Infrared is attractive for cordless communications in the officenbecause it is not subject to regulatory constraints, and IRncommunications links can be cheap, and fast, and consume little power.nThe Infra-Red Data Association standard is being developed to supportnwalk-up, point & shoot data exchange-supporting a user model ofnconscious connectivity. The advantages for low cost portable devices arennot just in terms of the hardware cost due to reduced range andncomplexity, but also in reduced complexity of the additional softwarenprotocols-there are fewer devices to deal with, and while the device isninteracting with a peripheral, it is not necessarily required to performnother functions
