T-Mobile LTE & Network Discussion V2

Recommended Posts

The main difference is the call itself... one is (4G LTE) is done in a typical wireless call fashion.... VoLTE is a voice-call over the data side of the network... The "experts" on this forum can pick this up and explain further.    Basically VoLTE allows a more efficient use of the network because the call is treated like a packet of data...    


Also with VoLTE voice traffic is priority over all traffic. So even in congested areas you should be able to make and receive calls with no issues.

Yesterday, WRC and WMPT transitioned to their new channels, clearing some of 600 MHz in the DC area.

Today?  https://imgur.com/a/Pg7Bclb

Got back from the southern part of the state today.  Wow, has T-Mobile lit up.  I locked my phone to Band 71 today, and I've connected to 26 of them so far since Friday, assuming Culpeper and Fauquier are not part of the market.  (They were running before Friday.)  That includes near-constant connection on B71 from about the Fairfax-Prince William County line to home south of Alexandria.

Damn, that's impressive! That's why I wanted T-Mobile to buy Sprint. To light a fire under their behind!

T-Mobile just deployed 600MHz in my area. 
Mine is deployed in my area but it's only a 5 megahertz carrier

Here are t mobile small cells in north Denver off pecos at around 73rdish. There is an actual site off 88th and pecos. Fastest speed ever for me. Yes I was right in front of it. b27fdb514678eb391791b2ffd8c3ca04.jpgd21dbcaab57523a2141cd99a07751798.jpg1120bfd9e46f73273d76f4a28a107d1a.jpg

So band 71 is new here but useless. My phone was staying on band 2 at -120 to 125, then catch band 12 which wasn't much help, and then band 71 didn't help. I wasn't far from the site and no really big obstacles blocking signal. I'm assuming it's still being tested? 8415e388cd540694fcae8418d8476c86.jpga7b0e70b606dc6f33e9bae981278086b.jpg

So here is this site now with it's base station now. Not live yet. It does have the typical GPS antenna that t mobile uses. I'm wondering if this is a new dish site? Also they're three t mobile sites not far from this site. bd9472bee79772fdccf5f0bd650d7d16.jpg227259868e49391fca7a209c17ef833c.jpg

That looks like a T-Mobile 600-ready setup. Dual Commscope antennas.

Haven't seen one like this.  Do you know the logical reason for why carriers have different antenna setups?

Size/weight/structural limitations are the most common reason. Carriers try to deploy bigger/heavier higher-gain antennas where possible and resort to smaller/lighter lower-gain antennas when necessary. 

Carriers also have different setups for different beamwidths (e.g. in my market, Verizon uses different antennas for sites with 90° sector spacing than for sites with 120° sector spacing).

Lastly, carriers may use different antennas that are the same size due to their different gain characteristics. For example, Sprint stocks two different 72" octoport dualband antennas. Their 800/1900 gain figures are 14.7/18.0 for the RFS variety and 15.0/17.2 for the Commscope variety.

      Fierce has a poll posted... and is utilizing a bracket style contest to find out who their readers think is the most powerful person in the telecom industry. Between Marcelo and the pink clad Chihuahua of a man... I give it to Marcelo. I think the final winner should be Masa, it's is a name people know and will get to know more in the coming years worldwide. But for the current poll, it's an easy decision for me!

      T-mobile Ericsson Cell Equipment
       
      For Ericsson markets t-mobile uses what is known as AIR antenna units which have the radio unit integrated with the antenna. This type of setup significantly reduces signal loss from the radio to the antenna since they're both practically next to each other and not sepearated by coax jumper cables like that of a remote radio unit.
       
      Basic Ericsson AIR21 setup
      (Note typically there are 2 Ericsson AIR per sector)

       

       

       
      Ericsson AIR21 + Band 12 700 mhz Equipment
       
      Note the addition of a new low band 700 mhz capable antenna + Ericsson RRUS11 B12 (remote radio units) in addition to new TMA (tower mounted amplifiers) connected to the AIR antenna. The new Ericsson RRUS11 B12 + Antenna addition is for tmobiles band 12 700mhz (L700) deployment.

      With the introduction of the new plans Sprint has announced. I told one of my friends about the $60 unlimited plan and she was shocked yet happy about it. She currently has T-Mobile and there has been times where my Sprint service has out performed her service even in the city with puling up information and out of town...well... you already know how that went. She was talking about switching and stuff but then she sent me a typical article bashing Sprint and I got irritated by it and I had to explain to her that Sprint is not bad at all. These articles are based on past experiences from 3+ years ago. I told her I'm pulling 60+ mbps on LTE but she's worried about Sprint being slow ( because of what she read). Guys give me some advice on persuading her to give Sprint a chance. 
       
      I feel like articles that are being posted is what keeps away customers.  It makes no sense that T-Mobiles 2g network is not spoken about when they are in the news for changes to plans and such. But good ol Sprint makes changes and articles that get posted rips Sprint apart for filth.

      Roger Cheng @cnet appears to have had the most fun out of this, it kind of wrote the story for him I guess, so there is that. Also, just noticed the extra title Q, that is gonna drive some people nuts today. Top lel.

      Am I the only one that likes to look at Verizon's coverage comparison tool. I think it gives a good idea of a carrier's generalized coverage as far as those cities that have been announced. However, it takes a while for it to get updated. I look at Verizon's map and think, no one will ever build an LTE network of that size. When I look at T-Mobile, I see a spotty, spread out network. AT&T is also spotty with a few highways covered here and there. Sprint seems to be more put together as in even if it is spotty, they are in blobs rather than random remote areas.
       
      I've also found a few places that Sprint has coverage in but not Verizon such as in southern Texas.
