Indigo Wireless is a GSM mobile carrier in rural America. When it was founded, the company decided to host its switching services with a major wireless technology company, which freed up funds for investment in customer service.
"The true cost of running a network," says Indigo Vice President Dave Tews, "includes the people, benefits, training, the power and the high-quality technical infrastructure required. If you really look at the numbers, you find that the hosted solution is the way to go."
It was generally satisfactory – but the two companies were hardly a perfect match. Indigo was a fast-moving small company. The service provider was a multi-billion-dollar global giant. When issues arose, it was hard for Indigo to get answers.
A search for alternatives led to Globecomm, and we began working to move their service to our 100% IP-based switch with GSM and CDMA support for 2G, 2.5G and 3G services. It was a complex transition, because Indigo wanted to introduce new value-added services right away. So we began hosting the new services while voice and data were still being routed through the old provider's switch.
In the final configuration, traffic from Indigo's base stations and controller flows over fiber to our Mobile Switching Center, which handles all switching and services, and hands off call duration, service and billing data to Indigo's billing system. Indigo customer service staff provisions and maintains services on the switch using a Web interface that we also designed and host. Customers never see the hand-offs: they just know that their small, rural carrier offers a level of service that only the giants can usually afford.
