Abstract: Methods and systems for controlling an asset tracking device and, in particular, determining when an asset tracking device is aboard a ship. The device may have a ship mode in which the device determines it has been loaded onto a ship and in which geolocation is not determined. The device may further have an ocean mode to which it transitions from the ship mode in which it ceases to look for a cellular connection in order to send location reports. The device may detect a beacon signal from a ship-mounted base-station to trigger the ship mode and may detect, or fail to detect, one or more wireless signals or identifiers as the trigger to transition to ocean mode.

Abstract: Disclosed herein are methods and systems for optimizing signal quality in an optical network having two or more hub nodes continuously outputting optical signals to a plurality of leaf nodes. Each of the plurality of leaf nodes may receive a combined optical signal from the hub nodes and determine an optical power and a signal quality of one optical subcarrier group and send a correction signal to the hub node that sent the subcarrier group. The hub nodes may send a power optimization request comprising the optical power and signal quality of each subcarrier group to a network controller. The network controller may use the optical power and signal quality to determine a power update for an optical power of the subcarrier group(s) and send the power update to the hub node transmitting the subcarrier group. The hub node may adjust the optical power based on the power update.

A new leaf node may begin transmitting a new subcarrier group at a gradually increasing transmission output power until it reaches the required receive signal quality margin. The new leaf node gradually increases the transmission output power of the new subcarrier group until the hub node determines that any of the plurality of subcarrier groups and the new subcarrier group reached a maximum transmission output power or the signal quality of one or more of the plurality of subcarrier groups and the new subcarrier group begins to degrade.
