New 4G tech may heat up mobile Network Neutrality debate

Fine-grained network controls that are coming with next-generation mobile technology could make some demanding mobile applications such as video perform better but may also raise Network Neutrality concerns.

LTE (Long-Term Evolution), the fourth-generation (4G) mobile technology expected to be most widely adopted by carriers around the world, is designed to boost wireless data speeds and more efficiently serve subscribers. But along with that standard come others that define the IP network behind the cell towers. One of them, called PCRF (Packet Core Routing Function), will give carriers much more fine-grained control over how well applications and services perform.
