This is necessary to identify, localize, and correct errors or faults in the network. Each device within a wireless network should be monitored for troubleshooting or performance. All LMDS devices collect and report statistics pertaining to traffic throughput, boundary condition violations, and management activities.
Configuration Management
This is necessary in order to provision, inventory, initialize, and back-up network resources. The LMDS equipment should be auto-discovered when new equipment is added to a node. This minimizes the amount of provisioning needed to install or upgrade equipment.
Accounting Management
This is necessary to collect and process billing information. Each manageable node in the wireless portion of the network should maintain a collection of statistics that can be accessed by a third-party billing system as input. Users should be identified on a per-network user basis.
Performance Management
This is necessary to collect, filter, and analyze network resource statistics. There are a number of parameters that should be monitored and configured on each network node, from T1 traffic throughput to output power level. The management station should monitor these parameters and adjust them to increase performance.
Security Management
All information transmitted through the wireless environment must be encrypted between each node in the network. The security-management function should automatically generate and coordinate the keys used to encrypt and decrypt, as well as to authenticate users.
The management application at the base station should not be a stand-alone management application. It must provide a mechanism to populate the cell-based information in the node's management information base. For the next few years, dedicated platforms may be required to provide end-to-end management of the complete LMDS system.
