Broadband Lifestyle Interfaces – Energy Management

With more than 80 million households in the United States potentially able to connect to an always-on broadband infrastructure, there is substantial potential for operators to deliver innovative new services to the home. For instance, a service that enables a residential consumer to more effectively manage their energy consumption may be offered without the prerequisite of a high-speed Internet service subscription. This “Broadband without Internet” service model is well suited to telemetry and control applications, which rely on a persistent broadband connection, but do not require high speed or the other features associated with the Internet, such as e-mail. These types of services are developed to provide benefits to consumer with little or no cost while also providing value to the service provider, in this case the electric utility.

An energy management service interconnected via broadband communications can provide a method of controlling demand during critical consumption periods as an alternative to additional energy generation. This form of capacity will provide benefits to both the utility and consumer. As a result, services such as these can potentially make the existence of a broadband connection in the home as essential as electricity or the telephone.

Description of an Energy Management Service

Energy management equipment allows the homeowner and electric utility to monitor and control the appliances that are responsible for the majority of the electric load in the home, e.g., air conditioning, water heaters, pool pumps, etc. With a persistent connection provided to these devices as well as the house electric meter, energy demand can be monitored almost real-time. The homeowner can also use this capability to automate their comfort control systems and other high load appliances. Additionally, the homeowner has access to the system through equipment interfaces in the home and also remotely via the Internet, where detailed reports specific to that home can be viewed. The utility can also use a secure web based interface to utilize these same capabilities at an aggregate level, within a single location and over many locations, to curtail consumption within the guidelines of the customer service agreement.

Roles and Benefits

Consumer Benefits

Participation in a demand-side management program allows a consumer to have greater control over their comfort systems and high-energy consumption devices. Because the service is provided over a broadband connection, the homeowner has access to instantaneous data, both within and outside the home. Additionally, it is possible for the homeowner to decline to participate in a given curtailment. Benefits of participation in the service include:

  • More intelligent use of energy, resulting in potential savings
  • Remote access to comfort controls and remote monitoring of home environment
  • Energy conservation, and concomitant reduction in pollution and consumption of natural resources
  • Ability to schedule comfort settings to correspond with home occupancy patterns
  • Ability to schedule run-time cycles on pool pumps and water heaters to correspond with needs
  • Ability to monitor energy usage and expense between billing cycles
  • Analysis of an individual home’s energy efficiency and performance by monitoring temperature ramp and recovery rates of heating and air-conditioning systems

By allowing the homeowner to opt in to specific curtailment programs, the user application permits a homeowner to tailor the extent of their participation in demand-side management to their unique needs and comfort scale. In addition, homeowners may opt out of specific curtailments by canceling them once they have taken effect. Of course, a homeowner’s cost savings or other incentive would vary depending on their chosen level of participation.

Utility Benefits

Electric utilities are responsible for generation, transmission and distribution of energy to their customers. Their infrastructure must be capable of supporting peak demand, e.g. supplying power for air conditioning on a hot August afternoon. Regionally, homes have consumption patterns that typically peak during a specific portion of the day. These peaks may shift seasonally. The summation of these peaks requires a grid capable of far more capacity than the average consumption requires. For example, during warm days in the summer, power grids and generators may be operating at or near maximum capacity during the afternoon peak cooling period. Generation to support this peak demand may require the construction of additional power capacity, the use of more costly “peaker” power plants, or spot purchases of energy from intrastate transmission companies, often at very high prices.

Demand-side energy management systems assist in reducing demand for energy at these peak times. Through the monitoring and control capabilities contained in the installed hardware and associated software, curtailments can be issued to reduce peak consumption, reducing the difference between peak and average demand. Often, curtailments cause load-shifting patterns, where the peak load is shifted to a below average usage period later in the day. This results in greater efficiency for the utility and reduced strain on generation assets. The goal is to turn the sharp, peak demand consumed in a few short hours of the day into a level, sustainable consumption throughout the day.

