  1. Mesh networks for home entertainment Guido R. Hiertz, Yunpeng Zang ComNets Chair of Communication Networks Aachen University Germany Jörg Habetha Philips Research Aachen Germany Guido R. Hiertz, ComNets, Aachen University

  2. Television set DVD/CD Player/Recorder Wireless active speakers Surround sound Home Cinema/Theatre Remote control Game console Radio tuner (digital/analog) Satellite receiver (digital/analog) MP3 Computer as source CE device as source Wireless phones VoIP Consumer electronics (CE) Guido R. Hiertz, ComNets, Aachen University

  3. Video Video telephony not widely accepted Mainly streaming Mainly non-interactive High Definition TV Game console Audio Music/Sound streams Surround Telephony (VoIP) Control Channel selection Volume, etc. Classification from user view Guido R. Hiertz, ComNets, Aachen University

  4. Video display devices TV set CRT LCD Plasma Video projector LCD LCOS Mounted above head Video source devices VCR Camcorder DVD Set top box Satellite receiver Streaming server Video provider Video devices Guido R. Hiertz, ComNets, Aachen University

  5. Simplex source Radio (satellite/terrestrial) CD/DVD MP3 Simplex sink Active speakers Headset Duplex devices Wireless phone VoIP In house communication Audio devices Guido R. Hiertz, ComNets, Aachen University

  6. Game console • Combines Video and Audio signal • Rendered on your PC • Displayed somewhere else • Surround sound created on PC • Sound played back at game console • Control channel • Human Interface Devices (HID) • Joystick etc. Guido R. Hiertz, ComNets, Aachen University

  7. Requirements to CE • Ease of use • No user configuration • Support well known behavior of CE devices • Limit functionality to useful subset • No flaws on QoS tolerated  Competition to existing Audio/Video broadcast systems Guido R. Hiertz, ComNets, Aachen University

  8. Home environment (1) • Many stationary devices • Consumer electronic device always powered • Few mobile devices • Tablet PC • PDA • VoIP phone • Slow mobility • Very slow changing environment Guido R. Hiertz, ComNets, Aachen University

  9. Home environment (2) • Single household • Single Basic Service Set • Single administrative instance • Multiple apartments in shared environment • Multiple households • Self organizing MAC needed • Competition among neighbors on wireless medium Guido R. Hiertz, ComNets, Aachen University

  10. Home environment (3) Guido R. Hiertz, ComNets, Aachen University

  11. Home environment (3) Guido R. Hiertz, ComNets, Aachen University

  12. Mobility support Guido R. Hiertz, ComNets, Aachen University

  13. Multi Hop • Installation of multiple APs not possible • Women's acceptance factor • Device mesh network • Attenuation by walls • High for 802.11a (5GHz) • Reduce transmission power to reduce exposition to human beings  Multi hop capability needed Guido R. Hiertz, ComNets, Aachen University

  14. Multiple transceiver solutions Frequency diversity Easy spatial frequency reuse May set up separate backbone Parallel transmissions possible Single transceiver solutions Cheap Sufficient for average user (?) Avoid unused TRx Easy integration to CE CE is sensitive to cost Guido R. Hiertz, ComNets, Aachen University

  15. WPAN 802.15.3 • Various submissions regarding CE • Consumer electronic industry requirements for TG3a alt PHY (802.15-03/276r0) • Application of mmW-based PHYs (802.15-03/474r2) Guido R. Hiertz, ComNets, Aachen University
