Upstream/Downstream QoS is handled by the MAC/baseband and the host processor, which it can handle very easily.<br /><br />3. The transmit power is limited by the regulatory domain settings, because FCC and most other domains impose a MIMO penalty.

I corrected the math and the chart indicates the data coverage was for an area of 166,106 square feet. That does seem like a very large area to be covered by a single access point even in a testing setup. I wonder what the testing environment looked like and if that square footage Jenniferhttps://www.blogger.com/profile/15107624786814145982noreply@blogger.comtag:blogger.com,1999:blog-3849138639410953074.post-68141523170399730752011-03-08T15:13:31.231-06:002011-03-08T15:13:31.231-06:00Hi Jennifer,

With 2 radios less than 10 feet apart the strong signal strength of such a close neighboring radio on an adjacent channel will cause tons of interference unless properly shielded. <br /><br />The IEEE standards only dictate a relative signal attenuation (in dB) at Andrew von Nagyhttps://www.blogger.com/profile/12658799453646609565noreply@blogger.comtag:blogger.com,1999:blog-3849138639410953074.post-40579254802838311502011-03-04T16:46:20.847-06:002011-03-04T16:46:20.847-06:00Jennifer, thanks for your time with HP Networking....Jennifer, thanks for your time with HP Networking. I'd like to clarify a few things that you have pointed out in your article above.<br /><br />1. I'd like to say that even though dual concurrent 5GHz may not be suitable for all indoor deployments as yet, that would definitely be the model moving forward a few years from now. Secondly, dual concurrent 5GHz is immensely valuable for Anil@Wyebothttps://www.blogger.com/profile/15867074288082375168noreply@blogger.com
