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.

Claims

1. A method for assigning communication frequencies, the method comprising:

determining from a set of frequencies to be used, initial frequencies to be utilized by a plurality of Bluetooth communication devices residing on a single host device;

assigning a first portion of said determined initial frequencies to a first of said plurality of Bluetooth communication devices;

assigning at least a second portion of said determined initial frequencies selected from a remaining portion of said determined initial frequencies to at least a second of said plurality of Bluetooth devices residing on said single host device; and

allocating Bluetooth applications to said plurality of Bluetooth communication devices based on one or both of;

available bandwidth of each of said plurality of Bluetooth communication devices and/or an identifier of each of said Bluetooth applications.

2. The method according to claim 1, comprising reallocating said Bluetooth applications to said plurality of Bluetooth communication devices based on one or both of:

available bandwidth of each of said plurality of Bluetooth communication devices and/or said identifier of each of said Bluetooth applications.

3. A machine-readable storage having stored thereon, a computer program having at least one code section for assigning communication frequencies, the at least one code section being executable by a machine for causing the machine to perform steps comprising:

determining initial frequencies to be utilized by a plurality of Bluetooth communication devices residing on a single host device;

assigning a first portion of said determined initial frequencies to a first of said plurality of Bluetooth communication devices;

assigning at least a second portion of said determined initial frequencies selected from a remaining portion of said determined initial frequencies to at least a second of said plurality of Bluetooth devices residing on said single host device; and

allocating Bluetooth applications to said plurality of Bluetooth communication devices based on one or both of;

available bandwidth of each of said plurality of Bluetooth communication devices and/or an identifier of each of said Bluetooth applications.

4. The machine-readable storage accordingly to claim 3, comprising code for reallocating said Bluetooth applications to said plurality of Bluetooth communication devices based on one or both of:

available bandwidth of each of said plurality of Bluetooth communication devices and/or said identifier of each of said Bluetooth applications.

5. A system for assigning communication frequencies, the system comprising:

an application controller that determines initial frequencies to be utilized by a plurality of Bluetooth communication devices residing on a single host device;

said application controller assigns a first portion of said determined initial frequencies to a first of said plurality of Bluetooth communication devices;

said application controller assigns at least a second portion of said determined initial frequencies selected from a remaining portion of said determined initial frequencies to at least a second of said plurality of Bluetooth devices residing on said single host device; and

said application controller allocates Bluetooth applications to said plurality of Bluetooth communication devices based on one or both of;

available bandwidth of each of said plurality of Bluetooth communication devices and/or an identifier of each of said Bluetooth applications.

6. The system according to claim 5, wherein said application controller reallocates said Bluetooth applications to said plurality of Bluetooth communication devices based on one or both of:

available bandwidth of each of said plurality of Bluetooth communication devices and/or said identifier of each of said Bluetooth applications.
