Dave, Frank was kind enough to send me a copy of the patent application. Thanks again, Frank. Here is what I gather: The users transmitter can send up to 100 G/sec via a collimated laser beam to the central transmitter. So far, so good. This is readily doable. The central transmitter can direct a laser beam in either a vertical or horizontal plane to a users receiver within a 360 degree arc. Transmission can utilize DWDM wavelength multiplexing. It therefore appears to me that a rotating mirror is not used at the transmission site. It is either an array of fixed mirrors, or a MEMS switch. If fixed mirrors, it would be a nightmare to set up and maintain. If MEMS, they better have some great software to go with that. So far, nothing unique here. What I do not see described is the transmitter. If you have 24 clients per sector and four sectors, that equals about 100. One hundred transmitters times 100 G per transmitter equals 10 Terabits/sec. Try swallowing that! Better yet. Figure out how to broadcast that beast. (I'm assuming symmetry). The patent application is silent on the central transmitter/receiver technology. Isn't this the unique part? Jack Hutchison
