    Sprint backhaul

    in Network, Network Vision/LTE Deployment

    Posted

    Sprint has two band 41 setups just like how there's two types of pcs 1900.

     

    One is a standard band 41 setup configured for 3 band 41 carriers for a single chain single traditional sector. This is a standard capacity site and will be as configured in most areas.

     

    High capacity sites add another three additional carriers in a new separate chain for up to 60 mhz additional lte bandwith. This will be used in areas where capacity demands it and needed asap. Going from 3 20 mhz carriers to 6 20 mhz carrier requires double the backhaul requirements (1gigabit minimum per site to 2 gigabit minimum) which most of the time entails nearly twice the backhaul costs. We're about paying $1000-2000 to $5000-$7000 a month.

     

    It is a huge cost and a huge waste if they don't even need that much capacity say in a suburban area in comparison to urban zones where three 20 MHz band 41 carriers will easily suffice especially with additional site density via small cells.

     

    Furthermore there's thus nifty new technology called LTE UE Relay. It is what sprint says "use 2.5 for backhaul" as it does indeed use existing band 41 carriers for bandwith.

     

    In simple summary they can be viewed as wireless repeaters though they have one significant advantage. These small cells connect to an existing LTE carrier, use that lte carrier as a backhaul, and then broadcast a brand new signal using that same information of the macro cell but the Small cell doing the Relay will clean up the signal and any errors or interference unlike a repeater where everything is amplified.

     

    Thus it will appear as though a user is connected to a super close and strong macro cell when in reality it is a small cell broadcasting that signal but it itself is feeding off the macro site.

     

    So in an area where outdoors you get a - 100-110 signal, you drop down an outdoor pico cell configured as a relay , it'll connect to a cleaner signal since it's mounted way up and then it broadcasts a brand new even stronger signal.

     

    Instead of a - 110 dBm b41 signal outdoors and non existent signal indoors, users will connect to a strong band 41 signal indoors since that pico cell is broadcasting band 41 lte carriers in that area.

     

    Instead of using dedicated fiber or microwave, it instead feeds off the macro network like a Hotspot. Thus sprint can easily add additional coverage and capacity quickly while they wait for dedicated backhaul to be deployed to the site whenever.

    So say you were connected to one of these repeaters, would it display as the same information (like GCI and PCI) as if you were connected to the macro site? Or would it have it's own numbers? 

    Say hello to the Framily (inexpensive but potentially confusing new Sprint group plan pricing)

    The framily soc was blocked last week. I found out the hard way but bitched to a NSS supervisor til they did it. Framily is effevtively dead in the water. Which sucks i loved selling a tablet for $60 (45+15) instead of the $60plan. So my tablet sales are going to shit.

    So you can no longer add people to the Framily as space opens up? I just had one drop off my Framily. So I am down to nine

    Can the account owner at least add new lines to their Framily still?!?!

    B25 CA?

    in Network, Network Vision/LTE Deployment

    Posted

    To illustrate crudely how B25 is becoming less important where B41 is deployed, see a typical suburban example below:

     

    Tower #1                                                                 Tower #2

     

    B41----------------------->                      <-----------------------B41

    B25------------------------------>     <------------------------------B25

    B26-------------------------------------------->

                                     <--------------------------------------------B26

                                         [-----]      [-----]   Only these people need B25

                                                [-----]          Only these people need B26

     

    This!! ^^^

     

    That is by far one of the best and easiest explanation. B26 was never made to be a primary, strenuous use band. It's like one of those things that's there as "just in case" or a "backup" but shouldn't be used constantly. B25 and ultimately B41 are the workhorses.

     

    This is why optimization is SO critical. If you have a site that's out of sync, you'll wind up having numerous amount of people on B26 but no one on B25 or - if it's deployed - B41. Then you have the mess of people complaining that the network is slow, when in reality it's really not. It's just not optimized to all it could be and you essentially have a full band of LTE - that's actually supposed to have the majority of users on - in the corner twiddling it's thumbs waiting for use.

     

    When you're actually in an area with optimization and full build sites all around, Sprint really does kick butt.  :)

    Apple iPad Air 2 Owners Thread

    in Tablets

    Posted

    So I checked today when I was at the Sprint store...they only have a few 16 GB Air 2's left in stock in the store and the warehouses. 64 GB and 128 GB models in ALL colors are out - can't even be ordered. The store reps didn't have confirmation of this, but think Sprint is discontinuing their sale of the Air 2. :( The Mini 4 seems to be a big push for them, but it's just too small for my needs.

     

    Keep a watch on Swappa. As I've been watching the iPhones, I've noticed the Air 2's pop up on there every so often. However they get snagged pretty quick.

    Karma Go

    So I have now had my Karma for about a month... so here's my review on it.

     

    The day I got it I was so extremely busy I never updated this thread so I decided to get some road use on it first and then update. So right now it's been my business buddy. I keep it so I have a secure connection for my laptops and tablet as I go meet with clients and while I'm working so I don't need to rely on finding/holding onto Wi-Fi. It's one of my biggest pet peeves to use open Wi-Fi.

     

    The moment I turned it on it took me about 5 minutes total to get online with all my devices. After the setup, every time I need to connect it's super fast and easy. I also noticed that every time I looked at the device itself, I never had less than 3 rings (full signal). As for speeds I was first connected to a full NV complete tower with B41 - which I usually get 30-40 mbps on - I pulled about 15 down which is plenty for what I'm using it for. From there on I was mainly pulling 5-12 mbps down, which still is plenty fast for what I bought it for. It also is the advertised speeds. All towers that I were on had minimum of B25/B26.

     

    I have had only one person connect to it while I was working, but everything on that end has worked flawlessly. I received an email letting me know I had a new person connect and I got a free 100 mb. Not bad!

     

    It was well worth the wait for me, and is a great way to give clients and guests Wi-Fi with my business name in without digging into my bucket of data. The battery life is also as advertised though I have gotten 6 hours out of it a couple times. So far, a month in, I'm pleased and hope I can get a lot of use out of it!

    I'm absolutely AMAZED (good amazed, not sarcastic amazed) at the comments on Karma's blog! The speedtest numbers are very, very good and people are giving awesome feedback. Which I was really hoping is what would happen...

     

    Because as we see more positivity, the more and more we can keep saying: "And remember, it's on SPRINTS network!"

     

    I'm in line to receive mine this Tuesday and not a moment too soon either, because I will be able to use it for work the same weekend.  :)

    Hooray! Just one hour ago I received my shipment email that my Karma is heading my way - finally - so I hope I'll have it to use for work on the 14th!?

     

    Also found a great YouTube Review:
