Hi our PC has wireless keyboard and mouse which operate through infra red system,can I use this infra red system to exchange data with mobile having infra red feature, if yes how

Elaborate your ans in detail

Laptop and mobile phone infrared ports generally support IrDA specifications and protocol suites. Infrared wireless keyboards and mice generally communicate with a IR transceiver unit that plugs into the wired keyboard and mouse ports.The communication can be IrDA or a proprietary format. So to answer your question, first it depends on your specific hardware, and second the device would have to have special drivers to support sending data out the wired keyboard and mouse ports to the transceiver unit to transmit all the while it is still functioning to receive the keyboard and mouse input. I've never seen a device capable of this and I can't fathom why one would do this. In this setup, the maximum data transmission rate would be limited by the bandwidth of the wired keyboard port (serial data at 10-16 kHz - see PS/2 technical protocol discussion). Also, most wireless input devices today are RF (radio frequency) and not IR (infrared). Additionally, wired Ethernet (100+ Mbps) and 802.11 RF wireless (11+ Mbps) are significantly faster than commonplace IrDA (~4 Mbps) and don't have the line-of-sight restriction. If both machines do not have an Ethernet adapter (? ), IrDA USB adapters are available.
