and sending a control packet in response to the downlink data packet over the first wireless link using a reduced power setting during the communications over the second wireless link, the reduced power setting being less than a non-control packet power setting. ## Claims ### Claim 1 A method comprising: receiving a downlink data packet over a first wireless link using a first wireless protocol during communications over a second wireless link using a second wireless protocol, the first and second wireless protocols being different; and sending a control packet in response to the downlink data packet over the first wireless link using a reduced power setting during the communications over the second wireless link, the reduced power setting being less than a non-control packet power setting. ### Claim 2 (depends on 1) The method of claim 1, wherein the first wireless protocol is a wireless protocol according to an IEEE 802.11 family of standards. ### Claim 3 (depends on 1) The method of claim 1, wherein the second wireless protocol is a wireless protocol according to a BLUETOOTH family of standards. ### Claim 4 (depends on 1) The method of claim 1, wherein the first and the second wireless protocols utilize overlapping frequency spectrums. ### Claim 5 (depends on 1) The method of claim 1, comprising receiving a second downlink data packet over the first wireless link and responsive to determining that no communications are ongoing over the second wireless link, sending a second acknowledgement over the first wireless link using a normal power setting, the normal power setting greater than the reduced power setting. ### Claim 6 (depends on 5) The method of claim 5, wherein determining that no communications are ongoing over the second wireless link comprises determining whether a first or second communication core which respectively handles the first and second communication protocols is currently active based on a time division scheme. ### Claim 7 (depends on 1) The method of claim 1, wherein the reduced power setting is based upon a received signal strength indication. ### Claim 8 A communication apparatus comprising: a first communications module configured to communicate over a first wireless link using a first wireless protocol; a second communications module configured to communicate over a second wireless link using a second wireless protocol, the second protocol different than the first protocol; and wherein the first communications module is configured to send a control packet in response to a downlink data packet received over the first wireless link using a reduced power setting while the second communications module is communicating over the second wireless link, the reduced power setting being less than a non-control packet power setting. ### Claim 9 (depends on 8) The apparatus of claim 8, wherein the first wireless protocol is a wireless protocol according to an IEE 802.11 family of standards. ### Claim 10 (depends on 8) The apparatus of claim 8, wherein the second wireless protocol is a wireless protocol according to a BLUETOOTH family of standards. ### Claim 11 (depends on 8) The apparatus of claim 8, wherein the first and second wireless protocols utilize overlapping frequency spectrums. ### Claim 12 (depends on 8) The apparatus of claim 8, wherein the first communications module is configured to receive a second downlink data packet over the first wireless link and responsive to determining that no communications are ongoing over the second wireless link, the first communication module is configured to send a second acknowledgement over the first wireless link using a normal power setting, the normal power setting greater than the reduced power setting. ### Claim 13 (depends on 12) The apparatus of claim 12, wherein determining that no communications are ongoing over the second wireless link comprises determining whether the first or second communication modules is currently active based on a time division scheme. ### Claim 14 (depends on 8) The apparatus of claim 8, wherein the reduced power setting is based upon a received signal strength indication. ### Claim 15 A machine readable medium that stores instructions which when performed by a machine, cause the machine to perform operations comprising: receiving a downlink data packet over a first wireless link using a first wireless protocol during communications over a second wireless link using a second wireless protocol, the first and second wireless protocols being different; and sending a control packet in response to the downlink data packet over the first wireless link using a reduced power setting during the communications over the second wireless link, the reduced power setting being less than a non-control packet power setting. ### Claim 16 (depends on 15) The machine-readable medium of claim 15, wherein the first wireless protocol is a wireless protocol according to an IEE 802.11 family of standards. ### Claim 17 (depends on 15) The machine-readable medium of claim 15, wherein the second wireless protocol is a wireless protocol according to a BLUETOOTH family of standards. ### Claim 18 (depends on 15) The machine-readable medium of claim 15, wherein the first and second wireless protocols utilize overlapping frequency spectrums. ### Claim 19 (depends on 15) The machine-readable medium of claim 15, wherein the instructions comprise instructions which when performed by the machine, cause the machine to perform operations comprising: receiving a second downlink data packet over the first wireless link and responsive to determining that no communications are ongoing over the second wireless link, sending a second acknowledgement over the first wireless link using a normal power setting, the normal power setting greater than the reduced power setting. ### Claim 20 (depends on 19) The machine-readable medium of claim 19, wherein the instructions for determining that no communications are ongoing over the second wireless link includes instructions, which when performed by the machine, cause the machine to determine whether a first or second communication core which respectively handles the first and second communication protocols is currently active based on a time division scheme. ### Claim 21 (depends on 15) The machine-readable medium of claim 15, wherein the instructions for sending an acknowledgement using a reduced power setting includes instructions, which when performed by the machine, causes the machine to determine a power setting based upon a received signal strength indication.
