What is the value?Improvement Value Estimation
• For search space improvements we choose 25%. • For higher density phase encoding due to phase noise improvement, we choose
200%. • For frequency-based improvements, we choose 25% for an overall raw capacity
improvement floor of 250%. • For better beam-forming due to precision positioning, we choose not to include this
technology in the low side estimate since it is somewhat speculative. For the high side estimate 50% is used.
• For cell-handoff and precision Quality of Service (QoS) improvements due to precision timing, we choose an overall value improvement of 200%. Here, we apply the term QoS to network usage prioritization and predictability with respect to performance parameters including delay, error rate, and throughput.
• Even as a floor, we significantly reduce these expected low-side improvements prior to further use in our dollar valuation model to reinforce its conservative nature.
TABLE 1. HFGW Technical Improvement Value Estimate.
Low-Side Technical Improvement (High-Side Reference) Search Space 25% 50% High Density Phase Enc. 200% 400% Frequency Noise (TBE) 25% 50% Positioning/Beam Forming 0% 50%
Raw Capacity Improvement 250% 550%
+ Precision QoS Enablement 200% 1000%
Model's Simplifying Multiplier: 450% 1550%
What is the value?Subscriber Value Estimation
• Applying these multipliers to a conventional High Bit Rate Wireless Market Offer (conservatively—for this model—priced at $100/month/2Mbps), we obtain a reference MRC/subscriber low-side value added due to the HFGW FTS of $275 (Table 2).
• Note that MRC = Monthly Recurring Charge. This includes a 25% $/mbps discount from conventional costs due to supply increase and demand elasticity.
• Further, in all significant cash flows (post year 2), we utilize a still more conservative estimate ranging from ~75-15% of this reference value.
TABLE 2. HFGW MRC Subscriber Added Value Estimate. Reference MRC / Subscriber Value Add Mbps $/month $/Mbps/mo High Bit Rate Wireless Market Offer 2 $ 100 $ 50
Simplifying 2.5x bit rate multiplier from raw capacity improvement 5 $ 188 $ 37.50 *
Simplifying 2x $value multiplier from precision timing/QoS enablement 5 $ 375 $ 75
Reference: MRC/subscriber low-side value add due to HFGW FTS $ 275 * 25% $/mbps discount from conventional
What will make it happen? Suggested Next Steps
• First Step – Design, develop, fund, and perform HFGW detection experiments to detect background (relic) GW radiation to prove detection technology.– One example approach: Li, Baker, & Chen, 2007
• Second Step – Design, develop, fund, and perform HFGW generation experiments to generate GW radiation in a laboratory environment.– One example approach: Woods & Baker, 2005– Use previously proven detection approach
• Near Term Development – Develop and miniaturize HFGW technology for use in the FTS application.
• Long Term Follow-on – Develop HFGW technology for use as a communication medium.
Early Technology Adoptersfor HFGW Frequency Time
Standards
G.V. Stephenson, 28 Oct 2006
Some Options for the Early Adoption of Frequency Time Standard HFGW Technology
• Supplemental FTS to Improve Navigational Systems– A central reference HFGW transmitter could be built– HFGW Receivers could be placed on each GPS satellite– The result would be a reduction in FTS errors of GPS
• Supplemental FTS for High Speed Network Improvement– Very high speed networks require GPS conditioned FTS to maximize
transmission rates– The use of higher accuracy HFGW FTS would allow even higher bandwidth
data rates by allowing more accurate frame sync
• The Ultimate in Survivable Strategic Communication– Strategic com does not require high bandwidths– Low bandwidth communications could be achieved by buried first
generation HFGW devices– Buried transmitters and receivers would be impossible to destroy
