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 radio apparatus for transmitting radio frequency (RF) signals, the apparatus comprising:
a housing having a front and a back, the back adapted for mounting to a post;
radio circuitry for transmitting and receiving RF signals housed within the housing;
a plurality of more than 10 cooling pins extending from the back, wherein the pins are arranged to produce a turbulent airflow between the back of the housing and the post;
a grounding pin extending from the back and configured to form an electrical ground connection between the post and the radio circuitry; and
an indicator on the front of the housing configured to display an auto-scaled signal strength indicator.

2. The apparatus of claim 1 , wherein the cooling pins have a length that is 15 mm or less.

3. The apparatus of claim 1 , wherein the back of the housing comprises aluminum.

4. The apparatus of claim 1 , further comprising a power amplifier within the housing.

5. The apparatus of claim 1 , wherein further comprising power boost circuitry coupled to a power amplifier within the housing, the power boost circuitry adapted to operate the power amplifier within a linear range as the power amplifier is operated at different levels for different data rates.

6. The apparatus of claim 1 , wherein the cooling pins have a diameter of between about 1 mm and 10 mm.

7. The apparatus of claim 1 , wherein the cooling pins are arranged in rows.

8. The apparatus of claim 1 , wherein the cooling pins are configured to have a plurality of different heights between about 2 mm and about 15 mm.

9. The apparatus of claim 1 , wherein the indicator comprises a plurality of LEDs arranged as a bar display.

10. The apparatus of claim 1 , further comprising circuitry within the housing configured to determine an ideal signal strength and to normalize an actual signal strength to the ideal signal strength for display by the indicator.
