Since I first got my feet wet in the RF and microwave business about 12 years ago, I've heard the promise of a single phone, single phone number, for each person. I recall spending time in development labs with enthusiastic engineers showing me a cordless DECT phone that showed promise for the beginnings of being a cordless phone in your house, and converting to a wireless phone when you get out of range.
Now it seems that the path to the single phone is to combine cellular service and WiFi. There seems to be plenty of these phones available. I'm wondering, what's the real buzz, do they work well? Better yet, have any of you designed one? If yes, do you wish there had been a better part to get the job done? Click on over to the forum and let us know about your WiFi/cellular design challenges.
I love Bluetooth. Little did I know, seventeen years ago when I was assigned my first project to write about the origins of Bluetooth and the viking that inspired the name that it would bring so much joy and convenience to my life
The main point of this blog is to point out that there is a major shift in LDMOS technology for cellular applications and the device operating voltage is changing from the current 28V range up into the 48V region.
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.
