  1. Network Management of Wireless Network Gerald Methé Bell Mobility

  2. Short Biography • Graduated from Cambrian College of Applied Arts & Technology (Sudbury, ON) • Electronic Engineering Technologist (3 year program) • Worked at CML Technology (Technologist & Programmer) • Air Traffic Control System (Com-node 2) • Mobile Radio System (Motorola MRCC) • Liberty System (911) • Worked at the Gatineau Hospital (Bio-Med Technician) • Laboratory Equipment • OR, ER & ICU Equipment • Telephone System (SL1) • Started at Bell Mobility in 1993 (Switch & RAN Technician)

  3. History of Mobile Phones • Analog Cellular Networks – 1G (1985) • Advanced Mobile Phone System (AMPS) • Used Frequency-division Multiple Access (FDMA) • Unencrypted, Vulnerable to Eavesdropping via Scanners and Susceptible to Cell Phone “Cloning”. • Talk Time of 30 minutes / 10 hours to charge.

  4. History of Mobile Phones • Digital Cellular Networks – 2G (1990s) • Two Systems Competed in Global Market: • European developed GSM (Global System for Mobile Communication) • U.S. & Canada developed CDMA (Code Division Multiple Access) • Prepaid Mobile Phones / SMS (Text Messaging) • Access to Media Content – Web Browsing (56Kbps) • Hand-held Devices have more Advanced Batteries (increased battery life whilst on the move)

  5. Today’s Mobile Phones • Mobile Broadband Data – 3G (2000s) • Packet Switching vs. Circuit Switching (for Data Transmission) • EV-DO Rev A (2.5 Mbps – 3Mbps) aka. CDMA2000 • HSPA (High-Speed Packet Access) (2Mbps – 14Mbps)aka. WCDMA • Media Streaming of Audio & Video • USB Port Mobile Internet / Netbooks • Smartphones, iPhones & iPads

  6. Today’s Mobile Phones • Native IP Networks – 4G (2010s) • WiMAX (offered in US by Sprint) • LTE (Long Term Evolution) • Will eliminate Circuit Switching and Employ an All-IP Network (Voice calls treated as Data / VoLTE) • Downlink speeds (Bell LTE network currently provides speeds of 75Mbps – 150Mbps) • Mobile TV

  7. CDMA Network (2G / 3G)

  8. HSPA/LTE Network (3G / 4G)

  9. HSPA/LTE Network (3G / 4G)
