How can the Army design its future communications network to meet competing demands at a time of rapidly changing user needs and technologies? As the Army migrates to a new force structure that is knowledge-based and network-centric, the issue of bandwidth, which facilitates communications capacity, has become increasingly critical. Increases in the number of network participants create shortages of bandwidth supply. The authors examine the ArmyOs projected demands for communications capacity and describe steps that can be taken to address the likely gap between demand and available supply.
