The final step for LTE in the business world is to function as a truly "private" network. This means communications within a given area is not transmitted back to a central hub, but rather lives within the enterprises' confines. The reasoning for this is threefold:

- A private, in-building LTE network can function as a strong backup to fixed networks, and this capability is already being explored at both the enterprise and consumer level.

- Demand is growing for more mobile, enterprise-class applications, from real-time security surveillance applications to high-bandwidth productivity applications, such as WebEx, Skype and IPBX apps, as well as enterprise-specific LTE devices, like 's .

- The ability to bypass LTE "bottlenecks" by remaining on the in-building network means that no matter how congested the macro-level network becomes, the enterprise LTE grid remains accessible.

In the WiMax world, private network examples already exist through providers like Alvarion, but WiMax lacks the application and user pool to really drive adoption forward. For LTE, "killer" enterprise applications are coming, and soon.
