## Abstract

A system for enabling signal penetration into a building includes a first transceiver, located on an outside of the building, for transmitting and receiving signals at a first frequency outside of the building, wherein the signals at the first frequency do not easily penetrate into an interior of the building. A first up/down converter converts between a first version of the signals at the first frequency and a second version of the signals at a second frequency. The first frequency is higher than the second frequency and the signals at the second frequency better penetrate to the interior of the building and overcome losses caused by penetrating into an interior of the building. A second up/down converter converts between the second version of the signals at the second frequency that overcomes the losses caused by penetrating into the interior of the building and a third version of the signals after transmission from the building exterior to the building interior. A router transmits and receives the third version of the signals within the interior of the building.
