Legacy towers vs Nv towers


Recommended Posts

Assuming only the 1900mhz band is active on both towers, would the nv have any better coverage than the legacy tower since the antennas are new?

 

Also if my dBm signal on 3g is -95 Rssi, would that be fairly quick on lte is converted to rssp?

With the new NV equipment, you should see a gain in signal strength, thanks to the RRUs being mounted directly behind the antennas. This reduces the signal loss that would occur when running coax down the tower to the base cabinet.

 

Hopefully someone else can weigh in on this, but -95 RSSI would likely be a relatively weak signal for LTE. It should work fine, but you probably won't see speeds higher than about 5Mbps downstream.

-95dBm RSSI is the maximum threshold for LTE. Depending on your LTE device, you either will have a weak LTE signal, a spotty LTE signal or none at all.

 

The gain expected from legacy to NV gear should be between 1dBm and 5dBm, roughly. However, some indoor coverage will be unaffected because of material types. Large metal roofs, CMU (cinder block), stucco with metal lath, adobe are brutal for RF propagation. Also some types of windows block RF, dual/triple pane windows with argon spacing, LO-E glass and LO-E² glass are especially limiting to RF.

My house is a hit or miss. I have -67dBm sometimes and then it jumps to -91dBm. My 3g speeds are 2.7mbps so I think lte will be fairly strong here. ;)

 

Thanks for the responses.

With that drastic of a difference, you are likely on different sites when you have the weaker/stronger signals. So, I would feel good about that. You should be in a good spot for LTE from the -67dBm site.

    • Definite usage quirks in hunting down these sites with a rainbow sim in a s24 ultra. Fell into a hole yesterday so sent off to T-Mobile purgatory. Try my various techniques. No Dish. Get within binocular range of former Sprint colocation and can see Dish equipment. Try to manually set network and everybody but no Dish is listed.  Airplane mode, restart, turn on and off sim, still no Dish. Pull upto 200ft from site straight on with antenna.  Still no Dish. Get to manual network hunting again on phone, power off phone for two minutes. Finally see Dish in manual network selection and choose it. Great signal as expected. I still think the 15 minute rule might work but lack patience. (With Sprint years ago, while roaming on AT&T, the phone would check for Sprint about every fifteen minutes. So at highway speed you could get to about the third Sprint site before roaming would end). Using both cellmapper and signalcheck.net maps to hunt down these sites. Cellmapper response is almost immediate these days (was taking weeks many months ago).  Their idea of where a site can be is often many miles apart. Of course not the same dataset. Also different ideas as how to label a site, but sector details can match with enough data (mimo makes this hard with its many sectors). Dish was using county spacing in a flat suburban area, but is now denser in a hilly richer suburban area.  Likely density of customers makes no difference as a poorer urban area with likely more Dish customers still has country spacing of sites.
    • Mike if you need more Dish data, I have been hunting down sites in western Columbus.  So far just n70 and n71 reporting although I CA all three.
    • Good catch! I meant 115932/119932. Edited my original post I've noticed the same thing lately and have just assumed that they're skipping it now because they're finally able to deploy mmWave small cells.
    • At some point over the weekend, T-Mobile bumped the Omaha metro from 100+40 to 100+90 of n41! That's a pretty large increase from what we had just a few weeks ago when we were sitting at 80+40Mhz. Out of curiosity, tested a site on my way to work and pulled 1.4Gpbs. That's the fastest I've ever gotten on T-Mobile! For those that know Omaha, this was on Dodge street in Midtown so not exactly a quiet area!
