Connected Vehicles (CV) and Ultrawideband (UWB) for Location and Communication Based Train Control

Enhanced GPS vs UWB on 6th Ave

Enhanced GPS Ultra-wideband

Phase 1

Non-proprietary

Standards Based CV/UWB Many Vendors Low Cost Wireless Integrated Lighting Rapid Deployment Non-vital Advanced Cab Signaling

Phase 2

Vital CBTC/PTC

Challenges
Dealing with signaling vendors – minimal in Phase 1 only
Dealing with train car vendors – minimal in Phase 2 only
Vital safety certification of new technology
Costs
Phase 1 - $100M - $200M – Communications deployment and Cab signaling
Phase 2 - $100M - $200M – Full CBTC deployment
Compare to $20 billion cost for current CBTC technologies
Low life cycle maintenance costs

Biggest saving comes with easy installation in existing lighting during normal maintenance cycles. No major track outages for in track work and wiring.
