A wireless camera system comprising: a battery powered wireless camera , including an internal battery to provide energy, a high-bandwidth radio using the IEEE 802.11 standard, a low-bandwidth radio , wherein the high-bandwidth radio is arranged to transmit information during burst periods; and a base station , separated from the battery powered wireless camera , in wireless communication with the battery powered wireless camera and configured to receive information from the battery powered wireless camera , characterized in that the base station is further configured to scan for available high-bandwidth radio transmission channels to determine whether there is an available high bandwidth radio transmission channel, and if a high bandwidth radio transmission channel is available, to reserve the available high bandwidth radio transmission channel by sending a clear-to-send/self signal and, once the high bandwidth radio transmission channel is reserved, to send information indicating that the reserved high bandwidth radio transmission channel is available to the battery powered wireless camera via a low-bandwidth channel associated with the low-bandwidth radio of the battery powered wireless camera, wherein the information indicating that the reserved high bandwidth radio transmission channel is available is transmitted as a clear-to-send/wake-up signal, and wherein the battery powered wireless camera is configured to, in response to the clear-to-send/wake-up signal, trigger a wake up-signal to the high-bandwidth radio to start transmitting image data from the camera to the base station via the reserved high-bandwidth radio channel. a battery powered wireless camera , including an internal battery to provide energy, a high-bandwidth radio using the IEEE 802.11 standard, a low-bandwidth radio , wherein the high-bandwidth radio is arranged to transmit information during burst periods; and a base station , separated from the battery powered wireless camera , in wireless communication with the battery powered wireless camera and configured to receive information from the battery powered wireless camera , characterized in that the base station is further configured to scan for available high-bandwidth radio transmission channels to determine whether there is an available high bandwidth radio transmission channel, and if a high bandwidth radio transmission channel is available, to reserve the available high bandwidth radio transmission channel by sending a clear-to-send/self signal and, once the high bandwidth radio transmission channel is reserved, to send information indicating that the reserved high bandwidth radio transmission channel is available to the battery powered wireless camera via a low-bandwidth channel associated with the low-bandwidth radio of the battery powered wireless camera, wherein the information indicating that the reserved high bandwidth radio transmission channel is available is transmitted as a clear-to-send/wake-up signal, and wherein the battery powered wireless camera is configured to, in response to the clear-to-send/wake-up signal, trigger a wake up-signal to the high-bandwidth radio to start transmitting image data from the camera to the base station via the reserved high-bandwidth radio channel. <EOS>
