Addressing the measurement issues related to WiMAX are key to ensuring its market success. Read how LitePoint offers multiple solutions to address R&D and manufacturing needs.
Multicarrier orthogonal frequency division multiplex (OFDM) signals are employed by 802.11a/g to support the highest data rates under the 802.11a/b/g standards. Christian Olgaard, LitePoint co-founder and VP engineering presents how they pose challenges that wireless LAN (WLAN) product designers and manufacturers should be aware of.
Carsten Andersen & Dick Walvis, members of the LitePoint technical staff. point out how using advanced WLAN test instruments, the designer can assess the impact of pulsed phase noise in the design tip.
Four different methodologies are used for testing MIMO WLAN chipsets and products. In this RF Design article, Dick Walvis and Sireesha Mallipeddi of LitePoint demonstrate how each methodology has its advantages and disadvantages.
As wireless USB makes its debut, designers are questioning if development and production testing align with realistic cost expectations. Onno Harms and Rob Brownstein of LitePoint explore in this article how using a test system built to capture and analyze wireless USB signals provides comprehensive test results that meet development and production needs within budget and time constraints.
Together, MIMO and WiMAX promise even greater data speeds but add hardware and software complexity to the mix. Onno Harms and Rob Brownstein of LitePoint address the challenge of minimizing costs while taking advantage of MIMO's benefits--and costs are more than just bills of materials.
EDNChina hears from Rob Brownstein, VP MR&C
Addressing the measurement issues related to WiMAX are key to ensuring its market success. Read how Christian Olgaard, LitePoint co-founder & VP engineering, shows that by optimizing the DUT's driver to generate non-linked based signals leads to test times many time faster than currently possible.
Implementing a common test platform and test methodology is an important step along the way. But, as Anita Chapman, business development director of LitePoint shares, the real time saver lies in the intelligence of the automated test software that runs on these systems.
Because MIMO technology presents technical hurdles to chipset vendors, Fan Liang, LitePoint director of field engineering, focuses on demystifying physical layer issues with MIMO and presents ways of improving MIMO performance.
Fan Liang and Onno Harm of LitePoint address how fast, accurate, and low-cost manufacturing test methodologies are essential for WiMAX technology to be productized.
Christian Olgaard, LitePoint co-founder & VP engineering, describes techniques to identify and troubleshoot the impacts of amplitude, phase, and group delay imbalances between the I and Q channels, phase noise, spurious signals and transient effects, and signal compression on transmitter performance.
Thomas Lecklider of Evaluation Engineering presents which MIMO test methodologies are most appropriate for varying test purposes along with the leading test solutions that address them.
Rob Brownstein, LitePoint VP MR&C, shares ways to optimize MIMO testing to overcome its challenges.
