Title : Build a CDMA network for enterprise
Speaker: Dr.赖小荣, Professor
中国普天首信股份公司副总裁兼首信研究院院长

Abstract
A traditional CDMA network consists of a radio network and a core network. The radio network includes BTS (Base Transceiver System) and BSC
(Base Station Controller). Typical core network includes at least one MSC (Mobile Switching Center) and one HLR (Home Location Register). The core
network equipments are expensive. To offset the high cost of core network, telecom operators need to install many BTS and BSC to increase the
coverage and subscribers, but what’s the alternative for enterprises?
Confederal Networks provides a revolutionary way to build CDMA network for enterprises. Starting with a simplified isolated fixed wireless local
loop points, calls among cell phones within the local loop point are routed locally, calls terminate to other local loop points or PSTN are routed
to local PSTN providers. Once there are enough isolated wireless local loop pints and the initial investment has been reasonably returned,
enterprises can consider to escalate their network into the next level, ROAMING. As more and more wireless local loop points keep being added,
enterprises will consider to turn wireless local loop into standard IS41 network by adding MSC and HLR. The Mobility Manager’s hardware is re-
used by MSC, no initial investment has been wasted.
