2. Contents • Vision of VLC • Network Composition • Network Integration for Home Networks • Some Scenarios • Conclusion Yeong Min Jang, Kookmin University

3. Vision of VLC • Lack of radio resources in existing communication • Larger bandwidth than the current available radio frequency (about 300G Hz) • Harmless for human body( especially for eyes) and electronic devices • Short distance communication • Interference is controllable in the home environment • Power has not been limited • Less power consumption • Fluorescent bulb • LED Yeong Min Jang, Kookmin University

4. Goal of Home Network • Anytime, anywhere, anyone • Higher data rate support • 1Gbps for low mobility • True inter-system mobility management • Greater flexibility to support many different types of services simultaneously • All IP network Yeong Min Jang, Kookmin University

5. IMT-AdvancedNetwork Architecture VLC, Zigbee,… Yeong Min Jang, Kookmin University

6. Interconnected Cellular and VLC Networks • The advantages • Increasing coverage area • High data rate • Reuse of resources • Dynamic of wireless access • Challenges • No standardization • QoS control over heterogeneous services Yeong Min Jang, Kookmin University

7. What is Network Composition • New architecture to enable plug & play control-plane interworking as sharing of control among networks • Generic • The same operation can be used for interworking and sharing of any control functionality and different types of networks • Plug & play automatic operation without or minimal human interaction • Extendable • Easy extended to new type of control function • Adjustable operation • Controllable operation Yeong Min Jang, Kookmin University

8. Purpose and Benefits of Network Composition • Flexible and more dynamic cooperation of heterogeneous networks on the control plane • Cooperating between heterogeneous networks in a standardized way to save time and cost • Saving on transaction costs • Increase coverage, QoS and service availability to end-users • Seamless handover of user’s device with the best QoS on the move Yeong Min Jang, Kookmin University
