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

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
Todays 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
Todays 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
