Caution: MIMO Test Challenges Ahead

August 19, 2010 12:41 pm | by Greg Jue, RF Applications Specialist, Agilent Technologies | Articles | Comments

It wasn’t all that long ago that Multiple-Input Multiple-Output (MIMO) technology first captured the cellular industry’s attention by promising higher data rates for a single user using two or four streams of data transmitted (and received) with multiple antennas.

Have the rapid technological changes of the past decade negatively or positively impacted the timing solutions market place?

July 25, 2010 8:08 am | by Jim Holbrook, General Manager, Networking and Communications Timing at IDT | Articles | Comments

One of the most significant technological changes that has occurred in the past decade has been the shift from parallel to serial busses for high-speed system I/O and also for chip-to-chip interconnect. Examples of this trend are: •PCI Express for PCs, servers and increasingly in networking and communications platforms •Serial RapidIO for wireless base stations •Infiniband and Fibre Channel for data centers •VITA 46.

WiMAX and LTE continue to pose many unanswered questions. Q: What common or overlapping technologies do WiMAX and LTE have in common and will they ever converge for certain applications? By Joe Cozzarelli, Senior Director Broadband RF Products and Glenn Eswein, Director of Product Marketing, Broadband RF Business After three years of deliberation, the IEEE802.


Power Efficiency

July 15, 2010 12:06 pm | Articles | Comments

The path to achieving energy efficiency is ridden with obstacles. Q: If we continue to increase the power efficiency of a product, are we approaching the point of diminishing returns? Will it eventually detrimentally impact the cost of the product? Doug Bailey, VP marketing, Power Integrations This is an interesting question.

WiMAX and LTE: Closer than You Think

May 19, 2010 11:04 am | by Joe Cozzarelli, Senior Director Broadband RF Products and Glenn Eswein, Director Of Product Marketing, Broadband RF Business, ANADIGICS | Articles | Comments

After three years of deliberation, the IEEE802.16m air interface definition will be ready for prime time in the next few months. This critical step toward creating true 4G cellular technology based on WiMAX is important enough to earn compliant products a new name: WiMAX 2. Further proof came last month, when an impressive subset of the WiMAX community created the WiMAX 2 Collaboration Initiative to "improve the economics of mobile broadband" and "to create a better value chain for service providers.

All indications are that LED backlights will be the preferred light source in mobile applications in 2011, representing a significant growth opportunity for OEMs and the entire backlight and panel supply chain. Do you see the role of LEDs in wireless products changing as the technology matures? By Vandana Lokeshwar, Technical Marketing Manager, Newark Attention is now shifting away from achieving raw light output that matches incandescent bulbs, to increasing the number of lumens per electrical watt supplied.

How can Wi-Fi interoperate with WiMAX and LTE?

December 14, 2009 11:47 am | Articles | Comments

Welcome to Brainstorm! While Wi-Fi technology has proven to be largely successful in providing inexpensive wireless Internet service within close proximity to the Wi-Fi access point, WiMax technology could expand the potential of wireless penetration and connection quality. Ashish Sharma, VP Corporate Communications, Alvarion Wi-Fi technology has proven very successful for short range broadband connectivity for hotspots, residential homes and enterprises all around the globe, providing inexpensive wireless internet service within close proximity to the Wi-Fi access point through the use of license-exempt frequency bands.

How does a reputable component supplier guard against counterfeit components?

December 14, 2009 11:47 am | Articles | Comments

Welcome to Brainstorm! The detection of counterfeit components has become increasingly difficult. The majority of parts have the same or similar markings as their qualified counterpart. In many cases, the identification of major manufacturers is applied despite manufacturers' efforts at product differentiation.
