Development of Muli-band Power Amplifier for Mobile Phone by DOCOMO

January 14, 2010 · Filed Under Trendy Products · 1 Comment 

DOCOMO multi-band power amplifierNTT DOCOMO made an announcement on development of a multi-band power amplifier prototype capable of amplifying 8 different frequency bands ranging from 700 MHz to 2.5 GHz. Use of power amplifier in mobile phone is to increase signal power to a level that is required for given wireless communication protocol. Accommodating multi-band capability inevitability increases the mobile phone’s size for a simple fact of employing a separate single-band amplifier for each band. However, DOCOMO’s newly developed prototype is capable of 8-band operation through use of matching circuits where the frequency characteristics are controlled by multiple semiconductor switches to accommodate the required frequency band.

Development of Solutions for Combating Silent Failure in IP Networks by DOCOMO and Fujitsu

December 16, 2009 · Filed Under Trendy Products · Comments Off on Development of Solutions for Combating Silent Failure in IP Networks by DOCOMO and Fujitsu 

In an IP network silent failure occurs when a router fails and as a result of this data transmission is stopped all without the network administrator being notified. This phenomenon is due to the fact that routers are not capable of detecting their own internal failures. The current solution to overcome this issue is for network operators to install dedicated monitoring devices capable of detecting silent failures through continually transmitting test data throughout the entire network and analyzing the test result, a rather time consuming process indeed. Based on this need, DoCoMo and Fujitsu have jointly developed two new technologies capable of detecting and locating “silent failures” within IP networks with greater speed and accuracy than currently available methods. One of these newly developed technologies is responsible for analyzing not only the test transmitted data but also analyzing such information as loss rate and network delays which would results in faster detection of silent failure. It is also capable of detecting warning signs of silent failures that would possibly about to occur. Read more
