FIELD: communication.
SUBSTANCE: invention relates to wireless communication. Device includes processor, configured to generate packet for transmission using wireless signal. Packet is generated for transmission over bandwidth of 1 Mhz, using, at least, one orthogonal frequency division multiplexing (OFDM) symbol, containing 32 subcarriers, described by indices from -16 to 15, in which each of these 32 subcarriers has average package energy. Device further includes transmitter, configured, to implement packet transmission using wireless signal so, that each average package energy for subcarriers, having indices from -8 to -1 and from 1 to 8, deviates for not more than ± 4 dB of average package energy full average value by subcarriers, having indices from -8 to -1 and from 1 to 8, and each average package energy for subcarriers, having indices from -13 to -9 and 9-13, deviates for not more than +4/ -6 dB of full average value.
EFFECT: technical result consists in provision of wireless communication in sub-gigahertz frequency bands for wireless communication at low power and on long distances.
