Lab05_ATM
Asynchronous Transfer Mode (ATM) is a connection-oriented, packet-switched
technology. The packets that are switched in an ATM network are of a fixed length, 53
bytes, and are called cells. The cell size has a particular effect on carrying voice traffic
effectively. The ATM Adaptation Layer (AAL) sits between ATM and the variable-length
packet protocols that might use ATM, such as IP.

5-Mbps-optical-wireless-communication-with-error-
One issue with underwater sensors is how to efficiently transfer large amounts of data collected by the node to an interrogating platform such as an underwater vehicle. It is often impractical to make a physical connection between the node and the vehicle which suggests an acoustic or optical wireless solution. For large amounts of data, the high bandwidth of underwater optical wireless is an advantage. A small, low-cost platform to demonstrate the potential of an optical wireless communications
interface for underwater sensor nodes is demonstrated. To enhance the reliability and robustness of the optical wireless communication digital signal processing and error correction
techniques are used. The system was tested in 3 and 7.7 meter tanks at 5 Mbps with the turbidity of the water controlled by the addition of Maalox.