Curtailments can be issued through a combination of events: by temporarily shutting off discretionary loads such as hot water heaters and pool pumps and/or by making changes to the environmental thermostat control set points. The system is designed to change a homeowner’s thermostat setting in small and gradual increments to minimize the perception and impact of the curtailment. In summary, the utility can use an energy management service as an alternative to activating costly “peaking” power plants or to the purchase of expensive spot market power from other plants. Potentially the stress on local transmission and distribution facilities may be reduced through monitoring and targeted curtailments.

Broadband Service Provider Benefits

The broadband access provider is responsible for providing a secure and managed network connection to the home. The energy management service may be delivered to the home without requiring the homeowner to subscribe to high-speed data services. Therefore, the service provider gains the ability to provide a broadband service to a home independent of the homeowner’s choice to subscribe to any direct product offerings. This represents a new revenue opportunity and does not relate to or interfere with the ability to sell traditional products, such as high-speed Internet.

Components of Demand-Side Management

Communicating devices --> Click for larger pictureThe system as currently implemented consists of an energy gateway, one or more communicating thermostats, and optional subnet metering switch modules. The energy gateway is comprised of a DOCSIS cable modem integrated to a gateway. The modem is configured specifically for the data associated with the energy management service. The gateway contains an embedded processor and control applications and the radio components necessary to communicate with the metering and control devices. The communicating thermostat is similar to a conventional programmable thermostat, but with the capability to transmit and receive temperature, heater or air-conditioner mode, and set points data and commands to and from the gateway.

Invensys RF Load Control Meter --> Click for larger pictureThe solution also includes a meter and switch device called an LCM (Load Control Meter) that may be installed in any home branch circuit to create a separately controlled and metered subnet. The LCM allows control of dedicated high-current loads such as electric hot water heaters, pool and spa pumps.

Invensys communicating electrical meter --> Click for larger pictureA communicating electric meter is included, allowing monitoring of whole house consumption and remote meter reading, which may provide an additional benefit to a utility not currently implementing such a capability.

All in-home elements can be installed by the energy management service provider, including the broadband access gateway.

The infrastructure components in the system include a data aggregation server, security server and web-based application server. The radio communications protocol has been optimized for range and reliability at a low data rate.

Trial Activities

Comcast New Media Development and its partners, PECO Energy Company and Invensys have been conducting a technical trial of a demand side management product, “GoodWatts(TM)”, since the summer of 2002 in Southeastern Pennsylvania. Approximately 100 homes were outfitted with the system for the purposes of technical evaluation and to begin measurement of the effects and impacts of demand-side management. Invensys developed the communicating hardware and application software and additionally manages the energy data, providing it to both the utility and homeowner.

Trial participants have reported favorable experiences, and have liked the benefits of conservation, and remote access to their comfort control systems. Curtailment events during the trial have successfully reduced consumption in the homes and are a preliminary indicator of the efficacy of demand-side management. Network traffic going between the homes and infrastructure servers has been measured and determined to be small enough to allow large scale deployments without impacting high-speed data users. Efforts are underway to secure a larger scale market trial in order to more fully quantify the impacts of demand-side energy management.

Future Opportunities

The introduction of broadband monitoring and control capabilities into the home may allow for the future extension of other benefits to the homeowner. The ability to remotely provision software into the embedded processing gateway allows additional applications to be easily installed. In the future, new and existing appliances will be provisioned with integrated communication capabilities that enable additional applications for automation and remote monitoring services such as breakdown detection, lighting, appliance timing, and home security and safety applications.


A demand-side energy management product is a tool for both the electric utility and homeowner that provides for flexible control of power consumption. Use of a secure and managed broadband connection adds the ability to verify the effects in real-time and benefits the broadband service provider by increasing their service reach to homes, beyond traditional products. As a result, the electric utility gains operational efficiency, the customer benefits from greater control and potential for conservation, and the broadband service provider obtains new service revenue.

