What is BAN?

Wireless body area network (WBAN) or body sensor networ Is a wireless network of wearable computing devices

Formally defined by IEEE 802.15 as, a communication standoptimized for low power devices and operation on, in or arohuman body (but not limited to humans) to serve a variety o

applications including medical, consumer electronics / persoentertainment and other.

A typical body area network kit will consist of sensors, a proa transceiver and a battery.

BAN have grown as a refinement of body sensor network (BSN).

BSN devices< 0.01200 m

Human body itself can become channel for short range communthus removing the need for a traditional antenna

The power consumption of BSN devices shrinks to 0.1 - 1.0 mW

In this low power, the human body is capable to produce excess that the devices could scavenge the required energy directly frhosts body, thus removing the use of traditional power source, sbattery.

BSNmanaged body sensor networks (MBSN)

analyzed by the third party based on the data collected

autonomous body sensor networks (ABSN) attach actuators to the sensors to allow the BSN to effect change on the users

Literature Review Review of Body Area Network Technology & Wireless Med

Monitoring by Javed Ahmad and Fareeha ZafarWireless body area network is to remove all wire connecting the s

patient body and create wireless network between the sensors.

Measure blood pressure, oxygen saturation, sugar level and so on

Medical sensors, patient identifier and setup pen.

UWB Antennas in Body Area Networks by Hassan GhannuChristophe Roblin, and Serge Bories

Support short-range communication scenarios

Low power consumption

High data rate

Medical Application of Ultra Wideband by Jianli Pan

Federal Communications Commission (FCC) allowed the commercbandwidth

3.1GHz to 10.6GHz

UWB generated in a very short time period (sub-nano second)

Possible to get Gbps speed by using 10GHz spectrum

UWB has high gain which make it able to penetrate the wall

Low electromagnetic radiation

The design must consider of human body

Different thickness of tissue layer

Relative permitivity

Else cause pattern fragmentation, power absorption, anfrequency shift

Application(A) Smart Vest: Wearable multi-parameter remote physiological mosystem

- Smart vest is specially designed for certain professions such as sfighters, law enforcement personnel, miners, deep-sea divers and astro

- Monitor the health status and geo-location of the personnel to ensurand effective completion of the assigned job.

- It consists of shirt with embedded sensors which is the Smart Vacquisition and processing hardware with embedded software, wireless t

and a remote monitoring station to study the wearer's health.

- The Smart Vest system consists of sensors which are integrated for sephysiological data, wearable data acquisition and processing hardware (processed data are transmitted wireless) and a remote monitoring statithe data are received, analyzed and displayed).

- The sensors are connected by wires, which are woven or stitched into The sensors are placed at specific body locations and integrated into tthat it has good contact with the skin surface.

- Characteristics:

- The resistance of the wires = 0.3 /m

- Thickness of wire = 0.19 mm,

- Tensile strength = 30 N/mm2

- Temperature that can withstand = 65 to +150 C

(B) Intensive Care Unit Monitoring using UWB (Ultra Wideband)

-for remote monitoring and measuring the patients' motion in short dista

-When the patient moves, the reflected signals will fluctuate. The flsignals denoting the movement of objects is transferred to the control surveillant. The information could be fed back instantaneously to th

nurses.

-The application used to monitor the patients whether moving in thetime. UWB radar could measure the speed and position of the patient in

(C) Body Area Network (BAN) gateway to Android mobile phonmobile health applications

- This is based on a Secure Digital Input Output (SDIO) interface, whilong-term monitoring

- This mobile health monitoring system uses the Human++ BAN senretrieve bio-signals from the body and an Android mobile phone to cprocess, and send the data.

- Allows the user to visualize and send a daily summary of the hreporting the minimum, maximum and average heart rate.


14/21

(D) BAN Implantation (In future)

- In the near future, people affected by health issues such as Alzheimhearing loss, heart failure or even missing limbs could all have a smain-body or on-body device that makes their daily life easier.

- The development of tiny and ultra-low-power wireless communicatio

- However, only limited autonomy and wireless connectivity can be achtoday's wireless solutions because of their size and power consumptio

Analysis and Review Low emission power is the principle requirement on BAN as it is main

person.

It also means that interference level of BAN will be in a reasonable that it is tolerable by other wireless systems.

Other requirements on BAN

low power consumption, high security, reliability, etc

Zigbee (IEEE 802.15.4)a low-cost, low-power, wireless mesh network standard

Zigbee can operate at three different frequency bands o(worldwide), 800 MHz band (regional), and 900 MHz band (regiona

When operating at 2.4 GHz band, it achieves a maximum data kbps.

The drawback of IEEE 802.15.4 is also the limited data rate.

Bluetooth (IEEE 802.15.1)

also operates at 2.4 GHz band and can provide data rates of mMbps.

One disadvantage of Bluetooth is that it has higher emission power consumption.


17/21

Low rate UWB (IEEE 802.15.4a)It has the smallest emission power density and power consumptioThe UWB band operates between 3.110.6 GHz.

The nominal data rate of it is 850 kbps, which can be increased t26 Mbps in option.

A drawback of UWB band is that the transmission loss is so s

human body that it is difficult to be used for implantable BAN.


18/21

A comparison of normalized energy consumption is shown

From the mJ/Mb unit point of view, UWB has better efenergy consumption and it is a better solution to use forrate implementation.


19/21

Conclusion

Very useful technology in supporting medical and healthcar

Divided into wearable BAN and implant BAN

Potential to provide a better and less expensive alterrehabilitation healthcare

Provide benefit to patients and society through c

monitoring Number of challenging issues should be resolved

system design, configuration and customization, standardizatutilization of common off-the-shelf components, security and social issues
