Vodafone Introduces Additional Anti-spam Measure

Vodafone K.K. has announced a new function will be introduced starting 30 March that blocks so-called “spoof mails”, mails sent via a PC with addresses posing as mobile handset mail addresses. With the new anti-spam measure, Vodafone K.K. aims to make its Vodafone live! mobile Internet service more dependable for customers. The spoof mail blocking function makes it possible to refuse mails sent via a PC that pose as mail addresses of Vodafone K.K., other mobile operator, or PHSNote 1 handsets. By accessing the Custom Mail Set-up page from either Vodafone live! or the Vodafone K.K. website (www.vodafone.jp), customers can select from the “accept (default setting)” or “refuse” settings to filter spoof mails.

Fujitsu Enables Prolonged Viewing of Digital Broadcasts to Mobile Phones

Fujitsu Limited today announced the development of a low-power analog to-digital (AD) converter that employs a delta-sigma(*1) modulator for mobile phones that are capable of receiving digital terrestrial television and radio broadcasts(*2). The new delta-sigma modulator-based AD converter can reduce power consumption levels of tuners embedded in mobile phones to 30 milliwatts (mW), approximately one-sixth to one-third the power drain of current levels, thereby enabling prolonged viewing of terrestrial digital broadcasting on mobile phones by significantly lessening the power consumption of mobile phone batteries. In addition, the integration of the new AD converter with OFDM demodulator (*3) onto a single chip is expected to facilitate the development of mobile phones that are more compact than currently available.