Broadband Wireless World - The "Big Boys" Have Arrived

Attending a conference for the first time, we try to form a composite of the show's target industry or group. Aside from the obvious connection that the attendees were interested in wireless broadband technologies and services, those we met at last month's Broadband Wireless World represented tremendous diversity, including:

  • Companies large (Verizon and Intel) and small
  • Using licensed and unlicensed spectrum
  • Using proprietary technologies and those based on standards such as 802.11/Wi-Fi, 802.16/WiMAX, 802.20, and (surprisingly) DOCSIS
  • Established local exchange companies and new competitive providers
  • Targeting urban, suburban and rural markets

We concluded that part of the diversity comes from the fact that broadband wireless technologies make sense for many different market segments. Much of the WISP activity has been in "unserved" markets: areas with low population densities that did not receive broadband service from either the local telephone company or the cable operator. Now wireline carriers are evaluating broadband wireless to reach homes within served markets but not reachable by current technologies -- such as homes more than three miles from the telephone central office. It is increasingly being deployed to compete with existing wireline broadband services.

We are also starting to see a market transition from an opportunity which had first drawn the attention of small entrepreneurial groups that founded WISPs, but now is garnering more big company and mainstream attention. Verizon is clearly in the latter category.

Verizon--"Technological Diversity in the Physical Plant"

Brian Whitton of Verizon --> Click for larger pictureWe have written previously about broadband wireless trials by both Verizon and BellSouth. A keynote speech by Brian Whitton, Executive Director of Network Platform Evolution at Verizon, described how Verizon believes in technological diversity in the physical plant, using technologies that are "service agnostic and service unaware." He said that Verizon can currently qualify between 60-65% of customers from the CO to receive DSL service. That leaves 35-40% that either won't be covered or need another technology to do so. Verizon sees "broadband fixed wireless" (BFW) as one means to increase coverage of DSL-like services. Brian is also very much involved in fiber planning and deployments and this is another direction we expect to see Verizon pursue--although its planning and deployment are significantly slower and more costly than BFW.

Because of recent BFW technology advancements like non-line of sight and self-install, Verizon trialed BFW to see if it could handle the rate, reach and service transparency they required. Brian reported that the trial service did indeed provide the required service coverage of 90%, 99.9% of the time and with sustained DSL-like transmission rates of between 768 kbps and 1.5 Mbps.

Now that Verizon's Fairfax trial has been completed with successful results, they are evaluating RFP responses and expect to select a vendor this quarter; commercial deployment is planned later this year. This depends, however, upon vendor responses meeting Verizon's business case constraints, which include not only price and performance but also OSS integration, tower availability, affordability and access.

It will be interesting to observe where Verizon chooses to deploy BFW (assuming they go forward with it) and where they deploy with fiber. A recent key FCC decision will allow ILECs like Verizon to deploy fiber without requirements for sharing with competitors. Verizon and other LECs have already announced their intention to move more aggressively to use fiber to accelerate DSL deployments, in some cases using existing fiber to deploy DSL from remote terminals, in others to deploy new fiber. We see a balancing act between time to deploy and cost on one hand (favoring BFW and other DSL extension methods) and the desire to offer the complete triple play of services (favoring new fiber). So we'll be watching to see what happens with the RFP selection later this quarter.

Intel--Wireless is More than Wi-Fi

Sriram's positioning of segments --> Click for larger pictureWith the huge public focus that Intel has been putting on Wi-Fi, we were delighted to hear Intel present a balanced view of broadband wireless (see the following article). Sriram Viswanathan, Managing Director at Intel Capital, presented a talk that posited that Wi-Fi is the current wireless disruption and that 802.16 might be the next. He divided broadband wireless access into three basic segments: fixed (for residential and SMB access and for backhaul); portable (destination based and ad-hoc); and mobile.

