6. Network Topology • GSMnet and NOMAD solutions in Africa will be interconnected via satellite to a earth station provided by the satellite ISP VSAT NOMAD Sierra Leone VSAT GSMnet GSMnet NOMAD Ghana GSMnet Sierra Leone GSMnet Sierra Leone US LAN/PBX GSMnet Internet • The GSMnet solution in the US along with other fixed office locations will be interconnected via the Internet Satellite ISP earth station Canada LAN/PBX London LAN/PBX The ORG solution will create a private network allowing for all solutions and locations to be interconnected

7. Private Cellular Solution All calls placed and received while registered on the private network will be routed to the SiRRAN network, regardless of its location and the subscribed carrier. All visiting sub calls received while registered on the private network will be routed through the roaming core and then directed to the SiRRAN mobile core. Satellite is only required if no other broadband connectivity is available. Can utilize existing satellite service if subscribed. Any handset can access the system without the need for any application on the device, just as if they were roaming on any network operator Public Telephone Network Roaming Core All calls placed and received outside the private network while registered on a foreign network will be routed through the roaming core, no different than how roaming is handled today. Mobile Data Transactions Standard Handsets SiRRAN GSM Mobile Core INTERNET Enterprise Servers The mobile device can be assigned an extension and be apart of the corporate PBX. All calls placed to that extension number would be routed to the mobile regardless if it was in the private or public network.
