The Network Centric Operations Industry Consortium (NCOIC), a major international, industry-wide consortium, has been announced, combining the technology and expertise of 27 major companies to recommend a unified approach to creating a global network centric environment. The NCOIC was created in response to customer requests that industry assume a...

According to ABI Research, building on the strength and popularity of Wi-Fi, meshing networks extend range, security and redundancy by augmenting traditional infrastructure-to-user communications with enhanced peer-to-peer communications. This is accomplished through an advanced addressing scheme that better handles ad hoc communications and handoffs. Issues currently plaguing meshing networks...

Opportunities for the emerging 802.15.4 Wireless PAN (WPAN) technology, and the imminent ZigBee network layer, look promising according to In-Stat/MDR. Using an aggressive scenario, annual shipments will surpass 150 million units in 2008. And, based upon discussions with system providers, the high tech market research firm believes that the...

Being the wireless technology that can deliver the bandwidth and QoS that many consumer electronics companies have been looking for, Ultra-wideband (UWB) presents attractive opportunities, primarily for fast video transfer between peripheral devices, such as digital camcorders, TVs and PCs, and between set top boxes and TV monitors. In-Stat/MDR...

Microwave Ring Circuits and Related Structures Second Edition Kai Chang and Lung-Hwa Hsieh Wiley Interscience 377 pages; $125 ISBN: 0-471-44474-X Ring resonators have been used extensively in microwave circuits such as filters, oscillators, mixers, couplers, power dividers/combiners, antennas and frequency selective surfaces. They are also useful in various techniques...

A satellite that will enable future air navigation enhancements has been deployed by Lockheed Martin. The payload is the first use of the GPS L5 civil navigation frequency for the Federal Aviation Administration (FAA), and supports a move toward satellite-based navigation to make air traffic management safer, more reliable...

A new family of patent-pending high Q ceramic resonators has been introduced that sets a new standard for Q and ease of circuit integration for chip and wire, or SMT assemblies. The technology is ideally suited to the stabilization of microwave oscillators and VCOs, and low loss narrow band...

A new high voltage, high power InGaP HBT discrete device has been developed that can significantly improve the efficiency of power amplifiers (PA) in cellular base stations. This new technology provides superior performance compared to silicon LDMOS. A 30-watt device driven by a predistorted W-CDMA signal has demonstrated 45...

The use of simulation software is becoming an essential part of the design cycle of any new device, and has allowed the concept of “virtual prototyping” to become commonplace. Not only does this provide engineers with the ability to test new ideas before building prototypes, it also allows for...

A multi-band, multi-waveform software defined radio (SDR) that provides programmable and re-configurable communications is at the core of ad-hoc networks, and ad-hoc networks are key to the transformational needs of the military (manned and unmanned). To meet interoperability requirements and mitigate co-site interference issues of a multi-band, multi-waveform architecture,...
