Intro We are not suppose to build the world class measurement system September 2003 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 Hasse Sinivaara, Nokia
Current TGk draft “holes” September 2003 Information for Passively Scanning terminals is missing From Terminal point of view Nokia see that getting information by listening only is very important Hasse Sinivaara, Nokia
Nokia Interests Getting information by listening only September 2003 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 Hasse Sinivaara, Nokia
Nokia interest, cont. ESS boundary September 2003 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 Hasse Sinivaara, Nokia
Implementation concerns September 2003 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 Hasse Sinivaara, Nokia
