Actually G mode works better than that. We have clients with -80 dB and they can pull a steady 10 mbps on a X2 cloaked channel (10 MHz of RF bandwidth). Even at -85 dB they can still pull 5 mbps and burst to 10 mbps. Of course these results are with Atheros cards. I have no idea about other

There is nothing wrong with an omni if the users are all around it. You get better signals with a sector but a microcell is the perfect place for an omni. The fact that your current sites can see each other is awesome and you are part way to achieving a Mesh. Lonnie On 2/4/07, George Rogato
