Abstract
Two or more personal area networks (or PANs) operating channel hopping schedules may be operated within a vicinity of one another with channel hopping schedules according to IEEE 802.15.4 that are separated by a frequency offset, and collisions between data transmitted by the respective devices of the networks may be avoided. Nodes of a first PAN transmit beacons identifying information regarding a first communications schedule. A node of a second PAN receives the beacon and establishes a second channel hopping schedule at the offset from the first communications schedule. Nodes of PANs may be programmed with communication modes that vary uplink or downlink slots based on quality-of-service or traffic requirements.
