INTEGRATED INFRASTRUCTURE FOR COEXISTENCE OF WIRELESS LAN AND WIRELESS SENSOR NETWORKS

摘要

A wireless communications method and system are presented, which include an industrial sensor network that comprises a plurality of industrial sensors, which communicate through one or more infrastructure nodes. A wireless communications network is established, which includes a plurality of wireless communications stations that communicates with one or more of the infrastructure nodes. The infrastructure node(s) can be modified to additionally function as a wireless access point for the wireless communications network utilizing a Time Division Multiplexing Algorithm (TDMA) data structure that supports two types of data transfers, such as Frequency Hopping Spread Spectrum (FHSS) for communications of the industrial sensor network and IEEE 802.11 for communications of the wireless communications network, thereby permitting the industrial sensor network to coexist and accommodate the wireless communications network.
