A wireless network includes a client device and an access point (AP). The client device generates a data packet having a physical layer protocol data unit frame format. The client device transmits the data packet to the AP such that a plurality of long training fields (LTFs) of the data packet is transmitted at higher power as compared to a data field of the data packet, and a preamble portion of the data packet is transmitted at higher power as compared to the plurality of LTFs. Further, the data field includes various resource units (RUs) and one such RU is utilized for data transmission between the client device and the AP. The transmission of the data packet from the client device to the AP in the aforementioned manner results in the range extension of the wireless network.
