3 Mobile Service Force. Paper was a serious issue: Costing time and money. METTLER - TOLEDO Leading manufactures of scales and lab technology 300 technicians as field support in Germany > maintenance jobs annualy for each technician Paper forms very expensive Lengthy time between maintenance job and billing No customer data at customer s location available , Seite 3
4 Mobile Service Solutions. The Mettler Toledo Solution: Fully functional synchronisation client for Windows XP supporting online and offline usage Secure, encrypted synchronisation using different channels: W-LAN, GPRS, GSM, ISDN, Internet... Securing future adequateness by consequently using standards such as.net and XML Connecting ERP/CRM-backend-systems via XML-based command interface Digital forms for field service staff and customers including digital signature , Seite 4
5 Process Optimization for Mettler Toledo Field Service. Increasind field service efficiency and service quality by ommitting mediabarriers Windows XP synchronization, client fully functional in online and office mode Connection of any desired ERP/CRM system possible via XML command interface , Seite 5

Billions of hours being spent in bus/railway commute every year. 9.2 bill. rides p.a. in Germany Local Travel: Urban and suburban commuter 7.4 bill. rides p.a.,., thereof: bill.railway commuter (34%) bill. bus rides 422 Companies: Top 3.5 bill. Rides, 1.2 bill. on rail (16) Midrange City (66) Regional Travel: 1.7 bill. rides p.a. in trains 46 single companies of DB Regio AG Market share DB Regio: 91.8 % - Others: Rhenus Keolis, Connex (8.2%) Long Distance Travel: 0.12 bill. rides in long distance trains (ICE, EC / IC) Market share DB Reise und Touristik: : 100% Average travel time: 10 min. Out of scope Small-City / Region (ca. 340) Average travel time: 30 min. Average travel time: 120 min. Local and regional bus travel: Not feasible for Broadwave infrastructure Transportation in taxis and (rental) cars: Not feasible for Broadwave infrastructure Source: Project team and HD Market Consult , Seite 6
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
9 Local public passenger transport. Demonstrator for vehicles in local/regional public passenger transport. Installation within the train WLAN antenna Server underneath a passenger seat WLAN access points mounted in an overhead space , Seite 9
10 Local public passenger transport. Demonstrator for vehicles in local/regional public passenger transport. WLAN backbone installation Left: WLAN Bridge with antennas at entrance of tunnel Right: Backbone switch in OTN cabinet Left: WLAN bridge with antennas at Deutsche Telekom Right: WLAN bridge with antennas in Siegburg , Seite 10
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
