Huawei announced that it would be leaving AMTA on 22 August, a year after Australia announced that it and its Chinese compatriot, ZTE Corporation, would not be allowed to participate in the rollout of 5G networks Down Under.
In a letter sent to AMTA chief executive Chris Althaus, Huawei Australia Corporate and Public Affairs director Jeremy Mitchell said the company was taking this step as it felt it had not been fairly represented by AMTA.
"AMTA's decision not to publicly highlight the real effects from the government's 5G decision on the Australian telecommunications landscape was extremely disappointing," he wrote.
Mitchell also pointed out that the technical advice given to the government on the split between core and non-core elements in 5G was at odds with the global 5G standards and the actual rollout of 5G globally.
"AMTA has an important voice to ensure that these policy decisions are based on facts and the correct technology design," Mitchell said. "Clearly, AMTA's decision to stay silent was in stark contrast to similar associations around the world."
Asked about the lack of any action to communicate with the government on the issue, an AMTA spokesperson told iTWire: "At no time has AMTA had any engagement with government in the decision-making processes related to Huawei's situation.
"AMTA will continue to work hard with members and on behalf of the mobile industry as a whole to promote the key role of mobile telecommunications in Australia's economy and society - including the transformational role of 5G in Australia's future."
"The Australian mobile sector can be proud of its leadership through the generations of mobile technology which will continue in the 5G era."
Mitchell added that it was likely the company would quit the AMTA Mobile Muster phone recycling program and look for another organisation with which to partner when its existing contract with AMTA ended.
