intro
Intro
  • We are not suppose to build the world class measurement system
  • Careful analysis of What is practical value of any “new measurement”
  • Requirement in implementation complexity for various requirements in TGk
  • Applications in High Level perspective
    • System Monitoring (+configuration/parametrization) OR
    • Active functions (e.g. Intra system/Inter system Handover)
  • Current TGk draft is containing mostly Active Scanning based information

Current TGk draft “holes”
  • Information for Passively Scanning terminals is missing
  • From Terminal point of view Nokia see that getting information by listening only is very important

Nokia Interests
  • Getting information by listening only
  • Site Reporting, Load information in Beacon
  • Practical Value:
    • More effective HO algorithms and AP selection algorithms can be build for multiradio terminals
    • Information is more critical for Cellular-WLAN Multiradio terminals

Nokia interest, cont.
  • ESS boundary
    • Simple bit in beacon telling whether AP is “gateway” or not
    • Practical Value:
      • Cellular-WLAN multiradio terminals able to detect which cells are the most optimum to perform Handover and where those “spots” are
      • Helps the AP to guide the terminal into correct cell, can be used to trigger the WLAN-to-Cellular HO as well
      • minimising the spurious HO’s between WLAN/Cellular if the WLAN system has coverage holes

implementation concerns
Implementation concerns
  • Most crucial is that the implementation complexity stays low
  • PSNI/EVM/RCPI in practise:
    • PSNI has to be taken into account in the WLAN chip design as a specific implementation
    • Tight Accuracy in PSNI/EVM/RCPI requires one-by-one calibration for 802.11 Type2 devices
