MULTI-RADIO FREQUENCY INTERFERENCE IN UNLICENSED BANDS

The increasing density and data rate of unlicensed band wireless devices has led to significant inter- and intra-radio interference problems Multiple competing standards such as the IEEE 802.11b/g, Bluetooth and ZigBee, all of which operate in the 2.4 GHz ISM band, can interfere with each other when used in typical indoor environments, potentially causing significant performance degradation. This thesis aims to characterize different types of heterogeneous interference in the 2.4 GHz unlicensed band and develop techniques to diagnose interference related problems. We have discussed in this report the different type of topology and spectrum band used in unlaced radio frequency. We have described the planning method of 2.4 GB wifi network to avoidance of the interference and collision of the traffic. We have used the latest toll of insider to scan the different radio frequency coming from the other device and strength of the signal of the device. We have created the various set up channel interference and measured the through put by the Netper sec software. Validation experiments show that broad auto-classification of multi-radio interference in terms of congestion, slow links, inter AP interference and Bluetooth interference.
