A communication system providing wireless communication among wireless users through a number of cellular base stations. At least one of the base stations is a mobile base station in which low and high speed wireless transceivers are mounted on a temporarily stationary mobile vehicle such as a truck trailer or a truck. The system includes at least one connecting station with a millimeter wave wireless transceiver in communication with a fiber optic or high-speed cable communication network. The transceiver is adapted to communicate at millimeter wave frequencies higher than 60 GHz with another millimeter wave transceiver at one of the cellular base stations. Each of the base stations serves a separate communication cell. Each base station is equipped with a low frequency wireless transceiver for communicating with the wireless users within the cell at a radio frequency lower than 6 GHz and a millimeter wave wireless transceiver operating at a millimeter wave frequency higher than 60 GHz for communicating with another millimeter wave transceiver at another base station or a millimeter wave transceiver at said at the connecting station. The base stations are also equipped with data transfer means for transferring data communicated through the low frequency wireless transceiver to the millimeter wave wireless transceiver and for transferring data communicated through the millimeter wave wireless transceiver to the low frequency wireless transceiver. In preferred embodiments the system is a part of a telephone system, an Internet system or a computer network.

The present invention is a device, which illuminates light inside of a tractor trailer truck van and other loading vehicles at a loading dock during loading and unloading procedures. As professionals working with such vehicles understand, natural lighting is simply not enough to prevent serious loading and unloading accidents, primarily at the deep end of the truck trailer van body. The loading dock spot light of the present invention with its short body design helps prevent fork trucks from hitting and destroying it. The overall short body of the light structure is designed to stay out of the primary main path of the fork truck traffic, allowing the light emitted from the light bulb to just peek beyond the loading dock door seal edge. The present invention is a simple mechanical device, which reduces loading dock operator confusion during loading and unloading operation, maintenance, and repair.

Bulk material storage units that can be placed on flatbeds that can be hauled in various manners, including rail cars or trucks, to the destination and removed from the flatbed for temporary storage at the destination, freeing the transportation mode, e.g., rail cars or trucks, to be used elsewhere. Embodiments of the bulk material storage unit of the present invention replace rail hopper cars or truck trailers to hold the bulk material during transportation as well as provide temporary storage at the desired location, e.g., the origin or destination, without tying up transportation resources.
