Abstract

Radio apparatuses and methods for MIMO matrix phasing that may be used to toggle and/or weight the amount of MIMO processing based on the detected level of isolation between different polarizations of the system. Also described herein are apparatuses including auto-range and/or auto-scaling of a signal strength indicator to aid in precise alignment of the apparatus. Any of these apparatuses and methods may also include dynamic power boosting that adjusts the power (e.g., power amplifier) for an RF apparatus based on the data rate. These apparatuses may include a housing enclosing the radio device that includes a plurality of pin elements that may act as heat transfer pins and a ground pin for making a ground connection to the post or pole to which the devices is mounted.

First claim

What is claimed is:

1. A method of multiple-input, multiple-output (MIMO) processing in a radio apparatus, the method comprising:
determining an isolation between a plurality of received signals based on reference signals associated with each of the received signals;
matrix processing each of the plurality of received signals based on the determined isolation; and
outputting the matrix processed signals.

2. The method of claim 1 , wherein each of the plurality of received signals has a different polarization.

3. The method of claim 2 , wherein at least two of the received signals are orthogonally polarized.

4. The method of claim 1 , further comprising receiving the reference signals from a transmitter in the radio apparatus.

5. The method of claim 1 , wherein the matrix processing is scaled based on determined the isolation.

6. The method of claim 5 , further comprising determining a scalar for the matrix processing based on the determined isolation.

7. The method of claim 1 , wherein the matrix processing is scaled when the determined isolation is greater than a threshold.

8. The method of claim 1 , wherein a data rate of the plurality of received signals is adjusted based on the determined isolation.

9. The method of claim 1 , wherein the received signals are MIMO signals.

10. The method of claim 1 , wherein each of the received signals is received by a different receive chain.

11. The method of claim 1 , wherein each of the received signals is transmitted by a different transmit chain.

12. A method of multiple-input, multiple output (MIMO) processing in a radio apparatus, the method comprising:
determining an isolation between a plurality of differently polarized received radio frequency (RF) signals;
matrix processing each of the plurality of received RF signals based on the determined isolation; and
outputting the matrix processed signals.

13. The method of claim 12 , wherein at least two of the received RF signals have orthogonal polarizations.

14. The method of claim 12 , wherein the matrix processing is scaled based on the determined isolation.

15. The method of claim 14 , further comprising determining a scalar for the matrix processing based on the determined isolation.

16. A radio frequency (RF) device, comprising:
a housing;
one or more antennas;
a receiver configured to:
determine an isolation between a plurality of received signals based on reference signals associated with each of the received signals;
matrix process each of the plurality of received signals based on the determined isolation; and
output the matrix processed signals.

17. The RF device of claim 16 , wherein each of the plurality of received signals has a different polarization.

18. The RF device of claim 17 , wherein at least two of the received signals are orthogonally polarized.

19. The RF device of claim 16 , the matrix processing is scaled based on determined the isolation.

20. The RF device of claim 16 , wherein the received signals are MIMO signals.
