WTRS Executive Interview
Interview with Eric Broockman of CEO of Alereon .
Oct. 9, 2006
George: Can you
tell us a little bit about your background?
Eric: I've been in the industry for about 27 years. I began
my career at IBM as a design engineer, rising through the ranks and
ultimately becoming a senior technical staff member. Then I went to
the “dark side” and went into management as a general manager. The
last General Manager's position I held was in charge of the signal
processing activities at IBM Microelectronics. Then I moved to
Austin to work for Crystal Semiconductor in January 1995, and was
responsible for a lot of the analog mixed-signal products. They had
a lot of networking products, things that worked in set top boxes,
and got them into the audio surround business. In 2000, I did my
first startup as the CEO of Alchemy Semiconductor, which was a
low-power MIPS-based processor company that was sold to AMD, and
recently got sold to Raza Foundries. I then went to Legerity, and
was one of the three executives there, as the VP of marketing. I
also managed one of the operating divisions. I was then hired to be
the CEO of Alereon, and was employee number one, starting on June
23, 2003.
That is sort of a high-level background. I come from engineering and
spent a lot of time with customers from a marketing standpoint as
well. I have a lot of operations background too, having been General
Manager of quite of a number of different businesses over the years.
George: As CEO, do you tend to focus more on operational
issues?
Eric: I would say that a great deal of my time is focused on
winning and retaining customers, so that the company can scale
appropriately. And I certainly have a lot of operational experience;
I spend a lot of my time internally preparing for strong revenue
growth as well.
George: What can you tell us about Alereon?
Eric: Alereon began as a legal entity in April of 2003. We started
the company by hiring a core team of engineers from another start-up
company in Huntsville, Alabama, and then moved them to Austin. Since
then we’ve added quite a number of people to the company. Alereon
was one of the founding companies of WiMedia, one of the founding
companies for the Multi-band Alliance that became the Multi-band
OFDM Alliance, and one of the founding members of the Wireless USB
Working Group, which turned into Wireless USB. So, we have been at
the forefront of this certification and standardization effort since
the very beginning. The original team that helped start the company
with me built the world’s very first Ultrawideband, FCC- certified,
pulse-based radio. Then we continued that history of “firsts” as
Alereon. We focused on getting chips that customers could use as
opposed to building demonstration units. We have always been a
chips-driven company and not a demo-driven company. In October of
2004, we were the first company to demonstrate a chip at data rates
from 53 to 480 Mbps per second. And then in October of 2005 we were
the first company to have a fully- WiMedia compatible chip, that was
because the standards had continued to evolve, and we support all
the modes and all the data rates. We recently announced at the
Wireless USB Developer's Conference that our chipset has gone
through full production qualification: temperature and voltage etc,
and is in stock and ready for delivery and for volume production. We
also continued our history of firsts there by demonstrating the
world's first wireless USB device MAC. This is in support of our
target market, which is primarily portable electronics. Certainly
you can use a chip that is designed for portable electronics in
other applications, but we decided to specialize in that regard. We
have also demonstrated a sustained data rate of 480 Mbps over the
air with a sustained throughput with our new MAC chip of 250 Mbps
per second. So this was the first demonstration of silicon using
wireless USB protocol achieving really good data rates.
George: We saw that demo last week, and one of the things
that impressed us was that the demo was operating at a distance over
one meter.
Eric: Yes, the team that was there told me that they ran the
demo at anywhere between 2 to 4 meters, depending on what they were
doing. Obviously at the lower data rates, the distance extends quite
substantially. To enable our vision in the portable electronics and
mobile space, which is driven by the strong value proposition UWB
has in power efficiency and in moving megabytes per milliwatt, we
knew that we had to get a PC host enabled, as well as other hosts,
so that is why we concentrated on a PHY chip first. We chose to go
on a strategic path of not doing a MAC chip for a host on a PC or on
a set top box, because we had a feeling that the large semiconductor
companies were going to target that. We wanted to be their PHY
partner, instead of a MAC competitor of theirs. To my knowledge, all
of my competitors chose to manage their risk and not trust that the
really big companies were going to follow through with a MAC. They
therefore split their resources and have done a host MAC and device
drivers for the host, as well as for the device side. That means
that their device side MAC is somewhat compromised and that their
resources are diluted because they are competing with the likes of
NEC, or any other company that goes into a host side MAC.
George: Is there anything else about your technology that you
consider to be unique?
