An environmental group protested outside the WiMAX Expo over the potential health impact of electromagnetic radiation as President Ma Ying-jeou (馬英九) visited the trade show at the Taipei World Trade Center.
Ma, who took pride in his efforts to boost wireless Internet service in Taipei during his two terms as mayor, pledged to use Worldwide Interoperability for Microwave Access (WiMAX) technology to bridge the digital divide between urban and rural areas.
Over the past three years the government has pumped more than NT$20 billion (US$647.5 million) into developing WiMAX and opened WiMAX frequencies to six operators.
But environmentalists yesterday urged more caution, saying electromagnetic radiation linked to WiMAX technology may have a negative impact on human health.
“WiMAX is a policy mistake,” Chen Jiau-hua (陳椒華), president of the Taiwan Electromagnetic Radiation Hazard Protection and Control Association, shouted before Ma left Exhibition Hall II of the trade center.
Chen, a professor at the Chia Nan University of Pharmacy and Science, said the government should think twice about boosting WiMAX technology because electric and magnetic fields from power lines, wiring and appliances are harmful to human health.
She cited an international study that found exposure to electromagnetic radiation may cause cancer and was likely responsible for an increase in childhood leukemia, although more research was necessary to establish the link.
Chen’s association has called on the legislature to pass a law banning the installment of wireless antennas in residential areas or near school campuses.
Mike Lin (林智清), who works for the Taipei Computer Association (TCA, 台北市電腦公會), dismissed the health fears, saying that electromagnetic radiation associated with WiMAX is lower than that for mobile phones. He said the National Communications Commission was of the same opinion.
WiMAX can transmit wireless data at high speed over long distances for computers or mobile phones. The wireless Internet service currently in use cannot maintain normal operations if a laptop is being used in a vehicle traveling at a speed of more than 50kph, but WiMAX chipsets enable laptops to remain connected to the Internet while moving as fast as 80kph.
DAMAGE REPORT: Global central banks are assessing war-driven inflation risks as the law of unintended consequences careens around the world, spiking oil prices Central banks from Washington to London and from Jakarta to Taipei are about to make their first assessments of economic damage after more than two weeks of conflict between the US and Iran. Decisions this week encompassing every member of the G7 and eight of the world’s 10 most-traded currency jurisdictions are likely to confirm to investors that the specter of a new inflation shock is already worrying enough to prompt heightened caution. The US Federal Reserve is widely expected to do exactly what everyone anticipated weeks ahead of its March 17-18 policy gathering: hold rates steady. The narrative surrounding that
Taiwan Semiconductor Manufacturing Co’s (TSMC, 台積電) share of the global foundry market rose to almost 70 percent last year amid booming demand for artificial intelligence (AI), market information advisory firm TrendForce Corp (集邦科技) said on Thursday. The contract chipmaker posted US$122.54 billion in revenue, up 36.1 percent from a year earlier, accounting for 69.9 percent of the global market, TrendForce said. Its share was up from 64.4 percent in 2024, it said. TSMC’s closest rival, Samsung Electronics, was a distant second, posting US$12.63 billion in sales, down 3.9 percent from a year earlier, for a 7.2 percent share of the global market. In the
At a massive shipyard in North Vancouver, Canadian workers grind metal beams for a powerful new icebreaker crucial to cementing the country’s presence in the increasingly contested arctic. Icebreakers are specialized, expensive vessels able to navigate in the frozen far north. And “this is the crown jewel,” said Eddie Schehr, vice president of production at the Seaspan shipyard. For Canadian Prime Minister Mark Carney, who heads to Norway next Friday to observe arctic defense drills involving troops from 14 NATO states, Canada’s extreme north has emerged as a strategic priority. “Canada is and forever will be an Arctic nation,” he said ahead of
Chinese entrepreneur Frank Gao used to spend long hours running his social media accounts but now outsources the chore to artificial intelligence (AI) agent tool OpenClaw, which is taking China by storm despite official warnings over cybersecurity. OpenClaw, created in November by an Austrian coder, differs from bots such as ChatGPT because it can execute real-life tasks such as sending e-mails, organizing files or even booking flight tickets. “Since January, I’ve spent hours on the lobster every day,” Gao said in an interview, referring to OpenClaw’s red crustacean mascot. “We’re family.” After downloading OpenClaw, users connect it to artificial intelligence models of their
