At the recent Communications Developer Conference in Santa Clara, Calif., Sethi said that in the future, travel will be more closely connected with wireless networks. Sethi said, for example, that the road warrior's phone would automatically notify the hotel upon arrival, eliminating the need to stand in line to check in. The hotel customer's assigned room number will appear on the phone's screen, and then the phone would act as a wireless key for the room.