In the metropolitan area network (MAN) portion, Intel is very supportive of the 802.16a standard, because of its higher throughput at longer ranges and quality of service support. Sriram's talk included a chart showing comparative performance, measured as maximum bits per second per Hertz: 802.16a is capable of ~5 bps/Hz, 802.11a at ~2.7 and 802.20 projected at ~1. Intel has become an advocate for the WiMAX Forum as a way to accelerate broadband wireless access deployments worldwide. Sriram sees WiMAX as the organizational equivalent of the Wi-Fi Alliance for 802.11: driving interoperability and compatibility of IEEE 802.16 conformant systems, leading to interoperable equipment and a stable, standards-based platform.

For component makers like Intel, this represents a volume silicon opportunity. No wonder then that his summary slide said "802.11 is the driver for the 2nd coming of Broadband Wireless."

Our Talks

We gave two talks at the conference:

  • In a session on "Profitability for WISPs", our presentation "Making Residential Broadband Profitable -- The Challenge For WISPs" said that unserved markets are shrinking fast as incumbent wireline providers fill in the gaps, and that WISPs will need to develop competitive strategies based on wireless advantages.
  • We ran an hour-long "Ask the Experts" session. Our presentation "Broadband Applications Trends and Evolution" discussed current and emerging broadband applications in the home. We showed our "home movie" about how we use broadband in our own home, and answered questions from the audience on audio and video applications.

Broadcom - Today the Laptop, Tomorrow the TV?

With all the buzz about Wi-Fi and wireless networking, it's easy to get swept up in the excitement. It's certainly been true that this has been one of the few bright spots in an otherwise depressing and depressed telecommunications environment. Semiconductor companies are the starting points for the products and services of tomorrow and so it's always interesting to understand where they are placing their resources and their rationale for doing so.

Broadcom is one of the leading players in chips for broadband access and networking. Their chips go into cable and DSL modems, digital cable and satellite set-top boxes, home gateways, and many types of home networks including Ethernet and Wi-Fi. We visited with Broadcom to discuss wireless networking in general and 802.11g in particular. We met with Jeff Thermond, VP and GM, Home and Wireless Networking Business Unit, and with Jeff Abramowitz, Senior Director of Marketing.

802.11g and "54g"

As many readers know, 802.11g is the latest version of the IEEE 802.11 standard, providing up to 54 Mbps at 2.4 Ghz. 11g products are fully back-compatible with the very popular 802.11b "Wi-Fi" products, and can operate together in mixed networks. The earlier 802.11a standard provides the same speed as 11g, but is not compatible with 11b, since 11b and 11a operate in different spectrum (2.4 GHz and 5 GHz, respectively). We believe that 11b will fade out in favor of 11g and dual-band 11g/11a systems.

802.11g is not yet an approved standard--final standards approval is expected in the next few months. We expect the Wi-Fi Alliance to start certifying 11g products and applying the "Wi-Fi" logo shortly after the standard is ratified.

Broadcom decided not to wait for the standards process to be completed, and released a pre-standards silicon solution into the market late last year with the name "54g™". Many companies have now brought 54g-based products to market. These include home networking products--routers, access points and LAN cards--from Linksys, Apple, Belkin and Buffalo; and notebook PCs from Compaq/HP and soon from Dell.

54g wireless access point and broadband router --> Click for larger pictureBroadcom's aggressive strategy appears to be paying off. In March it announced that it had shipped more than three million 54g chips since starting production in December 2002, and Linksys--the leading provider of wireless LAN products--reported that its sales of 54g products approached 802.11b sales in February.

This strategy is not without risks. Broadcom has said that its "54g" solution has enough built-in flexibility that pre-standard products can be upgraded to the final standard with a firmware download, and Thermond and Avramowitz are still confident of this. But this claim won't be proven until the standard is ratified and full interoperability testing is completed. Of Broadcom's 54g customers, only Buffalo explicitly assures buyers that "if the certification materially changes the principal operating features of our pre-standard 802.11g products, we will replace or upgrade any of those products at no charge."

Next Steps for Wireless

Jeff Thermond believes that "dual-band tri-mode" products--supporting all three standards--will eventually dominate the market. These mature products will include the full QoS and security standards--being developed by the IEEE 802.11e and 802.11i working groups--which are now expected to be completed in early 2004.

