LTE – What will it do for a Utility

LTE promises a single long-term network and technology approach for broadband connectivity to nearly all of Consumer’s distributed field assets

Avoids the duplicative costs of geographically redundant, purpose-built networks by integrating the communications of:§ Meter Collectors§ Substations§ Pole-mounted and remote intelligent devices§ Field workforce

� Critical Mobile Data initially� Future Land Mobile Radio replacement

§ Distributed Energy Resources§ Enterprise Voice and Data§ Video Surveillance

* Traffic for these applications is only between two substations connected with transmission line. This traffic must be designed to be only single hop. Thus the corresponding delay requirements must be considered only single hop. All other delay requirements may have to be satisfied over multiple network hops.

Extreme reliabilityand delay requirements that Broadband Wireless generally will not support for awhile

Applications that can be supported for the near term over an LTE Private Broadband Wireless Network
