A method in a wireless communication network infrastructure entity, including transmitting a plurality of symbols in a sequence, some of the symbols associated with a first transmission mode, for example, point-to-point, and some other symbols associated with a second transmission mode, for example, point-to-multipoint, different than the first transmission mode. The processes and systems are found to be particularly useful for the blending of two or more hydrocarbon streams to economically produce a targeted hydrocarbon product stream meeting prescribed compositional specifications. The transmitter is used for emitting a radio signal to penetrate a superficial layer of the living body. The second display unit is electrically connected to the body when the first cover member is coupled to the body.
