Most cell sites (nodes) have battery backup that is good for several hours at full load. Most of the larger carriers, like AT&T, Verizon and Sprint either have small propane powered standby sets at their sites or are putting them in. Because of the increased subscriber base for phone service with many cable providers, there is a push for them to have backup power for their systems as well. I worked on a project at Kohler that used a 5kW propane powered set that provided battery charging to a cable system UPS that was part of a distribution cabinet.
One of our biggest customers is AT&T, who currently has a national program through Generac that is placing standby power at all of their sites. In Indiana alone that is nearly 300 sites, and we maintain all of them.... Dan --- [EMAIL PROTECTED] wrote: > It can be nonexistent, in fact.
