  text: Cognitive radios (CR) can sense and detect temporarily available spectral
    holes for an opportunistic operation to improve the spectral efficiency and coexistence
    of industrial radio systems. It will be of particular interest for a CR system
    to apply predictive modeling in order to forecast the behavior of the coexisting
    environment. A secondary cognitive user shall use preemptive tuning of its operating
    parameters following the predictive model. However, a considerable challenge is
    to generate an accurate model and predict efficiently in order to meet strict
    time related requirements of industrial applications. Such predictive modeling
    has already gained some attention but real-time experimental results have never
    been reported to the best of our knowledge. In this contribution we investigate
    the performance of a Markov model based CR system using simulative and experimental
    environments for its application in industrial systems.

  text: The need for multiple radio systems in overlapping regions of a factory plant
    introduces a coexistence problem. The current research challenge is to design
    and realize radio systems that should be able to achieve a desired quality of
    service (QoS) in this coexisting environment. Currently transmission resources
    of hyperspace are not properly exploited. The cognitive radio (CR), which can
    adapt to the environmental changes by reconfiguring itself, can be used to implement
    intelligent radio systems to exploit the orthogonal nature of multiple dimensions
    of hyperspace to maintain the desired QoS in coexisting factory environments.
    We present initial results of a coexistence optimized CR which can exploit frequency
    and power, which are two of several dimensions of hyperspace, to improve its QoS
    in coexisting environments.
