Frequency hopping technique for multiple frequency bands in networks

Abstract

An approach talking about orthogonal frequency hopping patterns definition and a unique way of defining hopping patterns for a time division multiple access (TDMA) wireless sensor networks doing frequency hopping. A frequency hopping pattern may cover virtually any frequency usage for each sensor and handle interference in wireless medium reliably. One may define various orthogonal hopping patterns which are non-interfered between multiple sensor networks present in the same vicinity. One may use TDMA networks for frequency hopping. To make the communication of multiple FTDMA wireless networks work concurrently without much packet collision with greater than 99 percent reliability, one may devise a unique way of generating a frequency hopping pattern (FHP) scheme in various licensed and license free frequency bands. An FHP may be a sequence of n frequencies which is followed by the whole wireless mesh, and the sequence keeps repeating after the nth time slot.
