover mmWave 5G devices, and to use a technical report prepared by the International Electrotechnical Commission (IEC) as the basis of its thinking.
“Adopting [the technical report] into the ACMA standard will give manufacturers and importers clear guidance on measurement methodologies for assessing their device against the ARPANSA limits, and place EME obligations on the Australian supplier of the devices,” the ACMA said.
“Adopting a technical report is a departure from the ACMA’s normal approach of adopting international standards once they have been finalised.
“In this case, the speed with which technological development is occurring means that devices operating in close proximity to the ear or body above 6GHz may be available in Australia before the international standard is finalised. 
“Adopting the technical report is proposed as an interim measure until the international standard is available.”
The ACMA is accepting submissions from industry on the proposal up until March 12.
