+ * Each radio has a set of parameters that designate the current
+ * configuration and state of the radio. Parameters can either have
+ * values of type radio_value_t, or, when this type is insufficient, a
+ * generic object that is specified by a memory pointer and the size
+ * of the object.
+ *
+ * The radio_value_t type is set to an integer type that can hold most
+ * values used to configure the radio, and is therefore the most
+ * common type used for a parameter. Certain parameters require
+ * objects of a considerably larger size than radio_value_t, however,
+ * and in these cases the documentation below for the parameter will
+ * indicate this.
+ *
+ * All radio parameters that can vary during runtime are prefixed by
+ * "RADIO_PARAM", whereas those "parameters" that are guaranteed to
+ * remain immutable are prefixed by "RADIO_CONST". Each mutable
+ * parameter has a set of valid parameter values. When attempting to
+ * set a parameter to an invalid value, the radio will return
+ * RADIO_RESULT_INVALID_VALUE.
+ *
+ * Some radios support only a subset of the defined radio parameters.
+ * When trying to set or get such an unsupported parameter, the radio
+ * will return RADIO_RESULT_NOT_SUPPORTED.
