However, I'm curious how location tracking changes to adapt to transmit beam forming, as executed by some one like Ruckus wireless or even Xirrus, since they use arrays of what essentially amount to directional antennas in a circular pattern.Anonymoushttps://www.blogger.com/profile/11507295496129635022noreply@blogger.comtag:blogger.com,1999:blog-3849138639410953074.post-85301781874009932342010-03-15T08:59:17.433-05:002010-03-15T08:59:17.433-05:00Good topic Jennifer.

It also is necessary if you wish to do any sort of tracking by signal location in a tri-lateration system to see the receiver reliably. With a single Sector Panel antenna you need to be in the antenna beam, which is by definition narrow and directional. If you are not in the beam, you will not be seen nor be able to L-com Global Connectivityhttps://www.blogger.com/profile/01456747776924047135noreply@blogger.comtag:blogger.com,1999:blog-3849138639410953074.post-81070004244441637812010-03-02T07:16:37.183-06:002010-03-02T07:16:37.183-06:00Jennifer,

After everything was deployed, calibrations completed what was notice is that client tracking around the cell boundary of a directionals were sadly skewed. <br /><br />The arguement was made to replace the 1231 with 1131. The goal here was to have all the same APs with the same antenna andUnknownhttps://www.blogger.com/profile/14844197521926034842noreply@blogger.com
