Systems and methods for reducing interference in a TDMA based wireless network are provided. Such systems and methods can include a wireless access point forming a wireless network, the wireless access point selecting a first information channel, a second information channel, and a plurality of operating channel sequences from a plurality of wireless network channels used by the wireless network, the wireless access point assigning a first operating channel sequence of the plurality of operating channel sequences to the wireless access point and a second operating channel sequence of the plurality of operating channel sequences to a wireless repeater, the wireless access point hopping between each one of the first operating channel sequence in different ones of superframes used by the wireless network, and the wireless repeater hopping between each one of the second operating channel sequence in the different ones of the superframes.

A method and apparatus for maintaining network connectivity over power lines is disclosed. Such network connectivity is maintained even if various customers are covered by different power line networks or if one or more power lines in a network are unavailable to transmit data. More particularly, in order to bridge a gap in a power line network, one or more messages are extracted from a first node in a power line network and are then transmitted to a second node via free space transmission. When those messages are received at the second node, the message is injected back into the power line on the other side of a gap in power line coverage. This method of transmission backup will continue until power line connectivity is restore upon which the preferred method will be selected and used.

The invention relates to an AIS data transmission method using AIS standard-compliant AIS signals. The AIS data (5) to be transmitted is converted into AIS signals on the transmitter side and transmitted via a main channel (41). The AIS signals are received in an AIS receiver (2, 3) and converted back into received AIS data (6, 7). Error-correcting redundancy data is generated from the AIS data (5) to be transmitted or from parts of said data on the transmitter side, and the redundancy data can be used on the receiver side to correct errors of the received AIS data (6, 7). The redundancy data is converted into redundancy signals on the transmitter side and transmitted via an auxiliary channel (42) provided in addition to the main channel (41). The invention further relates to a corresponding AIS transmitter, a corresponding AIS receiver, and an AIS transceiver. The invention further relates to a system consisting of AIS transmitters and AIS receivers and to a computer program.
