3 Product overview
3.1 General
OneBASE™ Pico Node B is a complete pico cell radio base station intended to enhance coverage and increase capacity in 3G (UMTS) systems. The OneBASE™ Pico Node B connects to the UTRAN system using the Iub interface.
If the UTRAN operation and maintenance system (OMC) has integrated support for OneBASE™ Node B, then this can be used for centralized operation and maintenance.
Local configuration is handled with the Local Management Tool – LMT. The LMT runs on a standard portable PC and is connected directly to an OneBASE™ Node B unit through an Ethernet interface.
For remote control it is possible to use an LMT via the same IP network as would be used for used centralized operation and maintenance.
An NTP (Network Time Protocol) Server is required in order to get the correct time in the Node B. Each Node B has an NTP client which fetches the correct time from the NTP Server.
