(September 2007) I wrote this for
Messaging Manager and include it here with permission from
Dell as a sample of my work. These high-quality guides were sent with evaluation
systems to product reviewers and helped earn numerous Editor's Choice awards, such as
this one from PC
(January 2007) This technical paper describes Dell's hybrid H2Ceramic
cooling system, which is used in high-end Dell XPS gaming systems.
This Wikipedia article
was written to make it easier for people to find information about H2C
and the Peltier effect, and to link to the technical paper and a 17-minute video
from one of the inventors.
Home Technology Integration: A Technology Forecast(market research)
Prepared for the Texas State Leadership Consortium for Curriculum Development in
conjunction with Technology Futures, Inc. Examines HTI trends and concludes that
community and technical colleges are ideally suited to offer home technology
integration training and that curriculum should be structured around local
industry advisory committee recommendations and the industry approved CompTIA
HTI+ certification. Students should be expected to complete this important
certification upon graduation.
(December 2004). This paper contrasts the different incentives of
incumbent ISPs, municipalities and other stakeholders, suggesting that the cost of extending fiber
closer to premises is high enough to cause IPSs to cherry pick the most
profitable customers, leaving others to fend for
themselves. That’s where public broadband comes in, but the politics can pose obstacles for municipalities that want their own networks, so
this paper also includes a section explaining the fears of various stakeholders.
Incumbent phone companies, for example, fear competition from
VoIP alternatives and are using their deep pockets and
powerful lobbyists to delay competition as long as they can.
Wireless and Bandwidth for TeleWork(1/4-size PDF
(November 2004) at the Austin InnoTech Conference and Expo in conjunction with the CIO Summit. While Austin fights over toll roads and light rail, other
high-growth regions are driving economic development with TeleWork programs and
high-speed fiber and wireless networks. They know technology innovation depends
on sharing knowledge, and telecommunications infrastructure is just as vital to
future economic growth as transportations systems were in the past, where
companies, industries and cities benefited by being near highways, waterways,
railroads and airports. Speaker Notes are also available.
Home & Building Automation & Control(1/4-size PDF
presentation slides, 8.5MB)
(January 2006) This presentation to the IEEE Computer Society examines new and
disruptive developments in the technologies used in homes, commercial buildings,
and manufacturing lines to control lighting, HVAC, security, entertainment,
appliances, and other devices. It summarizes a market research report written
for Parks Associates (described below) that also examines market drivers and
remaining challenges while providing forecasts, company profiles, and
descriptions of each of the enabling standards.
(September 2004). The home controls industry is poised to cross a
30-year-old chasm separating high-end new homes from much bigger opportunities
in mainstream retrofit markets. Caswell was contributing editor with Tricia
Parks of Parks Associates.

The emerging wireless technologies discussed in this
report will have a compounding effect that greatly extends the reach of wireless
networks and improves performance by as much as 10,000 times the speed of
dial-up 56 Kbps modems.

Opening plenary presentation from POF2003 (The 12th International Conference on
Polymer Optical Fiber) at the University of Washington in Seattle, presented as
the opening plenary for over 100 attendees from 14 countries.

I recently went to Fry’s to buy more wireless LAN equipment for my home office. With nearly 100 SKUs to choose from, representing each version of the IEEE 802.11 standard known as Wi-Fi, I wondered how consumers might ever make sense of it all. While I pondered my purchase, I overheard two college kids ask a sales
associate to for help. The sales rep offered some advice, but it was clear that his knowledge was limited, so I introduced myself as a wireless consultant and answered some of their basic questions. Our casual discussion evolved into a 20-minute WLAN course that attracted about a dozen onlookers who also bought
wireless products. The father of one young man thanked me for condensing so much information into such a timeframe, and that fun experience convinced me to write this article and explain the tradeoffs that can help you make your own WLAN decisions. (contains a useful comparison grid)

