Abstract: A system may include a first full duplex split site system and a second full duplex split site system. The first full duplex split site system may include a first transmitter and a first receiver. The second full duplex split site system may include a second transmitter and a second receiver. The first transmitter may be configured to transmit a data payload to the second receiver via a high frequency (HF) link on a first frequency. The first receiver may be configured to: instruct the first transmitter to send a command to the second receiver to instruct the second transmitter to establish a maintenance link with the first receiver on a frequency different from the first frequency; and command the first transmitter to begin transmitting the data payload to the second receiver.

Abstract: In a wireless network having a plurality of nodes configured to send and receive messages between each other, a method is disclosed for determining whether a message sent from a sending node to a receiving node has been successfully transmitted. The sending node transmits an identifying command to the receiving node that describes the sent message. The receiving node compares the description of the sent message with a received message that the receiving node has received. The receiving node responds to the sending node, said response indicating to the sending node the results of the comparison between the description of the sent message and the received message. The sending node transmits a portion of the sent message if the comparison between the received message and the description of the sent message indicates that the receiving node has not yet received the portion of the sent message.

Abstract: A communication system can utilize a STANAG 5066 profile and include a data rate link mechanism. The data rate link mechanism can reside in a linking layer, such as, a subnetwork management sublayer according to the STANAG 5066 application. The mechanism allows data rate change functions of HF messages to increase throughput upon link establishment. Link quality can be determined by LQA signals generated according to MIL-STD-188-141B profiles.

Abstract: A method of transmitting data over a single-channel wireless network having a plurality of nodes is disclosed. According to the method, a first link is established between two of the nodes and data is transmitted therebetween. A break in transmission between the two nodes is listened for, and a first predetermined time interval is waited if a break in transmission between two nodes occurs. A second predetermined time interval is established if the first predetermined time interval lapses with no detected transmission over the channel. The second predetermined time interval is divided into a plurality of slots, and each node randomly selects one of the slots. One of the nodes establishes a second link if that node has selected a slot earlier in time than slots selected by the remainder of the nodes.
