When asked about the services <strong>of</strong>fered or intended to be <strong>of</strong>fered <strong>for</strong> mobile scenarios (not<br />
necessarily <strong>for</strong> safety communicati<strong>on</strong>s), most <strong>of</strong> the participants showed an extensive portfolio <strong>of</strong><br />
technologies and services:<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
BGAN, IsatPh<strong>on</strong>ePro2, IsatHUB<br />
Short Burst Data (SBD), RUDICS / Circuit Switched Data, Voice Service, PTT (Push to Talk),<br />
Broadband (Certus Services 22KB/s - 1.4MB/sec)<br />
Internet, VoD, TV multicast and other <strong>on</strong>board entertainment services<br />
SCPC, MESH and STAR (MCPC) soluti<strong>on</strong>s<br />
RPAS / UAV / Maritime applicati<strong>on</strong>s<br />
Remote and Hub equipment<br />
IntelsatOne Flex (<strong>for</strong> high-per<strong>for</strong>mance COTM/SOTM in rail, aviati<strong>on</strong>, maritime and automotive<br />
envir<strong>on</strong>ments); intended: integrati<strong>on</strong> <strong>of</strong> LEO service from OneWeb (up<strong>on</strong> availability)<br />
<br />
Turn-key soluti<strong>on</strong>s <strong>for</strong> mobile <strong>SATCOM</strong><br />
Regarding the provisi<strong>on</strong> <strong>of</strong> services <strong>for</strong> safety communicati<strong>on</strong>s, 70% <strong>of</strong> the resp<strong>on</strong>dents stated that<br />
they either provided them already or intended to do so in the future (see Figure 57). Am<strong>on</strong>g those that<br />
replied affirmatively, some provided more details <strong>on</strong> the current/intended services:<br />
