Abstract

A method, system, and apparatus for improving the signal strength of millimeter wave signals inside structures received from outside of the structure. In an embodiment, a method includes receiving, at a first receiver external to a barrier, a millimeter wave signal, the millimeter wave signal comprising a wireless transmission protocol. The method also includes converting the millimeter wave signal to an optical or electrical signal using a converted protocol that preserves the original signal's stack layer. The method also includes transmitting the optical signal or the electrical signal on a conduit to a second receiver disposed on a second side of the barrier. The method also includes converting the optical or electrical signal from the protocol back to the wireless transmission protocol and transmitting the converted signal in the original wireless transmission protocol to a wireless device disposed within the structure.
