    Band 71 vs band 12?

    For those who have had a chance on band 71 How is it compared to band 12? Do you guys see better coverage indoors and better distance coverage. Curious to know since not many YouTube videos show anything about band 71. Thank you

    For coverage they should be about the same. The reason for this is that the uplinks for the two bands are adjacent. In order to avoid having a guard band between 600 and 700, they reversed the normal up-is-low, down-is-high pattern and put the uplink on the higher side of the band. The uplink is generally the weaker link in the chain.
    Now, for capacity, 600 should be much better because the minimum license block T-Mobile has is 10x10 and they have 20x20 in most places. Also, the combination of 600 & 700 may allow T-Mobile to become a little less conservative with one or the other. Right now, they are extremely conservative with 700, using only the lowest power and smallest cell sizes to get the job done. After 600 is running, they may just get a bit "wild and crazy" with 700 and up the gain and antenna tilt to get better coverage. (Might happen).

    Except for some bigger cities, right now T-Mobile seems to be focusing their 600 efforts on areas where they lack a 700 MHz license. So, there's not at lot of combined 600 & 700 service. Eventually this will change.

    Okay little confused if the two bands having same coverage length ... How is Verizon band 13 able to penetrate buildings better? I understand it’s 700 MHz block c and T-Mobile band 12 is 700 MHz block A.

    Antenna tilt, site density, site placement, etc.

    Band 13, being 10x10, I feel let them be more brave with covering more area per sector than T-Mobile currently does with their setups.

    Add that TMO has only done one sector per cell site on B12 vs vzw has done 3 sector's same as att

    Are they adding 3 sectors for 600 MHz? I wonder why they didn’t do the same with 700mhz

    They do one to get coverage going faster and Cheaper. For B71 I don't know

    So are they going to add the extra sectors later on or we just stick with one sector

    I'm not sure where thotguy31 observed band 12 only being on one sector per site. In my time looking at T-Mobile sites, virtually all b12 sites have had b12 added to each existing sector. Even a few of the 4-sector sites (3-sector splits) have band 12 on all 4 sectors.

    It's been known when they expansion coverage they did one sector to roll out out faster

    I think he means that on a sector, there is only a single band 12 antenna, vs Verizon which will have 3 or 4, for a total of 9-12 on the rack.

    Right, I got you. In the case of adding band 12, only one panel is necessary if b12 that is all they were adding (assuming the site was fully modernized to begin with). Rural cases are a bit different, but that's a conversation for another thread.

    This may be true some places but I've seen many two and three sector band-12 sites.

    To be short, T-Mobile's 600 MHz should have a much better range than 700 MHz. T-Mobile is currently limited on the power levels with B12, and I'm pretty sure this isn't the case with B71. With B12, I've only observed sites with 1 panel per sector. This is the typical set up in T-Mobile's Nokia and Ericsson markets. Overall, B71 should be better when it comes to range and building penetration compared to B12.
