BGAN has global coverage, but a high cost
per Megabyte transferred. Good for low or high bandwidth SCADA sensors or other monitoring equipment.

Each solution will create a high-speed satellite link to pass information from the SCADA devices to any IP address on the Internet. A satellite dish will have low monthly service fees, but dishes are bulky and IDU's (In Door Units) are not designed for outdoor enclosures or weather. A BGAN terminal solution is extremely portable, uses very low power (under 6 watts), is made for extreme weather, but has the disadvantage of higher costs for transmitting data. However, if a SCADA application is only transferring 7 MB's a month, BGAN service fees will be $39 a month and $6.50 per megabyte transferred. More or BGAN Satellite Terminals

If the monitoring to be performed is not bandwidth intensive, a BGAN terminal
may be a preferred solution for these reasons:
 A BGAN terminal operates globally (except for the poles) for up to 492kbps up/down speeds.
A BGAN terminal uses very lower power (6 watts in idle mode. 36 hours on internal battery).
A BGAN easily survives in sever winds that would misalign a satellite dish.
Being "L band" a BGAN has almost no rain fade, and can take 25mm of ice before transmission issues.
A BGAN has Auto-On and Auto Power-Cycle, for resolving remote errors or power issues.
BGAN Service Plans can pool multiple BGAN Units under the same account with one bulk fee instead of
multiple individual accounts. More on BGAN SCAP Plans.
A BGAN low profile, helpful in reducing theft or vandalism.
A BGAN low wattage means local power sources/Battery Banks can be smaller.
Many SCADA sensors can be dialed down to transmit less often, or smaller amounts of data making
the more expensive BGAN service more viable.
