Any book that addresses the topic of wireless communication could use the metaphor of the “one way street” to describe the radio communication. The flow occurs in only one direction, either transmits or receives, so this is the basic form of communication that we know, used in products such as Nextel, or even walkie-talkie. We talk and listen “at the same time” when using the mobile phone through a workaround that requires an expensive infrastructure that would not be appropriate for a wireless network, for example, in our homes. Recently, researchers from the Computer Science and Electrical Engineering at Stanford University developed the first wireless radio where you can send and receive signals at the same time, the project Full-Double Wireless Design.
The most obvious and direct impact of this result is the doubling of transmission capacity since transmission and reception can occurr at the same time. The scope of the impacts of this new approach is unpredictable because there since the mobile need to, for example, air traffic control. One thing is certain, the future is promising, since software and hardware are designed to take advantage of simultaneous communication.
