I have observed two recent chages of PC hardware. One is the gradual replacement of CRTs with flat screens. The other is the proliferation of radio transceivers for wireless mice, keyboards and LAN networks.
Now, I ask myself, would it be possible to cut the final cord which connects the PC to the screen and replace it by another radio device?
I suppose that the transmission of the raw, uncoded signal would call for a tremendous bandwidth, but what if one puts parts of the graphics board electronics plus some RAM in the screeen itself and just transmits high level commands like updates and translations?
I can envisage that the latter approach would make it possible to limit the necessary bitrate over the radio interface, but I really have no idea of the order of magnitude of the necessary bitrate.
Is there anyone out there who knows or could make an educated guess what is the bitrate of the traffic from the CPU to the graphics adapter? Are there any software tools (like profilers) that could be employed to collect the necessary data or would hardware maesurement be the only option?
I realize that the necessary bandwidth probably depends on the application being run on the computer. For some advanced PC games, the bitrate might be too high to be comfortably accommodated in the available radio spectrum, but what about more utilitarian applications?
