Evologics will appear at the Oceanology 2010 Conference to demonstrate the advantages S2C technology provides for underwater acoustic communication and positioning. Oceanology will be held 9-11 March 2010 in London. S2C signals are reliable for data transmission and positioning, in particular under noisy environments and shallow and confined waters. Evologics will share with participants of the congress its experience with sub-sea monitoring, sub-sea production systems, operation of robots, AUVs (and ROVs) and wireless acoustic networks. The reliability of S2C pushes the envelope in ocean business and offshore operations to areas that were not yet thought to be possible. Advanced algorithms guarantee maximum channel utilisation under all conditions, data delivery and simultaneous command transmission. Evologics will officially present Sonobot for the first time at Oceanology, an autonomous cartography and surveillance robot with an integrated high-precision S2C bionic sonar differenti...

Evologics S2C acoustic modems have been used in an underwater communication project for the Institute for Infocomm Research (I2R) in Singapore. I2R is building an Underwater Acoustic Sensor Network (UASN) and the S2C acoustic modems perform as network adapters for underwater nodes, providing both the physical layer and the data link layer required for networking applications. Robust instant message delivery and an efficient high-speed point-to-point communication, together with broadcasting capability, is said to allow for powerful network protocol development. I2R tried out different networking protocols, evaluating their feasibility for various application scenarios. I2R reported that the reliability features on S2C modems helped achieve excellent packet delivery ratios. Results from the experiment over four hop networks showed P2P mode with achievement of 100 per cent packet delivery.
