Having trouble with trees? WiFi signals can penetrate them, says antenna maker

Typically, WiFi doesn't work if you can't see the remote antenna; and for those trying to deploy Wireless LAN in rural areas or a park in a city, trees are a very effective radio screen - a screen, says WiFi-Plus, which it can see through.

WiFi-Plus has announced a multi-polarised antenna family for non-line-of-sight applications. From first examination of the spec, it doesn't seem to be using the same multi-path technology that will become standard when 802.11n is ratified, but it's comparable in some ways.

"Many antenna makers strive to reject signal that is not matched in polarisation in order to reject noise.  We embrace and gather that signal that the others reject. It is still good, just in a different polarisation.  This is the key to the our superior performance over other antenna," the (rather amateur)  web site claims.

The official announcement  points out that rural WiFi doesn't mean quaint hamlets in agricultural areas. It means "RV parks and camping grounds and hotel hotspots" as well.
