7 Always Best Connected. Demonstrator for vehicles in local/regional public passenger transport. Technical field trial in conjunction with local transportation company Stadtwerke Bonn (SWB) Goal Extended technical trial to gain experience in local public transportation environment Status of cooperation Trial started in December Dec One train at Line 66 Telekom Express to be equipped with BroadWave gateway/server Only friendly users from DTAG and SWB Trial was shown on the IPK Services to be provided in the first trial phase Interface to user by welcome page in T-Com T HotSpot style Local content (information, music, videos, ) Internet access after authentication using the different access networks (WLAN, GPRS/UMTS) Update of local content at selected WLAN data filling stations Service extensions planned after March , Seite 7

8 Local public passenger transport. Demonstrator for vehicles in local/regional public passenger transport. Technical field trial in conjunction with local transportation company Stadtwerke Bonn (SWB) Technical details on access network WLAN coverage at 6 stations (continuous coverage along 5 stops) Use of SWB fiber network as WLAN backbone Additonal radio link via GPRS/UMTS (seamless handover with WLAN) WLAN WLAN GPRS and UMTS Seamless Roaming SWB fiber network Internet DTAG data center WLAN coverage , Seite 8

11 Always Best Connected. Solution for high speed trains will be tested in field trial soon. Radio system evaluation and channel measurements Radio channel measurements along ICE railway tracks Nearly no results available about the radio channel in a typical train environment which consists of many metal poles and electrical lines nearby the train antenna Old results from GSM/GSM-R R measurements (narrow bandwidth) New results only from the satellite-train train radio channel (Ku band) Knowledge of radio wave propagation environment as precondition for realistic system evaluation System performance at high speed strongly dependent on channel characteristic (result of lab tests) WLAN on-train coverage measurement Detailed measurement of radio coverage achievable within ICE-3 3 trains by WLAN access points (access and backbone) Computation of interference scenarios at changes of frequency channels , Seite 11
