Abstract

A method for frequency separation for multiple Bluetooth communication devices on a single platform may comprise determining initial frequencies to be utilized by a plurality of Bluetooth communication devices residing on a single host device. A first portion of the determined initial frequencies may be assigned to a first of the plurality of Bluetooth communication devices. At least a second portion of the determined initial frequencies selected from a remaining portion of the determined initial frequencies may be assigned to at least a second of the plurality of Bluetooth devices. Determination may be made based on those determined initial frequencies that have been interfered with by other wireless communication devices. At least a portion of these frequencies that have been interfered with may be eliminated from the determined initial frequencies. The eliminating may be done dynamically and the determined initial frequencies may be re-assigned based on the eliminating.
