They have been doing fiber backhaul upgrades on cell site right now. my question is the ones that aren't showing upgrades (network.sprint.com) on the map they will still get the upgraded backhaul when NV hits.

 

Fiber/microwave backhaul is not being done to cell sites until the site is having NV tower upgrade.

 

The stuff on the website u referenced is NOT fiber its only bundled T1 lines being used as patch work temporarily to help the area get by till NV upgrades are done.

Actually I changed my mind and banned DetroitFlyer. I will not apologize for Sprint or make excuses for them. Sprint is months behind schedule in Michigan. So be it. But the first site completed in

OK...I've found the setting. Administrator posts can be liked now.

The update is in progress. I got about half way through over the weekend. I hope to have it finished up in the next few days.   Using Nexus 6 on Tapatalk

There is something going on in phoenix area.. 3g towers will go offline.. ill be running 1x in areas I normally get all 5 bars. Then back 3g full bars half hour later.3g got an upgrade or two at the airport recently I noticed at work some really nice speeds between terminal 3 and 4 by the faa tower...

 

Have you heard any rumblings about lte in the phx metro area? Vzw launched here... att is here... tmobile though not real 4g... better 3g is here as well. I feel like I have been stood up at the dance by sprint... I would hope that as they are upgrading speed and connectivity issues they would also be doing nv upgrades and lte as well.. I would hope...

It would be nice if they were deploying NV/LTE in PHX. You guys deserve it.

 

However, likely what you are experiencing in PHX is related to temporary band aid fixes of additional carriers and additional T1 backhaul upgrades as shown at network.sprint.com.

 

By my sources, NV work has not begun in Phoenix except for some minor backhaul improvements to some sites is beginning. However, many of the vendors doing this work won't be hooking it up to existing services. They are just being terminated there. It will take a visit from Ericsson (Sprint's network vendor) or Alcatel/Lucent (Sprint's NV vendor for PHX) to hook these up.

 

I do appreciate you bringing us up to speed on what you are experiencing there in PHX. Also, thanks for joining S4GRU and :welc:

 

Stay tuned to S4GRU.com for all the latest deployment news. We will be announcing the next NV/LTE city in live chat tonight and the next article will be posted early tomorrow morning.

Just curious, because when I was driving to the airport today (I live in KC) I noticed several towers that had the radio behind the antenna, but there was an antenna right next to it without a radio directly behind it. I remember from the Lawrence drawings this looked like the case like it was done in phases. So my guess these towers are ready they just have to turn on the new antennas and remove the old, or am I completely missing the mark.

 

Yes, the legacy 1900 MHz antennas will remain mounted during a transition phase. My supposition is that -- even after the new 800/1900 MHz dual band antennas and radios have been mounted -- CDMA1X 1900 will continue to operate from the legacy 1900 MHz infrastructure during at least part of that transition phase. So, the mere presence of antenna mounted radios does not mean that you are experiencing Network Vision enhanced coverage -- yet. But I will leave it to Robert to chime in and confirm or correct my supposition.

This is correct. Based on the Lawrence drawings and the Chicago cluster sequencing docs, the antennas/radios (RRU's) appear to go up first, side by side with the operational legacy equipment. New base station cabinets get installed beside legacy base equipment. The NV contractors will deploy antennas, RRU's and base station cabinets over the entire cluster, while leaving legacy equipment active during that time.

 

Once the entire cluster is prepared with tower hardware complete, the next phase will include connecting new enhanced backhaul, preparing additional carriers (as needed for capacity), preparing and programming base hardware/software. New coax runs from the base cabinets to RRU's will be installed side by side with legacy coax.

 

At this time, the NV side will become live and testing will commence. However, most customers will be oblivious. Testing will occur in G Block, even CDMA testing, so as to not interfere with customers. They will start with with 1x testing on G Block, including 911 drive route testing in each cell. Once accepted, they will perform EVDO testing in G Block frequencies. Then finally LTE testing. Then all carriers get configured to their permanent frequency set.

 

Once everything is tested and confirmed ready, the switch over will begin. Legacy systems are disconnected and new NV configuration goes live. Over the entire cluster. This is likely when Sprint customers will notice something different is going on with how the network is performing.

 

In most cases, there are two or three clusters being worked on in a market at any given time. Each cluster takes about two to four weeks to complete, based on size, number of sites and complexities. The number of clusters in a Sprint market is highly variable based on the density population and coverage of each market.

 

After all the NV sites are confirmed operational, legacy equipment will start to be decommissioned and removed. This is exciting stuff to me. I have an article planned on this subject. Hopefully I can get to it this week.

Question Will Sprint continue to use T1 or switch to fiber to the tower once NV is completed?

I would think that Sprint will switch to a combination of fiber/microwave backhaul after NV is complete. There is no purpose of keeping T1 lines when fiber/microwave backhaul is present.

T1 is extremely out dated technology. It is not efficient in our high speed and high data use market.

Fiber and microwave only for NV sites. There may be a few exceptions, but I hope not many!

Exceptions would probably be in smaller towns.

I'm thinking exceptions would be sites that cannot get fiber, nor a microwave line of sight established. There are lots of rural canyons and valleys in the West where this could occur. Also, there could be places that temporarily cannot get the fiber or microwave backhaul they need. But will be able to in a few months.

Being in between Mass and NYC sucks.

 

It's similar to being between LA and Dallas, except we have beautiful mesas and mountains. And the taxes are lower. :tu:

Tonight we announced the newest market: South Bay, which includes San Jose, Santa Clara, Cupertino, Mountain View, Santa Cruz, Watsonville, Salinas, Monterey, Gilroy, Hollister and Morgan Hill.

 

Here is the map...http://s4gru.com/index.php?/gallery/image/107-sprint-market-map-south-bay/

 

We will be announcing the next two markets at once at the Live Chat on Thursday night...http://s4gru.com/index.php?/calendar/event/2-live-chat-two-nvlte-cities-to-be-announced/

 

Columbus, Ohio please

I'll let Hesse know that you placed an order for a Columbus at the drive through window. ;)

 

Would you like fries with that?

For the size of the South Bend market, I think you will be quite happy about its location in deployment schedule. Stay tuned.

      Network Vision/LTE - New York City Market

      By Paynefanbro · Posted

      A new apartment building in my neighborhood is getting a 4G/5G DAS installed. No idea if it's going to be carrier agnostic or if it's going to be just for one carrier. The antennas they are using cover the full range of spectrum from 600MHz-4.9GHz so no telling by equipment alone. I noticed a ton of Cat6E ethernet being run in the garage a couple of days back and then I saw a guy running the ethernet through the ceiling yesterday and didn't think to ask what for until I noticed this antenna this morning mounted on a wall outside near the ramp but with nothing connected to it at the moment.     The garage attendant told me that the phones that are provided to them by the parking management company are on Verizon and they're the only carrier without coverage down there so the building management told them that they're "installing something to fix it". So as far as I know, this will work on Verizon but I'm curious to see who else will get a boost too. — — — — — Without exaggerating, I have mapped a new at least one new small cell on my way to work every day this week. I don't know who the regional network managers for NYC and Boston are, but other cities need to take a page from their book about small cell buildouts. And it's not just upgrades of existing small cells, it's new ones too. Not to mention pings near 10ms on all of them.
