DSL Forum Update
The DSL Forum sent a recent update on the status of DSL deployments. A few of the interesting facts:
Becoming Blasé about Broadband
It's easy to lose sight of what an amazing world broadband brings to our doorstep. On June 16 we sat at our PCs and watched streaming video in real time as Jeff Pulver and others testified before the US Senate Commerce Committee on The VOIP Regulatory Freedom Act, S. 2281. You may say: "What's so special about that? I do similar things all the time". That we have started to take this for granted is what's so amazing! ( commerce.senate.gov/hearings/witnesslist.cfm?id=1230 )
Meeting Customer Needs--but which customer?
A recent announcement from video-on-demand equipment provider Concurrent seems like a great example of conflict between the needs of a service provider and what the end user wants. Concurrent's new patent-pending ad insertion technology will prevent VOD customers from fast-forwarding through commercials. Advertisers may be breaking out the champagne, and the service provider gets revenue from the advertisers, but we wonder how happy the end user (who also pays) will be when they find they can't escape the commercials. Concurrent bills the technology as maintaining "Advertisement Integrity" but we think that end users will have other phrases in mind if service providers adopt it. And it will certainly spur the sale of DVRs! ( www.ccur.com )
The next "must have" broadband feature
Whether it's coming soon from BellSouth or BT or a cable operator, it appears that the next "must have" feature in the escalating broadband competition may be (to use BellSouth's name) the "turbo button". Its function? Bandwidth-on-demand. It's good for the customer who can subscribe to and pay for a lower level of service which meets their needs most of the time, but can put their foot on the broadband gas for applications that would struggle with their normal bandwidth. And it's good for the service provider, who charges for the bandwidth boost. Multiple technology vendors are supporting such capabilities. Next, we'll see if customers use it the way service providers expect.
Bigger fish in the pond
Changes in the broadband wireless industry are most evident from who was speaking at the recent Wireless Communications Association International's WCA 2004 conference in early June in Washington, D.C. From the US perspective, speakers included a "who's who" in government, including FCC Chairman Michael Powell, Commissioners Abernathy and Adelstein, Wireless Communications Bureau Chief Muleta, NTIA Administrator Gallagher, plus various legal advisers, technology chiefs, etc. Senior-level speakers came from Australia, Brazil, China, France, Great Britain, Israel, Korea, South Africa and probably other countries we missed.
The smaller companies who have been around broadband wireless for a while--including Alvarion, Aperto, IPWireless, Navini--were there. But so were Alcatel, Intel and Motorola.
Powell spoke supportively about broadband wireless, but also mentioned broadband over power line (BPL) as another potential spur to broadband competition. He said: "I think the continued proliferation of broadband technologies--with wireless playing a critical part--is the key to that solution."
Craig McCaw's keynote started by observing that "every company that has gotten into this space in a broad way has failed". He raised the obvious question of what has gone wrong in the past: "As we're walking over the bodies of our brethren - all of whom have arrows in their backs - we're asking, How can we avoid this?" He said the solution is to provide "simple, cheap, consumer friendly, high quality" service "respectful for our customers". McCaw's presence, his ownership of supplier NextNet Wireless, his spectrum purchases and his purchase of Clearwire--which has a significant leasing agreement with ITFS spectrum holders--all speak to his intent to be a contender in broadband wireless.
At the end of his talk, actual plans for his new venture still remained vague. What is known is that McCaw's Clearwire will offer broadband wireless service in Jacksonville, Florida and St. Cloud, Minnesota this summer. They will use technology from NextNet, whose equipment has been in service for some time in Mexico. The equipment requires no truck roll and the customer pitch is an easy, self-installed high-speed Internet connection. Its differentiation from DSL and cable is that can be used anywhere in the service area.
McCaw founded McCaw Cellular and sold it to AT&T in 1994 for $11.5 billion. He is now setting out to become a major player in broadband wireless. He has a mixed track record, but McCaw is certainly a contender who should be taken seriously.
"Spectrum Is the Lifeblood"
Regulatory agencies around the world hold the keys to broadband wireless, since they are the ones that control spectrum. Spectrum was a particular key focus of this meeting, since it was shortly before the FCC was to issue its order restructuring the MDS/MMDS and ITFS bands (see news, above).
FCC Commissioner Adelstein was eloquent on the subject, saying "Spectrum is the lifeblood for broadband wireless" and "We need to get spectrum into the hands of people who can use it." Because he comes from South Dakota, a fairly rural state, his attitudes are very influenced by the needs of underserved rural constituents. He believes that unlicensed spectrum is an effective business model in rural areas. He made an important point when he said: "VoIP is only as good as its broadband connection."
The FCC has formed a Wireless Broadband Access Task Force, several of whose members spoke at the conference. Their role is to form "spectrum policy for the 21st century."
