urban environments
• Accurate vertical position
• Fast time to first fix
• Fully managed network Wide Area Broadcast Network
• Highly synchronized beacons, with deployment optimized for location
• Encrypted signal on licensed spectrum, similar to GPS
• Broad coverage from minimal sites
Limited Receiver Impact • Firmware upgrade to typical GPS
digital baseband: standalone solution
• Handset integration largely limited to band support
• On-device computation of location
• Reduced power consumption
Limited Application and Core Network Impact
• Designed to leverage existing elements with configuration to support NextNav information
• Similar to “Standalone GPS Mode” call flows

NextNav is deploying a terrestrially-based positioning constellation, featuring
significant technical commonality with GPS

Key Principles & Innovations • Network architecture effectively results in a terrestrial positioning constellation, featuring significant
commonality with GPS
– Timing-based system, using highly synchronized terrestrial transmitters for device-based trilateration
– Wide-area network architecture, providing consistent indoor service across coverage area
• System designed for minimally-disruptive adoption in mobile handsets and other devices
– Re-use of GPS digital baseband
• Air interface-agnostic system – allows for evolution of location technology independent of air interface (2G, 3G,
4G etc.)
• Unique height system results in 1 – 3m vertical precision by encoding real-time environmental reference
information in positioning data payload
• Unique business model – shared network (similar to GPS) across multiple parties ensures costs are
competitive
– NextNav deploys, manages and runs the network on a nationwide basis

Communications Safety, Reliability and
Interoperability Council Trials (“CSRIC”) • In 4Q12 the FCC’s CSRIC advisory group held a comprehensive, independent trial of location technologies for
indoor E911 in the San Francisco / Silicon Valley area.
• Joint effort by Public Safety, technology vendors and national wireless carriers. Results released March 2013

CSRIC Test Protocol Review
• CSRIC 3, Working Group 3 was chartered by the FCC with, among other things, creating an information base
from which indoor location accuracy standards for E911 could be established
– WG3 consists of technology vendors, public safety representatives and the four major U.S. wireless carriers
• Test program was performed by a 3rd party (TechnoCom), and was completely blind to participants
– Over 13,000 test calls for each participating vendor at 75 indoor test points per building (including deep building
core)
– Test bias towards dense urban / urban (70% of test points)
• Extremely rigorous test process, appropriate for mission-critical applications, resulted in some vendor attrition,
with performance for all vendors impacted (7 expressed interest, 4 started and 3 finished)
• Results published in March 2013
