AV2 E(Audio Visual Vital & Environment) Communication System
 BAN nodes should be ultra-low power wireless sensors & actuators.
 Smart body hub becomes coordinator & communicator between BAN nodes and access tools,
such as smart phone, DTV or other internet nodes.

BT SIG
1. IEEE11073 is used as an API
2. Weak at network constructions.
Up to 7 terminals are connected in a Network
3. Even class 3 needs to reduce power consumption.
IEEE802.15.6
IEEE 802.15
1. Published in Feb. 2012.
2. MAC is suitable for Medical/Healthcare applications.
3 MAC is complicated and more simplification is required.
4. The simplification should lead the reduction of power
consumptions.
Ultra simple MAC for ultra
low power consumption will
be very important.
IEEE802.15.4j
IEEE 802.15
Medical BAN specifications for US dedicated medical band (2.362.40GHz)
IEEE802.15.4n
IEEE 802.15
1. Medical BAN specification for Chinese dedicated medical band
(174-216 MHz, 407-425 MHz and 608-630 MHz)
2. Call for application was issued in the July meeting
ETSI eHealth
ETSI /EU
1. ETSI BAN project is considered.
15
Current Status of IEEE 802.15
 IEEE 802.15.6
 As an option, we hope Ultra simple MAC for Ultra low power
consumption should be considered in IEEE 802.15.
 IEEE802.15.6a may be a reasonable place to be discussed.
 Prof. Kohno made a presentation for a new work item in the July
meeting.
(15-12-0370-00-wng0-dependable-wireless-m2m-network-forcontrolling-applications-for-cars-energy-medicine-cities)
 Extend IEEE802.15.6 or make another specification?
 Best Practice or Amendment of IEEE802.15.6?
 What to be included in the document?
– Routing and error-controlling protocols which have not done in
IEEE802.15.6 and others
– Joint optimization among technologies multiple layers of PHY, MAC and
upper layers including network architecture, authentication and
encryption for dependability
 A New IG was decided to be established.
16
Summary
 24 hours monitoring of human AV2E information and its
record contribute future medication as well as current and
emergency medication.
 BAN suitable for Medical/healthcare requires ultra simple
MAC in order to be ultra low power consumption.
 Extend IEEE802.15.6 or make another specification?
 ETSI e-Health will discuss in ETSI BAN project?