Pending completion of these standards, the Wi-Fi Alliance has released an interim security specification called WPA (a subset of the draft 11i standard) and will probably do the same for QoS. Existing 54g-based products should be upgradable to these interim specifications with a new firmware download--Broadcom reference designs were among the first products to receive Wi-Fi certification for WPA. Thermond believes that the chip has sufficient processing power to handle the requirements for the full specifications.

The 54g strategy is just the start of Broadcom's plan to position itself as one of the long-term leaders in the wireless business. Broadcom believes that wireless networking will be embedded into many products -- from home gateways and game players to portable phones and TV sets.

Thermond said that Broadcom's strengths lie in integrating many functions together to create systems on a chip, and that 11g and eventually 11g/11a will become a core component in single-chip designs for low-cost consumer devices. He predicts that as the market shifts from networking devices to consumer products, Broadcom will be one of the winners with low-cost fully-integrated silicon solutions.

We have recently received networking products based on Broadcom's 54g chips from Linksys and Buffalo, and are testing them as part of our comprehensive 802.11 home networking test. We hope to report on these devices in the next issue of our report.

Wi-Fi Press: Sense or Nonsense?

The drum beat of reports about the glories of Wi-Fi have increased to such intensity that a backlash was inevitable. Contrary to rumor, Wi-Fi does not cure male pattern baldness nor make teleportation possible. One reader shared a link that expressed the growing weariness with the hype. See to find out about "WiFi Speed Spray", but be sure to bring your sense of humor.

Don't misunderstand our waggish humor here--we are confirmed Wi-Fi users and believe the technology is really wonderful for "cutting the cord". After all, it's what makes possible the Smart Display we've been using and write about elsewhere in this issue. It's just that some of the stated claims for "Wi-Fi" have gotten pretty overblown.

We recently read two articles that helped to put Wi-Fi in perspective. The first, by Tom Nolle in Network Magazine ( ), asks if 802.11 could displace DSL or cable, and concludes it's "more likely that it would augment the two."

The second, by Robert Wells, Managing Director at Lennox Research ( ), analyzes 15 articles from the recent press. It charts "the pundits predictions about Wi-Fi's Future" and shows how they fall all over the map--both about Wi-Fi's potential for profit and its level of disruptiveness as a technology. Wells thus concludes "they definitely can't all be right".

We believe much of this disparity is the result of people using the term "Wi-Fi" very loosely. When they write (or say) "Wi-Fi", some really mean "broadband wireless". Too many writers can't (or don't bother to) distinguish between real Wi-Fi as defined and trademarked by the Wi-Fi Alliance; technologies based on modifications to the 802.11b standard that make them ineligible for interoperability certification; proprietary broadband WMAN technologies; and the coming 802.16 or 802.20 WMAN standards.

Viewed this way, we see justification for categorizing the "broadband anywhere" technologies (which 802.20 aspires to) in the "upper right" of Wells' chart--they are both highly disruptive and have the potential for big profits. If you substitute "wireless broadband" for "Wi-Fi", it would also help understand reports like this one from USA Today on April 17th: "By using Wi-Fi, parts of Iraq could skip the build-out of traditional phone and cable networks altogether."

Is there a phrase that means "wireless broadband" independent of what it's used for, including both WLAN and WMAN, fixed, portable and mobile? Perhaps what we really need is to invent a brief phrase everyone can use for easy reference. How about "WiBro" or "Wi-Broad"? If you have a better idea, or think there's already a short phrase that captures the generic meaning, let us know. We'll print your comments next month and see if its use will grow.

Broadband Home Labs - Our First "Smart Display"

We first saw a Webpad more than three years ago, and have long believed that these wireless touchscreen devices would play an important role in the broadband home. Now we're testing a ViewSonic airPanel V110 - one of the wireless networking devices based on Microsoft's "Windows-powered Smart Display" technology. Here are our first impressions based on using it for a few days.

