What comes next?
What Consumers Are
Demanding Today

Engaging Internet content and services
throughout their home


At faster than 56K speeds
Peripheral sharing between different PCs

Printers, files
“I like the Internet sharing so I don’t have to
get a divorce. You know, we’re killing each
other [over access].”
- Houston focus group respondent
Consumers Demand
Broadband
Internet has become #1 reason for new PC purchase


Internet-based from stand-alone PC activities
Current speeds limit usefulness
80% are willing to pay for high-speed access
(Parks Associates Survey, 10/98)



$39-$49/month target acceptable
High-speed access: key enabler
to fully integrate into home lifestyle
Truly useful higher speed Internet
requires new digital infrastructure

Consumers Demand Sharing

12-15 million multiple PC families today, worldwide *


Home Internet access mostly during
evenings and weekends



When family members are home together
Creates need for shared access in multiple PC homes
Today’s solutions for Internet access conflict



Annual growth rate of about 30% = 25+ million by 2001!
Multiple phone lines and ISP accounts
Time sharing with single line and account
Broadband complicates the contention problem


Cable and full rate ADSL drops accessible to only one machine
Splitterless ADSL (G.Lite) requires multiple modems
 Like normal modems, doesn’t resolve contention
Tangible consumer needs are here now. Fortunately, so are
the home networking technologies to meet them




Standard network media, without rewiring



HomePNA phone line here now for 1999 products
HomeRF wireless an option for 2000


OEM enhancement, without
jeopardizing interoperability
Standard Broadband
PC integration will drive proliferation

Standard technologies ramping up in 1999




Internal partitioning options, e.g., on PCI




G.Lite: splitter-less ADSL, up to 1.5 Mbps downstream
 Lowest support option
G.DMT: splitter-based ADSL, up to six
Mbps downstream
 Requires phone company installation
Cable modem (DOCSIS)
DSL only modem: G.Lite, G.DMT, or both
DSL + V.90 modem
DSL/V.90 modem + phone line network
Preferred external connection: USB


For Plug and Play installation and configuration
10baseT will require more configuration support
Standard Phoneline

Network Alliance
First home connectivity cornerstone
 1998 accomplishments
 Announced formation June 22, 1998, 11 Founding Members
 Increased membership to nearly four times size since
incorporation (September 1998)
 Endorsed, field tested, and solidified base 1 Mbit/s technology
 Published HomePNA V1.0 specification
 Established Independent Interoperability and Certification
test lab (CIC PlugLab)
 1999 objectives
 Establish 10 Mbit/s home phoneline networking specification
 Continue membership growth and engagement
 Increase public awareness of home phoneline
networking options

Field Test Introduction

HomePNA Field Test Overview
 500 Homes tested 9/98-11/98
 North East, North West, Mid-West, Southwest, West Coast
 Single family, Multi-Family, 90+ yrs old and newer dwellings
 Field test units implemented HomePNA Phy
 6 hour duration, packet send/receive loop
 Primarily targetted 6pm-midnight
 Prime Time for activity in the home and projected for home network use

Measurement Criteria and Baseline Measures
 Selected based on direct relevance to Consumer Experience
 Maintain Network Link
 Packet Error Rate
 Based on measurements on a TCP/IP over Ethernet Link
 1% or less PER translates into no noticeable degradation (900kbps at the
application level) and robust link
 less than 10% PER translates into up to 40% degradation (550kbps+ at the
application level) and robust link
 10% or greater PER translates into unacceptable performance
characteristics

Field Test Results


98%+ Homes Successfully Passed
 88% of homes reported 1% PER or less and maintained Link
 >10% of homes ran with less than 10% PER and maintained Link
 <2% of homes ran with 10% or greater PER
Homes with >1% PER were analyzed
 Root Cause
 Induced noise directly from telephony devices attached very near the
HomePNA test unit or via coupling of AC line through powered
telephony devices
 Signal Attenuation theorized as attenuation due to wire taps
 Both problems eliminated by introducing low pass filter between
offending device and wall outlet
 Frequency to be filtered out is >600Khz
 Covers both voice band (V.90) through G.Lite

Other observed interactions - low pass filter resolves
 Few reports of audible hiss in home telephones
 Some models of V.90 modems experience performance degradation when
sharing same wall outlet with HomePNA device
Implementing HomePNA

On system board



On PCI or Cardbus adapter






Requires silicon, magnetics, and RJ-11 connector
Lowers cost, keeps slot free
Options: stand-alone, 10baseT combo, V.90 combo
Avoids system board homologation
Easier to isolate signals from system board and
power supply noise
Combo 10baseT card can use existing MAC
Frees system board space, but uses slot
Use shared RJ-11 port with modem


Multiple ports a usability problem
Reduces connector space requirement
Standard Internet Sharing
Arriving in Windows releases this year

Microsoft Internet Connection Sharing (ICS):




Network Address Translation (NAT) based
 Most efficient method for simple translation
Standard address allocation
 DHCP services for connected networks
Standard name resolution
 DNS services
Supports Windows and non-Windows clients
 Compatible with any IP attached device
Adding To Internet Sharing
Building value-add applications

Develop application extensions



Leverage ICS APIs
Complement and enhance OSR functionality
 Remote monitoring/control of Internet Session
 Automated resource sharing
 Monitoring of Internet traffic
Set specific guidelines for your ISVs

Requires well behaved applications
 Avoid reserving IP ports
 Avoid using client IP address in application flows
Home Networking Setup
Making it easy for the user

Pre-install and configure hardware on gateway


Offer consumers easy way to install home
networking on client PCs



Include appropriate drivers and other components
