Information handling system antenna multiplexed interface with enhanced extensions
An information handling system adapts to changes in wireless communication protocols and frequencies by modifying a table that defines how wireless networking modules communicate through a wireless controller with antenna modules. In one embodiment, packets are switched between wireless communication modules and antenna modules by reference to an identifier stored in a lookup table of wireless controller. In another embodiment, the wireless controller directs wireless analog signals to between desired wireless networking modules and antenna modules with band pass filters that isolate signals based upon frequency.
1. An information handling system comprising:
a housing;
a processor disposed in the housing and operable to process information;
a memory disposed in the housing and interfaced with the processor, the memory operable to store the information;
plural wireless networking modules interfaced with the processor and memory, the wireless networking modules operable to process the information input as digital values to support wireless communication by outputting analog signals having the information carried at a selected frequency;
plural antenna modules operable to receive the analog signals and send or receive the information as wireless signals; and
a wireless controller interfaced with the plural wireless networking modules and the plural antenna modules, the wireless controller operable to direct information between predetermined of the wireless network modules and predetermined of the antenna modules, the wireless controller receiving the information from the plural wireless networking modules as analog signals and directing the analog signals to desired of the plural antenna modules by setting a band pass filter frequency at each of the plural antenna modules to allow the desired analog signal to pass to the desired antenna module;
a lookup table interfaced with the wireless controller and storing an association of predetermined of the wireless network modules and predetermined of the antenna modules;
wherein the wireless controller applies the association to direct information between predetermined of the wireless networking modules and predetermined of the antenna modules; and
wherein the wireless controller applies the association of the lookup table by setting a band pass filter to direct information based upon a transmission frequency of the information.
2. The system of claim 1 wherein the lookup table further stores one or more antenna settings to tune one or more antennae, and the controller applies the one or more antenna settings based upon the predetermined of the wireless networking modules associated with the information.
3. The system of claim 1 further comprising a wireless management module stored in the memory and operable to execute on the processor to alter the lookup table to adapt to varying configurations of wireless networking modules or antenna modules.
4. The system of claim 1 wherein the wireless controller comprises a crossbar switch.
5. The system of claim 1 wherein the wireless controller comprises a multiplexer/demultiplexer.
6. The system of claim 5 wherein the wireless modules comprise at least a GPS receiver, a wireless local area network transceiver, and a personal area network transceiver.
