1. An information handling system comprising:
- a first processing system including a first processor and a first radio, wherein the first radio includes a first output, and wherein the first processor is operable to control the first radio and a shared resource of the information handling system;
a second processing system including a second processor and a radio data interface, wherein the second processor is operable to control a second radio and the shared resource independently from the first processor; and
a radio selector board including the second radio and a radio selector, wherein the second radio is coupled to the radio data interface and includes a second output, and wherein the radio selector is coupled to;
the first output;
the second output; and
a first antenna; and
wherein the radio selector is operable to couple the first antenna to a selected one of the first radio or the second radio.

Abstract
An information handling system includes a processing system with a radio output, another processing system with a radio output, and a radio selector operable to couple an antenna to a selected one of the radios. A radio selector board includes a radio, a selector switch with an input terminal coupled to the radio, another input terminal coupleable to another radio, a control input coupleable to a control module, and an output coupleable to an antenna. In response to a control signal from the control module, the selector switch connects the first radio to the antenna, and in response to another control signal, the selector switch connects the other radio to the antenna.

11. A method comprising:
-
coupling a first output of a first radio associated with a first processing system of an information handling system to a first terminal of a first switch of a radio selector board, wherein the first processing system is operable to control the first radio and a shared resource of the information handling system; coupling a second processing system to a radio interface of a second radio of the radio selector board, wherein the second radio is associated with the second processing system, and wherein the second processing system is operable to control the second radio and the shared resource independently from the first processing system; coupling a first output of the second radio to a second terminal of the first switch; coupling a first antenna to a third terminal of the first switch; in response to operating the first processing system in a first low-power mode, connecting the second terminal of the first switch to the third terminal of the first switch; and in response to operating the second processing system in a second low-power mode, connecting the first terminal of the first switch to the third terminal of the first switch. - View Dependent Claims (12, 13, 14)

15. A method comprising:
-
coupling a first output of a first radio associated with a first processing system of an information handling system to a first antenna, wherein the first processing system is operable to control the first radio and a shared resource of the information handling system; coupling a second output of the first radio to a first terminal of a first switch of a radio selector board; coupling a second processing system to a radio interface of a second radio of the radio selector board, wherein the second radio is associated with the second processing system of the information handling system, and wherein the second processing system is operable to control the second radio and the shared resource independently from the first processing system; coupling a first output of the second radio to a second terminal of the first switch, coupling a second antenna to a third terminal of the first switch; in response to operating the first processing system in a first mode, connecting the first terminal of the first switch to the third terminal of the first switch, and operating the first radio using the first antenna and the second antenna; and in response to operating the second processing system in a second mode, connecting the second terminal of the first switch to the third terminal of the first switch, and operating the second radio using the second antenna. - View Dependent Claims (16, 17, 18, 19, 20)
