FTAS Network Management System

FTAS Network Management System (FTAS-NMS) is the command center for the entire DAS network.  With a full view of the DAS network and its components, FTAS NMS provides at a glance the current health status of the network, notifies staff when attention is needed before impacting users, and makes adjustments to individual elements to optimize performance. 

Authorized users can access NMS data and received notifications over mobile devices additional to NOC terminals.

As the network expands or changes, FTAS-NMS can remotely reconfigure the network and elements to add/change supported frequencies and upgrade network software.

All FTAS active products and components are equipped with element management capabilities, controlled centrally via FTAS NMS, via web interface.

A trusted in-building wireless expert specializing in public safety communications for public and commercial infrastructures, CellGain Wireless provides turnkey solutions, consulting and integration services, and next-generation fiber-to-antenna DAS products to deliver performance, speed, and efficiency for your wireless communications with confidence.
