Whatever Happened To 802.20? Communications/Test Editor Lou Frenzel takes a look into the ins-and-outs of passing new IEEE standards and what happened to 802.20 - the group that fell by the wayside... — Louis E. Frenzel January 9, 2007 Marconi Did Not Invent Radio 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 January 9, 2007 Wireless Fights The Battle For Video Networking In The Home Video transmission demands superior technology, and wired connections are handling the load. Can wireless catch up, or will technological limitations beat consumer desire? — Louis E. Frenzel January 9, 2007 My Best Christmas Gift Was Wireless Lacking wireless Christmas tree lights, one can settle for the next best thing: wireless Christmas gifts! Lou Frenzel had a very merry Christmas. — Louis E. Frenzel July 11, 2006 The Optical Option Not all wireless is RF. As a wireless system designer, when seeking a wireless solution you should always keep in mind that you can use free-space optical (FSO) tools to get you from here to there without wires. Your first thought of an optical solution is probably a TV remote control or the short range infrared (IR) like those IrDA links used in some of the older PDAs, laptops, and other devices... — Louis E. Frenzel June 6, 2006 The Enigma Of WiMAX I’ve always tried to stay positive about new wireless technologies. I’m still positive about WiMAX (mercifully short for Worldwide Interoperability for Microwave Access), but it really is hard to say where this slick technology is headed... — Louis E. Frenzel May 8, 2006 UWB Bluetooth In case you have not heard the news, Bluetooth, the king of short-range wireless, will get a new physical layer option soon. We normally associate Bluetooth with low-speed ad-hoc networks and cell phone headsets. Now with the decision to add ultra wideband (UWB) as a new air interface... — Louis E. Frenzel April 3, 2006 Telepathy… The Future Wireless Okay, I can already feel some of you pulling away from me as you click by the title. But just hold on a nanosecond. Your attention span can’t be that short. Stay with me here. How do you know that telepathy isn’t the future of wireless? If you try to predict the future of wireless, why wouldn’t you come to the conclusion that telepathy is one of the more attractive options? Research has revealed some amazing things about telepathy. If you’re willing to read on, I’ll elaborate... — Louis E. Frenzel March 6, 2006 The Bluetooth-UWB Crossbreed You may have heard of the Bluetooth SIG’s announcement last year that it was considering Ultra-Wideband (UWB) for the next step along its roadmap to higher data speeds. In looking for a new physical-layer (PHY) option, the group chose an existing wireless technology rather than develop something new on its own... — Louis E. Frenzel February 6, 2006 UWB Versus Wi-Fi: The Battle for Video Transport One of the hottest topics today is wireless video. Conference discussions are plentiful, and companies are announcing various products and services. Many of these developments center on cell-phone video. Haven’t we all wondered who would want to try to watch TV on such a small screen... — Louis E. Frenzel January 8, 2006 Near Field Communications Brings New Meaning To Short-Range Wireless The neat thing about wireless communications is that there is literally something for everyone. There is a technology, protocol, or standard for virtually any wireless need or application. And just when you think we have it all pretty much covered, a new technology comes along to give you one more option. One of the newer options is near field communications (NFC)... — Louis E. Frenzel December 4, 2005 EMI From Hell Electromagnetic interference (EMI) is a problem for all wireless engineers. If you aren’t generating it and having to control it, then you’re trying to overcome the EMI from other sources. As a wireless engineer, your eyes have probably gone bad reading the fine print in your dog-eared copy — Louis E. Frenzel November 3, 2005 Polar Modulation Emerges Unless you design EDGE or 3G/UMTS cell phone handsets, you may not have heard of polar modulation. As you know, there are only a few basic types of modulation, but they have been used in a variety of combinations over the years. This one is unique and may actually show up a great deal in the newer 3G handsets... — Louis E. Frenzel October 3, 2005 Wireless Overkill And My Cell Phone Wish List The Cellular Telecommunications and Internet Association (CTIA) met last week (September 27-29) in San Francisco to discuss the state of the industry and figure out what is next. This is the big meeting held twice a year for the cell phone carriers, manufacturers, and others that serve this huge industry. I should have gone this year but I didn’t because of other conflicts. It is one of the more interesting meetings of its type as it sets the tone and direction for this enormous industry... — Louis E. Frenzel March 2005 Make Way For WiMAX Certified Products This year, the market will welcome the first wave of broadband-wireless products that were built to comply with the Worldwide Interoperability for Microwave Access (WiMAX) IEEE 802.16-2004 standard. WiMAX was developed to support the compatibility and interoperability of broadband-wireless-access (BWA) equipment. It supports many wireless-broadband connections including the following: high-bandwidth metropolitan-area networks (MANs) for home and small-business users, backhaul networks for... — George Wu March 2005 Interface Technology Must Match New Data Services In today's wireless industry, operators are facing declining voice revenues. As a result, they're actively seeking compelling data services to maintain and/or increase the Average Revenue Per User (ARPU). The devices that contribute to data-services revenue are being heavily pushed by operators. Examples include camera phones for MMS and phones with QWERTY keyboards for e-mail. This emphasis on data services has led to the rapid introduction of devices that are optimized for such... — Bill Loller February 2005 Microwave Absorbers Help Wi-Fi Perform Wi-Fi is truly ushering in a communications revolution. This technology is the first of its kind in an age when thousands of people are unplugging their phone jacks. Now, the wireless Internet is beginning to fully encompass the globe without phone lines and buried cable. During the past year, manufacturers of materials that control electromagnetic interference have been providing supporting technology to the network-infrastructure companies that manufacture indoor/outdoor Wi-Fi switches. ... — James Delprete February 2005 Can Access And Privacy Survive Next-Generation Systems? The mechanistic world view, taking the play of physical particles as ultimate reality, found its expression in a civilization which glorifies physical technology that has led eventually to the catastrophes of our time. Possibly the model of the world as a great organization can help to reinforce the sense of reverence for the living which we have almost lost in the last sanguinary decades of human history.—Ludwig von Bertalanffy At first, access and privacy seem to be... — Ryan Olson January 2005 Public Safety Overcomes Communication Issues Without question, there is an ongoing and critical need to improve the mobile wireless communications infrastructure that's used by first responders and public-safety agencies across the U.S. In fact, certain problems have acted as key barriers to effective first-responder and public-safety communications and operations. Specifically, these problems include security limitations, communication interoperability challenges, and the availability—or lack thereof—of adequate bandwidth... — Edward Swallow , et al. January 2005 Technologies Look To Bring Backup Power Out Of Flux Across the wireless industry, a confluence of factors has made the upgrade of backup power a top priority. Networks are straining to handle the burgeoning number of products and the skyrocketing demand for them. At the same time, networks must provide the reliability that consumers expect. In 2003, the blackouts on the East Coast of the U.S. revealed the extent of this pressure. Not surprisingly, carriers are striving to optimize every aspect of their networks including backup power. The... — Eoin Connolly  prev. page
