In Favor of Fading Channels
When David Tse's mobile phone drops out in the middle of a conversation,
he doesn't curse his wireless carrier. According to the Department
of Electrical Engineering and Computer Sciences professor, channel
fading is the key to building high-bandwidth wireless networks.
Downsizing Sensor Software
In the lush habitat of nesting seabirds, dozens of tiny electronic sensors measure humidity and temperature. Meanwhile, in the Intel Research Laboratory in downtown Berkeley, the same sensors are embedded in office chairs to track movement. While seemingly disparate locales, both the seabirds' natural habitat and a bustling research facility are ideal testbeds for the distributed, dynamic, and adaptive software brains behind tiny wireless sensors.
The Next Next Generation of Mobile Service
The Service Architecture for Heterogeneous Access, Resources,
and Applications (SAHARA) project is poised to reinvent nearly
every aspect of mobile telephony service. The result of this massive
technology and logistical undertaking could be mobile services
that are always available, accessible, inexpensive, and actually
useful.

The Golden Age of Wireless Research
The Berkeley Wireless Research Center is rich with ambient intelligence. And the smarts aren't limited to the dozens of researchers toiling over their keyboards and lab benches inside the 12,000 square foot downtown Center. The BWRC's goal is to integrate and implement technology to bring the power of high-bandwidth and ubiquitous communication into the built environment.
Great moments of innovation from the annals of
Berkeley Engineering history.