Eric: From a differentiation standpoint, we try to be first with
production silicon that customers can ship as opposed to being early
with demonstrations that don’t ship. We are focused on mobile
applications, so we have the smallest footprint of any of the other
solutions, and we have the highest performance. One of the things we
were demonstrating last week, although we did not tout it at the
show, is that we have implemented a function we call
Wireless-on-the- Go. It makes our MAC behave sort of like a dual-
role device, except instead of implementing the cost of supporting
127 different links, we've implemented the host function to support
just one link, so that our MAC can talk to any device, be it another
Alereon device or some product that has somebody else's chip in it.
The reason that we wanted to do that is that if you have two
teenagers in Shanghai on the bus, the probability that there is a PC
on board shuttling data around is low. We didn't really want to wait
until there was TCP/IP peer-to-peer on WiMedia -- that might take a
while. We wanted the customer to be able to preserve the USB
software interface they are familiar with and be able to use PTP or
MTP or what-have-you. So we built this "on the go" feature so that
we can act as a mini-host and talk to any device, to allow what
therefore becomes a peer-to-peer transfer. So if you have a bunch of
pictures on your camera-phone and you want to send them to your hard
disk, video player, MP3-player, or video iPod, or however you want
to look at them, that you would be able to do that using standard
USB interfaces, using wireless USB protocol. Some companies choose,
when they did the host function, to try to include a lot of the
features of the whole protocol done on the host SOC. We chose not to
do that because we are targeted at the mobile space, and most mobile
SOCs end up with every real-time thread in the OS utilized and very
little MIPS left over in their host ARM processor. So therefore we
took the approach of offloading as many MIPS off the host SOC as
possible and making it so that it needed no real-time threads to
handle our interrupts. Therefore we differentiate ourselves because
no matter what kind of processor they have, a company could utilize
our solution and not worry about burdening their main SOC. Another
thing that's a little bit different is that every chip company, be
it a big company or a start-up, has to go through a “make vs. buy”
decision for each piece of the technology. We decided for strategy
reasons that we really needed to own all the key and important
intellectual property for our chips. So, we did our own MAC, we did
our own baseband, we did our own RF. (We actually have multiple RF
teams). We own and control all our intellectual property so that if
there is some issue with standards changes or whatever, we can
control our destiny and therefore be timely with new products for
our customers. In contrast, many of our competitors have purchased
their intellectual property from companies in India (for their basic
MAC function), or they have paid contractors to do their RF function
and therefore, although they can do a demonstration, they don't
really control their own destiny. We think that long term, if you
really want to be a player, you really have to have your own
technology. It doesn't mean that you might not buy a USB block from
a Synopsis or something. But when it comes to the fundamental
wireless USB MAC or the like, we think that is something that really
has to be owned by a company if their objective is really to be an
IPO company versus a company doing this for fun so they can be
bought. As an example, we participated in an announcement with ARM
some time ago, saying that we chose the ARM 968 processor as part of
our MAC sub-system and that we chose it because when you look at it,
it’s the most power-efficient ARM that they have in the ARM9 family
that looks like a big ARM7. All my competitors have something that
looks a lot more like an ARM924 type of hash-based chip; that uses 6
times more power per megahertz than what I use. They did that
because it was cheaper, but not because it was better suited to the
application. We are trying to build something that is well suited to
the application and will scale over time.
We have been the only company that has done full public
demonstrations of full DAA capability. We realize that we don't know
what the regulatory requirements for DAA will ultimately look like,
but we recognized long before others that this was likely to be
important in the 3-5 GHz band. And in fact, we proposed the DAA
concept to the regulators to begin with. We have demonstrated not
only band dropping, but also detecting other signals and notching
those signals. So we have done a demonstration where you can turn on
a cell phone and you can see the overtones of the cell phone right
in the UWB band. We detect that, and then notch out the frequencies
around that. So we are on the forefront of a type of cognitive radio
technology (we call it CogniPHY) that we think could be very useful
as the UWB market develops. That is an example of some of our
innovations in UWB.
George: Are you seeing a willingness in your customer base to
pay a higher price for some of these features that are more focused
on mobile solutions?
Eric: One of the things we did was put some very
mobile-oriented interfaces on our chip like SDIO, and like compact
flash. We did put a general-purpose parallel port on our chip as
well, so that companies that wanted to use our chip for some PC
peripherals in the early part of the market could do so. In the
early part of the market, we will be participating in the PC and PC
peripheral aftermarket sector through our PHY sales in partnership
with MAC companies, and as well as with people who choose to use the
parallel interface on our MAC chip.
From a cost standpoint, we know that the mobile market is just as
cost-sensitive as the PC market so we have been pretty sensitive
about implementing things that are cost-sensitive right from the
beginning. One of the reasons that we did Wireless- on-the-Go versus
a full USB host was not because we couldn't do a USB host, but
because it takes more memory, and memory is cost, and you don't need
a PC USB host inside an MP3 player, you just need enough of a host
to be able to make the connection.
