LIVES !!!THRIVES !

• Wiring History: Slow Evolution vs. PC / NW

• Old House Retrofit: Electricity, Gas, Water, Phone, Cable (all physical extensions)

• New House Retrofit: Concrete slab, Two-story, Fire blocks, Conduit, New tools

• MDU Retrofit: Easier Justification

A Personal Wiring Experience

• 8 Years Ago versus Today – Home-run, Cat.5, RG6– Twisted arm, Wiring mistakes, Trim carpenters,

Electric circuits– >12 Builders in Austin + 1 with Fiber

• Lifestyle Changes: Moved Home Office

• New Device types: WebTV, Surveillance Cameras, Sensors, Flat Panel Displays, Wireless Speakers, Cars

Innovation to the Rescue

• Market need = Opportunity = Technology

• New wire types: RG-59 /-6, Cat.5 /.5e /.6 /.7, Fiber???

• New Software: Digital Convergence, Compression, Encryption, Rights Management

• No-new-wires: Power lines, Phone lines, Wireless

• How much Bandwidth? Video-on-Demand

IBM System/370 model 158 (circa 1975)1 MIPS

Can you Future-Proof your Home?

The Embedded Mainframe

30 GHz, 600 GIPS15 GB (memory)22 TB (storage)1.2 Gbps (network)

The Handheld Mainframe

A/C Powered and Stationary

• Ordinary Devices get Networked– Everything with a Plug

• But Power Line is Electrically Noisy

• New Technologies: HomePlug

• Homes per Transformer

Battery Powered and Mobile

Data Comm

Entertainment

• Small & Battery Operated = Mobile– Everything with a battery gets networked– Sofa, Kitchen, Deck, Car, Public Places– Mobile = Wireless Wars ( ONE standard? )

• Wireless Issues– Throughput, Range, Attenuation, Interference, QoS,

Cost, Power Consumption, Latency, Scalability
