Network Vision Tower Spotted

[4ringsnbr]

Sorry for trying to download my 300 meg video podcast for the 5th day straight that week :-)

 

I keep the slices attempting to flow on my phone all the time downtown. Doing my part of flooding that tower.

 

If only Sprint hadn't laid off all their performance engineers years ago, they might actually have noticed the high usage. I sent my Verizon buddy a speed test once-- he said "22 kilobits! I'd be fired if my network ever got caught looking like that!" Sadly, that was typical of the past 20 months here...

While we wait on BTR photos...I have photos that I just posted from a site in the Sprint Chicago Market submitted by a S4GRU Member: http://s4gru.com/index.php?/blog/1/entry-73-what-youve-all-been-waiting-forpics-from-a-network-vision-site-in-marengo-illinois/

 

Well im in the heart of Chicago so I really hope this is true. Does this mean that in September the network will be up and running g or do they have to flick the switch and turn it on? If Sprint comes through with a LTE Iphone I will be customer for life if not I will be jumping ship, wife wants the dam phone and you have to keep the wife happy.

Its my understanding that from here forward, each cluster will go live with upgraded 3G and LTE all at once. The Central Chicago Clusters are going to be the last ones. They will be worked on from August through early October. If the entire Chicago market stays on schedule, it will be completely done in October.

One other thing that is killer in BR: the stupid low-e glass they use downtown now-- damn treehuggers! I had jury duty down there-- and you could tell the half dozen Sprint users were lined up along the wall so they could get half a bar of signal from the tower less than 2 blocks away! The energy saving crap kills all the PCS signal! The AT&T and Verizon guys were just sitting in their chairs playing away on their phones and I was standing by the window leaning on the window with my tongue hanging half out trying to get my mouth right to catch a signal-- and I know I was killing the EVDO on that sector trying to pull timeslices.

 

Why would Verizon work but Sprint would not. Both are on 1900 MHz, aren't they?

Verizon runs 2-3 1x voice and 5-6 Ev carriers in their Cellular (850 MHz) here. They also run some Ev in PCS 1900-- but only to keep the speeds up in the busier areas of town.

 

Since buying Alltel, they have the Cellular A side in BR and I think the whole B block PCS.

Correct. Vzw has the PCS B block, 10mhz of AWS, Cell A and of course their block of 700 in BR.

I thought they had 20 MHz of AWS here-- don't they own the entire F block east of the Mississippi? Not that it's worth anything-- AWS with a 400 MHz spread will always be glitchy. They also have 34 MHz of 700 band here too, don't they?

I guess the "RULE THE AIR" motto is really true!

It's 22 Mhz I believe.

FCC Spectrum Dashboard shows:

Why would the 400 MHz FDD offset make AWS "glitchy"? Sure, open loop power control might not be very effective, since uplink and downlink propagation are not highly correlated. But closed loop power control solves that problem. Plus, having longer wavelength spectrum, hence slightly stronger propagation characteristics on the uplink (compared to the downlink) is always nice for exceedingly power limited mobile devices.

The large separation between uplink and downlink causes the power control issues you mention. Also, the differential in signal propogation causes unstable signals at times, especially when transitioning between sectors. Do you know anyone that has T-mobile? How often do they drop calls? (I know alot of that is due to GSM-- such a horrible system for maintaining a mobile voice connection, but even CDMA may have some issues with AWS).
