Abstract: In this paper we investigated that Bluetooth wireless transmission standard accommodate a low-power data link between electronic devices over relatively abruptly ranges. These connections also known as Pico-nets transmit using frequency hopping spread spectrum (FHSS) to send data over the air. In many of Bluetooth technology becomes used the number of Bluetooth devices will continue to extending daily life. With this increase in use there will be a decrease in performance that can be blame to Bluetooth “inter-Pico-net” interference. Very small has been published on the subject of interpico-net interference. Previous to studies have derived mean packet error rates for an increase in the number of Pico-nets present. To analysis that the mean rate many papers make up the assumption that the probability of a Bluetooth device hopping to a channel is random. However making this examine does not explain what happens in actual time. This research gives some awareness into what really happens when multiple Pico-nets are interfering in day to day time. Bluetooth devices actually use a frequency hopping explanation to analysis hopping sequence. This explanation has been implemented in software to test various acts of looking aspects of interpico-net interference. Previous explanation has shown that synchronizing the clocks among neighboring Pico-nets will result in an increase in performance. This analysis shows there are cases where synchronization individual will not provide adequate improvement. Experimental testing has been conducted to validate some of the simulated results. Adjacent channel interference was analysis during experimentation. This dispute former research, which has accepted that adjacent channel disturbance, is inconsequential.
