Bluetooth Overview

• Started as Ericsson Product Called MC-Link• SIG formed Oct. 1997, Ericsson, Nokia, Intel, IBM,

Toshiba• Official Announcement May 20, 1998• Presently over 1100 Adopters of the Technology• First Products Available 1H’00

Harald Blaatand (“Bluetooth”) II

• King of Denmark 940-981– Son of Gorm the Old

– Introduced Christianity to Viking World

– United all of Denmark and Norway

• This is one of two Runic stones he erected in his capitol city of Jellings (central Jutland)– This is the front of the stone depicting the chivalry of Harald.

– The stone’s inscription say:• Harald christianized the Danes

• Harald controlled Denmark and Norway

• Harald thinks notebooks and cellular phones should be seamlessly connected

Bluetooth Program

• Bluetooth is a cable replacement with seamless interoperability between devices– Goes where users go (global use, 2.4 GHz ISM Band)– Short range, low cost, low power

• Huge interest/acceptance of Bluetooth with > 1100 adopters of the technology today– IP open space specification– IBM, Toshiba, Ericsson, Nokia, Motorola, Qualcomm,

HP, 3Com, Dell, Compaq, Sony, Saab, NTT DoCoMo– Everyone feels that they can play, with huge potential

volumes

Bluetooth is a Cable Replacement

• Problem Bluetooth Solves:– Too many wires and connectors– Portable devices don’t work well together– No “anywhere” seamless connectivity

Bluetooth Radio Characteristics

• Fast Frequency Hopping Spread Spectrum System– 1600 Hops per second

– Hops over 79 MHz bandwidth (2.402-2.480 GHz)

– 1 MHz Channel Width

– 1 MS/s Air Data Rate

– Asymmetrical 720K bps, 56K bps

– Symmetrical 432K bps each direction

6/8/99 9

Program Status

• The Bluetooth SIG published revision 1.0 of the Specification in July

• Product announcements will began at Telecom ’99• Consumer products available 1H’00• Many different product types will be available at

product introduction

6/8/99 10

Frequency Harmonization

• Three main focus geographies: US, Europe, Japan– US – FCC – Concept approved, waiting for formal

submittals

– Europe – R&TTE – Rules in effect 4/00. The Bluetooth SIG will file in individual countries

– Japan – MPT/JATE – Proposal before Diet, laws changing to allow Bluetooth operation

• Other countries around the world will be contacted starting in August

6/8/99 11

Airline Regulatory Activities

• Key Messages

• Globalization

• EMI Analysis

• Bluetooth Regulatory Testing

• Avionics Compatibility Plans

6/8/99 12

Key Messages

• The Bluetooth SIG is working with regulatory bodies (FAA, JAA) and airlines worldwide to develop a compliant solution.

• The RTCA report RTCA/DO-233 will be used as a basis for EMI testing, and EMC analysis.

• Intend to work with airline industry to perform ground based and in-flight aircraft testing of Bluetooth systems.

6/8/99 13

Globalization

• Initial regulatory activities focused on the following geographies:

– North America (FAA [RTCA], FCC [part 15, …])

– EU (ETSI, [EN300-440, ETS 300-342, 300-328, …])

– Japan (MPT/JATE)

• Bluetooth SIG has engaged a multi-national certification company to address/define country specific regulations. (Data on 110 countries)

6/8/99 14

EMI Analysis

• Bluetooth SIG has hired a former RTCA and PED committee member as a consultant to:

– Develop a Bluetooth EMI profile model.

– Evaluate the EMI profile against the RTCA developed models, to identify possible areas of further investigation.

– Evaluate Bluetooth’s interaction with specific aircraft subsystems (i.e. GPS, navigation).

– Develop aircraft compatibility Test procedures.

6/8/99 15

Bluetooth Regulatory Testing

• The Bluetooth SIG will have complete EMI data taken on Bluetooth modules in accordance with the RTCA DO-233 methods. Done - August ‘99

• Multiple certification test companies will take independent data to ensure comprehensive testing has occurred

• FCC, and ETSI certificates will be provided for each module user.

6/8/99 16

Avionics Compatibility Plans

• The Bluetooth SIG is working closely with the Aviation and Airline Industry to test/evaluate Bluetooth Systems on ground and in-flight based aircraft.

• Test methodology will provide empirical validation of safety margins.

• Results will allow extrapolation to other aircraft types and other aircraft systems.

6/8/99 17

Work with the FAA

• Presently working with the FAA to evaluate propagation characteristics at 2.4GHz on aircraft– Study Includes: In-Cabin propagation and baggage to

cabin path loss data

• Report to be published on the Bluetooth Web Site

6/8/99 18

Objectives of FAA Test

• Assess Propagation Loss at 2.45 GHz

• Assess Polarization Loss

• Assess Multipath Fading

• Use results to evaluate Bluetooth performance in Aircraft

• Use results to compare Bluetooth with PEDs

6/8/99 19

Bluetooth Performance

• Losses comparable to free space

• Minimal screening by cabin furniture

• Cabin wide communications at 0 dBm

• 80% of hops unfaded
