Ruggedized Mobile Computers
Some mobile professionals need a system for managing and
communicating information from the field, in environments that may
require special ruggedized features to protect their computers from
extreme temperature, humidity, and physical punishment.
Construction, public service, distribution, repair service, and utilities
are some of the environmentally demanding professions that may
require rugged mobile computers that can withstand stresses. IBM
offers computers (not ThinkPad Systems) for these environments.
