  • 5. ORIGIN of Wireless Communication
    • 1895-1901
    • Guglielmo Marconi
    • Demonstrates wireless communications over increasing distances
    1864 James Maxwell Predicts existence of radio waves. 1886 Rudolph Hertz Demonstrates radio waves.
  • 6. 0G 1924

  • 8. 1G
    • Advanced Mobile Phone Services (AMPS)
      • Deployed in US , Japan : 1983
    • Nordic Mobile Telephony (NMT)
      • Sweden, Denmark, Norway, Finland : 1981
    • Total Access Communication System (TACS)
      • British System, similar to AMPS : 1985

  • 10. 2G – GSM
    • Global system for Mobile
      • Based on TDMA ; Europe
      • 900 Mhz, 1800 Mhz.
      • Later 850 Mhz and 1900 Mhz in Americas
      • Quad Band ; World Phones
  • 11. 2G - CDMA
    • Code Division Multiple Access
      • cdmaOne or IS-95

      • Major success in Korea, Used by Verizon and Sprint
      • Easy Migration to 3G

  • 18. 2.5G GPRS 2001 Packet Data
  • 19. 2.5G - GPRS
    • General Packet Radio Service - An Overlay technology on top of the existing GSM systems.
    • Data rate = 56 – 114Kbps.
    • 4 MCS (Modulation and coding schemes) used.
    • Factors affecting downlink/uplink speed:
      • TDMA slots
      • Multi-slot class
      • Channel Encoding used.
  • 20. HSCSD
    • High-Speed Circuit-Switched Data.
    • An enhancement to CSD – Multiple timeslots used.
    • Data rates up to 38.4 Kbps (4 times CSD).
      • In reality supports 14.4Kbps .
    • Expensive than CSD.
    • Latency less that GPRS.
  • 21. 2.75G EDGE 2003 Packet Data CDMA 1xRTT
  • 22. EDGE
    • EDGE (Enhanced Data rate for GSM)
    • Superset of GPRS.
    • Data rate = 4 times GPRS.
    • 9 MCS (Modulation and coding schemes) used – Gaussian min shift keying and 8PSK.
  • 23. Evolved EDGE
    • Data rate = 1Mbps
    • Encoding technique – 32QAM and 16QAM.
    • Requires simple network enhancements with software update.
  • 24. CDMA 1xRTT
    • 1x is an abbreviation of 1xRTT (1x Radio Transmission Technology).1x refers to the no. of duplex radio channels.
    • Supports 33-35 simultaneous voice calls per 1.25MHz.(cdmaOne = 20 voice calls)
    • Encoding technique:
      • BPSK for forward and reverse link.
    • Data Rate = 153 Kbps/153 Kbps.
    • Software and minimum hardware update.
  • 25. 3G IMT2000 W-CDMA (UMTS) CDMA2000
  • 26. UMTS
    • UMTS - Universal Mobile Telecommunications System. Also known as W-CDMA.
    • W-CDMA uses the DS-CDMA and TDD channel access method with a pair of 5 MHz channels.
    • Requires new cell towers & frequency allocations.
    • Data rate = 1Mbps(theoritical)
    • Frequency bands:
      • Uplink 1885-2025 MHz (mobile-to-base )
      • Downlink 2110-2200 MHz (base-to-mobile).
  • 27. CDMA2000
    • EVDO Rel 0 (Evolution-Data Optimized or Evolution-Data only Release 0)

      • Encoding technique – QPSK and 16QAM
    • High Speed Uplink Packet Access (HSUPA) or EUL(Enhanced Uplink)
      • Data rates for Reverse link - 5.76Mbps.
    • Just a software update for most WCDMA networks.
  • 30. HSPA+
    • Evolved High Speed Packet Access (HSPA+)
    • Data rates:
      • Forward link - 42Mbps.
      • Reverse link - 22Mbps.
    • Encoding technique 64QAM .
  • 31. EVDO Rev A
    • EVDO Rev A (Revision A)
    • Also called as EV-DV (Evolution Data/Voice)
    • Data rates:
      • Forward link - 3.1Mbps.
      • Reverse link - 1.8Mbps.
    • Encoding technique:
      • Forward link – 16QAM.
      • Reverse link - QPSK and 8PSK.
  • 32. EVDO Rev B
    • Combine up to fifteen 1.25MHz carriers (20MHz) in forward and/or reverse link. Carriers not physically combined and not adjacent to each other.
    • Data rate:
      • Forward link = 3.1Mbps*15channels = 47Mbps.
      • Reverse link = 1.8Mbps*15channels = 27Mbps.
    • Encoding technique 64QAM. Uplink data rate increases from 3.1Mbps to 4.9Mbps per channel. Thus, Data rate:
      • Forward link = 4.9Mbps*15channels = 74Mbps.
    • Only software updation required.
