Executive summary
The present document defines technical specifications for hub to hub communication capability for ETSI SmartBAN.
The specifications extend the general Medium Access Control (MAC) framework defined for SmartBAN by enabling
the communication between hubs of two neighbouring SmartBANs.
Hub to hub communication procedure can be divided into eight steps as follows:
1) Hub to hub communication initialization.
2) Neighbour SmartBAN discovery.
3) Inter-beacon interval realignment.
4) Resource pre-allocation.
5) Hub to hub connection initialization.
ETSI
5 ETSI TS 103 806 V1.1.1 (2023-11)
6) Hub to hub channel access.
7) Modifying hub to hub connection.
8) Ending hub to hub communication.
The present document is structured as follows: firstly, the additional management frames and information units required
for the hub to hub communication are defined. Secondly, the present document details the operational procedures for
the hub to hub communications. Finally, Annex A includes two normative flowcharts defining the hub to
communications.
Introduction
Modern medical and health monitoring equipment is moving towards the trend of wireless connectivity between the
data collection or control centre and the medical devices or sensors. Therefore, a standardized communication interface
and protocol between the actors are required. This network of actors performing some medical monitoring or functions
is called a Smart Body Area Network (SmartBAN).
A SmartBAN is a simple, low complexity, low energy communication network that allows wireless connectivity
between the devices and a hub. The distinct features of the SmartBAN are ease of access, minimal listening, reliable
data transfer, and provision of additional control messages (in the form of C-Beacons) for the low-duty cycling nodes
while maintaining a simple and flexible protocol. SmartBAN also provides a multi-use channel access mechanism for
emergency and other high-priority access and improved channel utilization.
The basic access specifications for Medium Access Control (MAC) are defined in [1] and for physical layer (PHY) in
[2]. The present document extends [1] by defining technical specifications for hub to hub communications enabling
communication between the hubs of neighbouring SmartBANs.
Additional information can be found in the following documents:
• ETSI EN 300 328-1 [i.1] defines requirements for equipment operating in the 2,4 GHz ISM band;
• IEEE 802.15.6-2012 [i.2] defines an alternative standard for Wireless Body Area Networks; and
• IEEE 802.15.4-2011 [i.3] defines a standard for Wireless Personal Area Networks;
• ETSI TS 103 805 [i.4] defines relay functionality for SmartBAN MAC defined in ETSI TS 103 325 [1].

1 Scope
The present document extends the low complexity Medium Access Control (MAC) for SmartBAN defined in ETSI
TS 103 325 [1] with hub to hub communication capability. The main scope of the present document is to define
specifications for enabling hub to hub communication between the hubs of neighbouring SmartBANs.
