Aim
  • This presentation aims to analyze the confusion
    and over sayings surrounding the relative merits
    of various wireless broadband technologies like
    WiMAX, EDGE and get to the real reasons that will
    influence the success of mobile broadband and
    its ability to deliver broadband for all and
    everywhere.

  • Introduction
  • Adoption
  • Architecture of HSPA
  • Comparison with WiMAX

Introduction HSPA
  • HSPA, the undisputed choice for mobile
  • broadband
  • HSPA offers operators a single network for
    multiple services.
  • HSPA a state-of-the art technology.
  • HSUPA is to follow HSDPA
  • HSPAHSDPA HSUPA

HSDPA
  • High Speed Downlink Packet Access
  • High speed data enhancement for WCDMA/UMTS
  • Peak theoretical speeds of 14.4 Mbps
  • Current devices support 7.2 Mbps throughput
  • Methods used by HSDPA
  • Short transmission time interval (TTI)
  • Fast scheduling and user diversity
  • Higher-order modulation
  • Fast link adaptation
  • Fast hybrid automatic-repeat-request (HARQ)

7
HSUPA
  • High Speed Uplink Packet Access
  • 85 increase in overall cell throughput on the
    uplink
  • Achievable rates of 1 Mbps on the uplink
  • Reduced packet delays to as low as 30 msec
  • Methods used by HSUPA
  • An enhanced dedicated physical channel
  • A short TTI, as low as 2 msec, which allows
    faster responses to changing radio conditions and
    error conditions
  • Fast Hybrid ARQ, which improves the efficiency of
    error processing

EXPLANATION
  • HSPA is a Frequency Division Duplex (FDD)
    technology, in which the uplink and downlink are
    in separate frequency channels (usually denoted
    as 2x5MHz).
  • RNC- Radio Network controller
  • That is connected between Base Stations and Core
    Network.

COMPARISONS
  • HSPA is a Frequency Division Duplex (FDD)
    technology. Mobile WiMAX is a Time Division
    Duplex (TDD) technology,
  • uplink and downlink frequency channels

HSPA
  • HSPA Objectives
  • Achieve performance close to LTE in 5 MHz of
    spectrum.
  • Provide smooth internetworking between HSPA and
    LTE, thereby facilitating the operation of both
    technologies.
  • Allow operation in a packet-only mode for both
    voice and data.
  • Facilitate migration from current HSPA
    infrastructure to HSPA infrastructure.

FUTURE PERSPECTIVE
  • However, HSPA is only one step in the evolution
    of mobile broadband.
  • Delivering peak rates of 14Mbps in the downlink
    and 5.8Mbps in the uplink today, its evolution
    adds support for MIMO and 64QAM that will deliver
    42Mbps in the downlink and 11.5Mbps in the
    uplink.
  • In parallel, LTE will deliver further
    enhancements in peak rates (exceeding 100Mbps),
    in addition to scalable channel bandwidths using
    OFDMA with both TDD and FDD operation. LTE and
    HSPA-evolved offer maximum spectrum flexibility
    while delivering true high-speed, high-quality 4G
    performance.

21
CONCLUSION
  • HSPA is the undisputed leader in mobile broadband
    services covering both traditional mobile
    terminals and personal consumer devices such as
    notebooks, ultra mobile PCs, cameras, portable
    game consoles and music players
  • Economically viable and affordable with respect
    to rest of Gadgets of ecosystem.
  • Ever-improving performance, with
    commercially-proven transmission bit-rates of up
    to 14Mbps today and up to 42Mbps in the near
    future
  • highly economic urban and rural coverage, with up
    to 200km cell range and measured speeds in excess
    of 2Mbps at the cell border

22
  • HSPA is a clearly defined and easily adopted
    evolution path.
