Europe would fall behind the US and China in the race to install the next generation of wireless networks if governments ban Chinese equipment supplier Huawei Technologies Co (華為) over security fears, an internal assessment by Deutsche Telekom AG said.
Officials at Europe’s largest telecom have said that removing Huawei from the list of 5G network suppliers would delay roll-out of the technology by at least two years, people familiar with a briefing paper said.
The people asked not to be identified because the findings are confidential, while a Bonn-based Deutsche Telekom spokesman declined to comment.
Germany and other European governments have been weighing whether to place restrictions on the use of Huawei equipment over concerns that Chinese intelligence could use it to spy on other countries, fears the company has dismissed.
The Deutsche Telekom paper shows how nervous the industry has become that governments could throw its carefully laid network expansion plans into chaos.
Huawei has become a leading supplier to European phone companies as they prepare to spend billions of euros on 5G to cope with surging data demand and support potentially lucrative applications such as self-driving cars, smart appliances and connected factories.
Deutsche Telekom has installed Huawei systems in thousands of its wireless towers. The supplier’s technology also forms the backbone of some of the company’s cloud products.
In its internal assessment, Deutsche Telekom said that 5G networks must be built on top of existing 4G infrastructure, which already relies extensively on Huawei gear, so if Huawei is banned outright and companies are forced to rip out all of its equipment, that would cost the industry many billions of euros.
Such a blanket, retroactive ban on using Huawei for 4G might be unlikely; bans elsewhere in Australia and New Zealand, for example, have prohibited purchases of Huawei gear solely for 5G networks, which are viewed as harder to police as they process much of their data outside a central core.
Some telecoms are already dialing back work with Huawei as the pressure on the company grows, throwing their cooperation into doubt.
Vodafone Group PLC last week said it is suspending some Huawei equipment purchases for the core of its networks in Europe.
Deutsche Telekom last month said it is re-evaluating its purchasing strategy — a first indication the German carrier might drop the Chinese company from its list of suppliers.
Dropping Huawei in Europe would not be easy — most carriers have ordered its equipment because the technology is often seen as superior to that of its rivals.
Competitors, including Ericsson AB, Nokia Oyj, Cisco Systems Inc and Samsung Electronics Co, would have to step in if Huawei were to be banned, potentially leading to capacity constraints.
POWERING UP: PSUs for AI servers made up about 50% of Delta’s total server PSU revenue during the first three quarters of last year, the company said Power supply and electronic components maker Delta Electronics Inc (台達電) reported record-high revenue of NT$161.61 billion (US$5.11 billion) for last quarter and said it remains positive about this quarter. Last quarter’s figure was up 7.6 percent from the previous quarter and 41.51 percent higher than a year earlier, and largely in line with Yuanta Securities Investment Consulting Co’s (元大投顧) forecast of NT$160 billion. Delta’s annual revenue last year rose 31.76 percent year-on-year to NT$554.89 billion, also a record high for the company. Its strong performance reflected continued demand for high-performance power solutions and advanced liquid-cooling products used in artificial intelligence (AI) data centers,
SIZE MATTERS: TSMC started phasing out 8-inch wafer production last year, while Samsung is more aggressively retiring 8-inch capacity, TrendForce said Chipmakers are expected to raise prices of 8-inch wafers by up to 20 percent this year on concern over supply constraints as major contract chipmakers Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) and Samsung Electronics Co gradually retire less advanced wafer capacity, TrendForce Corp (集邦科技) said yesterday. It is the first significant across-the-board price hike since a global semiconductor correction in 2023, the Taipei-based market researcher said in a report. Global 8-inch wafer capacity slid 0.3 percent year-on-year last year, although 8-inch wafer prices still hovered at relatively stable levels throughout the year, TrendForce said. The downward trend is expected to continue this year,
‘BASICALLY A BAN’: Sources said the wording governing H200 imports from officials was severe, but added that the regulations might change if the situation evolves Chinese customs authorities told customs agents this week that Nvidia Corp’s H200 artificial intelligence (AI) chips are not permitted to enter China, three people briefed on the matter said. Chinese government officials also summoned domestic technology companies to meetings on Tuesday, at which they were explicitly instructed not to purchase the chips unless necessary, two of the people and a third source said. “The wording from the officials is so severe that it is basically a ban for now, though this might change in the future should things evolve,” one of the people said. The H200, Nvidia’s second-most powerful AI chip, is one
A proposed billionaires’ tax in California has ignited a political uproar in Silicon Valley, with tech titans threatening to leave the state while California Governor Gavin Newsom of the Democratic Party maneuvers to defeat a levy that he fears would lead to an exodus of wealth. A technology mecca, California has more billionaires than any other US state — a few hundred, by some estimates. About half its personal income tax revenue, a financial backbone in the nearly US$350 billion budget, comes from the top 1 percent of earners. A large healthcare union is attempting to place a proposal before
