Huawei Australia announced it had been awarded the contract to build and maintain the digital radio systems to deliver voice and data services across Perth's rail network.
Huawei will deliver the $136m project on behalf of the Public Transport Authority (PTA) as part of a joint venture with UGL.
The project commences later this month and is due for completion in 2021.
The Radio Systems Replacement project will deliver a total end-to-end digital radio solution across the PTA's 180km electrified rail network and the new Forrestfield Airport Link twin tunnels.
The Huawei UGL joint venture will design, install and commission the service and maintain the new digital radio system for an initial period of five years from completion with options for a further five plus five years.
Huawei Australia Chairman, Mr John Lord said the PTA contract reinforced Huawei's strong long-term investment focus in the Australian market and was a validation of the company's status and reputation as the global cellular wireless leader.
Lord says, "Huawei is extending its trusted portfolio of solutions towards industry and strengthening its customer base in mission-critical market segments.
"We are modernising the Australian transportation sector through digital technologies developed for the global market.
"We have been providing similar communications technology services to Sydney Trains and Ambulance NSW safely and securely for nearly a decade.
"We thank the PTA for the trust they have placed in Huawei and their support for WA local businesses, as we work closely together over the coming years to realise this substantial project.
As part of the contract, local WA steel and labour will be applied for fabricating, assembling and testing outdoor cabinets and towers.
More than 50 WA-based staff, including local subcontractors, will be employed during the forty-month design and build period.
The new systems will operate over a 3GPP Long Term Evolution (LTE) network using the PTA's existing 1800MHz spectrum.
