LANs' high data rates go  through concrete walls by
microwave Wall Couplers


LAN installation with network segment behind a concrete wall

NO DRILLING, NO CHISELING,
NO BUILDING CODES TO WORRY ABOUT!

Wall and Ceiling Couplers connect your LAN temporarily or permanently through  walls and floors. Transmit your data by Ethernet, Token Ring with any communication system in a license-free public (ISM) frequency band. Only microwatts of coupling power data goes through feet of concrete, secure of interference, intercept and jamming, just like a cable. With a camera attached, a clandestine surveillance system can be quickly placed. See next page for WiFi and WiMax coupler applications.
