Abstract

A significant portion of the world has no mod- ern communications infrastructure. In addition, a large number of the people in these areas have a very limited income level. Industry for these areas includes agriculture, mining, and forestry. This arti- cle describes a method for providing a low cost ser- vice for basic information transfer to these remote areas. This messaging could support ordering sup- plies, selling product, checking on weather, notify- ing of some emergency or change of plan, or provid- ing some other type of messaging services.

CONCENTRATOR/REPEATER PROVIDES REMOTE VILLAGE LOW COST ACCESS TO IRIDIUM SYSTEM

  A significant portion of the world has no mod- ern communications infrastructure. In addition, a large number of the people in these areas have a very limited income level. Industry for these areas includes agriculture, mining, and forestry. This arti- cle describes a method for providing a low cost ser- vice for basic information transfer to these remote areas.

  The aaicle describes both a new service and a method for providing that service. The service is low cost messaging services for remote locations which have no other phone access or very expensive phone access. The method consists of a concentra- tor with memory that collects messages and trans- mits them over the Iridium System or a similar sys- tem when the system is under utilized. The follow- ing figure describes the process along with equip- ment to support the method. In addition, an exam- ple describes how the system would work.

  The process consists of four steps: input, stor- age transmission, and receipt. In the input step the user generates a message. This message may be text, verbal, or pictorial. The message is then con- verted into an electronic form and compressed if necessary. A simple compression method may just be the standard algorithm used for a fax for trans- mitting pictorial information. Once the data is input (generated and converted to the appropriate elec- tronic form) it is stored until low cost transmission bandwidth is available. The network administration would either per a schedule or real time provide net- work cost or load information that would allow the user to choose a low cost transmission time. When the appropriate transmission time occurs, the system would move the message from storage into trans- mission. Finally, when the message is received it would be converted back to the original format (text, verbal, or pictorial).

  In the example, the user generates a simple mes- sage to have more fert...
