1.	Which among the following is not a requirement of services that are explicitly invoked?(a) Replicate user interface(b) Modeling user intent(c) Common means to describe user state(d) Automatic detection of input modalityThe question was asked during an interview.This interesting question is from Next Generation Wireless Network in portion Next Generation Wireless Network of Cognitive Radio
Answer» Right answer is (d) Automatic detection of input modality The EXPLANATION: Services can be provided by automatic detection or by explicit request. Cognitive RADIO employs hybrid request handling techniques with RESPECT to the applications. The service requires interfaces to represent the user state, predict the OUTCOME of a task, and to duplicate the human INTERFACE.
