  3. Introduction • Motivation: Real-time traffic reporting system with vehicular communication could be greatly improved when using LTE. • Using 2G/3G cellular network may counter: • Long end-to-end delay • Disconnect when moving fast • The new traffic reporting system takes the advantages of m2m communication and LTE network. • Increasing data rate • Higher mobility • Reporting real-time data like images or video from • Cars • Roadside units

  4. Background • M2M – Machine-to-Machine: Devices can communicate with each other. • Machine Type Communication (MTC) / Information of Things (IoT) • All machines connected to Internet • Heterogeneous network • LTE • MIMO (Supporting Diversity and Multiplexing) • High data rate (Downlink up to 300Mbps) • Mobility (Up to 350 km/hr) • M2M over LTE: Devices connect to Internet via LTE. • Directly connect • MTCGW – MTC Gateway • Pros • Mobility • Lower construction cost • Challenges • Different QoS requirements • Resource allocation • Fairness among devices/users

  5. Issue • To satisfy all users with different QoSlevels, and reach the maximum possible spectrum efficiency, there are many aspects to concern: • QoS Levels: • Different types of vehicles and data • Location • Instant Channel Quality • Which channel conditions to take are decided by what kind of network the devices used. • Adaptive MIMO Switching (AMS)
