A common feature in smart phones today is GPS. However, accuracy is not
always trustworthy, limiting the capability and reliance by users. This
can be caused by a number of reasons, one of which is poor GPS antenna
performance. Today, there is no certification standard for A-GPS using
over the air (OTA) testing which allows sub-par solutions to enter the
market. CTIA has broadened the scope of the test plan for OTA
performance to include A-GPS.
Spirent Communications, a mobile device, application, and wireless
network testing company, has partnered with ETS-Lindgen, a provider of
RF chambers and antenna measurement solutions, to integrate Spirent's
UMTS Location Test System (ULTS) with ETS-Lindgren's EMQuest Antenna
Measurement Software. This will enable the ability to test product in
compliance with the upcoming 3.0 release of the CTIA's Test Plan for
Mobile Station Over the Air Performance, which will become mandatory on
all CTIA authorized test labs.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
