Property of the Home. RF Working Group What is Home. RF? Description: Home. RF blends several technologies to extend beyond office WLAN solutions, making it the preferred wireless technology for homes and small offices with no network administrator. The open Home. RF specification is designed and optimized for consumer households, is ideal for broadband, and enables digital convergence with support for voice, music, TV, gaming, and data applications. Home. RF is important because telephone and entertainment devices can benefit from networks just as much as PCs.

Property of the Home. RF Working Group is Simple (Fast and Cheap to Install) Wireless offers Convenience and sometimes is the only way to network. • • • No holes to drill or cables to pull • Potentially eliminates Truck Roll Supplied S/W simplifies setup Put the Cable Modem or Set-Top Box by a TV and install Home. RF on PCs

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

Property of the Home. RF Working Group Extends beyond Wireless Ethernet Home. RF is a New Category

Property of the Home. RF Working Group Broadens the reach of DECT • Digital Enhanced Cordless Telephone (DECT) is the world’s most successful cordless standard. – Cordless Phone market is 10 x WLAN – > 50 M radios in 2000 alone – > 200 M DECT handsets in the field by 2003 – > 100 certified DECT suppliers, plus proprietary 2. 4 GHz • – 5 th generation silicon with complete chipsets << $10 1. 9 GHz DECT requires license outside of Europe – By using 2. 4 GHz, Home. RF moves DECT to worldwide markets as “Global DECT”

Property of the Home. RF Working Group Is Global DECT … PLUS • High-speed Data Networking • Entertainment Networking – – WLAN at Ethernet speeds Avoids security problems of Wi-Fi Excellent immunity to 2. 4 GHz interference Scales better than Wi-Fi (apartments, office parks) – Key Broadband apps – Internet Radio, TV and Gaming – Multimedia needs Qo. S and Interference Immunity Enables New Convergence Apps and Devices – – – PC enhances the phones – Phones enhance the PC Email notification on Phone – Caller ID on TV Unified Messaging – Video Phone Voice access to PC & Internet apps Adds Value and Improves Margins

Property of the Home. RF Working Group Sees Home Networking as MORE than a Wireless LAN • Cordless Phones • • • – 10 x larger market than Wireless LAN Entertainment – Internet Audio & Video are key broadband apps Shared Resources & Internet Access – Multi-PC and/or Broadband Households 9 M subscribers in 2001, growing to 40 M in 2005 Trend: Integrated Service Bundles Cordless Convergence without high prices – Combine Router, LAN access point, Voice base station, etc. – Both Phones and PC NICs under $100

Property of the Home. RF Working Group Sees Home Networking as Data Opportunity: • • 9 M US households with Broadband in 2001 – Going to 40 M broadband households in 2005 – 80% have access and 14% plan to upgrade w/i 12 months ~ 25% of Households will be networked by 2004 – 43% of broadband homes have >1 PC – 67% of BB multi-PC homes already have a home network Most networked homes use Ethernet – But 70% planning a home network prefer wireless > $4 B in home N/W equip. by 2005 (NICs, routers) – > $5 Billion in gateways, >10 B in info. appliances by 2005 – > $10 Billion/year in Internet access services today

Property of the Home. RF Working Group Sees Home Networking as Telephone Opportunity: • • • >95% of US homes have Telephone service – Voice is Key Application in Broadband Bundles – More revenue from Phone Features than from Internet Access Data Revenues are Rising but Voice Dominates – Vo. TDM (Voice over Time Division Multiplexing) is falling – Vo. IP (and Multi-line) is increasing Cordless phone market is ~10* wireless LAN – 43 M US cordless phones shipped in 2000 + 28 M DECT phones in Europe – ~50% of households buy a new cordless phone each year

Property of the Home. RF Working Group Sees Home Networking as Entertainment Opportunity: • • Internet Radio and Streaming Digital Music Wireless Speakers and Headphones Multi-player Gaming with Voice Video-on-demand, TV-based e-commerce, Voiceenhanced TV apps

Property of the Home. RF Working Group Sees Home Networking as Convergence Opportunity: • • • Home. RF is Ideal for Broadband – Enables integration of Voice, Data, and Entertainment – Enables new Apps, Devices, Services, and Margins Broadband growth slowing – Need less cost, more value, simplicity to cross Chasm – Connect PCs, TV, stereos, phones, etc. without Truck Roll Competition for Packaged Services – Consumers and service providers both benefit – 65% of PC households are comfortable with service bundles – Telcos need TV to complete the bundle, MSOs need Voice (a matter of survival)