George: That leads into a question about sales channels. We
talked to Synopsis and Eric Wong there and about having licensed the
Alereon PHY. What other kinds of sales channels do you have going
forward?
Eric: I had actually met with the CEO of Synopsis a long time
ago. His guys were actively trying to decide if they were going to
do a Wireless USB MAC or not. They were leaning that way since the
IP for their wired USB had been pretty successful as a product. We
both shared a vision of how large the Wireless USB market could be.
Alereon participated closely with Synopsis so that they could
develop a bunch of their different MACs. The reason we did this is
that we would like to be part of driving the adoption curve to be as
steep as possible. WiMedia, with our participation, was wise enough
to put a standard MAC/PHY interface in the specification (much like
10/100 Ethernet has the SPI interface). So, since we were going to
be in the PHY business, we wanted large companies to be able to get
started by purchasing intellectual property from Synopsis, or from
Wipro out of India, so that they could get into the game for a
relatively modest cost and just use a third-party PHY. Because when
a MAC goes in a system, in an SOC, the cost of the memory becomes
free since you are using the main system memory instead of on-chip
memory. And the die area for the rest of the chip is relatively
small so that means the incremental cost for a system probably goes
down 40% if you just have to buy a PHY versus buying a MAC plus a
PHY, because the MAC has been integrated. So that was actually part
of our strategy in working with companies like Synopsis. I don't
actually think of Synopsis as a sales channel, which was the basis
of your original question, but we have some of our own direct sales
guys that manage geographies and key accounts and they work with
major distributors that we have signed up, such as the brilliant
group of Macnica in Japan, or Mirtech group in Korea, or Edom out of
Taiwan. I am embarrassed to say that I forgot the name of one of our
distributors in the Far East at the moment, but I just got back from
vacation. So we have a set of representatives that we have been
working with, and that we are very happy with, that are representing
us on the ground in a variety of areas, along with our own direct
sales folks. We do believe in industry partners, we do know that we
are not as big as a company like Synopsis is, so we seek out
opportunities to partner with a company like Synopsis or with Wipro
or others.
George: As this market heads from adoption of technology into
products, what sort of interest in terms of applications are you
seeing today?
Eric: It’s been very interesting. We have seen a steady
increase over the last few years in the whole concept of Wireless
USB. If you will recall, since you have been following UWB for a
while, if you rewind to 2002, UWB and wireless video were used
together all the time. When we funded our company, when we went to
our investors, we said, "Hey, you could certainly use
Ultrawideband
for wireless video, but that's not really the target opportunity we
are going after. We want to get rid of all the USB cables, there’s
already a large installed USB base. There are lots of applications
that use USB. We want to allow those applications to be taken
forward wirelessly. We think that's really the killer app. It will
start in the PC aftermarket, go into the PC, go into mobile
electronics, and then go into consumer electronics."
Our view was that for wireless video, there were a lot of other
alternatives coming down the line. Everything from variations of
802.11a to variations of 802.11n to HomePlug2 to, believe it or not,
new furniture. If you buy a new wall unit that can accommodate a big
screen TV, you don't have to put the TV in a new part of the room
and then worry about how you are going to get the signal to it
anymore. So that is sort of the low-tech way to solve the signal to
big screen TV problem. One of the driving reasons that people have
the problem to begin with is that they buy the big screen TV and it
doesn't fit in the wall unit they currently have. So their room is
oriented in the way they want for watching TV, but now they have to
put the TV someplace different when really they would sort of like
to keep it the way they had it, and sometimes it’s as easy as "OK,
so I'll just get rid of that old wall unit and get a new one."
Problem solved. I don't know anybody who wants to keep moving their
flat screen TV around just to try it on different walls.
So we approached the market probably different than many others in
that era. We do think that all wireless televisions will end up with
wireless USB in them, with Ultrawideband in them. But we don't think
it’s because of wireless video necessarily. We do think it’s because
everybody who has a digital camera wants to send their pictures to
the most beautiful, largest screen they have in their house: their
flat screen TV. They will edit them on their PC, and look at them
there, but when they really want to enjoy them, why not put them
right on your television? We think that being able to do that on an
impulse, by just getting your digital camera nearby, and pushing a
button on your TV, is going to be a very desirable application.
