According to writer David S. Bennahum, cellspace is the kind of cyberspace you experience when
equipped with a cellular
telephone that can be connected to the Internet. Bennahum describes being able to receive
e-mail through an air shaft in a subway tunnel, reading the mail on the subway, and sending the
replies back after ascending to the street. Bennahum envisions new services that could be provided
for mobile users, especially one that combined all the map, restaurant, airline reservation and
timetable, rental car, and hotel information into a single site. Already, he notes, there are
special services for travellers providing remote access to corporate intranet. Apart from
services, Bennahum notes one characteristic common to many cellspace travellers: because packet
delivery is relatively slow with today's technology, services or users tend to dispense with the
graphic images.
Bennahum's concept of cellspace is based on experience with his 3Com Palm Pilot, a Novatel
Minstrel modem, and connection to a Cellular Digital Packet Data (CDPD) packet-switched network at
19 kilobits per
second.
