A burst of data in a wireless network includes a preamble [ 502 ], a postamble [ 504 ] and one or more blocks of data [ 506 ]. A low or no power receiving device [ 102 ] receives the preamble [ 502 ]. When the preamble [ 502 ] includes an ID of the receiving device, structural information of the burst is derived from the preamble [ 502 ], indicating when at least one component of the device is to be powered on to receive the at least one block of data [ 506 ] included in the burst. The at least one component [ 306, 308, 310 ] is powered on at a first time period in order to receive the data in the one or more blocks of data. The at least one component [ 306, 308, 310 ] is powered off at a specific time period from a beginning of the first time period. The powering on and off are repeated for each of the one or more blocks of data [ 506 ] in the burst.
