Wendy is deploying mobile devices to field workers who must travel in rural areas and require constant data service availability. Which one of the following technologies can provide that access?
A. Cellular
B. SATCOM
C. WiFi
D. Bluetooth
Correct Answer: B
Satellite communications (SATCOM) have the widest availability, as they may be used from any region of the world with satellite coverage. For large satellite networks, this covers the entire planet. Cellular signals do travel long distances but may not have constant availability in rural areas. WiFi and Bluetooth are only useful over short distances and would not be appropriate for this scenario.
