The Opportunities and Challenges of LTE Unlicensed in 5 GHz
David Witkowski, Executive Director, Wireless Communications Initiative
In 1998, the Federal Communications Commission established the Unlicensed National Information Infrastructure or U-NII 5 GHz bands. These are used primarily for Wi-Fi networks in homes, offices, hotels, airports, and other public spaces and also consumer devices. U-NII is also used by wireless Internet Service Providers, linking public safety radio sites, and for monitoring and critical infrastructure such as gas/oil pipelines.

Future of Flexible Electronics
By Frost & Sullivan

Flexible Electronics are electronic products that are bendable or those that can be flexed. Most of the flexible electronic products are enabled by thin film metals such as silver. These flexible electronics are manufactured using roll-to-roll process. Some of the main products in the flexible electronics category are flexible displays, flexible photo-voltaic, flexible batteries, flexible sensors, flexible memories, and flexible radio-frequency identification devices (RFID).

Frost & Sullivan’s research in this space suggests that the major revenue for flexible electronics will come from consumer electronics that includes flexible display devices, flexible photo-voltaic (PV) and integrated portable electronic devices. Another important driver Frost & Sullivan observed is the “go green” initiative will likely encourage the large electronic companies adopting and initiate development of low-cost, low-footprint flexible electronic devices.

Frost & Sullivan research suggests that the flexible electronics market is estimated to around USD 1.7-1.8 billion and is projected to grow at a CAGR of around 40% to the year 2018.

Regionally, Asia-pacific is likely the key revenue contributor as our research suggests that a huge demand from the consumer electronics market is likely to be a major driver for the growth of flexible electronics market along with the global demand for lighter, flexible and smaller form-factor products that will mainly be enabled by the bio-degradable organic materials. These are some of the clear drivers for the penetration and growth of flexible electronics from the year 2014. The pie-chart showcases the segment breakdown for flexible electronics and as seen in the chart in Figure 1.

Frost & Sullivan observes that the flexible electronics market is likely to grow however, strategic partnerships with research institutions, material developers and equipment suppliers is a major step in establishing the manufacturing of flexible electronics and poses a big challenge for time-to-market. Also, due to the high cost-competitiveness of conventional electronic devices, flexible electronics will do well in newer application areas or devices than trying to penetrate the existing devices or markets.

Also, Flexible electronics deliver a low-cost solution, mainly due to the adoption and implementation of conventional printing techniques in the manufacturing process. But the different substrate materials used come with different challenges and existing technologies have been designed to handle rigid substrates, such as silicon and glass.

Plastic substrates are quite flexible, and hence their careful handling is critical to avoid any major issues with respect to the substrate material. Similarly, plastic substrates suffer from melting temperatures that are far below those used in traditional processing techniques.

Therefore, it is of prime importance to choose the appropriate polymer that has thermal stability along with other properties required for a material to serve as a flexible substrate.
Technology: With the focus on performance and efficiency as the points of differentiation in the market, all participants are offering technologically advanced products that will help distinguish their brands.

Frost & Sullivan tracks the technology roadmap as given in the chart below between 2008 till 2018.

Uncertain Times for DefenseOpen’s Systems and Changes in DoD Procurement: This Time It’s Real
By Barry Manz

The U.S. Department of Defense has a well-earned reputation for inertia. Many proposals for change are made – but nothing happens. The COTS initiative, which promised cost savings through the use of off-the-shelf commercial parts, sounded terrific at the time. It heralded a major departure from standard DoD procurement that more or less guaranteed that every system would be different in part because it used parts that were developed from scratch, leading to “one-off” systems that were very expensive.
