It was made research of factors that have the influence to effective data rate of digital channel of wireless sensor network standard 802.15.4. Due to implementation research Makarov model of wireless sensor network data link layer was updated. Proposed model is corrected for data frame retransmission to effective data rate network considering retransmitting and backoff time. It was identify that under the influence of electromagnetic influence to the channel the choice of data frame size allows to improve effective data rate more than in twice.