The airPanel V110 has a 10" LCD screen with a resolution of 800x600. It has built-in 802.11b wireless networking and works fine with an existing Wi-Fi access point in our home network. For input, it uses a touchscreen with a stylus and also has a "mouse-like" mechanism. It does not have a keyboard--text input is done on an on-screen keyboard and with a handwriting recognition system. It is sold with an optional dock to charge the battery and attach keyboards and/or a mouse.

Smart Displays are not intended to be stand-alone client devices. Instead, they are an extension of the screen of an existing Windows XP Pro PC - they "enable a user to pick up the screen and have the same PC experience in any room" as we said in our article on Smart Displays in BBHR 11/24/2002 .

V110 Smart Display in our kitchen --> Click for larger pictureWe have been using the V110 for three days so far, and have been very impressed with it. It has done nearly everything we expected and some things we didn't think it could do:

  • It's a great extension of the "always on" experience - now we don't have to walk to a PC to get on the Web. We've used it to surf the Web in the kitchen while watching TV and in other places in our house while away from our PCs.
  • We've used it to play music throughout the house from our AudioTron digital audio player and on a headset from Rhapsody.
  • We've used the handwriting input mechanism to make notes.
  • We set it up so we can connect to either of our main PCs.
  • The battery life is good and it works well with our wireless network.

At SCTE Cable-Tec Expo we also had a preview of the V110 running the Nevo home control software from Universal Electronics. With this software, the Smart Display transforms itself into your personal universal remote control. Unlike all the other applications we've used, the Nevo software runs locally on the V110 rather than remotely on the master XP Pro PC. It provides a good example of additional types of applications that will provide value, beyond extending your desktop applications around the home. Nevo will be available in July and is currently free when users buy a ViewSonic display.

Our biggest issue is that a person can be logged into a PC from only one place, either from the PC's main screen or from the Smart Display; logging in on the Smart Display logs off the main screen. This isn't a huge problem for us, since we each have our own PC, but it would be a real problem in a home with only one main PC. Microsoft has just announced that they will be addressing this problem in the fall with a new Windows XP mechanism permitting two users to be logged on simultaneously.

The other real-world issue in buying one of these devices has been the price. The V110 unit we are trialing had been selling for around $1000. However, is listing the product for $799 with a $75 rebate. If this means a newer unit is on its way, it will be interesting to watch the pricing of the next units. Nice as the V110 seems, our personal willingness to pay, and we suspect that of other consumers, is well below the $1000 price point.

Net-net, our initial impression is that this device is well "over the bar"--it works well and its human factors are surprisingly good. We'll provide a full report in the next issue.

Lifestyle Notes from the "Always-On" World

With all the discussion about broadband's increasing speeds and applications, it's easy to take for granted the life-style changes that an always-on service makes. It's hard to figure out when our behavior changed, but it was well over a year ago that we made the Web our reference point for virtually everything. Search tools like Google and the Web's vast resources, plus an always on connection, made it a "no-brainer".

Heuchera "Snow Angel" --> Click for larger pictureA sampling from this past weekend included: finding a great way to whiten a yellowed synthetic blouse (, planting tips for a new Heuchera Snow Angel for the garden (, and an on-line audiology test (

In each case, "always-on" was more important than broadband speed; what made it useful was the fact that we could access the Web immediately and find the answer. Now "always-there" devices like Microsoft's Smart Display (see the article elsewhere in this issue) help users take the next step and have the information right at hand, helping to reinforce the behavior.

The problem for service providers is that there's virtually no way to get this across to anyone who isn't experiencing it. It's exactly the same problem that PVR companies like TiVo have. Anyone who has it can't live without it and won't give it up; anyone who doesn't, can't understand what all the fuss is about. But world of mouth and viral spread make it inevitable that both will reach and pass the tipping point--just like voice mail and answering machines did many years ago.

Disruptive Technology in Action

Clayton M. Christensen's book "The Innovators Dilemma" introduced the concept of disruptive technologies and has been a frequent topic in these columns (see BBHR 10/26/2000 ). We're living in a world where every day we see the disruptive effects of IP communications on incumbent companies. For telephone companies, it increasingly means the end of metered telephone service.

