Bluetooth History

1994: Bluetooth is defined by Ericcson.

1998: Ericcson, IBM, Intel, Nokia, and Toshiba formed

Bluetooth SIG (Special Interest Group)

1999: The first Bluetooth consumer product, a hands-free

mobile.

2003: Each week more than 1 million Bluetooth-enabled

products were sold

2011: more then 3 billon Bluetooth-enabled products

and 14,000 BT SIG member.

2011: BT Version 4.0, Bluetooth low energy (BLE)


6

Bluetooth Technology

•Wireless audio, voice and data

• Personal Area Network {class 2(10m), class 1(100m)}

• Non license 2.4GHz ISM band

• Low power consumption (20-30mA for 115Kbps)

• Data rates (~1Kbps-2Mbps throughput)


7

Bluetooth Technology

• Frequency hopping spread-spectrum (79 channels)

• Piconet: one master and up to 7 slaves

• Scatternet: grid of piconet

• Placed almost in each mobile phone or laptop

• BT Profiles


8

BT common Profiles

• SPP Serial Port Profile

• HSP Hand Set Profile

• HFP Hand Free Profile

• A2DP Advance Audio Distributor Profile

• HID Human Interface Device Profile

• HDP Healthcare Device Profile

• DUN Dial Up Network Profile

• OPP Object Push Profile

Continua Alliance

Alliance for Leading Health and Medical Industry

Manufactures; Intel, Omron, Toshiba, Samsung, Philips,

Nokia, Dell, Motorola etc.

• Goal 1 - Promote new technologies for telemedical

solutions

• Goal 2 – set industry standards enabling interoperability

to facilitate faster market growth and time to

market


11

Continua motivation

• Requires wireless solutions for number of different

devices used for gathering data on weight, blood

pressure, glucose levels, temperature, heart rate,

cholesterol etc.

• USB for wired devices

• Bluetooth chosen as standard transport for wireless

devices

Bluetooth Low Energy

Bluetooth low energy is about

transferring state Small, infrequent

bits of data at lowest possible power

consumption at lowest latency

Bluetooth Low Energy


Low energy is coin cell batteries

15-20mA peak current

Low energy is years of life time
