摘要： Free space optical communication is plagued by interruptions in the connections caused by atmospheric phenomena, such as weather. A wireless beam transmission system includes at least one transmitter (110) and accommodates several wavelengths, and at least one transmission wavelength is arranged to be chosen based on spectral absorption measurements of the atmosphere in the carrier beam path of communication. The invention concerns also a transceiver for repeating wireless optical communication signals. The long range and high reliability of spectroscopically sensitive light beams at a penetrating frequency allow the affordable provisioning of high bandwidth optical or IR communication connections to devices and buildings that were previously either very expensively connected to the fiber optic backbone networks, expensive low bandwidth radio or microwave networks, or unreachable by traditional free space optics solutions.

摘要： A balloon may include an optical-communication component, which may have a pointing axis. A pointing mechanism could be configured to adjust the pointing axis. The optical-communication component could be operable to communicate with a correspondent balloon via a free-space optical link. For example, the optical-communication component could include an optical receiver, transmitter, or transceiver. A controller could be configured to determine a predicted relative location of the correspondent balloon. The controller may control the pointing mechanism to adjust the pointing axis of the optical-communication component based on the predicted relative location so as to maintain the free-space optical link with the correspondent balloon.

摘要： A wireless communications link comprising an RF link and a free space optics (FSO) link, a switch, an RF signal monitoring apparatus, an optical signal monitoring apparatus, alarm apparatus and a controller. The switch operates in a normal mode to aggregate the links to form a link aggregation group and to route traffic on the link aggregation group, a first protection mode to route traffic on the FSO link, or a second protection mode to route traffic on the RF link. The controller is arranged to receive an alarm signal and to generate and transmit a control signal to cause the switch to operate in the first protection mode when a first alarm signal is received, the second protection mode when a second alarm signal is received, and the normal mode when an indicator is received indicating that both signal quality parameters are above their threshold values.