Debate still lingers over government’s role in building an Information Superhighway and whether our lack of a national broadband policy means the concept is forgotten. Broadband – the “always on” network connection that receives and transmits digital content and services at high speeds – was supposed to change
the way we live, work and play … as well as how we learn, shop, make things, entertain ourselves, and interact with others. It was supposed to give us remote access to libraries, museums, medical care, jobs, and government – resources that are available only to people living nearby. But since that aging
vision is coming slower than expected, this paper aims to revive the initiative.
(March 2003). I attended CES to follow the wireless industry and wrote this event report as an extension of a speech I gave to the International Wireless Packaging Consortium the week after the show. CES attendance broke all previous records in the face of last year's economic recession, and the show
attracted more than 2,200 exhibitors and over 100,000 attendees. It was clear that all sorts of wireless markets remain hot -- from Wi-Fi and Bluetooth, to mobile phones, satellite radio, GPS navigation, and more. All of this activity benefits consumers by driving down prices, improving performance, and adding
function. Wireless PC adapters now sell for less than $50, and wireless routers sell for less than $100. Even with confusion among the competing standards, it's a good time to buy.
(August 2002). Applications determine bandwidth needs and costs.Health monitoring, for example, requires very little bandwidth but saves lives and has high value.If your applications only need to send text and data, then dial-up modems can
provide enough bandwidth for your needs, and they cost less than broadband.The Internet experience is enriched by added graphics, images, sounds and video, but this requires more bandwidth.
(June 2002). Innovative semiconductor companies are introducing software-defined radios for wireless LANs this year, and we already see examples of multi-mode in mobile phones and enterprise wireless access points.I expect to see multi-mode PC adapters in 2002 that help move the
industry away from the confusing Wireless Wars to a more cordial Wireless Wedding.Consumers and industry will both benefit from this new direction.
Some of the products discussed provide adequate performance under ideal conditions, but there are many things that emit radio interference that can impact performance. These include stadium lights, cordless phones, microwave ovens, wireless LANs, and anything else that operates in the unlicensed 900 MHz or 2.4 GHz
frequency band. For surveillance and most music applications, the impact is often acceptable, but for more demanding audio and home theater applications, you would be better off buying more advanced technology based on the proprietary technology from Cirrus Logic or the open HomeRF specification.
If there’s a Wireless Home Networking lesson to learn from the Tower of Babel, it’s that we don’t need (and will never have) one wireless standard for homes, offices, schools, airports, restaurants, grocery stores, bowling alleys, and beauty shops. As intriguing as it may sound, it is not practical or desirable to have
one wireless standard for all environments, purposes, and types of devices.
Because HomeRF supports up to eight toll-quality voice lines simultaneously, broadband carriers can allow each family member to have his or her own number and remotely provision new phone numbers and services. Rather than being limited to just two phone lines, broadband customers with
HomeRF will be able to activate additional lines as younger kids grow up, when older kids come home from college, or when visiting guests arrive, even transferring their own number.
(Network World Face-off,
Although originally designed for home networks, HomeRF is the best choice for teleworkers because working from home or on the road introduces network requirements that enterprise wireless LANs still can't address. IEEE 802.11 variants, such as Wireless Fidelity (Wi-Fi), fail to provide
toll-quality voice services and compare poorly in such aspects as power consumption, reliability and support for high-network-density environments such as apartment buildings.
In this last of a three-part series, I will explore some of the Social and Demographic trends that are driving the development of the Networked Home. The first article covered Science and Technology Trends, and the
second focused on Market and Consumer Trends. As always, your comments and suggestions are encouraged.
This is the second of three articles that examine key trends enabling and driving the development of the Networked Home. The first article covered Science and Technology Trends while this one discusses Market and
Consumer Trends. The final installment will address Social and Demographic Trends. As always, your comments and suggestions are encouraged.
What is driving and enabling the Networked Home? This question is common among homebuyers who don’t want their new home to become obsolete before they sell and move out (or even before they move in). Builders also ask it, since they don’t want to add new features until customers demand
them. And companies that make the products, services, and technologies want to understand the market opportunities, leverage points, alliances and risks. Although the question is simple enough to ask, the answer can be complex, since it is surrounded by a collection of market, economy and technology trends.
With powerline networking, you’ll be able to put your desktop PCs anywhere you like instead of being forced to put them by a phone outlet. It will also be easier to buy and network other devices – printers, scanners, DSL and cable modems, TV set-top boxes, game consoles, screen phones and major appliances.
The vision is for Internet access by anyone, anytime, anywhere, and on any device - truly pervasive Net access - and the report covers a wide variety of information appliances and their means of connecting. After providing an overview with descriptions of the market segments, overall
benefits, and macro-level drivers and opportunities; this report provides detailed descriptions of each segment, along with the specific drivers, opportunities, and major players. Three chapters then focus specifically on the enabling hardware, software, and networking technologies that serve these markets.
The last chapter of this 340-page report offers detailed forecasts.
The cost of connecting PCs with radio waves instead of wires is now as low as $99 per system, and there are several technologies to choose from. But that's the problem - too many to choose from. Since a confused market doesn't buy, I'm dedicating this second HomeToys.com "mentor" article to
positioning the three emerging wireless standards - Bluetooth, IEEE 802.11b, and HomeRF.
New types of devices have helped to change the thinking of home networking experts. Six years ago they said to put bedroom phone outlets by the bed and TV outlets across the room. But they didn't anticipate interactive program guides or NetTV devices that require both a phone and TV outlet.
So today they put a phone outlet by every TV outlet. Still, no one can fully anticipate future wiring needs, and that's the message of this article.
The Home Radio Frequency Working Group has a vision - to enable the communication and sharing of voice and data from anywhere in and around the home without wires and using a variety of interoperable devices -- PCs, peripherals, cordless telephones, and other consumer
This special feature focuses on the HomeRF Group and the Shared Wireless access Protocol, which is partly based upon DECT technology. This feature has been kindly contributed by Wayne Caswell of IBM Microelectronics.
HomeRF is working to provide the foundation on which a broad range of consumer electronic devices can interact through digital wireless technology. The Shared Wireless Access Protocol (SWAP) provides member companies with that foundation. The products that member companies will eventually
provide will offer consumers a user experience unlike any other. Consumers no longer have to be "tied down" to a modem connection or an electrical or phone outlet. They will be free to move about and still use their PC effectively.
The paper predicted trouble for the telecommunications industry because of a pending glut in available bandwidth. This glut will be caused the deployment of more optical fibers, plus the use of WDM to support more colors per fiber, plus semiconductor advances that enable lasers that pulse faster.
Digital Convergence in the Home
(Microelectronics Design, February 1998).
The difference between TVs, computers, phones and other digital devices is becoming irrelevant. In the past, separate forms of information content (text, sounds, pictures, and video) were sent over special-purpose networks and accessed by dedicated devices. Once digitized into bits, however, this content
can be combined and sent across diverse networks, and manipulated by a variety of devices. Convergence gives consumers more value and a choice of network and access devices. It also affects the way they use technology and even fuels economic and social change. But, in the process, convergence
commoditizes consumer products and increases competition. And this puts additional pressure on manufacturers, who need to keep adding new technologies while also becoming more agile and efficient. The development of networked, digital devices with competitive price, function, and flexibility is a

