Reconfigurability
Encyclopedia
Reconfigurability denotes the Reconfigurable Computing
capability of a system, so that its behavior can be changed by reconfiguration, i. e. by loading different configware code. This static reconfigurability distinguishes between reconfiguration time and run time. Dynamic reconfigurability denotes the capability of a dynamically reconfigurable system that can dynamically change its behavior during run time, usually in response to dynamic changes in its environment.
In the context of wireless
communication
dynamic reconfigurability tackles the changeable behavior of wireless networks and associated equipment, specifically in the fields of radio spectrum
, radio access technologies, protocol
stacks, and application services.
In the context of Control reconfiguration
, a field of fault-tolerant control within control engineering
, reconfigurability is a property of faulty systems meaning that the original control goals specified for the fault-free system can be reached after suitable control reconfiguration.
Research regarding the (dynamic) reconfigurability of wireless
communication
systems is ongoing for example in working group 6 of the Wireless World Research Forum
(WWRF), in the Wireless Innovation Forum
(WINNF) (formerly Software Defined Radio Forum), and in the Europe
an FP6 project End-to-End Reconfigurability (E²R). Recently, E²R initiated a related standardization effort on the cohabitation of heterogeneous wireless radio systems in the framework of the IEEE P1900.4 Working Group.
Reconfigurable computing
Reconfigurable computing is a computer architecture combining some of the flexibility of software with the high performance of hardware by processing with very flexible high speed computing fabrics like field-programmable gate arrays...

In the context of wireless
Wireless
Wireless telecommunications is the transfer of information between two or more points that are not physically connected. Distances can be short, such as a few meters for television remote control, or as far as thousands or even millions of kilometers for deep-space radio communications...

Communication
Communication is the activity of conveying meaningful information. Communication requires a sender, a message, and an intended recipient, although the receiver need not be present or aware of the sender's intent to communicate at the time of communication; thus communication can occur across vast...

In the context of Control reconfiguration
Control reconfiguration
Control reconfiguration is an active approach in control theory to achieve fault-tolerant control for dynamic systems . It is used when severe faults, such as actuator or sensor outages, cause a break-up of the control loop, which must be restructured to prevent failure at the system level...