You asked about applications. In the early market we will
participate in aftermarket applications like hubs and dongles and
cards and so forth, through our PHY sales primarily. As the market
goes into embedded applications, we see a great deal of interest in
the digital camera marketplace and believe that that is going to be
a pretty big market, as well as digital video cameras. Ultimately we
see it also penetrating into the cell phones and becoming a
mainstay, probably in feature phones first and then smart phones
that have some sort of a camera phone feature and then over time
becoming sort of a standard feature in the majority of all phones.
Our view is that companies like NEC or potentially Intel, or others,
are likely to have an inside position to dominate the host PC
market. We wanted to enable that, but don't necessarily think we
have a natural inside track to that market, given what we know is
happening out there. We wanted to participate to the extent that we
could sell PHYs, and we really wanted to be staged so that we could
enable the mobile market and help that happen faster and become as
big as possible.
George: Have you been looking at wireless 1394 and some of
the activities around the HANA Alliance?
Eric: I was the head of next generation networking protocols
at IBM back in late 1980s, so I have a lot of experience with
communications protocols starting in the mid 1980's going all the
way through until I left IBM and went to Crystal. Then I had
networking chipset responsibility at Crystal Semiconductor through
2000. So I have a pretty long history in the communications area,
not just the chip area, and so when I looked at all of that,
considered the PC side of it, it looked to me like wireless USB was
really a nice bus protocol, that ultimately WiMedia will use TCP/IP,
but that it will take more time. When it came to 1394, it is sort of
a niche right now and it is primarily being used for video and given
my earlier comments about video, I have just never been able to get
excited about doing anything in that market. Certainly there are
others that have and I do think that there is an opportunity there.
I am hoping one of our partners takes their MAC and uses our PHY and
we get some piece of that business, but we decided fairly early on
that the wireless video, including 1394, was not suitable for us to
target. And we also came to the conclusion that if you looked at the
rate of penetration of USB in digital video cameras displacing 1394,
it just didn't look like it was a good opportunity.
George: Is there anything else we forgot to ask?
Eric: What kind of company are you trying to build? We would
like to the number one UWB chip company in the portable space. Our
mantra, if you will, is that we want to transform and bring about
"Life Without Wires." We want to build a company, maybe because I
was an engineer that is the best place for engineers to work. Our
objective is to be an IPO company. Our strategy is not being built
around the question of what can we do to that makes it the easiest
possible way to be acquired as soon as we can. That is not what we
are trying to do. Statistically that could happen, and we are not
doing anything that would prevent that, necessarily, but
fundamentally what we are trying to do is the right thing by the
customers and the marketplace to position ourselves to be an IPO.
What we want is to be to the wireless USB market what CSR is to the
Bluetooth market. Those are really the objectives we have as a
company. The reason that I look at it that way is that for the first
hundred years of radio, with the exception of the very first radio
done by Marconi (which was a spark gap radio and which arguably was
an Ultrawideband radio), all radios have been narrowband radios. So
if I put on my big-picture thinking cap, I look at wireless USB and
cable replacement as being only the first generation of applications
that leverage Ultrawideband radios. It’s an enormous opportunity.
It’s bigger than Bluetooth and Wi-Fi combined. So it’s an enormous
opportunity right out of the box. If you look out into time, as
spectrum policy evolves, other frequency bands will become available
at different power levels, and my belief is that Ultrawideband will
actually become much more prevalent than just cable replacement at
today's tiny power levels for wireless USB. My belief is that it’s a
fundamentally different approach to radio, that given the density of
today's technology and the cost-effectiveness of UWB, that over time
you are likely to see 5G cellular (which is really Ultrawideband
based), not be narrowband based radios. So I look at it as a
transition in technology. The impediment to UWB in the marketplace
is regulatory policy, and the enormous financial momentum of
established narrowband radio, so it’s not going to transform the
industry, outside of cable replacement, overnight. But twenty years
from now there are going to be an enormous number of Ultrawideband
applications that are much broader than cable replacement. So I
think about it in those terms. I try not to have my George Jetson
hat on too much, we have to be focused, we have to get into the
market, we need to satisfy today's customers, but I don’t look at
this as the latest IEEE or ECMA standard that allows somebody to get
a company started, get it public, and wait to see what happens. I
look it as a fundamental shift in radio technology from narrowband
radios of the past to Ultrawideband radios of the future and we want
to develop not only an understanding of wireless USB, which we
already understand well, but of Ultrawideband using technologies
such as our CogniPHY DAA technology to transform the radio landscape
so that we can five years from now be the company selling not only
lots of wireless USB but starting to deliver what might be 5G or
might be the follow-on to 802.11n. I would like to not think we
would be a one trick pony. I think that this pony can go into a lot
of other segments over time and our objective is really to become a
billion dollar type of company.
