SC and ST
SCs and STs are CHE used by so called ‘straddle’ operators. Straddle container stacks are different than FEL/RTG stacks
in that containers are not placed immediately adjacent to one another. They are stacked from 2-high or 3-high creating
long rows of containers separated from each other by about 7’. An SC and an ST are shown in the following photo.
Neither WhereNet nor PACECO have installed any equipment (yet) on an SC/ST. The installation, however, is expected
to be straightforward. The PTIU and WNC will be installed at the top of the SC/ST. It will most likely be necessary to
raise the WNC’s GPS antenna, WiFi/RTLS antennas, and compass relative to the possible point of installation of the
WNC enclosure. As in the case of the RTG, the necessary brackets to do this will be the responsibility of the customer.
A block diagram of the components and connectivity of the Gen2 hardware is shown below.
