  1. IntroducingReal-time Monitoring System(RMS) Automated Data Collection and Analysis by

  2. Engineering Trends • Wireless networks are getting more complex • Increased Features • Higher Density of Cells • Migration to 3G • Manual Drive Testing Cost Increasing Exponentially • Requires expensive equipment • Requires expensive engineers

  3. Engineering Trends (continued) • System Quality Will Degrade • Fewer drive test vehicles • Increasing number of cells and system complexity • Cycle Time to Fix problems will Increase • More complex systems • Fewer drive test vehicles

  4. Today’s Environment Network problems are increasing Services offerings are increasing Network Complexity Features Web Audio Video Car Navigation Voice Short Message Email Current Future Cost of manual drive testing is increasing Cycle time to fix problems Time Cost Future Future Current Current

  5. Manual Drive Testing Cost vs. System Quality Cost Quality Future Current Cost of manual drive testing will increase while system quality decreases

  6. Automatic Drive Testing

  7. Automatic Drive Testing • Low cost data collection units • Automatically collect data • Store data on central server • Does not require people to drive test • Automatically identifies problems and notifies engineer • Ten times (or more) as many drive test units

  8. Enhances Productivity Manual Drive Testing Automatic Drive Testing Data Collection Processing Analysis Analysis Data Collection and Processing is performed automatically increasing productivity dramatically

  9. Economic Benefits • 98% cost savings over classic drive testing • 1251% more geographic area covered • Increase annual per market revenue $17 million

  10. Automatic Drive Testing Cost vs. System Quality Cost Quality Future Current Cost of drive testing will decrease while system quality improves

  11. Cycle Time to Fix Problems - Automated Drive Testing Time from problem identification to problem solution Automatic Drive Testing Manual Drive Testing

  12. Automatic Drive Testing provides 10 times (or more) more data Manual Drive Testing Automatic Drive Testing

  13. Need less engineers per cell sites • Manual Drive Testing • Few cell sites can be • managed by one engineer • Automatic Drive Testing • Many cell sites can be • managed by one engineer

  14. Collected Data is Centralized Data Data Data Data Data Data • Manual Drive Testing • Data is Decentralized • and Disorganized • Automatic Drive Testing • Data is Centralized • and Organized

  15. Accessing Data is Simple Data Data Data Data Data Data • Manual Drive Testing • Accessing data is difficult • Automatic Drive Testing • Access data from any Web Browser

  16. ZK’s Real-time Monitoring System (RMS)

  17. ZK’s Real-time Monitoring System • Low cost multi-phone, multi-technology capable remote control units (RCUs) • Central server for data storing, analysis, RCU administration • Internet based technologies for scalability and ease of access • Alerting for automatically identifying problems • Measure Voice, Data and Audio Quality

  18. Real-time Control Unit (RCU) • Reliable • Simple installation • Simple antenna • Multiple networks • Multiple technologies • Future enhancements • Identify alert conditions • Up to 256MB memory capacity

  19. 2-Phone RCU Hardware Architecture 1st data collection phone 2nd data collection phone GPS Receiver Required Processor Board Option Wireless modem DSP Audio Quality Measuring Scanner CF memory

  20. 6-Phone RCU Architecture 1st data collection phone 2nd data collection phone 3rd data collection phone 4th data collection phone 5th data collection phone 6th data collection phone Required Option Processor Board Scanner DSP Audio Quality Measuring GPS Receiver Wireless Modem CF memory

  21. RCU Data Logging • CDMA, GSM, TDMA, iDen, EAMPS • Voice • Call processing events including handoffs, channel, RSSI, Tx Power, BER, FER, RxQual, SQE, Neighbor channels, over-the-air messages, and more • Uplink and Downlink Audio Quality • MOS value on multiple phones • Compare networks • Data • Failed connections, Trace route, % retries, data throughput, latency, FER • Scanning options • CDMA PN, GSM/BSIC, iDEN, TDMA, EAMPS • Alarm events • Call blocks, call drops, poor audio quality, interference poor coverage, phone off, no service,etc.

