Nancy Maas Editor-in-Chief There is an interesting topic being debated on various industry blogs right now. One that is very polarizing and may impact the semiconductor industry far beyond what we have seen thus far. The critical question seems to be: How long will Moore's Law be reliable? Moore's Law, named after Intel Corporation co-founder Gordon Moore, states that the number of transistors that can be placed on an integrated circuit doubles roughly every two years.
Planning and designing an integrated wired/wireless network before construction begins pays big dividends later. By Ahmet Tuncay, Trapeze Networks and Paul Kish, Belden. click to enlarge Figure 1. Additional cabling from wiring closet switches to Wi-Fi mounting locations in ceilings should be accounted for in the initial cabling plan, leaving a 15- to 20-foot service loop at the end as wiggle room in case AP locations later require adjusting.
By Benjamin Zarlingo, Agilent Technologies Inc. In designing, troubleshooting and optimizing WiMAX Wave 2 systems, a variety of dual-channel measurements can provide essential insight into their operation and performance. click to enlarge Table 1.
Nancy Maas Editor-in-Chief Did you know that the cumulative electricity bill savings enabled by semiconductors might exceed $1.3 trillion through 2030? Semiconductor technologies are so essential to advances in energy efficiency gains that the U.
Securing product performance in the field by using laboratory channel emulation can give a competitive edge to companies that use these solutions. By Janne Kolu, Elektrobit Corporation click to enlarge Figure 1. Emulation of a radio channel in the laborotary conditions.
By Mike Green, European Correspondent Wireless Design & Development The year 2009 is set to be the toughest year to date for European mobile operators. They are facing a fully saturated market, declining voice revenues due to hyper-competition, and a subscriber base that is going to attempt to cut its expenditure on all non-essentials.
By Steve Cooper, Axis Network Technology WiMAX has recently come of age with two significant network roll-outs being implemented (one in Moscow and another in Baltimore), and the announcement of the imminent availability of a number of WiMAX-equipped notebook PCs and handheld terminals.
Aftermarket vendors may resort to practices that compromise the end user experience or safety to make battery packs inexpensive and attractive to the consumer. Jeffrey VanZwol, Micro Power Electronics Figure 1. Insufficient welds that are not fully on the tabs.
Diverse modulation formats and sampling rates between various standards make designing common building blocks challenging. Deepak Boppana, Altera Corporation click to enlarge Figure 1. Farrow Filter Structure. Remote radio heads (RRH) technology with support for simultaneous operation of multiple air-interface protocols is an emerging product requirement for operators.
EPC-compliant RFID UHF tags deliver accurate, affordable and unique identification. They create real-time visibility for identifying and tracking objects moving through the supply chain or on and off the shelves. But there are many different types of tags and formats to choose from, depending on the application.
Nancy Maas Editor-in-Chief Every morning we wake up to a barrage of reports on the global state of the economy and how it is impacting our citizens, our government as well as nations around the world. One day the market is up and showing possible signs of recovery; the next day the market takes back any profits we made the previous day and the media is again reporting all "doom and gloom.
With the integration of MEMS technology in the remote, motion signatures can be digitized for the game control. By Michelle Kelsey, Freescale Semiconductor The evolution of gaming is on its way - Freescale's accelerometer, MCU and radio portfolio enables an ideal chip set for low power with high integration.
