PA-ComNet Meeting Jan. 8, 2003
The meeting began at 7:35 AM in the Terman library. The attendees
introduced themselves, plus they signed the attendance sheet. Bob
Harrington began by referring to the reports on his and Manuel's visit to
Provo, Utah, in December that were posted on the PA-Fibernet site. They were
circulated to the other participants at Provo before posting so they have been
verified as accurate.
Provo is similar in many ways to Palo Alto, larger, younger, with significant
university population. They are ahead of Palo Alto in some ways.
They are using World Wide Packets equipment and Emtelle blown fiber for their
FTTH project. AT&T hired over 20 lobbyists who succeeded in getting a
state law passed that requires municipal utilities be wholesale retail
providers. This caused problems because the retailers all want exclusive
franchises. Provo would have preferred being a retailer. They have gotten
retailers to provide almost all services with the iProvo name prominent and service
provider names not at all prominent.
Bob showed the extensive program list. There are 48 music channels.
The basic channel is $10.95, 77 channels is $32.95 with no set top box
needed. Digital setup is $49.95 for 180 channels. Service is
provided by AT&T. VOD ranges from $.95 to $3.95, but it really isn't
offered yet. BYU will offer learning on demand which is essentially
unlimited. Pricing is 10-15% less than AT&T. There are 3 levels
of service provided by a local ISP who was not identified. Lowest is $14.95
for 256 Kbps. Highest data rate is 1-3 mbps symmetrical for $39.95.
Higher bandwidths are possible but would cost more. It is software
managed MAC address to MAC address.
Manuel Topete noted that Palo Alto needs to work with proven, feasible technology,
not something unique, or something no one else does at a price no one wants to
pay. Many technologies are being considered.
In Provo the system works extremely well, the total experience was great, but
there are many questions. The IP video works great, almost too well to be
true. We still have many questions. Only 50 of 65 homes have been
installed so far. The network isn't heavily used yet. They don't
yet have a business plan but they hired Neil Shaw to write one. He is the
same person that is going to write the Palo Alto plan. They have a video
plan, but don't have a full plan implemented yet. Pricing is unclear
because WWP won't quote costs yet. There is no video-on-demand yet, just
multicast.
Reed Majors of Minerva Networks noted they make the Provo headend
equipment. He gave a business plan to Provo previously.
Paul Venturella, telecom manager at Provo said they used IP video to be
futureproof. They use 3 fibers/home now, but will go to 1 fiber/home
later.
Discussion followed on technical capability, routing, possible problems with
bandwidth usage. Current customer premise equipment runs at 100
Mbps. They could go to 1 Gbps, but think it would be too expensive,
perhaps $2500. WWP pricing is a secret. Whenever they were asked to
give costs they changed the subject.
Jerry Scharf noted 100 Mbps is plenty fast enough for video so 1 Gbps isn't
needed.
Dan Swineheart noted bandwidth of the 1st level aggregation switch shouldn't be
any problem either.
Manuel noted multicasting IP video saves bandwidth.
Reed Majors noted there are over 9 million VOD enabled homes in the US and
there are statistics on them. In rural America 80% of viewers watch the 4
most popular channels. There is a FTTH system with over 25000 VOD users
in Milan that use an all-Cisco network. It has been run successfully for
3 years by Fastweb and is cash-flow positive.
Manuel said there is a FTTH Council made up of manufacturers and users who
recently held a conference in New Orleans. There were 3 simultaneous meetings
every day for 3 days. Question was asked of a panel with people from Wave
7, Alcatel, WWP and others if there is anywhere that VOD over IP is used
successfully, and they said no. In fact Cisco worked with Milan to
provide it.
The system is up in Provo and works, but there are less than 60 users so far so
it isn't stressed. The companies involved are good and the kind Palo Alto
can work with.
Reed Majors said Sure West in Roseville is working with FTTH and has 5000
customers. They are good resources. They also have hard cost data.
Manuel noted Palo Alto is behind other areas, but we can use other's experience
to make our efforts better. We can use analog if it works better and is
cheaper, or we can go IP digital video if it works better. IP video works
technically at small scale based on Provo. We want to see what works
best. When we tell people 1 Gbps is possible they want to know if we're
kidding.
Jerry Scharf said the capability of IP has been proven and costs are being
reduced IP won't solve all problems rapidly. There is lots of
investment and effort in the field and in 10 to 15 years it will be a very
minor incremental cost. The groups that are investing now are those like
us who are not invested in legacy systems. IP has limitations but it also
has great potential.
Manuel said they download a movie with Movielink in order to view
Chicago. Downloading all 790 mbps took 20 minutes from LA, but it can be
viewed during download if desired. Panel TV was 42" but the view was
about 6". Limit for the download was Internet speed, not local
speed. If the movies were stored locally the download would be far
faster. Super high bandwidth is more useful for an Intranet than for the
Internet. Dan Swineheart agreed, and said the Intranet is where the exciting
new stuff will happen.
Palo Alto could serve the entire community from 3 headends with 1200 channels
using IP video when it becomes fully developed. Manufacturers are flexible at
this point to grow the business. If we ask for it they'll provide it, and
then see how well it works.
Len Weisberg asked about QAM. What in the transmission method isn't
ordinary analog and isn't IP packets?
Radio only works in analog. Video on present systems is analog plus
digital. Present systems can deliver analog + digital with a compression
ratio of up to 16:1, although picture quality is far better with 6 or
8:1compression. Comcast provides VOD from local storage in Philadelphia
and several other cities, so it's practical.
Jeff Hoel said the important thing about the encoding method is how many
digital bits per Hz and the signal to noise ratio.
Reed Majors said a digital head end system can be cash flow positive in 1 year,
ignoring the cost of the fiber ring.
Use of blown fiber was questioned. Manuel said the cost was prohibitive
2.5 years ago, but it's gotten better, easier to work with and insert tap
tubules into a tube while on a telephone pole than to do fusion splices.
Provo estimated cost was $5 million for the fiber loop plus 250 home trial.
They have more fiber to run than we do. Worldwide Packets wouldn't give
cost figures, only would respond to RFPs. This was not helpful because we
can't issue an RFP yet because we haven't gotten approval yet. Another
concern is the technology will be skewed so that only 1 or a very few bidders
are possible. That isn't the intention of CPAU. The RFP won't be
tailored to limit bidders or suppliers. The existing system using Wave7
was chosen because they had a very good technical specification and offered the
best business test for the trial. It's a PON system with
point-to-point fiber, so in a way it allows study of both PON and
point-to-point in 1 system.
Meeting adjourned at 8:55 AM.
