Abstract

The present invention relates to a method (300) and a system (100) including a client (125) and a network controller (120) to communicate with the client using frequency hopping. The network controller (120) is operative to determine a frequency quality measurement value for each of a plurality of frequencies, the network coordinator (120) can use in a frequency hopping sequence for communicating with a client; classify each of the plurality of communication frequencies into one of a plurality of different categories based on a relative ranking of the determined frequency quality measurement value of each of the plurality of frequencies; generate a frequency hopping sequence to be used for communication between the network coordinator (125) and the client (120), the generated hopping sequence including only select frequencies from the plurality of frequencies in a predetermined number of future time slots that minimize a probability of a predetermined number of consecutive frequency hop failures in the predetermined number of future time slots; and notify the client of the generated frequency hopping sequence to be used for communication between the network coordinator (120) and the client (125).

Description

[0001] Cross reference of related applications [0002] This application claims the priority of 61 / 091,275 of the US Provisional Application titled "A Reliable Wireless Communication System Using Adaptive Frequency Hopping" filed on August 22, 2008, the entire contents of which are incorporated herein by reference. Technical field [0003] In general, the embodiments described herein relate to communication systems. More specifically, some embodiments relate to a wireless communication system using an adaptive frequency hopping sequence, wherein the network coordinator monitors the communication between communication devices in the network and adapts the frequency hopping sequence of the network to minimize the chance of communication interruption. Background technique [0004] Various environments including industrial automation applications may require highly reliable networks for communication. In some applications, if several consecutive data packets from the controller to the ...
