Cell Phone Radiation Report Out

Last year around this time there was some renewed concern that cell phone radiation could be dangerous, especially to kids. The Environmental Working Group has brought up the subject again with their release of the best and worst phones for radiation emissions and bringing up their concerns of the possible dangers. But there still does not seem to be any scientific evidence that they are dangerous and non-ionizing radiation is not known to be dangerous to the human body at the levels one would experience in everyday use of cell phones. It is interesting that Samsung dominated the top 10...

WiFi is Pushing RF ICs to New Heights

Strategy Analytics states that vendors will ship $4 billion in Wi - Fi radio chips in 2013, most of these for cellphones, notebooks, netbooks , infrastructure, home entertainment systems and wireless gaming consoles. At the same time, 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. They have determined that Broadcom will probably remain on top, but the firm faces increasing competition from cellular chip vendors bundling connectivity with their platforms, and from chip specialists targeting emerging applications, such as...

461 GB of Data Per Day Sent Back to Earth!

Over the next year NASA’s Lunar Reconnaissance Orbiter (LRO) will scout and collect more information about the moon's surface and environment than any previous mission. It takes a powerful system to send all of this information more than 238,800 miles back to Earth so equipped with a new type of TWT amplifier, LRO can transmit 461 GB of data per day. It transmits this information at a rate of up to 100 MB per second. The 13-inch-long TWT is the first high data rate Ka-band transmitter to fly on a NASA spacecraft. L-3 Communications Electron Technologies built the amplifier under...

Wireless Temperature Sensors in Football Helmets

There have been 40 deaths (30 high school players) to football players due to over heating since 1995. Now wireless transmitter systems are being tested that are embedded into football helmets with temperature sensors to monitor player's body temperature. The cost is about $100 per player - pretty cool stuff. See the video below from CBS:...

First American Recieves WiFi Implanted Pacemaker

Carol Kasyjanski has become the first American recipient of a wireless pacemaker that allows her doctor to monitor her health automatically over the Internet. The wireless home monitoring system collects the data through a WiFi connection and transmits it over the Internet to her doctor. The server and the remote monitor communicate at least once a day to download all the relevant information and alert the doctor and patient if there is anything unusual. Now when she visits the doctor, about 90% of the tests are already completed from the data collected. She has suffered from a severe heart condition...

August SatCom Issue

Euroconsult states that growth in the fixed satellite market has remained strong despite the adverse economic environment. According to their latest forecast, the fixed satellite sector grew in terms of both transponder demand (+9%) and overall revenues (+10.7%) representing a peak in the current decade. Digital entertainment and emerging digital markets remain the primary growth drivers, with corporate networks, military communications and broadband access uptake also contributing to growth. Our August Satellite and mmWave themed issue is live online today with the cover feature focusing on the Mil SatCom Capacity Crunch. It includes survey responses from companies in the...

"Cool" New Material for Power Electronics

Researchers at GA Tech Research Institute ( GTRI ) are developing a novel heat-transfer material for powerful radar systems with a goal of removing heat up to 100 times more effectively than present materials. The novel material is a composite of diamond and copper that is trying to achieve thermal conductivity of up to 20,000 watts per meter K compared to 200-300 watts per meter K for copper. This would be achieved by using a materials systems approach that would also include liquid cooling. The project is funded by DARPA targeting high power T/R module packages. For more details,...

Satellite Sector is Growing

Euroconsult recently announced that growth in the fixed satellite market has remained strong despite the adverse economic environment. According to Euroconsult’s soon-to-be-released report, the fixed satellite sector grew in terms of both transponder demand (+9%) and overall revenues (+10.7%) representing a peak in the current decade. Digital entertainment and emerging digital markets remain the primary growth drivers, with corporate networks, military communications and broadband access uptake also contributing to growth. According to the report growth in transponder demand remained particularly strong in emerging satellite markets, which include Latin America, Africa, Central Europe and large parts of Asia. These regional markets...

What Ever Happened to Radio Interoperability???

After the 9/11 disaster, the government allocated significant funding for homeland security with a large amount allocated toward interoperable communications. It seemed like it took a a year or two but a good amount of the money eventually became available. Most critical communications companies offer interoperable solutions from simple patches to full IP -based systems. But I have not heard of any significant progress in deploying these systems especially at the federal level where solutions could offer interoperability nation wide. What ever happened to our priorities here? New York was suppose to roll out a state wide system being supplied...

RFID Positioned for Growth

There were a couple of significant RFID news items this week. The first was a report indicating that the global radio-frequency identification ( RFID ) market is growing despite the fact that the world’s largest RFID project - the $6-billion China National ID card scheme - was completed a year earlier. According to IDTechEx , the global RFID market is rising 5 percent this year to $5.56 billion. Most of the action has been in the US, where the largest orders continue to be placed, as well as in the UK, China, and Japan. The second was a contract for...
