What is HomeRF?
Description:
HomeRF 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 HomeRF 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.
HomeRF is important because telephone and entertainment
devices can benefit from networks just as much as PCs.
Property of the HomeRF Working Group
is Simple (Fast and Cheap to Install)
Wireless offers Convenience and sometimes is the
only way to network.

Broadens the reach of DECT
•
Digital Enhanced Cordless Telephone (DECT) is
the world’s most successful cordless standard.
– Cordless Phone market is 10x WLAN
– > 50M radios in 2000 alone
– > 200M DECT handsets in the field by 2003
– > 100 certified DECT suppliers, plus proprietary 2.4 GHz
•
– 5th generation silicon with complete chipsets << $10
1.9 GHz DECT requires license outside of Europe
– By using 2.4 GHz, HomeRF moves DECT to
worldwide markets as “Global DECT”
Property of the HomeRF Working Group
Is Global DECT … PLUS

Sees Home Networking as
MORE than a Wireless LAN
• Cordless Phones
•
•
•
– 10x larger market than Wireless LAN
Entertainment
– Internet Audio & Video are key broadband apps
Shared Resources & Internet Access
– Multi-PC and/or Broadband Households
9M subscribers in 2001, growing to 40M 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

Sees Home Networking as
Data Opportunity:
•
•
•
•
9M US households with Broadband in 2001
– Going to 40M 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
> $4B in home N/W equip. by 2005 (NICs, routers)
– > $5 Billion in gateways, >10B in info.appliances by 2005
– > $10 Billion/year in Internet access services today
Property of the HomeRF 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
– VoTDM (Voice over Time Division Multiplexing) is falling
– VoIP (and Multi-line) is increasing
Cordless phone market is ~10* wireless LAN
– 43M US cordless phones shipped in 2000 + 28M DECT
phones in Europe
– ~50% of households buy a new cordless phone each year
Property of the HomeRF Working Group
Sees Home Networking as
Entertainment Opportunity:
•
•
•
•
Internet Radio and Streaming Digital Music

Convergence Opportunity:
•
•
•
HomeRF 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)
