The physical layer of a wireless communication system is generally considered to apply only to individual links within a wireless network. Physical Layer Network Coding (PLNC), aka Wireless Network Coding, in effect extends the physical layer across a wireless network: we may also call it “the network-aware physical layer”. Like Network Coding, it allows coding techniques to be appllied at network nodes, rather than simple switching, but in contrast it does not require data to be transmitted over separate channels, but exploits the broadcast character of wireless networks to combine data streams travelling by different routes through the network. The talk will introduce the basic ideas of PLNC using some simple examples, and then consider its application to next generation, ultra high capacity density, wireless broadband networks.
