ON ROADThe major application of BANis to connect allwireless portabledevices locally toform a self-sufficient networkaround humanbody.

Devices within aBAN can then shareresources such asprocessing power,storage space andInternet

connectivity .

At WorkConnecting PC and CE products Integrating PC, communication and CE devices to make a more productive office

environment.Central devices: Office PC

Connection type: Mostly portable to stationary device

Examples: Use office PC as a gateway to allow portable devices to connect to the Internet; Connect your laptop PC to the projector in the meeting room; Connect your desktop telephone to your PC so that you can make and answer phone

calls using either device.For example, you find a contact in the address book in your PC. You click on the

contact, your phone then makes the call for you automatically.As another example, your phone rings while you are listening to the music. YourPC pop-up a window telling who is calling. Instead of picking up the phone, youanswer the call by clicking the button on your PC screen and using your headset.

You sync your Smartphone or PDA to your PC through BAN connection.

TECHNICAL REQUIREMENTS

There is no specific standard for BANs Current standards come close for specific use cases, not broad

enough Issues: power consumption, discovery, QoS

Support for very low power devices, sensors

Target less than 10% power consumption for communications comparedto total device

Have single standard with broad range of supported data rate -scalability

ISSUES

PRIVACY ISSUESAll communications overwireless networks and Internetare required to be encrypted toprotect the user's privacy. Somecountries have added this typeof clause in their existing legalacts or enacted new laws.It is also necessary that, specificusers should not be identifiedunless there is a need.

Another important measure isto create awareness in generalpublic. It can be extremelybeneficial if people are educatedregarding security and privacyissues and their Implications .

LEGAL ISSUES

As the data in wireless sensornetworks for healthcare systemswill be sent to different peopleat different places, legal issuesmust arise. The most naturalquestion is who will have theresponsibilities and liabilities for

the data collected from aperson .
