3. Mobile units future
People are becoming more and more dependant
on their mobile units. Primary people have used
the mobile in social contexts, but today the mobile
is an important tool in our daily work.
• We use if for voice communication and sms (of
course).
• We use it to access company information of
different kinds:
• Mail/facebook/twitter/calendars/google
• ERP system information (order/hours/
plans/docs)
• Control Systems (PLC/Alarms/
maintenace/schedules)
• Geographically spread equipment
(measurement stations/pumps/gates)
• Games
4. Problem
A lot of different company systems exist without a mobile
connection:
• Accounting system
• Different databases
• Internal sharepoint portals
• Control systems
• PLCs
Lot of work and hazzle to make information available to
coworkers (in a secure way)
9. Security
• Lost/stolen mobile
• Can remote-control mobile device and erase important
content on the phone.
• Avoid intruders
• Will always use firewalls, and can also disable possibility
to start inbound connections
• Protocols
• We use SSL and certificates to make secure encrypted
connections between sites and mobile units
