20. Scanning Receiver Applications For Commercial Cellular • Produces Measurements to Assess Performance and Diagnose Problems • Key Characteristics: Accuracy, Speed, Signal Level, Multiple Simultaneous Technologies • Crucial Data for Use in Planning, Deployment, and Optimization Tools (CLARIFY®) • Technologies: GSM, WCDMA, HSDPA, EDGE, CDMA2000/EV-DO, WiMAX, TD-SCDMA, and LTE (FDD & TDD) • Covers the Widely Deployed Bands: 450, 700, Japan 800, 850/1900, 900/1800, 1500, 2100, AWS, 2600, and 2500/3500 for WiMAX Benchmarking or Test and Measurement Solution OEM SYSTEM PCTEL Scanning Handsets GPS Receiver Receiver Ÿ WCDMA Ÿ EVDO Ÿ CDMA GSM Ÿ iDEN Ÿ Ÿ LTE (FDD/TDD) Network Characteristics Position and Call Status

21. Antenna Applications: Vertical Markets

22. SCADA Applications:Oil & Gas, Mining, Waste Water, Smart Grid • Instrumentation and Automation • Remote Monitoring and Data Transfer • Manufacturing and Process Control Products • Rugged Yagi Antennas For Remote Monitoring Units • Embedded Antennas For Flow Monitoring • Meter Reading Antennas • Infrastructure Antennas

23. Focus On Verticals Has Lead To New Opportunities and Directions Applications For Our Antennas Applications For Scanning Receivers Acquisition Ideas Marketing Activities (e.g., No CTIA or MWC Booths; Instead “SCADA in Oil and Gas”) Exposure - Through Defense Systems Integrators - To The Growing Problem Of Cell Phone Vulnerability

24. Current Risks • Audio eavesdropping • Trojans, viruses, and other malware • Data interception (e.g. email or text messages) • Spying using the Microphone, GPS, Bluetooth, WiFi, etc • Location Information; Tracking • Industrial Network Hacking • According to the U.S. Department of Homeland Security, attacks on critical infrastructure jumped to 86 from 11 the same period a year ago (New York Times, March 13, 2012)

25. PCTEL Secure™ Architecture • PCTEL Secure™ Leverages SE Linux and the IsoCore® (Isolation core) Technology • IsoCore Monitors Application Performance, Function and Anomalies • Protocol Driven Inspection and Action • PCTEL Secure IP Protocols Define the IsoCore Foundation • PCTEL Secure Leverages Android Policies and Secure Applications. 25

26. PCTEL SECURE™ Advantages • Behavioral vs. Taxonomic Analysis • Not looking for specific threats, viruses, files, or patterns, but rather any behavior not allowed in the policy • Policies • Temporal in addition to cryptographic and other isolation methods • Sandboxing, virtualization, etc. cannot provide this level of isolation • Device Support • Moves easily to new devices without the re-engineering efforts involved in porting virtualization or hypervisor solutions • IP Protection • Three Patent Disclosures

27. PCTEL Secure Timeline Patent filed on base technology in SCADA environments (includes fixed wired and wireless) Technical product requirements complete Patent filed on base technology (ProsettaCore™) PCTEL Inc. acquisition of all PCTEL Secure LLC stock and assets OEM agreement with device manufacturer complete Patent filed on secure kernel technology Provisional patent filed on base technology Prototype dual-mode device Baseline product complete

28.
