This document discusses the potential for software innovation in mobile networks by adopting a more flexible, software-defined approach inspired by the internet. It argues that current mobile network architectures are antiquated and rigid, inhibiting innovation, while the internet has thrived on open standards and flexibility. The OpenBTS platform is presented as an example of a new type of mobile infrastructure that uses software to implement network functions from layers 1-7, allowing for more rapid innovation, protocol agility, and new business models like IoT applications.

Editor's Notes
- #4: Before the Internet reached critical mass in the mid 1990’s the world was dominated by proprietary network architectures defined by large companies who controlled the standards and deployment scenarios. That changed when small companies like Cisco emerged and embraced the diversity that a layered model of networking with rapid innovation at every layer by a large number of companies, mostly small startups, that created Ethernet, Token Ring, FDDI, and higher layer technologies such as XML, HTTP, RTP, and SIP.
- #7: The RANGE software defined architecture enhances cost reduction while opening the platform to third party innovators. RANGE has access to this innovation and can, if it chooses, incorporate the best innovations directly into our software.
- #9: Current mobile infrastructure is also very inflexible, proprietary, and hardware oriented, requiring lengthy and expensive upgrades entirely orthogonal from the internet concepts around user or application specific bucket testing and/or fast, frequent service enhancements.
