  7. Broadband Home needs Information, Communications, Entertainment POTS ISDN xDSL Cable Property of the HomeRF Working Group

  8. PC Services on Handset Display PC controls thehandset display, receives all key presses. First Step: Text menus Text display Next Steps: Scripting Extensions UPnP Proxy SDK Speech recognition Text-to-Speech Property of the HomeRF Working Group

  9. (QoS, Latency) (QoS) (QoS) (QoS) Bandwidth Requirements Property of the HomeRF Working Group

  10. HomeRF 2.0 Capabilities • Data networking based on 802.11 FH • Ethernet speeds – 10 Mb/s peak data rate with fallback modes of 5 Mb/s, 1.6 Mb/s and 0.8 Mb/s • Voice support based on DECT • Up to 8 simultaneous toll-quality cordless voice connections • Cordless phones outsell WLAN devices 50:1 • Consumer voice revenues are 10X data revenues • Entertainment support via QoS • Internet audio and video are key apps for broadband • Up to 8 simultaneous prioritized streaming media sessions for audio and video • Powerful and effective security measures • Resists eavesdropping, service denial, unauthorized access • Active interference avoidance techniques • Bluetooth, cordless phones, microwave ovens, adjacent N/Ws Property of the HomeRF Working Group

  11. Internet HomeRF Capabilities Roadmap Enhanced Video Voice/Audio Basic Video Data • Video Tablets • Set Top Boxes • Gateways • Music Devices • Web Tablets • Cordless Phones 2000 2001 2002/3 1.6 Mb/s 10 Mb/s 25+ Mb/s Property of the HomeRF Working Group

  12. Growing Community of Products … for Voice, Data, Entertainment Applications USB Adapters (Desktop PCs) PC Cards (Notebook PCs) Compact Flash (PDAs, HPCs) Web Tablets Home Gateways Cable Modems DSL Modems STB & Video Products Automotive Products Music Products Phone Products Home Robots and More …

  13. Existing Upper Layers UDP TCP DECT IP HomeRF MAC Layer Priority CSMA TDMA CSMA/CA HomeRF PHY Layer “Ethernet” Data Path Toll-Quality Voice Path Streaming Media Path Network Layer View Property of the HomeRF Working Group

  14. Wireless Choices for the Broadband Internet home ATTRIBUTE HomeRF Bluetooth 802.11b Cost  ~   Security  ~ X Interference Immunity   X ~ Toll-Quality Voice Support  ~ X Streaming Media Support  ~ X ~ Data Throughput  X  Range  X  Power Consumption   X ~ Form Factor   X ~ Network Topology  ~ ~ Roaming Outside the Home ~ ~ ~ ~- Adequate X- Disadvantage - Advantage Legend: Property of the HomeRF Working Group

  15. 300’ 0’ 50’ 90’ 130’ ~5 Mbps Throughput ~2.5 Mbps ~1 Mbps ~0.5 Mbps RANGE: Signal Strength Diminishes with Distance 1 Mbps 2 Mbps 5 Mbps Advertised Data Rate: 11 Mbps

  16. MPEG2 Video Broadband/ MPG 4 Video Dial-up / MP3 Audio 802.11b HRF 2.0 PERFORMANCE over DistanceHomeRF 2.0 vs. 802.11b HomeRF provides real-time media streaming to more nodes over a greater distance. 6 5 4 Nominal throughput (Mbps) 3 2 1 0 10' 20' 30' 40' 50' 60' 70' 80' 90' 100' 110' 120' 130' 140' 150' Source: Practical and Theoretical Calculations Property of the HomeRF Working Group

  17. The Higher the Frequency, the more signal loss.5 GHz is worse than 2.4 GHz. ATTENUATION: Signal Strength Diminishes through Materials Wood and plaster Walls or Floors are OK. Even Brick. BUILDING WALL Metal and thick rock block the RF signals. Property of the HomeRF Working Group

  18. SECURITY: HomeRF Does Not Compromise it … Like Wi-Fi Does BUILDING WALL Trivial task to bypass Wi-Fi security w/ standard products

  19. INTERFERENCE: HomeRF hops around it FHSS DSSS Frequency Time Time IEEE 802.11b waits for Interference to go away Property of the HomeRF Working Group

  20. Re-Transmit Voice Calls Hop 2 1 Priority Streams Within data networking time, streaming media sessions get priority access If voice packets fail, they can be re-transmitted at the start of the next frequency Reserved time period based on number of active voice calls MAC Layer Basics Bulk of time is allocated to data networking time Data Networking Property of the HomeRF Working Group
