Living Through Our Cell Phones — Louis E. Frenzel March 11, 2008 The 60 GHz Promise Land . . . Or Is It? — Louis E. Frenzel February 12, 2008 Wireless System Update For February 2008 I have always been amazed by how much difference a good antenna makes in a wireless application. It became pretty clear to me at an early age as a ham radio operator that a good antenna is the difference between making a connection or not. But now, having stated the obvious let me say that designing a new antenna is just as much art as it is a science. — Louis E. Frenzel January 2, 2008 Wireless System Update For January 2008 There are literally dozens of methods used in transmitting data wirelessly over short distances. Here is a look at what is happening with some of the more commonly used standards like Wi-Fi, Bluetooth, UWB, and ZigBee. — Louis E. Frenzel December 4, 2007 Wireless System Design Update For December There are a couple of subjects I never got around to this year in WSD, specifically the Google cell phone possibilities and femto cell's potential. None of this exists at the moment except for some trials here and there, but you will be hearing more about them in the coming year. Here is a look at what to expect. — Louis E. Frenzel November 6, 2007 Wireless System Design Update For November Have you become dependent on your cell phone? Do you feel naked without it? Has your cell phone become a source of entertainment as well as just a way to make a phone call? Most of you would say yes to all those questions. Which is why the cell phone business has grown so big and continues to get bigger... — Louis E. Frenzel October 9, 2007 Wireless System Design Update For October It was 50 years ago October 4th that the first successful satellite was put into orbit. Launched by the Russians, this satellite called Sputnik, as basic as it was, set off a stream of events that could not have been anticipated. Besides starting the space race, launching the satellite industry, revolutionizing the telecommunications business, and intensifying the cold war, this satellite had so many unintended consequences, good and bad, it is hard to identify all of them... — Louis E. Frenzel September 11, 2007 Wireless System Design Update For September 2007 If you are a wireless wonk like me, you have been following the story of how the FCC has been deciding upon the rules for its upcoming spectrum auction. Thanks to some horrendous lobbying by cell phone carriers, Google, and a host of others, FCC Chairman Kevin Martin and the other four commissioners have decided on how the spectrum should be sold and used. If you have not been following this whole process, you should take a look at what is going on... — Louis E. Frenzel August 7, 2007 Wireless System Design Update for August 2007 The IEEE established the 802.20 wireless mobile broadband group in 2002 and work began and progress was made. But the big question is: Whatever happened to this project? Now I know, so I can tell you about it. — Louis E. Frenzel July 10, 2007 Wireless Systems Design Update for July 2007 Choosing the Right Memory For Your Cell-Phone System — Louis E. Frenzel July 10, 2007 Wireless Systems Design Update for June 2007 Third Method Of UWB Solves The Home Networking Problem — Louis E. Frenzel May 9, 2007 Wireless System Design Update for May 2007 ZigBee Modules Simplify Adoption In Industrial Network — Louis E. Frenzel , et al. April 10, 2007 Wireless System Design Update for April 2007 Breakthrough Modulation Method Minimizes Bandwidth At Any Speed — Louis E. Frenzel , et al. March 6, 2007 Wireless System Design Update for March 2007 Shortwave Radio Jumps On The Digital Bandwagon — Louis E. Frenzel , et al. February 6, 2007 Wireless Systems Design UPDATE for February 2007: Newest Wireless Standard Gives Designers Choices, Not Compromises — Louis E. Frenzel , et al. January 9, 2007 Wireless Systems Design UPDATE: January 9, 2007 The history of the development of radio technology doesn't rest in the hands of one man. As with any technology, countless inventors, designers, and developers contribute to what becomes today's status quo... — Louis E. Frenzel December 5, 2006 Wireless Systems Design UPDATE: December 5, 2006 The good news is that ultra wideband (UWB) wireless is finally here. The bad news is...well, I can't think of any bad news. UWB chip vendors finally have working silicon. Now they are announcing their FCC approvals and WiMedia certification and registrations, as well as identifying some initial customers... — Louis E. Frenzel November 9, 2006 Wireless Systems Design UPDATE: November 9, 2006 As wireless devices have continued to move to higher and higher frequencies, antennas thankfully have gotten smaller. Now instead of the "whip" antenna that used to be a common sight on cordless phones, cell phones, and other wireless devices, antennas are typically totally internal. If you see any vestige of an antenna on a product, it is a small protrusion at most. But that does not make it any less important... — Louis E. Frenzel October 10, 2006 Wireless Systems Design UPDATE: October 10, 2006 — Louis E. Frenzel August 8, 2006 Wireless Systems Design UPDATE: August 8, 2006 As I was trying to think of a topic to write about this month, my mind wandered off into contemplating what this world would be without wireless. A heavy duty "What If" brain exercise for sure. Maybe discussing, or even thinking about, something that is not real is a huge waste of words, but it does make you appreciate what wireless has given us. — Louis E. Frenzel  prev. page
