Introduction

• The radio access network for B3G may be
  various,but some common characters should be
  contained
• Adapting to kinds of multiple accesses (e.g.
  IMT-2000, Wi-Fi and WiMAX).
• Superior wireless coverage and capacity
• Flexible application for all kinds of radio
  environment
• Agile configuration and adjustable structure by
  software can meet various services, which makes
  the heavy network planning easier.
• Resource management is more convenient.

Architecture of mobile wireless network

In this mobile wireless network, radio access
network mean the traditional cellular mobile
wireless network or distributed mobile wireless
network .

Abstract

• Traditional cellular network mobile wireless and
  distributed mobile wireless network have been
  concerned as main radio access technique of B3G
  system recently.
• These two kinds of technique have their
  advantages for response to different environment.
• According to the requirement of recommendation
  ITU-R M.1035,radio environment can be divided
  into macro,micro and pico cells.
• Based on this definition,several kinds of
  application about radio access network for B3G is
  described as follows

5
Radio access network for macro cell

• Mainly refers to Rural
• Largely coverage,1000mltrlt35km
• Less building and less shading
• Easy to install antenna on higher point to meet
  coverage
• The number of UE is fewer
• Single UEs throughput is various,
  voice,internet, IP TV,remote medical,remote
  teaching, ect..
• Traditional cellular beam forming is better

Radio access network for micro cell

• Mainly refers to Sub-Urban or Urban
• Geography and radio environment is complex
• Building shading is severe
• It is difficult to choose higher point to install
  antenna for meeting all coverage .
• Connecting fiber or coaxial line is relatively
  easy.
• Distributed radio access network antenna
  selecting is better

Radio access network for pico cell (general)

• Here the general pico cell refers to public
  inhabit community,hotel,business area,etc.
• The number of UR is more.
• The total throughput is more, but varying lower.
• Laying fiber or coaxial line is relatively easy.
• The UEs requirement for QoS is not high
• Distributed radio access network antenna
  selecting is better

Radio access network for pico cell(hot spot)

• Here the hot spot main refers to meeting
  room,commercial entertainment location,
  gymnasium, etc
• Most of it focus on indoor site, connecting with
  fiber or coaxial line is easy.
• Radio environment is not complex
• The total throughput is more, and varying higher
• The UEs requirement for QoS is high
• Distributed radio access network generalized
  MIMO is better.

conclusion

• Here several kinds of radio access network and
  their application for B3G is given,summarized as
  below
• Macro cell traditional cellular beam forming
  is better
• Micro cell distributed radio access network
  antenna selecting is better
• pico cell(general) distributed radio access
  network antenna selecting is better
• pico cell(hot spot) distributed radio access
  network generalized MIMO is better.
