Abstract

Systems and methods for acquiring wireless network performance data comprising a user equipment accessible via a wireless network, the user equipment comprising; a receiver, a transmitter, a first processor configured with software executable instructions to cause the user equipment to perform operations comprising; receiving a data acquisition signal via the receiver, sampling a wireless network signal received at the user equipment in response to receiving the data acquisition signal, generating acquired network data, and transmitting the acquired network data via the transmitter, a server accessible via the wireless network, the server comprising, a second processor configured with software executable instructions to cause the server to perform operations comprising; transmitting the data acquisition signal, receiving the acquired network data; and generating network performance data using the acquired network data.

Claims (52)

1. A system for acquiring wireless network performance data comprising:

a smartphone for sending and receiving data via a wireless network, the smartphone comprising;

a receiver configured to receive and sample signals compliant with a plurality of wireless protocols;

a transmitter;

a first processor configured with software executable instructions to cause the smartphone to perform operations comprising;

receiving a data acquisition signal over the wireless network via the receiver, the data acquisition signal comprising a command directing the smartphone to sample wireless network signals of two different wireless protocols;

sampling the wireless network signals of two different wireless protocols received at the smartphone in response to receiving the data acquisition signal;

generating acquired network data; and

transmitting the acquired network data to a server over the wireless network via the transmitter; and

a server accessible via the wireless network, the server comprising;

a second processor configured with software executable instructions to cause the server to perform operations comprising;

transmitting the data acquisition signal comprising the command over the wireless network;

receiving the acquired network data over the wireless network; and

generating network performance data using the acquired network data,

wherein the wireless network and the server are associated with a first service provider, and at least one of the wireless protocols is a wireless protocol of a network of a competitor service provider.

2. The system of claim 1 , wherein the wireless network complies with a wireless protocol selected from the group consisting of LTE, LTE Advanced, WCDMA, HSPA, CDMA, EVDO, and GSM.

3. The system of claim 1 , wherein the plurality of wireless protocols are selected from the group consisting of LTE, LTE Advanced, WCDMA, HSPA, CDMA, EVDO, and GSM.

4. The system of claim 1 , wherein the smartphone further comprises a GPS receiver; and wherein the acquired network data includes location information of the user equipment.

5. The system of claim 1 , wherein the second processor is further configured with software executable instructions to cause the server to perform operations comprising:

identifying a signal pattern in the acquired network data; and

using the signal pattern to identify a source of each of the wireless network signals of two different wireless protocols.

6. The system of claim 1 , wherein the network performance data is selected from the group consisting of a signal to interference and noise ratio, an Ec/Io, a time offset, a delay spread, a channel condition number, a transmit correlation, a receiver correlation, a RF path, and a channel quality indicator.

7. The system of claim 1 , wherein the data acquisition signal causes the smartphone to sample multiple signals and/or multiple frequencies.

8. The system of claim 1 , wherein the first processor is further configured with software executable instructions to cause the smartphone to perform operations comprising:

compressing the acquired network data prior to transmitting the acquired network data.

9. The system of claim 1 , wherein the generating of the acquired network data further comprises:

a decimation and/or integration step to transform the acquired network data to a desired sampling rate.

10. The system of claim 1 , wherein the smartphone further comprises a plurality of antennas.

11. The system of claim 1 , wherein the second processor is further configured with software executable instructions to cause the server to perform operations comprising;

synchronizing the receiving of the acquired network data from a plurality of smartphones.

12. A method for acquiring wireless network performance data comprising:

transmitting from a server via a wireless network a data acquisition signal comprising a command directing a smartphone to sample wireless network signals of two different wireless protocols;

receiving via the wireless network the data acquisition signal at a smartphone, the smartphone configured to receive and sample signals compliant with a plurality of wireless protocols, the data acquisition signal causing the smartphone to:

sample wireless network signals of two different wireless protocols received at the smartphone;

generate acquired network data; and

transmit via the wireless network the acquired network data;

receiving the acquired network data at the server via the wireless network; and

generating network performance data using the acquired network data,

wherein the wireless network and the server are associated with a first service provider, and at least one of the wireless protocols is a wireless protocol of a network of a competitor service provider.

13. The method of claim 12 , wherein the wireless network complies with a wireless protocol selected from the group consisting of LTE, LTE Advanced, WCDMA, HSPA, CDMA, EVDO, and GSM.

14. The method of claim 12 , wherein the plurality of wireless protocols are selected from the group consisting of LTE, LTE Advanced, WCDMA, HSPA, CDMA, EVDO, and GSM.

15. The method of claim 12 , wherein the data acquisition signal further causes the smartphone to record location information using a GPS receiver; and wherein the generating of the acquired network data further includes incorporating the location information.

16. The method of claim 12 , further comprising;

identifying a signal pattern in the acquired network data; and

using the signal pattern to identify a source of each of the wireless network signals of two different wireless protocols.

17. The method of claim 12 , wherein the network performance data is selected from the group consisting of a signal to interference and noise ratio, an Ec/Io, a time offset, a delay spread, a channel condition number, a transmit correlation, a receiver correlation, a RF path, and a channel quality indicator.

18. The method of claim 12 , further comprising the data acquisition signal causing the smartphone to sample multiple signals and/or multiple frequencies.

19. The method of claim 12 , further comprising the data acquisition signal causing the smartphone to compress the acquired network data prior to transmitting the acquired network data.

20. The method of claim 12 , wherein the generating of the acquired network data further comprises;

a decimation and/or integration step to transform the acquired network data to a desired sampling rate.

21. The method of claim 12 , further comprising, synchronizing the receiving of the acquired network data from a plurality of smartphones.

22. The method of claim 12 , further comprising, adjusting a characteristic of the wireless network in response to the network performance data.
