MIMO’s Challenges When Evaluating WiMAX Equipment

December 12, 2007 7:49 am | Product Releases | Comments

WiMAX employs Multiple Input Multiple Output (MIMO) technology to improve system performance by either increasing signal-to-noise ratio or data throughput or both. Implementation of MIMO requires an unprecedented collaboration of RF and high-speed digital signal processing technologies and complex software and presents new challenges for design engineers at all levels of product development....

Bluetooth Secure Simple Pairing

December 12, 2007 6:07 am | Product Releases | Comments

The existing method of pairing Bluetooth devices generally consists of several steps, such as searching for the device, connecting to it and authenticating the device to make sure it is the correct device. In the pre- 2.1+EDR compliant Bluetooth devices (legacy devices), in order to simplify the user experience, the products used an authentication procedure, which is vulnerable to simple security attacks....

Integrated EMI Filters and the Need for More Bandwidth

December 12, 2007 5:36 am | Product Releases | Comments

In previous generations of cell phones, when the design called for more data to be moved around, the solution was to add more data lines. Only a handful of data lines were sufficient at first, since there was only basic numeric data to be displayed and data rates were rather low. We all remember the old analog flip phones with their LED displays, you pushed the keypad and a digit appeared....


Standard sRIO Feature Use in baseband

December 12, 2007 5:36 am | Product Releases | Comments

Today, serial RapidIO (sRIO) has become the embedded interconnect of choice for designers everywhere. At the forefront of driving this adoption is the wireless telecommunications infrastructure, particularly the baseband. Evidence of this fact comes from major OEMs around the world who are now in production of system designs based on the serial RapidIO specification, versions 1....

Boosting Bluetooth to 250 Mb/s with Ultra-Wideband

December 12, 2007 5:36 am | Product Releases | Comments

After significant analysis of high-speed technologies, last year the Bluetooth SIG selected WiMedia-based ultra-wideband (UWB) for a new, fast wireless specification. Originally conceived as a short-range, low-power, low data rate cable replacement for audio headsets and keyboards, the new, high-speed Bluetooth opens up a world of opportunity to capture and share our lives through images and sound—such as printing high-res pictures directly...

Mining RFID's Potential to Track Ore

December 12, 2007 5:04 am | Product Releases | Comments

Typically, mining companies such as CVRD Inco use a labor-intensive, inexact process to determine ore yields and grades. By improving the accuracy of such information, CVRD Inco believes it could optimize the mix of chemicals it uses to produce nickel, copper, cobalt and other metals. That's why the Toronto-based mining company is testing an ultrahigh-frequency (UHF) RFID system at its Stobie Mine in Sudbury, Ontario, incorporating EPC Ge...
