TechnologiesAustin, TX
CEO, President and Founder: Navicent Technologies Inc developed
Broadband Equipment, Semiconductors and Intellectual Property for the HFC
Cable marketplace. The Company developed its closely coupled Cable Modem
Termination System (CMTS), Customer Premise Systems (Cable Modem, residential
gateway, digital set-top box) and Super Node (RF aggregation) products.
Navicent delivered to the market a 400 Mbps cable network at 8X density
nearly 10 years ahead of the market. As CEO, President my responsibilities
included:
Corporate: As president
I created and drove the vision and focus of the Company. I was solely
responsible for the completion of business plans, negotiated rounds of
financing & proper legal corporate paperwork. Also I opened the
facility, defined/established benefits plans, hiring plans, facilities,
payroll and accounting plans.
Technical: As co-founder I
lead product definition (MRD), external/internal architecture and
intellectual property generation. I wrote and filed approximately 120
patent claims in the areas broadband access Networks, network switching,
switched digital video, digital video recording, advertisement insertion
and high bandwidth interactive networks. Eventually, several of the
technologies were adopted by the cable industry, most notably DOCSIS3.0.
My most important
task was to qualify and hire the engineering management teams and set up
the appropriate benefits plans for retention. The teams consisted of ASIC,
PCB, Software, OS, System and RF engineering. Secondarily, from a design
perspective I defined the corporate development flow and procedures
including logic capture and simulation via Verilog simulation, synthesis,
layout, verification and test generation for both FPGA and ASICs. The
company also developed its own board development and layout capabilities.
In particular I participated and lead the architecture and development of a
Carrier Class DOCSIS CMTS, DOCSIS MAC/Security (DES) software/hardware
acceleration, multi-channel QAM modulator & demodulator, RF
Up-converter, Gigabit to multi-channel QAM network switch, RG (CM based on
MIPs Core, Router, VoIP, Video over IP, Linux OS and firewall), IP &
MPEG2 transport mixing, MPEG2 decoder/encoder, VOD server software,
Personal VCR software, DNS, MPLS, Storage/Delivery and Multi-stream DVD
quality VOD and video teleconferencing (H.3XX, H.2XX, MPEG4, DES, Security,
etc.) algorithms. Each of the designs was set up for high volume
manufacturing utilizing both local and Asian custom manufacturing.
Sales &
Marketing: In
this role I established and implemented an integrated marketing, sales,
product development and manufacturing strategy. This included the
development and implementation of a multi-year plan that identified key
products by segment, target customers, sources of supply, hiring of skilled
professionals, organization structures, optimum sales channels, market
positioning, pricing strategies, investments, budgets and resources to
enable the following business processes: Order acquisition, product
development, product realization, and order fulfillment. Eventually, the
process defined led to the setting up of a WW Sales operation. The team
presented and met with nearly 15 cable company executives including several
of the top c-executives from Time Warner, ATT, Cox, Comcast, etc. In
addition the team and myself developed direct relationships to sell the
company to several technology F1000 OEMs including Nortel, Tellabs, Cisco,
S. A. and Motorola
