Company Overview

Singtel Optus Pty Limited is the second largest telecommunications company in Australia. It is a wholly owned subsidiary of SingTel (a company headquartered in Singapore) since 2001. The company primarily trades under the Optus brand, while maintaining several wholly owned subsidiary brands, such as Virgin Mobile Australia in the mobile telephony market, Uecomm in the network services market and Alphawest in the ICT services sector.

To provide services, Optus mostly owns and operates its own network infrastructure, and also uses the wholesale services of the National Broadband Network and Telstra. It provides services both directly to end users and also acts as a wholesaler to other service providers such as Exetel and Amaysim. Through its Optus 'Yes' brand, it provides broadband, and wireless internet services. Other wholesale services include Satellite and 4G Mobile, in fact Optus is the largest satellite wholesaler in Australia.

The company operates 3G services over B8 (900 MHz) with B1 (2100 MHz) deployed in many metropolitan areas to provide additional capacity. Optus has been rolling out its 4G LTE services over B3 (1800 MHz) since 2012, adding B7 (2600 MHz) and B28 (700 MHz) in 2014.

After acquiring Vivid Wireless in 2012 Optus secured 98 MHz of spectrum in the 2300 MHz band, which the company has since refarmed into B40 (2300 MHz) LTE. The acquisition also secured spectrum in the 3500 MHz band which it has successfully piloted B42 (3500 MHz) LTE on but remains largely unused. The company also has numerous activations of B1 (2100 MHz) and B8 (900 MHz) LTE.

Optus launched LTE-A Pro "4.5G" services in February 2017, boasting peak data rates in excess of 1 Gbps, using carrier aggregation, 256QAM modulation, and 4X4 MIMO technologies. This was extended further in September 2017 when the company deployed Massive MIMO in some areas of its live network, featuring 64T64R MIMO using technology supplied by Huawei.

In February 2017 the company also announced successful NB-IoT trials in partnership with Cisco Jasper.

Optus 5G

Optus announced its intention to launch 5G NR in early 2019 after tests demonstrated peak DL data rates in excess of 2 Gbps to residential-grade CPE over 3.5 GHz and mmWave bands. The company secured 30 to 35 MHz of 5G spectrum in the 3575 to 3700 MHz range in Australia's November 2018 auction, adding to its substantial 3.5 GHz spectrum holdings. In January 2019 Optus announced the successful pre-launch testing of a 60 MHz n78 (3500 MHz) 5G data service. Optus' 5G rollout schedule was announced in January 2019 detailing 50 live sites by March 2019, and 1200 sites to be completed by March 2020.

The company has expressed interest to the Australian Communications and Media Authority (ACMA) regarding licencing of the 26 GHz band for mmWave 5G services.

News & Developments

Optus today revealed the first details of its game changing 5G Home Broadband service which is underpinned by a plan to deliver 1,200 5G sites by March 2020.

In partnership with Nokia, who are supplying the 5G RAN and Fastmile 5G CPEs, Optus 5G sites are now live in two suburbs in Canberra, with an additional site live in Sydney and 47 more sites planned to be online by March 2019.

Optus has taken another significant step towards its commercial launch of 5G today by making a 5G data call on 60 MHz using 3.5 GHz spectrum.

The call, made as part of pre-launch testing, was made from an Optus 5G site in Dickson, Canberra utilising a commercial grade 5G Radio Network and customer premises equipment (CPE) developed in partnership with Nokia.

Four companies have won valuable 5G spectrum in the Australian Communications and Media Authority’s latest spectrum auction in the 3.6 GHz band.

Optus has launched Optus 5G Live in Broadbeach, and in a world first, will simultaneously showcase 5G use cases and 8K video streaming on-the-go, on its live 5G trial indoor and outdoor network.

The showcase offers a preview of the state-of-the-art technology and marks a significant milestone in Optus’ commitment to make leading 5G technological advancements.

Optus has announced its intention to commence the roll out of 5G technology in Australia by early 2019 with a fixed wireless product in key metro areas.

Optus has announced the successful live network testing of combined Massive MIMO (Multiple Input Multiple Output) and 3CC Carrier Aggregation technologies, 3CC Massive MIMO.

The network trial, conducted on live traffic at Macquarie Park in June 2017, attained a highest speed of 818 Mbps. It was completed with technology partner Huawei.

Optus is spending $1 billion building 500 new mobile base stations around regional Australia to compete better against Telstra and Vodafone. 

Cisco Jasper is seeing increasing support for NB-IoT throughout its global service provider partnerships and demand from enterprises worldwide. The company has already completed live trials, including initial core network trials with Optus in Australia, which has completed integration of the Cisco Jasper platform to support NB-IoT.

Optus has signed a memorandum of understanding (MoU) with Nokia to collaborate on the network evolution to 5G, which will enable a host of network capabilities such as massive Internet of Things, extreme broadband and ultra-low latency applications.
