

New concepts and technologies are rapidly emerging in the
fields of DySPAN and many of the terms do not have
precise definitions or have multiple definitions.
spectrum management,
policy defined radio,
adaptive radio,
software defined radio,
reconfigurable radio and networks and related
technologies.
The IEEE 1900.1 Working Group will develop a
standard to clarify these terminologies and how
these technologies relate to each other.

amplifying text that explains these technologies from different
perspectives.
 The document will also describe how these technologies
interrelate and can be use in a wide variety of communication
service environments


to achieve new capabilities while at the same time providing
mechanisms supportive of new spectrum management paradigms
and spectrum access.
Current Status

PAR is approved in March 2005;

IEEE Draft Standard P1900.1 is in the balloting and recirculation
stages.

IEEE 1900.4 Coexistence support for reconfigurable,
heterogeneous air interfaces

Purpose

To improve overall composite capacity and QoS of
wireless systems in a multiple Radio Access
Technologies (RATs) environment,


by defining an appropriate system architecture and
protocols which will facilitate the optimization of radio
resource usage,
in particular, by exploiting information exchanged
between network and mobile Terminals,

whether or not they support multiple simultaneous links and
dynamic spectrum access.
11
IEEE 1900.4

Scope
 The standard defines the building blocks for enabling coordinated
network-device distributed decision making which comprising:






network resource managers,
device resource managers,
the information to be exchanged between the building blocks,
will aid in the optimization of radio resource usage, including
spectrum access control, in heterogeneous wireless access
networks.
The standard is limited to the architectural and functional
definitions at a first stage.
The corresponding protocols definition related to the information
exchange will be addressed at a later stage.

Need for the Project


Multimode reconfigurable devices are increasingly being
adopted within the wireless industry.
The choice among various supported air interfaces on a
single wireless device is already a reality today,


with devices offering, for example, 2nd, 3rd generation cellular
radio access technologies and 802 wireless standards.
Last but not least, devices and networks with DSA
capabilities allowing the use of spectrum resource
simultaneously among different systems are emerging and
will be part of the radio eco-space.
