All high-rise buildings must have an on-site command station to receive and relay all alarms.
When Neil Armstrong stepped onto the moon, in 1969, the first images of his momentous leap were received and relayed by antennas at the Honeysuckle Creek Tracking Station, nestled in the foothills of a remote mountain valley in the Australian Alps, south of Canberra.
where i denotes the time instant corresponding to one symbol in the transmitted packet and its received and relayed copies.
The wireless network consists of a collection of nodes which can send, receive and relay data across wireless links.
By using a combination of probabilistic and gossip-like techniques and mechanisms, Rappel provides noiselessness, i.e., updates from any feed are received and relayed only by nodes that are subscribers of that feed.
In contrast with such conventional systems which have only one single destination node and a relatively small number of potential relay nodes, cooperative broadcast (CB [3] has been proposed for multiple destinations to receive one message in the network, where destinations can be switched between receiving and relay modes.
Each of the network members was assumed to have the potential of receiving, recording, and relaying information; however, it was also expected that one or more family physicians or pediatricians would play a central role in network communications.
While there are several accident notification systems, like OnStar and BMW Assist, BMW has added a feature that estimates the injuries passengers have received and relays that information to medical personnel.
When a referenced sensor node is in the full-active phase of the active mode, it may sense data packets, transmit the sensed packets, receive packets, and relay the received packets.
During the first TS, a symbol is first broadcast by the BS at a subcarrier and received by the RS and the MS. In relay-aided mode, the RS decodes the received symbol and relays it to the targeted MS over this subcarrier with the BS keeping quiet at the subcarrier during the second TS.