  22. RCU Software Architecture RCU FTP Data Transfer GPS Wireless Modem Cellular Phones RS232 RS232 RS232 Main Processor TCP/IP FTP Audio Audio Quality Measuring Memory Memory

  23. RMS Server • Access from any Web Browser • Reports, Charts, Maps • Audio Quality Measuring • Alerts • Oracle database • Large data handling • Simple software upgrades • Scaling capability

  24. RMS Server Architecture RMS Server Alerts Servlet RCU Configuration Servlet Mapping Servlet Administration Servlet Login Servlet Reports Servlet Application Server FTP Server Database (with Spatial) Street Data Cellular Data Audio Data Ethernet/ Internet To RCUs Audio Quality Measuring T1 Lines HTML/Javascript HTTP Server Java 1.3 Plug-in Netscape or IE (100% JAVA Src code) Client

Audio Quality MeasuringData Transfer Public Telephone Network Audio RMS Server T1/E1 Lines FTP Data and Audio RCU FTP Data LAN Cellular Network Wireless Ethernet Uplink Send Speech Clip Send FTP Data Measure Uplink Audio Quality Receive FTP Data Downlink Measure Downlink Audio Quality Receive FTP Data Send Speech Clip Send FTP Data

  26. RCU Configuration • Autodial • Data collection times • Blackout areas • Server IP address • Add, change delete units and groups

  27. Alert Configuration • Only generated under abnormal conditions, when % exceeds baseline + threshold (user programmable) • Blocks, drops by zone, twice per day • Email alert indication to three people • Additional alerts will be added

  28. Alert Display • Alerts displayed for each zone • User can acknowledge alerts and add notes • Display preferences can be modified

  29. RCU data filtering • Transmit only “bad” data • Conserve wireless bandwidth and database size • User programmable filters

  30. Data Analysis • Automated reports, charts, maps • Interactive analysis • Sharing of results • Immediate notification of alert condition • Data filtering • Export to third party applications • Access from any PC

  31. Maps • Shared and personal maps • Stored on server • Filter by date/time, geographical area and data type • Save maps for sharing and/or later use

  32. Mapping Analysis • View multiple layers of data on a single map • Dropped call and blocked call events • Browse individual data points • Cell Trace data point to serving sector • Binned and Point Data • Message Decoding

  33. Map Layers • Click and add data layers • Display multiple data layers on a map • Filter by time, date, unit and phone

  34. Map Display Cell/Sector trace lines Blocks and Drops Properties window Displays all data Logged at selected point on the map Cell sites with sector, angle and azmith

  35. Map Offset and Message Decoding • View Drop, FER and Layer 3 messages simultaneously • Decode Layer 3 messages • Detailed diagnosis of dropped call Layer 3 messages FER Dropped Call Decoded Layer 3 messages

  36. Binning • Quickly display data for entire Market or Region • Macro view of network performance • View by day, week or month • 100 meter bins • Drill down into problem areas

  41. Customer Comments "We can do more with less. Our engineers can spend more time analyzing the data and less time driving around.“ "We can manage many more cell sites with the same number of engineers." "We can identify and solve problems in the network before they affect our subscribers." "As we add complex 3G features and capabilities this system will allow us to properly manage network performance." "Switch data is helpful but this tells me where my drop calls happened and it provides the data from the phone perspective to help troubleshoot it." "One sixth of our wireless PC data users had 80% blocking and we didn't know it until the RMS system started monitoring our network." "We needed a system that would provide continuous drive test data to feed our frequency planning software. Now we have found it." "A product that measures voice and data on multiple networks, doesn't cost much and doesn't require an expensive engineer to drive around. That's incredible!".

  42. Summary • Automatic drive testing • Improves Quality • Decreases cycle time to fix problems • Identifies problems sooner • Reduces capital requirements • Reduces manpower requirements • Quality improvement at lower relative cost • Upgradeable for future enhancements
