• Power-line networking is inexpensive method for connecting computers in different places in home or office

Power-Line NetworkingPower-Line Networking

Wireless NetworkingWireless Networking

• Creates network by sending infrared or radio signals between computers

• Better than Power-line networking; some computers are not “plugged in” to electrical outlet

• Laptop with wireless network card is completely portable throughout home or office

• IrDA (Infrared Direct Access) is standard for devices to communicate using infrared light pulses

• Infrared devices must be in direct line of sight with each other (like TV remote… which uses same infrared technology)

• Infrared is almost always “one to one” technology

• Radio signals better because no line of sight requirement and ability to broadcast to multiple recipients

Wireless NetworkingWireless Networking

BluetoothBluetooth• Bluetooth is new standard being developed

by a group of electronics manufacturers

• Will allow any sort of electronic equipment to communicate with each other

• Can be used among computers, keyboard, mouse, printer, headphone, cell phone

• Bluetooth-like radio communications should take place of wires or infrared signals for connecting devices

BluetoothBluetooth

• Wireless: No need for cables or cords to any device

• Inexpensive: Should add only about $5-10 to price of product

• Simple: Devices find one another and strike up conversation without any work on your part

• Why is it called Bluetooth?•Harald Bluetooth was king of Denmark

around the turn of the last millenium•He united Denmark and part of

Norway into a single kingdom

BluetoothBluetooth

• Satellite Internet access already commonplace

• Satellites orbit at several hundreds of miles above Earth

• Imagine airplane-like device at approximately 60,000 feet

• Aircraft will be undisturbed by inclement weather and will be flying well above commercial air traffic

Airborne InternetAirborne Internet

• All satellite benefits without some of the problems

• Consumers would get connections comparable to Digital Subscriber Line (DSL)

• High-speed wireless Internet connection by placing aircraft in fixed pattern over city

• Could be lightweight planes (possibly unmanned) or blimps


• Airborne Internet will function much like satellite-based Internet access, but without time delay

• Cost advantage over satellites – aircraft can be deployed easily – do not have to be launched into space

• Airborne Internet could even complement satellite and ground-based networks, not replace them


• Impact: Possibility of constant connection to network anywhere, any time

• Benefit: Ease of connecting all computers and related devices

• Challenges: How to make most efficient use of the computing power, software, and tools always available

to the point of need• All developments will eventually

become part of standard internet

Internet Protocol Version 6 (IPv6)


Today’s Internet uses Internet Protocol Version 4 (IPv4) – approximately 20 years old

Internet Protocol Version 6 (IPv6) (also called IPng) will eventually replace IPv4

• IPv6 fixes a number of problems in IPv4, such as limited number of available IPv4 addresses

• IPv6 goes from 32 to 128 bits per address

• If whole Earth was a beach, more than enough IP addresses for every grain of sand ... hope that will be enough

• IPv6 also routes messages better, auto-configures for missing computers, and includes security components for encryption and authentication
