Abstract

An apparatus and method are presented for a maximum speed criterion for a velocity gesture. The apparatus includes a processor, a memory, a determination module and a transmission module. The determination module determines, through a wireless communication infrastructure mode, an amount of wireless network activity. The transmission module sets a rate of data transmission in a peer to peer mode based on the amount of wireless network activity.

Claims

1. An apparatus comprising:

a processor;

a memory storing module for execution by the processor, the memory comprising;

a determination module determining, through a wireless communication infrastructure mode, an amount of wireless network activity; and

a transmission module setting a rate of data transmission in a peer to peer mode based on the amount of wireless network activity.

2. The apparatus of claim 1, wherein the data transmission comprises an ongoing data transmission and wherein the transmission module adjusts a rate of the ongoing data transmission in the peer to peer mode based on the amount of wireless network activity.

3. The apparatus of claim 1, wherein the transmission module decreases the rate of data transmission in the peer to peer mode in response to the determination module determining that the amount of wireless network activity is above a threshold and wherein the transmission module increases the rate of data transmission in the peer to peer mode in response to the determination module determining that the amount of wireless network activity is below a threshold.

4. The apparatus of claim 1, wherein the data transmission comprises video data and wherein the transmission module setting the rate of data transmission comprises the transmission module setting a video quality of the video data.

5. The apparatus of claim 4, wherein the transmission module setting the video quality of the video data comprises one or more of the transmission module setting a video frame rate, a video refresh rate, a video color depth, and a video resolution.

6. The apparatus of claim 1, further comprising a trigger module triggering the determination module to determine the amount of wireless network activity in response to one of a predetermined amount of data transmitted in the peer to peer mode and a predetermined amount of time.

7. The apparatus of claim 1, wherein the determination module determining the amount of wireless network activity further comprises the determination module searching for an available wireless channel, the transmission module decreasing the rate of data transmission in the peer to peer mode in response to the determination module failing to locate the available wireless channel, wherein the determination module determines an amount of wireless activity on the available channel in response to the determination module locating the available wireless channel.

8. The apparatus of claim 7, wherein the transmission module decreases the rate of data transmission in the peer to peer mode in response to the determination module determining that the amount of wireless network activity on the available channel is above a threshold and wherein the transmission module increases the rate of data transmission in the peer to peer mode in response to the determination module determining that the amount of wireless network activity on the available channel is below a threshold.

9. A method comprising:

determining, through a wireless communication infrastructure mode, an amount of wireless network activity; and

setting a rate of data transmission in a peer to peer mode based on the amount of wireless network activity.

10. The method of claim 9, further comprising decreasing the rate of data transmission in the peer to peer mode in response to determining that the amount of wireless network activity is above a threshold and increasing the rate of data transmission in the peer to peer mode in response to determining that the amount of wireless network activity is below a threshold.

11. The method of claim 9, wherein the data transmission comprises video data and wherein setting the rate of data transmission comprises setting a video quality of the video data and wherein setting the video quality of the video data comprises one or more of setting a video frame rate, a video refresh rate, a video color depth, and a video resolution.

12. The method of claim 9, wherein determining the amount of wireless network activity further comprising searching for an available wireless channel.

13. The method of claim 12, further comprising decreasing the rate of data transmission in the peer to peer mode in response to failing to locate the available wireless channel.

14. The method of claim 12, further comprising determining an amount of wireless activity on the available channel in response to locating the available wireless channel.

15. The method of claim 14, wherein determining the amount of wireless activity on the available channel further comprises:

broadcasting a Request To Send (“

RTS”

) frame on the available channel;

receiving a Clear To Send (“

CTS”

) frame from an access point on the available channel, the CTS frame describing a transmission time; and

determining the amount of wireless activity on the available channel based on the transmission time in the CTS frame.

16. The method of claim 15, further comprising decreasing the rate of data transmission in the peer to peer mode in response to determining that the amount of wireless network activity on the available channel is above a threshold and increasing the rate of data transmission in the peer to peer mode in response to determining that the amount of wireless network activity on the available channel is below a threshold.

17. A computer program product comprising a storage device storing machine readable code executed by a processor to perform the operations of:

determining, through a wireless communication infrastructure mode, an amount of wireless network activity; and

setting a rate of data transmission in a peer to peer mode based on the amount of wireless network activity.

18. The computer program product of claim 17, further comprising decreasing the rate of data transmission in the peer to peer mode in response to determining that the amount of wireless network activity is above a threshold and increasing the rate of data transmission in the peer to peer mode in response to determining that the amount of wireless network activity is below a threshold.

19. The computer program product of claim 17, wherein the data transmission comprises video data and wherein setting the rate of data transmission comprises setting a video quality of the video data wherein setting the video quality of the video data comprises one or more of setting a video frame rate, a video refresh rate, a video color depth, and a video resolution.

20. The computer program product of claim 17, wherein determining the amount of wireless network activity further comprising searching for an available wireless channel and further comprising decreasing the rate of data transmission in the peer to peer mode in response to failing to locate the available wireless channel and determining an amount of wireless activity on the available channel in response to locating the available wireless channel, further comprising setting the rate of data transmission in the peer to peer mode based on the amount of wireless activity on the available channel.
