transmitting, by the client device to a server, motion detection information indicative of the motion of the object.

39 . The method of claim 31 , wherein the access point device is not configured to detect motion of the object in the space.

40 . The method of claim 31 , wherein the wireless communication network is a wireless local area network (WLAN), and the set of wireless signals are transmitted from a wireless access point (WAP) according to a wireless network standard.

41 . The method of claim 39 A, wherein the wireless communication network is a Wi-Fi network, and the wireless access point is a Wi-Fi access point.

42 . The method of claim 31 , wherein the motion of the object is detected by operation of motion detection software on the client device.

43 . A client device in a wireless communication network, the client device comprising:

a processor; and

memory comprising instructions which, when executed by the processor, cause the client device to perform operations comprising:

obtaining channel information based on a set of wireless signals transmitted through a space, from an access point device in the wireless communication network, to the client device; and

detecting motion of an object in the space based on the channel information.

44 . The client device of claim 43 , the operations further comprising:

transmitting to the access point device a request for the access point device to transmit the set of wireless signals.

45 . The client device of claim 44 , wherein the request comprises a wireless standard protocol message including at least one of:

a null data packet frame;

a beamforming request;

a ping; or

standard data traffic.

46 . The client device of claim 43 , wherein the channel information comprises channel state information.

47 . The client device of claim 43 , wherein the channel information comprises beamforming dynamic information.

48 . The client device of claim 43 , wherein obtaining the channel information comprises:

receiving the set of wireless signals from the access point device; and

processing the set of wireless signal to obtain the channel information.

49 . The client device of claim 43 , wherein obtaining the channel information comprises:

receiving the channel information from the access point device.

50 . The client device of claim 43 , the operations further comprising:

transmitting, to a server, motion detection information indicative of the motion of the object.

51 . The client device of claim 43 , wherein the operations are performed by an operating system of the client device.

52 . The client device of claim 43 , wherein the operations are performed by an application running on the client device.

53 . A non-transitory computer-readable medium comprising instructions that, when executed by data processing apparatus, perform operations comprising:

obtaining, at a client device in a wireless communication network, channel information based on a set of wireless signals transmitted through a space, from an access point device in the wireless communication network, to the client device; and

detecting, by operation of the client device, motion of an object in the space based on the channel information.

54 . The computer-readable medium of claim 53 , the operations further comprising:

by operation of the client device, transmitting to the access point device a request for the access point device to transmit the set of wireless signals.

55 . The computer-readable medium of claim 54 , wherein the request comprises a wireless standard protocol message including at least one of:

a null data packet frame;

a beamforming request;

a ping; or

standard data traffic.

56 . The computer-readable medium of claim 53 , wherein the channel information comprises channel state information.

57 . The computer-readable medium of claim 53 , wherein the channel information comprises beamforming dynamic information.

58 . The computer-readable medium of claim 53 , wherein obtaining the channel information comprises:

receiving, at the client device, the set of wireless signals from the access point device; and

processing, at the client device, the set of wireless signal to obtain the channel information.

59 . The computer-readable medium of claim 53 , wherein obtaining the channel information comprises:

receiving, at the client device, the channel information from the access point device.

60 . The computer-readable medium of claim 53 , the operations further comprising:

transmitting, by the client device to a server, motion detection information indicative of the motion of the object.
