U.S.-led efforts to banish Chinese technology vendor Huawei have been unsuccessful, according to figures released in a new report by research company Dell’Oro Group.

Huawei steep growth arc has been slowed by Western sanctions. But it continued to hold a market share lead in the global telecom equipment supply business in 2019, controlling 28% of the market—flat with 2018. And Huawei’s revenue continued to grow at a time when Western suppliers including Cisco, Nokia and Ericsson each saw slippage.

Notably, ZTE—another Chinese company that, while less so than Huawei, has also been accused by the Trump Administration for helping the Chinese government conduct espionage—saw its market share rebound by 2% in 2018.

“The efforts by the U.S. government to curb Huawei’s rise has so far had mixed results—we estimate Huawei’s overall telecom equipment share continued to improve in 2019, but the pace of the 2019 share growth was weaker than its average 2014-2019 share growth," Dell'Oro Group said in a note sent to journalists. 

The amount of money cable operators spend on broadband access equipment will decrease by 2% from 2019 to 2024, research company Dell’Oro Group predicts in its latest report.

Part of the cause, the firm said, is virtualization—operators will spend less on access hardware tech, as software virtualizes components like cable modem termination system (CMTS). In fact, Dell’Oro predicted revenue from virtual CMTS revenue will grow from $90 million last year to $418 million in 2024, but operators will spend less overall on equipment.

Meanwhile, Dell’Oro said that maturing broadband markets in the U.S. and Europe are also a factor, as is the pause operators are taking following wide-scale deployments of DOCSIS 3.1.

“Global operators continue to invest in their broadband access networks, but are increasingly delivering more capacity with lower-cost, virtualized hardware,” said Jeff Heynen, senior research director at Dell’Oro Group, in a statement. “Virtualization, coupled with subscriber saturation in some mature markets will result in gradually declining revenue for broadband access equipment globally.”
