A company based in the US' Silicon Valley, backed by Taiwanese cash and brainpower, launched a new component that may advance mobile-Internet solutions.
"This small package represents a technical breakthrough in size and thermal performance," EiC Corp's Larry Wang said in Taipei yesterday.
The Fremont California-based company announced a series of new modules that amplify data signals on mobile phones and significantly increase download speeds.
The fingernail-sized square chips work in GSM, GPRS, CDMA and other mobile-phone standards.
Taiwan-based chip design firm Etron Technology Inc (
Etron invested US$50 million for a 23 percent stake in the company, and Hon Hai Precision Industries and Yu Long Motors are also major investors, according to Nicky Lu (
The new modules amplify mobile-phone signals, allowing them to operate faster.
Some of Motorola's mobile phones geared toward GPRS can download data at a rate of 24 kilobits per second -- about half the speed of a standard computer with a 56k modem.
With EiC's new power amplifier module, the speed can theoretically be doubled while also dissipating heat at the same time, according to Barry Lin (林嘉孚), vice president of production at EiC.
Heat and bandwidth have been the main restrictions on wireless Web performance.
The faster data is transmitted through a cellphone, the hotter it gets. Mobile phones are designed to run slower in order to avoid overheating, seriously inhibiting their performance on the Internet.
To pump up the speed, the EiC module helps dissipate heat as it doubles the amount of slots used in downloading information.
Current handsets use only two slots, while EiC's module doubles the amount of slots to four, greatly increasing data transmission speed.
Phone companies do not necessarily like use of more slots and higher speeds because it pressures them to install more base stations in high-use areas.
Just as computer Internet connections slow down when too many people log on at the same time, cellphone base stations pumping out signals slow down when too many people download videos, data or browse the Internet on a cellphone.
To make planned wireless Web services a reality on GPRS and 3G, download higher speeds are required.
Lu said his firm launched the product in Taipei because the technology is aimed at manufacturers in China, Japan, South Korea and Taiwan.
The company has already started shipping samples of the new power amplifier modules, dubbed the ECM007 and ECM009, to customers in Asia and is ready to ramp up production as soon as the products gain wider industry acceptance.
HEAVY INVESTMENT: Moody’s affirmed the firm’s ‘Aa3’ rating with a ‘stable’ outlook due to its leading position in the industry and ability to match customer requirements Taiwan Semiconductor Manufacturing Co’s (TSMC, 台積電) revenue this year is expected to increase about 21 percent to NT$1.29 trillion (US$44.01 billion) from NT$1.07 trillion last year, driven by strong demand for advanced 5-nanometer and 7-nanometer chips mainly used in smartphones and high-performance computing devices, a Moody’s Investors Service report on Wednesday said. TSMC’s rate of revenue growth next year is to increase to 7.5 percent, the ratings agency said. The company, which supplies 5-nanometer chips for Apple Inc’s new iPad series, has introduced the advanced chips ahead of its competitors and gained a significant share of the market for the foundry industry’s
NO VIRUS BLUES: A SEMI Taiwan official said that the virus does not slow down the global semiconductor industry’s investment in manufacturing equipment The production value of the nation’s semiconductor industry is expected to grow 16.7 percent this year from last year, outpacing the global industry’s 3.3 percent growth, industry association SEMI said yesterday. That would help Taiwan safeguard its second spot in the global semiconductor market with a production value of more than NT$3 trillion (US$102.73 billion), SEMI Taiwan president Terry Tsao (曹世綸) told a media briefing in Taipei for the Semicon Taiwan trade show beginning today. The global semiconductor industry’s production value is expected to increase to US$426 billion this year, SEMI said. In terms of semiconductor equipment investment, equipment billings from Taiwanese firms
Intel Corp has received licenses from US authorities to continue supplying certain products to Huawei Technologies Co (華為), a company spokesman said yesterday. Washington has been pushing governments around to world to squeeze out Huawei, saying that the telecom giant would hand data to Beijing for espionage. From Monday last week, new curbs have barred US companies from supplying or servicing Huawei. This week, the state-backed China Securities Journal reported that Intel had received permission to supply Huawei. China’s Semiconductor Manufacturing International Corp (SMIC, 中芯國際), which uses US-origin equipment to make chips for Huawei and other companies, last week confirmed that it had sought
Taipei Times: When do you think the hospitality industry can return to how it was before the COVID-19 pandemic? How does Formosa International Hotels Group (FIH, 晶華酒店集團) fare this quarter and beyond? FIH chairman Steve Pan (潘思亮): The virus outbreak will have a serious impact on business travel, driven mainly by meetings, incentive travel, conferences and exhibitions over the past three decades. For the past six months, many businesspeople have grown used to exchanging information on the Internet, where more people can participate. The trend might sustain for three to five years until people are vaccinated and it is safe to
