THE COMPACT MSCFOR RURAL DEPLOYMENTS

WorldGSM™ is the first mobile network designed from the ground

up, to serve rural populations in developing markets – and do it

profitably. We call the approach “Microtelecom” and it is going to

help billions of people make their first phone calls.

standalone Mobile Switching Center in a compact box – easy

to install at the periphery of any GSM network. A single MSC

supports up to 5 WorldGSM™ 500i BSC nodes, serving over 10,000

subscribers and 40,000 BHCA.

 The WorldGSM™ MSC features complete remote management.

All operations & maintenance, including software updates, are

performed through the WorldGSM™ remote OMC.

WorldGSM™ MSC brings all the benefits of being rural optimizedby high-end performance, high-reliability, and compactness, with

simplified installation and security control policies to your network.
