Deploy your own private mobile network with OpenBTS, the open source software project that converts between the GSM and UMTS wireless radio interface and open IP protocols. With this hands-on, step-by-step guide, you’ll learn how to use OpenBTS to construct simple, flexible, and inexpensive mobile networks with software.
OpenBTS can distribute any internet connection as a mobile network across a large geographic region, and provide connectivity to remote devices in the Internet of Things. Ideal for telecom and software engineers new to this technology, this book helps you build a basic OpenBTS network with voice and SMS services and data capabilities. From there, you can create your own niche product or experimental feature.

After first experimenting with VoIP in 2004, Michael Iedema worked on IMS proof-of-concept projects until 2007, when he founded the AskoziaPBX project, an easy-to-use telephony system now deployed in countries around the world. After moving on in 2011 to do VoIP related research and development for Ubiquiti Networks, Michael is currently a Senior Engineer at Range Networks, the creators of OpenBTS.
The animal on the cover of Getting Started with OpenBTS is a sun conure, or sun parakeet (Aratinga solstitialis), a medium-sized, brightly colored parrot. Adult males and females are similarly decked out with golden-yellow plumage and orange underparts and face, with red around the ears. Their tails are olive green with blue tips. Juvenile sun conures' plumage is predominantly green, changing to its distinctive yellow, orange, and red coloration as it matures. They reach sexual maturity at two years of age with a lifespan of 25 to 30 years. Hens lay clutches of 3 to 5 eggs; incubation lasts 23 days.
The sun conure is native to northeastern South America. Though its exact habitat requirements are largely unknown, sightings suggest it lives at the edge of humid forests growing in foothills in the Guiana Shield. Common among other members of the Aratinga genus, sun parakeets are social and typically found in groups of up to 30 individuals. They mainly feed on fruit, flowers, berries, and nuts.
They were previously categorized as Least Concern, but recent surveys in southern Guyana and Roraima (a Brazilian state) have shown rarity and possible extirpation. They are endangered and threatened by habitat loss and pet trade trapping. Though they are regularly bred in captivity, the capture of wild sun conures remains a serious threat.
Many of the animals on O'Reilly covers are endangered; all of them are important to the world. To learn more about how you can help, go to animals.oreilly.com.
