Univ of Utah Figures Out Cloaking and Seeing Through Walls

There has been some very interesting work going on at University of Utah - I was not aware that they were doing so much work in this area. They reported what appears to be the first active cloaking method for various types of waves including microwaves and a low cost radio tomography method to image through walls. Active Cloaking: In recent years, scientists devised and tested various cloaking schemes. Experiments so far have been limited to certain wavelengths such as microwaves and infrared light, and every method tried so far has limitations. "We have shown that it is numerically possible...

Space Data Successfully Completes CDMA Balloon Flights

I had not heard of this company before but Space Data Corporation has announced that last month it conducted successful trials of its CDMA SkySite®, a major milestone in the development of economically practical wireless voice and data communications to large areas with sparse population. It is expected that each SkySite will be able to provide coverage over approximately 20,000 square miles. The use balloon platforms to position basestations in the sky to enable communications in remote areas that do not have coverage. During two trial flights, a prototype miniaturized CDMA 1X-RTT base station was carried aloft over a remote...

SA Report - Avago, Eudyna and WIN shake up GaAs rankings

The latest GaAs rankings are out from Strategy Analytics and there were several surprises especially from the international competitors. Avago Technologies, Eudyna Devices and Taiwan’s WIN Semiconductor made impressive gains in GaAs market share in 2008, ascending the top-ten list in the annual Strategy Analytics ranking of the world’s leading GaAs companies. RF Micro Devices remains the leading GaAs vendor by revenue, but its closest rivals - Skyworks Solutions and TriQuint Semiconductor - are pushing this market leader hard. GaAs Market Share (courtesy of Strategy Analytics) Lower down the ranks: • Avago Technologies overtook Anadigics as the fourth-ranked supplier in...

China’s 145 Million Unit Gray Market

Like many other illicit enterprises, China’s vast gray-market cell phone business is one of those things that many know about but few actually discuss it. iSuppli has reported that with gray-market shipments in 2009 set to grow to 145 million units, or nearly 13 percent of the size of the legitimate global cell phone business, the gray market has become too big and too lucrative for the mobile handset supply chain to ignore anymore. They report that China’s gray market wireless handset shipments are expected to amount to 145 million units in 2009, up 43.6 percent from 101 million in...

MIT Auto ID & Sensing Expo

The RFID Special Interest Group ran this event for the local RFID community at MIT in Cambrige, MA. The Expo provided a chance to educate, network and collaborate among the RFID community of the MIT Enterprise Forum so I could not resist attending this nice event in our own backyard. There were 2 keynote speakers, Sam Madden (Assoc. Prof at MIT) and Carlo Ratti (Dir, Senseable City Lab). Prof. Madden discussed the CarTel Mobile Sensor Network where they had built applications on top of a system of wireless car sensors riding on taxis and volunteer cars around the city. They...

AOC International Symposium & Convention

I am at the 46th annual AOC International Symposium & Convention in DC and saw most of the microwave companies serving the EW world yesterday. The top priority is still IED defeat systems and the AOC show daily stated that more than 36,000 devices have been fielded (that number surprised me as IEDs continue to be the biggest challenge to saving lives in Iraq and Afghanistan). An estimated $628 million is expected to be spent on the JCREW program alone over the next 10 years. Battlefield SIGINT is also important but does not seem to have as much priority...

MILCOM 2009 Kicks Off in Boston

MILCOM kicked off today starting with Plenary speaker Mr. David Gergen (Editor-at-large, U.S. News & World Report and Commentator, CNN) who discussed his views on how various presidents related to the military. He stated how past presidents from JFK to Bush Sr. all had military experience so they were familiar with the military where as more recent presidents since Bush Sr. did not have such experience so there was a learning curve as they got to know each other. He said the Obama is off to a good start with his strategic appointments from the military and Michelle Obama's...

Implantable Antennas/Power Amp Design

I attended the AnSys / Ansoft Smart Engineering Simulation Application Workshops earlier this week in Newton, MA. They had a complete RF/microwave track including sessions on Electrically Large Antennas and RCS ; Statistical Modeling, DOE and Optimization; HFSS Tips and Techniques; RF Power Amp Design Using Coupled Circuit, EM and Thermal Analysis; Method of Analysis for Implantable Antenna Systems and RF Product Mgmt . R oad Map and Dialog. The Power Amp Design was very interesting as they showed how you can model the chip and package separately and merge the results to simulate the device. Then with a link...

Power Amp Market to Double with MIMO 802.11n

Strategy Analytics reports that adoption of 802.11n MIMO with multiple transmit streams will help boost the market for Wi - Fi power amplifier modules to twice its 2008 size despite continued pricing pressure. “As prices for single-stream 802.11n (1 x 1) chips dropped to match 802.11g, OEMs have quickly begun to switch from 802.11g to 802.11n in new products. Consequently, 802.11n will ship in more than half of all Wi - Fi systems by the end of 2010,” says Christopher Taylor, Director of the RF and Wireless Components service. Not only will 802.11n quickly replace 802.11g, but as Wi -...

Unique/Novel Subjects at EuMW 2009

I like searching through the paper/poster topics for unique, novel subjects that are not main-stream and might be areas for future growth. I was able to attend a few of these talks but was busy with customer visits covering the exhibition which made it impossible to attend more of them. Here are some that I came across: Design of a Cellular Energy Harvesting Radio New Fabrication Process to Manufacture RF-MEMS and GaN on GaN/Si Substrate Design of a Fully Planar Chipless RFID Transponder with 35 Bit Data Capacity SP48T Module Architecture RF-MEMS Multi-Throw Switches for a Multi-Beam Antenna Measurement...
