1. Extending the network’s edge far beyond what was possible

2. C-LAN Micro cellular network topology provides M2M, Bi-directional IP access to low power, short range, battery operated devices/ sensors. C-LAN does not require any ambient RF Infrastructure (WiFi, large scale cellular) operates outside of IT Domain. C-LAN requires a single IP interface (Ethernet/cellular modem) regardless of C-LAN coverage area. C-LAN can be installed into existing structures with no retro-fit, available AC power is the only requirement. Battery/solar power can be used for temporary, Ad-Hoc network capability if no AC available. This would indicate C-LAN could be used in emergency/field application

3. Master Unit Up to 64,000 C-LAN Cells Master acts as gateway to web app via IP/modem Master manages network timing/control for network formation & Bi-directional packet transport Single Master is able to provide RF coverage of 192 Million square feet (2500-3000 sqft/ C-LAN cell) Ethernet/WiFiCellular Modem AT&T Server Unlimited number of active/passive C-LAN Tags

4. Master Unit AT&T Server C2 C9 C8 C3 C6C6 C7 C1 C4 “Segmented Cluster” network geometry, i.e. Buildings, Airports, Warehouses, Shipping containers thru Port of Entry and while in transit, digital home life environment. Network assembly algorithm maximizes bandwidth & minimizes latency regardless of geometry. CØCØ C5 C 10 C 11

5. Master Unit C2 CnCn C1 Linear Array network geometry “picket fence”, i.e. Border Security, perimeter monitoring and warning. C-LAN network assembly algorithm maximizes bandwidth & minimizes latency. AT&T Server CØCØ ~

6. Master Unit AT&T Server CØCØ C3 C4 C1 C2 Cell-Device RF Range Overlapping Cell Coverage Cell to Cell RF Range (Bi- Direction) Backhaul ~ 250m/2.5 GHz/20dBm ~600m/915MHz/20dBm Cell to Device RF Range ~10m/2.5Ghz/0dBm/250 Kbps ~100m/915MHz/0dBm/250 Kbps C4

7. Master Unit CØCØ C2 C3 C1 Device to Device Packet Exchange Bounced off Master Synchronous Asynch Synchronous backhaul. No self-induced packet collisions Full network BW assigned to sending cell via TDMA/Interrupt/Poll (based on network traffic density) Low packet density near cell, auto-acknowledgement between cell–device provides loss- less data transfer Multiple applications running on top of the ambient C-LAN, Security, HVAC, Real Time Video, any sensor available on market today, all sharing bandwidth with no packet collisions. Applications do not compete and self-collide. Asynch Temp Sensor Event Triggered Camera Pulse O ₂ Sensor Fixed/Mobile Equip and Supplies Personnel

8. C-LAN fills the gaps and extends the current technologies far beyond their limits! Segmented Cluster Multiple Schemes or Source Encrypted C-LAN Master via Ethernet/Modem

9. Successful Pilot projects completed: -Warner Bros Studios Burbank -Caught Harry Potter wand thief with C-LAN event triggered camera -TSA Washington DC -Recommended roll out to 600 U.S. airports -Report available upon request
