Compensating for interruptions in a wireless connection

A method of compensating for potential interruptions (e.g., for maintenance: beamforming, channel changing, reduced-power or sleep modes) in a wireless spatially selective connection, over which data at a first (e.g., zero, no) compression level is transmitted from a host to a client device, comprises: determining (S32) that an interruption to the wireless spatially selective connection is starting or is due to start; compressing (S3Y3) the data at a second compression level higher than the first compression level; and forwarding (S34) the data compressed at the second compression level to a transmitting component for wireless spatially non-selective broadcast while the interruption occurs. Determining that the interruption is due to start may involve analysing a historical record of previous interruptions to determine a periodicity of previous interruptions, or by receiving information from the transmitting component. Duration of the potential interruption may be calculated based on determined periodicity. Determining that the interruption is starting may involve determining that a buffer used for storing the data prior to transmittal is full, indicating an interruption has commenced. An interruption end may be assessed by determining the buffer is able to accept data at a rate higher than a predetermined threshold rate.
