Abstract

Systems, methods, and computer-readable media, for facilitating selection of networks are provided. In some embodiments, the method includes receiving at a user device a first signal via a first channel of a MIMO-enabled network and a second signal via a second channel of the MIMO-enabled network. A first power associated with the first signal and a second power associated with the second signal are identified. The first power associated with the first channel and the second power associated with the second channel are used to determine an undesired connection of the user device with the MIMO-enabled network.

Claims (39)

1. One or more non-transitory computer-readable storage media having computer-executable instructions embodied thereon that, when executed, perform a method for facilitating selection of networks, the method comprising:

receiving at a user device a first signal via a first channel from a base transceiver station (BTS) of a MIMO-enabled network;

identifying a first signal power associated with the first signal received from the BTS;

receiving at the user device a second signal via a second channel from the BTS of the MIMO-enabled network;

identifying a second signal power associated with the second signal received from the BTS;

comparing the first signal power with the second signal power; based on the comparison of the first signal power and the second signal power, determining a measure of closeness between the first signal power and the second signal power;

when the measure of closeness between the first signal power and the second signal power falls within a threshold, then determining that a connection with the base transceiver station is using the first power associated with the first channel and the second power associated with the second channel to determine an undesired connection of the user device with the MIMO-enabled network.

2. The media of claim 1 , wherein the first signal power and the second signal power are within a threshold value of one another.

3. The media of claim 1 , wherein the determination of the undesired connection of the user device with the MIMO-enabled network is based on a power ratio of the first power and the second power.

4. The media of claim 3 , wherein the power ratio is within a threshold value of one.

5. The media of claim 1 , wherein the first signal is received through a first antenna of the user device and the second signal is received though a second antenna of the user device.

6. One or more non-transitory computer-readable storage media having computer-executable instructions embodied thereon that, when executed, perform a method for facilitating selection between a MIMO-enabled network and an alternative network, the method comprising:

receiving a first signal from a base transceiver station (BTS) through a first channel of a MIMO-enabled network via a first antenna of a user device;

identifying a first signal power associated with the first signal;

receiving a second signal from the BTS through a second channel of the MIMO-enabled network via a second antenna of the user device;

identifying a second signal power associated with the second signal; based on a comparison of the first signal power and the second signal power;

determining that the first signal power and the second signal power exceed a similarity threshold; and

based on the determination that the first power and the second power exceed the similarity threshold, selecting and utilizing the MIMO-enabled network for communication rather than the alternative network.

7. The media of claim 6 , wherein the similarity threshold comprises a maximum value of the difference between the first power and the second power.

8. The media of claim 6 , wherein the first power and the second power comprise a value associated with energy per bit to noise power spectral density ratio (Eb/No), signal to interference plus noise ratio (SINR), signal-to-interference ratio (SIR), carrier-to-interference ratio (CIR), carrier to interference plus noise ratio (CINR), or a combination thereof.

9. The media of claim 6 , wherein the first antenna and the second antenna are spaced a distance apart on the user device.

10. The media of claim 6 , wherein the first signal and the second signal are received substantially concurrently with one another.

11. The media of claim 6 , wherein the MIMO-enabled network comprises a long term evolution (LTE) network.

12. The media of claim 6 , wherein the MIMO-enabled network comprises a 4G network that utilizes multiple-in and multiple-out technology.

13. A method for facilitating selection of networks, the method comprising:

receiving a first signal through a first channel of a MIMO-enabled network via a first antenna of a user device;

identifying a first power associated with the first signal;

receiving a second signal through a second channel of the MIMO-enabled network via a second antenna of the user device;

identifying a second power associated with the second signal;

using the first power and the second power to determine a power ratio;

determining whether the power ratio exceeds a threshold, wherein

when the power ratio exceeds the threshold, selecting the MIMO-enabled network for use by the user device, and

when the power ratio fails to exceed the threshold, selecting an alternative network for use by the user device.

14. The method of claim 13 , wherein the first power and the second power comprise a value associated with energy per bit to noise power spectral density ratio (Eb/No), signal to interference plus noise ratio (SINR), signal-to-interference ratio (SIR), carrier-to-interference ratio (CIR), carrier to interference plus noise ratio (CINR), or a combination thereof.

15. The method of claim 13 , wherein the MIMO-enabled network comprises a long term evolution (LTE) network.

16. The method of claim 15 , wherein the alternative network comprises a code division multiple access (CDMA) network.

17. The method of claim 13 , wherein the alternative network comprises a network that does not utilize MIMO technology.

18. The method of claim 13 , wherein the threshold comprises an absolute value of variance from one.

19. The method of claim 13 , wherein the power ratio comprises the first value divided by the second value or the second value divided by the first value.
