The Universal Wireless Monitoring System (“UWMS-01”) enables Sprint to monitor and control its
network devices (“Devices”) such as repeaters and DAS remotely and wirelessly. Due to its universality,
any HTTP-based devices with standard Ethernet interface can be connected to the UWMS-01. Using the
UWMS-01 Sprint will be able to access the Devices connected to the UWMS-01 to monitor them or
change their parameters without visiting the physical site. This wireless monitoring and control
capability enables Sprint to proactively diagnose and troubleshoot problems remotely even before a
customer complaint is received. This translates into less network management costs and increased
customer satisfaction.
This means anytime, anywhere access to Sprint’s Devices from everywhere.
- Higher data throughput using 1xEV-DO Rev. A wireless module
- Managing multiple devices (up to 8 repeaters or 32 DAS remote nodes) simultaneously
- Built-in 10/100 Mbps switching HUB
- Eight Ethernet ports
- Conversion of dry contact alarms to SNMP alarms
- Tested compatibility with the following Devices:
ADRF Repeaters, Andrew ION™-B & Node-A Repeater, Dekolink Repeaters, GS Teletech Repeaters,
ADC Fusion®, MobileAccess SC-450, SK Telesys Repeaters, and R-tron Repeaters.
