I'm getting up to speed on all the bits and pieces of the Sprint network after getting my Moto X smartphone about 6 weeks ago. I was trying to find some info on the number of EVDO rev. A carriers per sector at a typical site in the PCS spectrum constrained Chicago market. I guess what I'm trying to find out is the effective EVDO air link capacity available to me in the outer Chicago suburbs. I would find it hard to believe if there is only one EVDO carrier serving the whole area of a sector with only 3.1 Mbps theoretical max to share with everyone in my area. Out where I live, a typical tower serves about a 3 mile radius which I calculate a 120 degree sector would cover the users in a 9.4 square miles area (with the 3 sectors of the tower would cover abaout 28.3 sq miles). Ideally I perhaps could use a spectrum analyzer which I could maybe borrow from work, but if someone here has the scoop, it would be very helpful. Now if there is 2, 3 or 4 EVDO carriers per sector with the back haul to match, then I suspect there is some breathing room, and my phone perhaps can jump to the carrier that is least utilized, possibly by looking at SNR if I understand correctly. Also would I be correct to state that one 1X Adv carrier and 3 EVDO carriers would fit exactly into 5 MHz of spectrum? I appreciate any feedback as a brand new poster. Brian