Commissioner Abernathy explained a common thread in many recent proceedings: the "smart radio" proceeding, the "interference temperature" model, the "secondary spectrum" market, and using the "white spaces" in the broadcast TV spectrum. Each was about "finding out if this approach allows more intensive use of spectrum".
John Muleta, Chief of the FCC's Wireless Telecommunications Bureau (WTB), said it another way when talking about the MMDS/ITFS reworking: "It's about making the highest and best use of the spectrum" while still preserving the rights of incumbent licensees.
Several speakers referred in various ways to what they believe is the underlying set of equations at stake here:
The WiMAX Drumbeat
You've got to hand it to Intel. They certainly know how to get behind a technology and promote it. When we last attended WCA in January 2003, broadband wireless outside the home was struggling toward non line-of-sight technology. There were one or two technical meetings about WiMAX (the emerging 802.16 wireless metropolitan area network standard), but it was so low key that the term didn't even make it into our article. Fast forward to the present and WiMAX was almost everywhere at the show. The WiMAX Forum™, which in April 2003 had 10 members, now has 104 announced and more imminent.
The level of coverage and hype around WiMAX has created an interesting problem for the group. On the one hand, the more the drum is beat, the more people join the parade--we noticed someone whose title at Intel is "WiMAX Campaign Manager". On the other hand, several WiMAX Working Group chairs pointed out that some recent articles are setting unrealistic expectations. That is their challenge.
We met with the Chairs of most WiMAX Working Groups, including technical, marketing and regulatory. The WiMAX technical work seems to be proceeding quite well. They expect to have products built to the spec but not yet certified by the end of this year. Those products will be built against the upcoming IEEE 802.16d standard, which enables operation with an indoor unit (as opposed to an outside antenna). Interoperability testing is expected to start in 2005 with certified interoperable products in the second half.
The first mobility version of WiMAX, 802.16e, is not expected until about a year after the "d" products, with volume probably in 2007. Of course this is where Intel comes in. The goal for .16e is to reduce prices for broadband wireless CPE from the current $300+ mark to sub $100 levels and then incorporate it into laptop PCs. As a logical extension to Intel's Centrino campaign for Wi-Fi, Intel will put WiMAX on cards and build it into PC chips, enabling the PC owner to become a WiMAX customer. WiMAX will complement Wi-Fi, not replace it.
Many of the vendors on the WCA exhibit floor have previously supported proprietary approaches, and are now embracing WiMAX. For example, Alvarion announced its new "BreezeMAX" product. Airspan, Alvarion and Redline have announced pre-“WiMAX” products. Motorola's announcement was about significantly lowering the price of their proprietary Canopy product (to sub $250 levels in volume); they have joined the WiMAX Forum and we expect to see them announce support for WiMAX soon.
Two other WiMAX Forum developments were particularly noteworthy. The first is the formation of a Regulatory Working Group, headed by Margaret LaBrecque of Intel. Its purpose is to help create an environment favorable to widespread deployment of WiMAX systems, and to ensure availability and global harmonization of WiMAX-friendly spectrum worldwide.
The second development is equally important and concerns the growth in WiMAX service provider members: there are now 26, a huge increase, representing a quarter of the members. New members include British Telecom, France Telecom and Qwest. Since these are the people who will ultimately need to purchase the equipment and implement the service, their presence and voice in the process is essential. The WiMAX Forum has created a Service Provider Working Group to formalize their input to WiMAX planning.
Even with all the buzz about WiMAX, there were other stories to be heard at WCA. Jon Hambidge and Madelyn Smith of IPWireless made sure we heard their view that there's no need to wait for WiMAX, because their technology already accomplishes its goal today. Their system uses UMTS TDD technology: UMTS (Universal Mobile Telecommunications System) is a mobile network technology for broadband delivery over 3G systems; TDD (time division duplex) is one variant of UMTS - most 3G systems use the more common FDD (frequency division duplex) approach.
This February IP Wireless helped to launch the Global UMTS TDD Alliance. It includes many service operators, plus such vendors as Samsung and UTStarcom, for a total of 40 members. It's important to note where it was launched -- at the 3GSM World Congress. This provides an interesting perspective on the two different ways the industry is approaching mobile broadband wireless: The UMTS TTD camp comes from the mobile phone side (as is obvious from the 3G in the event name) and expands into broadband; the WiMAX camp starts from broadband and moves into mobility in the second phase.
Hambidge made several key points about the Global UMTS TDD Alliance:
UMTS TDD products are finding success largely with non-traditional operators who want to provide ubiquitous broadband services. The Alliance's success stories to date sound good, but they are battling momentum on the one hand from 3G FDD advocates deploying WCDMA, and on the other from the steam behind WiMAX.
What's Next?--From "Broadband Home" to "Broadband Anywhere"
Why are Wi-Fi hotspots and broadband in hotels gaining in importance? Why are operators rolling out networks with UMTS TDD and similar technologies from Arraycomm, Flarion and others? Its all about "personal broadband": broadband to the person, not to the place. The broadband home is only part of the journey; these emerging technologies support the user anywhere.
Korea, already the leader in broadband penetration and uses, is moving in this direction. Its "WiBro" strategy is all about "portable broadband Internet," spurred by the Ministry of Information and Communications. We'll learn more and revisit this in a future article.
We've run out of room to write about additional topics like interference temperature, the coordination of license exempt spectrum, why people think the 700 MHZ band should be watched, and lots more. WCA President Andrew Krieg did a terrific job of pulling together a very meaty program.
Where are we on the road to personal broadband? And what is the likely future for personal broadband provider Arraycomm, when the WiMAX camp has so much momentum behind it? Those are the questions we wanted answered when we set up an interview with Arraycomm's Director of Marketing Steven Glapa. We wrote about Arraycomm's iBurst technology a year and a half ago - see ArrayComm -- Another Approach to Ubiquitous Wireless.
Glapa's answer was surprising, given that we saw WiMAX and iBurst as competitors. He believes that whoever "wins" in the long term, Arraycomm stands to benefit either way.
Arraycomm's core business is its IntelliCell adaptive antenna processing technology. Using sophisticated signal processing to detect where a user is transmitting from, it directs the antenna array to focus the return signal there rather than broadcasting widely. This results in efficient transmission and low power consumption by the user's modem. Arraycomm says this technology is helping to serve 15 million mobile subscribers today in China, Ethiopia, Japan, Thailand, Malaysia, the Philippines, Taiwan and the United Arab Emirates. ArrayComm benefits through technology licensing.
Arraycomm says service providers working with early broadband wireless systems are finding they will need "smart antenna" technology to achieve their goals. Arraycomm thinks WiMAX will need it to optimize the range and capacity served by broadband wireless base stations, with fewer needed to serve an area. That translates to CapEx savings--and perhaps the difference between a viable business case or not. We don't know whether WiMAX vendors agree with this, but we have seen references to "smart antennas" so we suspect they do.
That's not to say that Arraycomm is writing off the sales potential of iBurst--far from it. If you visit their Web site you'll see that iBurst is front and center, while antennas are buried in a section called "products and services". The natural next questions are: "Who is Arraycomm's target market for iBurst?" and "Why would service providers buy it rather than other solutions?"
Glapa's answer is that some providers in developing countries and CLECs in the developed world believe in the vision of personal broadband--service which does for data communications what the mobile phone does for voice. Some of these providers believe "the clock is ticking very quickly" and can't wait for what's promised in the future. WiMAX is not available today, and "pre-WiMAX" products won't support mobility. So it comes down to the products available now and the economics of the business case using each. When that work is done, Arraycomm believes they come out ahead.
Personal Broadband Australia
To see iBurst technology in action, Glapa points to the experience thus far in Australia. Personal Broadband Australia (PBA) has built out infrastructure which covers 300-400 square km with 12 base stations. When Glapa was in Sydney, he said he got 1 Megabit/sec while being driven in a taxi.
The business structure is quite interesting. PBA's consortium partners include Arraycomm, Crown Castle Australia, ozEmail, UTStarcom, Vodaphone Australia and TCI, a specialist management group. PBA builds the network and acts as the wholesale distributor for wireless services; multiple retail distributor/service providers sell services and have the relationship with the end user.
Australia is turning out to be an interesting testbed for wireless broadband, since iBurst is not without broadband wireless competitors. Unwired, another company owning Australian spectrum, is using Navini's technology to construct a similar network in Sydney. However, Navini's current technology does not provide for mobility (use in a moving vehicle) but only provides portability within the service area (use at any served fixed point outside the home).
The availability of multiple types of broadband wireless should provide a living lab for seeing what segments of customers sign up for each of the services and investigating how customers decide what choice to make. There are lots of variables: what needs they have, how much they are willing to pay, coverage area and lots more. Your editors have no choice but to schedule a trip to Australia soon to investigate in person how this is turning out.
Pulse~Link invited us to meet with them a few weeks ago in Boston, where they were sponsoring and exhibiting at an ITU Ultra Wideband task group meeting. We spent several hours with John Santhoff (founder and CTO), Bruce Watkins (President and COO) and Tom Kovanic (VP of Marketing).
We have written previously about ultra wideband (UWB) and Pulse~Link - see What's Next for Wireless Networking. Founded four years ago, they have announced many applications for high-speed UWB: over hybrid fiber/coax (HFC) networks; over home power lines; and wireless in the home.
In Boston, Tom showed us all of these in operation using early versions of their technology.
