2. 15.11.20152 Agenda Multipath communication systems CALM system DOTEK Parameters Applications Architecture Usecase Implementation Summary Demonstration

3. 15.11.20153 Multipath communication systems

4. 15.11.20154 CALM ISO TC204, WG16.1 – „Communications Air-interface for Long and Medium range” Concept of complex standards identification the best available wireless access soution in given time and area CALM standards have implemented Policy- Based Management (PBM) approach. Handover in CALM is implemented on the L2 of the TCP/IP model.

5. 15.11.20155 DOTEK Project of the communication module for transport telematics CALM-based system with handover on L3 with available technologies Selects optimal (best) available access network according to required parameters It increases the value of important performance parameters Parameters: Actual measured parameters (latency, packet loss, SNR,…) Statistic parameters (MTBF, MTTR, availability, reliability,…) Static parameters (security level, price,…)

6. 15.11.20156 DOTEK Telematic applications Fleet management systems System for electronic fee collection (EFC) Vehicle systems for communication with other vehicles and infrastructure (C2X) Systems complemented satellite navigation services Systems for Emergency call (eCall) Communication technologies GSM (GPRS, EDGE), UMTS, WiMAX, WiFi, Bluetooth, MBWA, UWB, RFID, DSRC, ZigBee, IR

7. 15.11.20157 DOTEK Architecture Management Monitoring – SNR, latency, packet loss Decision – price vs. quality Handover – L3 instead of L2

8. 15.11.20158 DOTEK Architecture Management Monitoring – SNR, latency, packet loss Decision – price vs. quality Handover – L3 instead of L2

9. 15.11.20159 DOTEK Architecture Management Monitoring – SNR, latency, packet loss Decision – price vs. quality Handover – L3 instead of L2
