NYC Wireless 3

OK finally the punch line Vivato makes equipment that does what they call Wi-Fi switching. Current Wi-Fi standards, like Ethernet, share the medium. In this case the airwaves. They claim to be able to extend signals from meter to kilometer distances. I can't wait for this guy. Here is a snippet from their web site.
Rather than transmit the radio energy in all directions, Vivato's PacketSteering concentrates the same amount of energy into a narrow, long beam. This beam is effectively a high-gain antenna that is formed for the duration of a packet transmission.
Kindof makes sense. It's linux based. The thing has 13 802.11b radios in it. It might be interesting to see what happens when you have 13 'g' radios. They have a planar phased antenna hooked up to all the radios to do the focusing. Sounds like radar. They were out today in central park trying to see what their product would do behind a glass hotel window. ItThe bottom line is they can cover a big area with one unit. Physically it's big and flat. It looks like it measures about 2.5'X3.5'. They are going to plug the damn thing in. We'll see...
