Abstract

A method and system for conveying contextually relevant information to a wireless client are disclosed. More particularly, a transmitter transmits a diffuse infrared signal to a client having an IrDA compliant communication interface. The transmitter communicates with the client by making a link layer in the transmitter compliant with an IrDA link layer running on the client. To perform communication, data is received at the transmitter from a service provider. The data is formatted into an IrDA compliant diffuse infrared signal and transmitted to the client. The client receives the data and parses it to extract contextually relevant information contained therein. The client may reply to the transmitter if a user of the client is interested in a service offered by the service provider. If the service provider receives a reply from the client, the service is made available to client.
