Abstract

Disclosed are systems and methods which provide for management of wireless communications through the development and use of link space information. Such link space information provides link-centric information with respect to wireless links of a network to thereby provide a view of the network which takes into account phenomena affecting the wireless links. Utilizing such link space information, automated management of various aspects of a wireless network may be provided, including automated provisioning, management, and/or optimization of network links. Network operations may include use of link space information in providing network management applications such as automatic fault management, automatic performance management, operation advisories, and/or the like.
