Brian, If you can do a spectrum scan with an Omni before you decide to deploy one it would be a good idea. You to make sure there is not so much noise that you won't get any advantage of the 900 Band because the noise floor is to high and has to be overcome by the CPE units. An Omni is going to pick up noise from all directions, if you were able to sectorize you may be able to lower the noise floor seen because you aren't looking in all directions. Omni sites make sense from a economic standpoint because you can serve in all directions but if it also creates problems due to noise you gain nothing. You can use a Canopy 900 radio for a spectrum scan. It's not a full blown spectrum analyzer but it will tell you if 900 MHz noise is going to be an issue. Even in rural areas lottery terminals, SCADA, cordless phones, baby monitors and paging transmitters all add to the mix. Horizontal polarization might help also.

I have heard statements from Marlon like "I'd never use a 2.4 omni over such and such gain.....", because of the beamwidth and such. Anyway what are the opinions of the use of the 900 omni? http://www.pacwireless.com/products/omni_900mhz.shtml Brian -- WISPA Wireless List: email@example.com Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/ -- WISPA Wireless List: firstname.lastname@example.org Subscribe/Unsubscribe: http://lists.wispa.org/mailman/listinfo/wireless Archives: http://lists.wispa.org/pipermail/wireless/
