Bluetooth : Abstract

Bluetooth Idea :

*The need to interconnect computer and peripherals, handheld devices, PDAs, cell phones – replacement of IrDA led to the emergence of personal area networks (PANs)

*Universal radio interface for ad-hoc wireless connectivity

*Embedded in other devices, goal: $5/device (2005: $40 bluetooth headset)

*Short range (10 m), low power consumption, license-free 2.45 GHz ISM

*Voice and data transmission, approx. 1 Mbit/s gross data rate

Bluetooth Overview :

*Short range (10 m)

*Low power consumption

*2.4 GHz (Unlicensed ISM Band)

*Advantage: worldwide availability

*Disadvantage:

-interfere with IEEE 802.11b products
-Voice and data transmission, totally 1 Mbps
-Low cost
-less than US$5 for a Bluetooth chip
-Universal short-range wireless capability
-Available globally for unlicensed users
-Devices within 10 m can share up to 720 kbps of capacity
-Supports open-ended list of applications
-Data, audio, graphics, video

Bluetooth Application Areas :

*Data and voice access points

*Real-time voice and data transmissions

*Cable replacement

*Eliminates need for numerous cable attachments for connection

*Ad hoc networking

*Device with Bluetooth radio can establish connection with another when in range
