This easy-to-use dongle meets all the specifications required for Infrared Data Association (IrDA) compliance. The USB adapter has inbuilt IrDA transceivers which efficiently communicate with signals or infrared samples within a cone which has an off center, half angle of 15 degrees. As a result, the adapter has a viewing or reception arc of thirty degree (approximately). The minimum irradiance of the device is maintained such that signal visibility is attained up to one meter. The maximum irradiance attained by the adapter does not overwhelm a receiver placed at close distance. The average operational range of this adapter, therefore, is close to 0.6 meters.