Pulse~Link has developed an integrated circuit it calls a "media-diverse UWB Software Defined Cognitive Radio (SDCR) solution." They say it will support all three media types--cable, power line and wireless--simultaneously on the same chipset, and project very impressive "target data rates":
Like other UWB approaches, all of these share the spectrum without interfering with existing services--video over cable, Wi-Fi networks in the home--carried over the same system.
John explained the technical approach Pulse~Link uses to achieve these speeds: the data is coded by the different times between very narrow pulses -- they call this a "pulse recurrent frequency" approach. Other "flavors" of UWB use different means to encode data.
With many different approaches to UWB, the IEEE 802.15.3a Task Group for high-rate wireless personal area networks has so far been unable to agree on a single approach. To break the impasse, John is leading a drive to adopt a "common signalling mode" (CSM) to provide an "etiquette" for UWB devices based on different approaches to coexist, coordinate their actions and interoperate in the same wireless network.
More on Metadata -- A Dialog with Gracenote
Several months ago, we wrote about our experience with GetDigital -- see Get Digital Part 2: It's The Metadata, Stupid!. We compared GetDigital with CDDB, the online database used by most PC programs to obtain metadata when playing CDs and recording or "ripping" them to hard drives.
We first wrote about Gracenote more than two years ago -- see CDDB - Gracenote. At that time, their CDDB database was maintained almost entirely by end users, leading to inconsistency in data entry and classification.
Shortly after we published the GetDigital article, we received a nice note from Kathryn Shantz of Gracenote, pointing out CDDB improvements that we were not aware of. That led to an exchange of email with Kathryn and a telephone interview with Ross Blanchard (Director of Marketing and Business Development).
In her email, Kathryn said "it's great that you're writing about metadata - while relatively hidden, this is one of the most important aspects of the digital music revolution! Gracenote's business was built around serving this need -- with the goal of making digital music easier to use." She described "some of the things we've changed to improve and extend the service since you last wrote about us:
In our telephone discussion with Kathryn and Ross, we learned that the CDDB database now includes nearly 3 million CDs and more than 36 million songs. Each day, users from ninety countries submit about ten thousand new albums to CDDB. In the US, Korea and Japan, Gracenote has editorial staff to "vet" the entries and "lock them down" to prevent modification by users. Because of the volume of entries, the editors are focused on the most popular content; of the most popular CDs, "the high 90% are locked down."
For the smaller labels, Gracenote has a "content partner program" so that they can directly submit album and track metadata for their own CDs and lock them down.
Gracenote does not lock down the genre metadata, which is highly subjective. They allow for two different genres for each album, artist and song.
Access to the CDDB catalog varies a great deal by country. For example, in Germany, access is 30% local (German CDs) and 70% international, while in Japan and Korea it's 70% local and 30% international.
Gracenote licenses a CDDB Software Development Kit (SDK) to software developers. Most PC-based CD players and recorders use this kit, which is also available for Apple and Linux-based systems. Gracenote also provides an "Embedded CDDB" solution; for portable devices and others without an active Internet connection, this provides a copy of CDDB for storage on a hard drive.
Gracenote has a new system called MusicID which uses waveform analysis to create a "fingerprint" of each track; the track can come from any source: records, cassettes, CDs or even radio. (This is very different from the original CDDB recognition, which is based on track-length information specific to CDs.) Once the track is identified, the CDDB database provides all the metadata. Gracenote now has waveform fingerprints for over 3.6 million tracks, and says it is adding "over 25,000 a week."
Gracenote has patents pending on the recognition technique, and offers a MusicID SDK for license to device developers. We asked whether any products were available yet, and Ross said "it has been licensed to half a dozen folks - there's an Onkyo product but it's for the Japanese market only."
We have a large collection of LP records, and we've started recording them to a hard drive so we can play them through our network. We've been doing it with what's available, and it's a pretty tedious process; since nothing we've seen includes a link to CDDB, we have to enter the metadata ourselves. We're hoping to see someone bring out an LP recording system using MusicID to make it a lot easier; maybe it's not so far away.
We were pleased when the latest promotional mailing from our local hospital contained not one, but two mentions of broadband. It seems there is growing recognition of the real-world benefits broadband can bring to home health care.
If you're as intrigued as we are by the potential, join us at Healthcare Unbound in Cambridge, MA on July 8th and 9th. Its focus is the convergence of consumer and healthcare technologies. We're participating in an optional post-conference workshop on the afternoon of July 9th, to talk about "the broadband home--how healthcare ready?".
Reader and colleague Vladimir Prodanovic sent us a note from the Netherlands: "I have become a member of FTTH Council Europe. It is maybe interesting for you and your people to know that last week there was a meeting in Brussels and presentations are available online. Go to Events and Day 1 and Day 2 (interesting presentation from Ministry of Telecom from Japan with some number of FTTH)."
