Instead, the MAC layer protocol opportunistically recruits relay stations on the fly. Network capacity and delay performance is much better than legacy IEEE 802.11g network, and even cooperative forwarding using one relay station. Avoiding the need to collect the station-to-station channel statistics considerably reduces overhead otherwise required for channel measurement and signaling. | 2011-05-12 |
20110110291 | RELAY DEVICE AND WIRELESS CONTROL NETWORK MANAGEMENT SYSTEM USING THE SAME - There is provided a relay device for relaying first wireless communication and second wireless communication. The first wireless communication is based on a process control wireless communication standard, and the second wireless communication is based on another wireless communication standard than the process control wireless communication standard. The device includes: a superframe management unit configured to receive a first superframe of the first wireless communication from the outside and generate a second superframe of the second wireless communication based on the first superframe; and a transmission unit configured to transmit the second superframe to a wireless communication terminal performing the second wireless communication. | 2011-05-12 |
