The invention relates to a wireless network of devices including a network device and a coordinator; the coordinator comprising transmission and reception means for wireless communication; and the network device comprising transmission means and reception means for wireless communication; and control means operable to selectively cause the device to communicate according to two different channel access schemes, a higher throughput scheme and a lower throughput scheme; wherein a trigger is provided in the network for a switch from the lower throughput scheme to the higher throughput scheme, wherein the trigger is determined taking into account the network device's transmission requirements. The transmission requirements may be based on a network according to the present invention, wherein the transmission requirements are defined based on one or more of the following factors: data waiting in the network device's buffer, emergency status of a device, urgency status of a device and battery level. |
