BSC3i High-Capacity
Base Station Controller
Reliability and Power
in a Compact Size

The Nokia Siemens Networks BSC3i 1000/2000 High Capacity

Base Station Controller is a modular, digital switching platform
that connects base stations to circuit- and packet-switched
core networks providing three times the circuit-switched and
four times the packet-switched capacity of its predecessor.

The latest version of Nokia Siemens

Networks’ High-Capacity Base
Station Controller, the BSC3i, offers
vastly improved capacity. Operators
seeking to increase their capacity or
improve their network with the latest
technology will find the BSC3i the
natural choice.

The BSC3i has the capacity to

meet even the most demanding
requirements. Based on the latest
Intel processors, the BSC3i measures
up with any other BSC for CS traffic
capacity and challenges any other
BSC on the market for PS traffic
handling capacity.

The viable PS traffic handling capacity

of the BSC3i is hardly met by practical
limits in live networks and thus avoids
the need to buy new BSCs as your
business grows.
