Abstract: A device is provided, which includes radio-frequency circuitry and an encoder. The encoder is configured to modulate input data to generate a long-range packet, and to transmit the long-range packet to a receiver through the radio-frequency circuitry. The long-range packet includes a long-range signal field (LR-SIG) and a long-range data field (LR-DATA). Each modulated bit in the long-range signal field and the long-range data field is spread into a plurality of spread modulated bits that are distributed into a plurality of symbols in a frequency domain.

Abstract: A channel allocation method for a communication device to perform in a wireless personal area network (WPAN) following IEEE 802.15 or SIG protocol, and the communication device is able to operate across a plurality of frequency bands. The channel allocation method includes the following steps. A working frequency band within the plurality of frequency bands is determined, the working frequency band includes at least one clean channel and other channels. One of the at least one clean channel is selected to operate in the WPAN, by the communication device. The at least one clean channel is not used by another communication device in a wireless local area network (WLAN) following IEEE 802.11 protocol.