(1995 white paper). This document focuses on specific OS/2 Warp features that apply to PC gaming. It assumes that the reader is already familiar with OS/2 as a PC operating system. The first section, "OS/2 Warp for PC Gamers," describes OS/2 as a games platform, solving many of the problems PC users face when playing games under DOS or
Windows, and helping to usher in a new breed of high-performance 32-bit games. It was published in IBM Personal Software Technical Newsletter, Issue 1, 1995. The second section, "OS/2 Warp for PC Game Developers," describes unique advantages OS/2 has as a development platform and contains detailed information
for program developers. It was published in the May/June 1995 issue of IBM Personal Systems Technical Solutions magazine.

At Home with OS/2: a Telecommuting Update and Outlook
(1994 white paper).
This paper discusses IBM's OS/2 as the preferred platform for telecommuters (with its strong client/server benefits) and for home computing (with the new Personal OS/2, designed specifically for home and mobile users). The first section gives a high-level view of telecommuting growth and
benefits, along with examples from IBM's internal TC experiences and with recommendations for establishing similar programs. Next, is a discussion of the home computing markets and OS/2's current benefits there, its challenges, and IBM's plans for it.

Personal Software Technical Newsletter, 1993).
This paper shows PC users how IBM technologies can be applied to home computing applications and how OS/2 provides unique benefits as a PC operating system for the home. There is still much work to be done to make OS/2 (and personal computers in general) more of a consumer product, like the telephone or TV or VCR.
Almost every household in America has a phone and TV. Many have several. Computer technology, however, is still too new, lacks compelling applications, and is too difficult to use for many consumers to be interested. That's the current view, but OS/2 is helping to change that view.