Vonage Web ad: "$39.99 - Use your broadband internet connection for great savings every month" --> Click for larger pictureWe've previously written about Vonage providing unlimited calls to anywhere in the US and Canada for a flat fee of $39.99/month for broadband internet users. Now ILECs like SBC are fighting back by introducing an unlimited calling bundle called ALL DISTANCE, which provides unlimited local and long distance calls, plus additional features, for $48.95-$52.95 a month, depending on the state. Verizon has announced a similar plan for small business.

In Europe, we see IP companies like FastWeb bundling flat-rate telephone service to all fixed-line phones in Italy. In Japan, we see Softbank's Yahoo Broadband rapidly adding DSL subscribers and broadband phone users; their VoIP service called "BB Phone" for Yahoo! BB subscribers costs only 7.5 yen per 3 minutes to call from Tokyo to New York, and is free if both sides are using BB Phone. In April they added 184,000 ADSL subs to reach 2,547,000; users of their IP telephone service increased 188,000 from the end of March to a total of 2,162,000. NTT is now responding.

International calls are increasingly impacted by IP. Historically, they have been very expensive, but new services like telcoBlue's Internet Voice Network (IVN) service is using IP to offer savings for broadband users calling Spain, Portugal and Italy from anywhere in the world. Subscribers use a Cisco ATA 186 supplied by telcoBlue which is shipped pre-configured and plugs into an existing cable or DSL modem. This is only one example in a growing area of international IP services.

With telco voice revenue eroding, data has been one potential answer for other sources of revenue. Across the world, DSL dominates broadband service, with cable modems representing less than 40% of all subscribers. US telephone companies' early ambivalence about DSL allowed cable modems to get nearly 2/3 of broadband subscribers. Until recently, those telephone companies--focusing on near-term financial returns rather than market share--were raising the price for DSL services. Now the competitive pressures are finally being felt as ILECs are creating tiered services, cutting prices, increasing speeds and adding differentiated services. In March, SBC with its partner Yahoo! launched a 1.5 Mbps, $35/month service, and offers bundled prices that are even lower; it is said to be planning to introduce a $25 "semi-fast" DSL service in several markets soon. Verizon has also lowered DSL prices dramatically to $35/month ($30 when part of a bundle with other Verizon services) and announced a trial in Manhattan providing free access to Wi-Fi hotspots around New York City.

What's the moral of the story? The hobbyist voice technology that originated with VocalTec is fundamentally altering the traditional telecommunications world. New players and competitors have emerged and the old ones are struggling. Watching it unfold is an amazing process!

Your Voice -- Readers' Comments

Homeland Security Entrepreneurs Wanted

Kelly Porter, Managing Partner of ZAP Ventures, shared with us an article from the April 3, 2003 San Jose Mercury News, focusing on his current search for Homeland Security Entrepreneurs and Investors. ZAPVC was formed as an early stage venture fund with broadband related companies as their core focus. Kelly notes that "Some of the best broadband deals we were seeing in recent months had a homeland security focus."

He indicated that ZAPVC has expanded to include investments “in the growing $100B+ homeland security industry, as a natural evolution of the firm’s charter to invest in broadband-related companies." He added: “In homeland security specifically, we look first at the commercial/private sector potential of a product or technology, and second, at the government market potential. Also, we are generally not talking to either pure biotech companies developing drugs/medical devices (because it is not our expertise), nor companies that are developing weaponry (because of the moral issues involved).”

If you are an entrepreneur who is building a homeland security-related company and who might be seeking investors, check out Kelly’s website for his investment criteria and contact him if there’s a fit.

Powerline as a Third Wire

Oleg Logvinov pointed out that at the CITI PLC III conference, there was a another model presented in addition to the rather pessimistic one we mentioned in our article ( He wrote: "I think it would be fair to mention that Dave Shpigler presented a much more positive model." We agree and readers can see that presentation at .
