  1. What speeds are you seeing at -107dBm? I would think it would be around 5-8Mbps. LTE is a totally different technology than CDMA/EVDO so it will work down to -120dBm. Your speeds look good. I would expect to see a maximum speed of around 26Mbps down and 9Mbps up.
  2. Hi Robert, Thanks for the info. Clearing the Nextel spectrum makes sense why the 800MHz RRH was powered off. This means the LTE RRH was powered on, but I had no was to test whether it was radiating. The site was: 25 Brigham St, Westborough, MA 01581.
  3. Sprint recently upgraded one of its towers in the center of Westborough, MA. I went and took some pictures which I uploaded to my website, www.danlampie.com, along with a quick article about Network Vision. I don't have any performance information but it does apear that Sprint is going with narrower beam antennas...probally 65 degrees. This should help increase the SNR, at the expense of reduced coverage in the nulls where the antenna patterns overlap. This is an Alcatel-Lucent market and they installed three RRH per sector, so I was thinking two RRH for PCS and one RRH for 800MHz. It appeared the only two (the PCS band) of the three RRH were powered on, so I am thinking that 800Mhz 1X advanced carriers would be coming a little bit later down the road. The old coax was cut, but the old antennas were still mounted. I wonder why the old antennas were not removed when they were already doing work on the tower.
