A number of cases have been observed where people who live nearby have used lengths of Cat 5 cable to make a local area network. The problem is that the cable keeps on getting snapped. It is now possible to have a wireless network between your and your friends house. You would not need to install a set of repeaters. Instead any WiFi AP would do. You would need to install a E65 Wlan Network Not Found on the other location. Being a high sensitivity directional antenna, the booster would be easily able to catch the WiFi signals.
