      Samsung Network Vision equipment are highly distinct and fairly easy to spot compared to the equipment that other vendors are deploying. Sprint is Samsung's first extremely massive American contract (baring Clearwire) so there  should be no issues in confusing these equipment for another carrier which happens often with Ericsson NV equipment.

      Below are images of Samsung equipment which includes antennas, remote radio units, base stations, and their mounting configurations.

      Given the fact that Virgin has access to Extended Coverage ever since it's Inner Circle plan still now with it's current one at least according to customer service. Shouldn't Virgin be using PRL 55070 like it was with Inner Circle or is 7080 correct? I feel like there's an issue that isn't being paid attention too. Does PRL 7080 have the necessary stuff to make the device roam on Sprints extended partners.

      When Virgin Mobile introduced their Inner Circle plan they added Extended coverage giving them the same coverage as Sprint Postpaid. And a few months ago when Virgin did away with its Inner Circle plan and its iPhone only to the current plan lineup and devices I figured they'd backtrack on the roaming and go back to Sprint only. While they may not have updated their coverage map it would seem they are not allowing roaming as my LG Tribute Dynasty which is compatible with US Cellular roaming is being restricted and blocked post activation. Before hands free activation began I was able to go into the devices network and roaming settings and switch on voice roaming, which worked, it immediately connected to US Cellular, then the hands free activation started which couldn't complete due to no data until I switched on wifi, but after the device rebooted, the voice roaming was turned off and greyed out so it couldn't be switched back on.
      I know this device is capable of roaming, it has band 12 and band 5 for LTE and the CDMA band necessary to roam onto US Cellulars CDMA network, which again it was able to due prior to activation. If Virgin Mobile is going to continue having roaming as an option then it should work otherwise they need to remove it from their coverage map. I've attempted to take the issue up with Virgin but they tell me that they'll help me with any other issue, except roaming. I believe it has something to do with the PRL since it is what determines the devices roaming. I found a old Virgin device from before Inner Circle started, in it was PRL 7080 the same one as it has now, back then Virgin was the home network on Sprint only, no data or voice roaming.
      I don't know where the issue is with this and I'm hoping after filing a complaint with the FCC which has been served that it is either corrected and fixed and roaming starts working, or Virgin removes it from their coverage map if they're not going to allow it. I've asked customer service if the coverage map and the roaming on it applies to current customers or if it was just Inner Circle and they say it does apply to the current plans. If so, and if I have a device that is compatible (LG Tribute Dynasty), why is it being restricted.

      Sprint Nextel revealed their second quarter 2012 corporate earnings in a conference call to their investors today and S4GRU was covering for news on Network Vision.
      Network thinning of the iDEN network is complete, taking 1/3 of Nextel towers off air. The Nextel network was built to support 20 million subscribers, but was only supporting 4.4 million subscribers, so it could easily be thinned without [much] noticeable change in street coverage. Sprint also converted 60% of the Nextel subscriber loss into their Sprint subscriber base. Interestingly, they stated that Verizon has been the biggest poacher of subscribers leaving Nextel, grabbing 50% of former subscribers in the last 4 1/2 years. In that same timeframe, Sprint has grabbed 25%, AT&T 20% and T-Mobile 5%.
       
       
      On the Network Vision topic:
      4 additional cities will launch, including Baltimore, by the end of August.*Edit* Cities were disclosed VIA press release following the conference call. They are:
      Baltimore, MD Gainesville, GA Manhattan/Junction City, KS Sherman-Denison, TX  
      Over 2,000 sites are currently online with 12,000 sites to be online by the end of the year
      Network Vision towers are seeing 10-20% additional voice minutes usage per tower, overnight after activating Network Vision. This will equal roaming savings for Sprint, and ESMR will only increase that savings.
      CEO Dan Hesse confirmed that Sprint will be releasing the Motorola Photon Q "in the very near future." It will be a QWERTY slider "with robust business and consumer features." It will also be sporting world phone capability.
      Several hundred Network Vision sites are waiting for backhaul, and will turn on when the backhaul is installed, several hundred more sites have birds nesting on them and Sprint won't be able to turn them on until the birds leave, according to the conference call.
      Sprint sold 1.5 million iPhones during the quarter, even though other carriers saw slowing of sales with rumors ramping up that the new iPhone would support LTE. 40% of the iPhone sales were to new customers. They also stated that iPhone customers require less customer support and are expected to churn less than customers on other phones.
      Mr. Hesse confirmed that Sprint is not looking to change plans in the near future.
      Things are looking up for Sprint. This quarter saw their highest ARPU and their lowest churn rate to date. They posted a larger loss than Q1, but beat their revenue goals for Q2. For more detailed financial information, check the source link below.

      Here are the Alcatel-Lucent (ALU) Network Vision equipment for Sprint. Their equipment consists of 2x base stations, 6 or 9 Remote Radio Unit (RRU) setups, and 1 standard NV antenna of with connectors on the bottom (4x PCS, 2x SMR). 

      Below are images of Alcatel-Lucent equipment. In these images, you will find Alcatel-Lucent base stations, Sprint Network Vision antennas, PCS 1900 & SMR 800 RRUs, and their configurations.

    • So T-Mobile having last minute business update call at 9am et in the morning....
    • When we get to a finished product, probably the best way to handle it for our Database editors is to keep a Google Doc that we can keep edited.  Then export that to update a SQL Database and then all the markers.  That's probably easier (and safer) than giving everyone access to the SQL database. That's essentially what we did in the past.  It's just we used Fusion Tables as the database that we edited and then exported it into a Fusion Table static data map. Robert
    • Here is a rough draft small demo map with a few MMIMO sites in the greater Seattle area: https://projects.viranifamily.net/s4gru/mysql-maps/?map=mmimo_western_wa This is what most users will see. I will be making performance enhancements in the coming weeks, although the map seems to perform well with all of the datasets I've tested thus far - up to 9,000 pins.   I currently have not had time to make a publicly-available backend for people to fiddle with, but @S4GRU had a chance to take a look at it and can speak to how it works.  
    • Most likely MHF4, or possibly u.fl size ports. I found what look to be u.fl on the T-Mobile Askey board and I am tearing it down after a late snack to find out the same thing. I have a ton of these handy in my lab but you can get MHF4 here and u.fl here with 2 day shipping. It's where I get all of mine and they work great. Just select what type of SMA jack you want on the opposing end in the dropdown.
