Fujitsu Starts Verification Testing of Japan's First Medical Bod

Fujitsu Starts Verification Testing of Japan's First Medical Body Area Network 
Wireless measurement of vital signs to contribute to higher-quality medical care 
Tokyo, Apr 12, 2013 - (JCN Newswire) -  Fujitsu today announced that it has
successfully completed the first verification test in Japan for a medical body
area network (mBAN). Conforming to IEEE 802. 15.6 standards and using a
prototype device with a frequency band reserved for medical applications
(400MHz), the test was conducted at Fujitsu Clinic in Kawasaki, Japan. 
Conventionally, measuring such vital signs as the electrical activity of the
heart, brain waves, blood pressure, and body temperature for patients in a
hospital required hooking them up to wires, visually inspecting the results,
and then recording the results in a medical chart. By using mBAN, however, each
type of sensor can transmit signals wirelessly to measuring devices. As a
result, patient stress caused by being hooked up to obtrusive wires is reduced,
as is the assistance required from nurses. Furthermore, the risk of unexpected
connection problems with the wires is eliminated, and transcription errors in
medical charts are avoided, thus contributing to higher-quality medical care
and improved patient comfort. 
Fujitsu has positioned mBAN as a mainstream network for next-generation
healthcare and will continue its development efforts in this area. 
The verification test was part of a study project commissioned by Japan's
Ministry of Internal Affairs and Communications titled, "Studies on
advanced frequency application technologies for 400MHz-band medical
The Verification Test 
1. Objective 
In respect to the study commissioned by Japan's Ministry of Internal
Affairs and Communications titled, "Studies on advanced frequency
application technologies for 400MHz-band medical telemeters," the test
aimed to conduct research on the reliability and safety of wireless
transmission that medical facilities demand by evaluating the performance of
mBAN in actual hospital room conditions. 
2. Project period 
Research planning was carried out during fiscal 2011 and 2012, while the
verification testing occurred February 18-22, 2013. 
3. Location 
Hospital rooms at Fujitsu Clinic 
4. Verification Test overview 
In the verification test performed in hospital rooms at Fujitsu Clinic,
employees acted as patients. The prototype wireless device was attached to
various parts of their bodies, and, based on the actual conditions in hospital
rooms, the performance of the mBAN system was evaluated in relation to changes
in the position of equipment or the posture of the subjects. The test confirmed
that the data transmitted from the body sensors was reliable, and that having
multiple, independent mBAN in use in the same hospital room does not result in
interference, thereby verifying the safety of operating multiple mBANs
Overview of mBAN 
mBAN is a transmission standard specific to medical care applications.
Standardization was completed in February 2012 by the IEEE. The system achieves
low energy consumption by decreasing wireless output, thereby limiting the
transmission area to between three and five meters, and through the inclusion
of a sleep mode within the transmission protocol. As a result, devices
incorporating mBAN transmission modules can achieve long battery life. In
addition to the frequency band reserved for medical applications (400MHz), the
system is also compatible with the versatile ISM band (2.4GHz) and other
medical care-specific frequency bands employed by various countries.
