China's Huawei Technologies said on Thursday its consumer business sales exceeded a record $52 billion in 2018, on strong demand for its premium smartphones, even as it continued to face heightened global scrutiny of its activities.

The jump of around 50 percent in the technology giant's consumer business revenue saw that unit replace its carrier business as its largest segment by sales, Richard Yu, the head of the consumer division, said in Beijing.

Huawei last month flagged that total revenue in 2018 rose 21 percent to $109 billion without providing a breakdown of segment performance.

Huawei on Thursday also unveiled its first 5G base station chipset called Tiangang as well as its 5G modem Balong 5000, which it described as the most powerful 5G modem in the world.

Yu said it was the world's first 5G modem that fully supports both Non-Standalone (NSA) and Standalone (SA) 5G network architecture.

The firm has been using its chipsets in its high-end phones and server products, though it has said it has no intention to become a standalone semiconductor vendor that competes against the likes of Intel and Qualcomm.
