LTE Cell Booster


Recommended Posts

Does anyone know if there are any Sprint LTE Boosters out yet. I found one by wilson but I have tried there boosters in the past which didnt work. When I asked Wilson about the problem they said there boosters are not guaranteed to work. Since then I have a Surecall 40db which has been a signifigant improvement.

With Sprint upgading alot of the towers out here I am keeping my eye out and was curious if anyone heard anything?

There are several designed to work with Verizon, T mobile, and AT&T lte. I've not seen any that work with sprint LTE service yet. The reviews on this one says it works with Sprint lte  but the specs say otherwise. Worth experimenting.

Wilson Sleek 4G claims to but I didn't get nearly as much of a signal boost from it for LTE (basically nothing) as I do for 3G (which it does very well).

Random thought....Wouldn't an existing booster in the 1900 Mhz spectrum work on LTE as well? Other carriers LTE are in different bands, but Sprint's (For now) is in the same band as PCS....So theroretically it should work with an existing 3G booster, because doesn't an amplifier just boost Signal not necessarily data. (G Block isn't that far off is it?)

No.  A booster is a transmitter, so it must receive FCC OET authorization -- just like the handset authorization that we often write about here at S4GRU.  If a booster is not tested and authorized for the PCS G block, then it will not work for Sprint's current LTE 5 MHz FDD carrier.  That the PCS G block is adjacent to the traditional PCS A-F blocks does not matter.

Thanks for the Clarification AJ....Was just a thought....Wasn't sure if it would work or not....

 

Thanks again!

And, correct me if I am wrong, all signal boosters, aka repeaters, are "active" devices, not "passive", in terms of wireless cellular payload. That is, the receiver and transmitter on each has to be aware of what type of signal it is, and what type of modulation technique is being used. It's not simply a chunk of spectrum where any enery above some threshold is Rx/Tx.

 

We just had our in-building rerpeater for Sprint replaced, as the old one (installed in 2007) stopped modulating the signals correctly (it was corrupting payloads). I overheard the tech from Ericsson who did the swap out talking about the active technology a bit.

The terms "booster" and "repeater," even "translator," may be used interchangeably, but there can be some differences among them.

 

In most cases, the set up is just a pair of separated antennas with an amp in between.  In that case, it is amplifying the raw RF -- the type of signal, modulation, FEC, etc., are immaterial.

 

But a far more expensive, sophisticated set up might demodulate and remodulate the signal, potentially even "translating" it to a different frequency.

Okay with lte active in some spots I decided to try my sure call dual band mobile amp CM2000-WL 40db. It seemed to improve the signal for 1st but made it slower on lte. Does anyone know why the difference?

 

If I understand you, you are asking why 1x was improved but not LTE?

 

According to the specs of your equipment, 1x (CDMA) is called out as a specifically supported technology, on a specifically supported frequency. LTE is not mentioned (because of the age of the equipment), Although whether that alone would be definitive in the case of a simple repeater I couldn't say. I can tell you however, that the actual frequencies used by the most widely deployed Sprint LTE (PCS G-Block), are not compatible to your equipment.

    • Excuse my rookie comments here, but after enabling *#73#, it seems that the rainbow sim V2? requires n70 (I turned it off along with n71 - was hoping to track n66) to be available else it switches to T-Mobile.  So this confirms my suspicion that you need to be close to a site to get on Dish.  Have no idea why they don't just use plmn. To test, I put it into a s21 ultra, rebooted twice, came up on T-Mobile (no n70 on s21).  Tried to manually register on 313340, but it did not connect (tried twice). I am on factory unlocked firmware but used a s22 hack to get *#73# working.  Tried what you were suggesting with a T-Mobile sim partially installed, but that was very unstable with Dish ( I think they had figured that one out).  [edit: and now I see Boost sent me a successful device swap notice which says I can now begin to use my new device.  Sigh.  Will try again later and wait for this message - too impatient.]
    • Hopefully this indicates T-Mobile hasn't completely abandoned mmwave and/or small cells? But then again this is the loop, so take that as you will. Hopefully now that most macro activity is done (besides rural colo/builds), they will start working on small cells.

    • In the conference call they had two question on additional spectrum. One was the 800 spectrum. They are not certain what will happen, thus have not really put it into their plans either way (sale or no sale). They do have a reserve level. Nationwide 800Mhz is seen as great for new technologies which I presume is IOT or 5g slices.  T-Mobile did not bite on use of their c-band or DOD.  mmWave rapidly approaching deadlines not mentioned at all. FWA brushes on this as it deals with underutilized spectrum on a sector by sector basis.  They are willing to take more money to allow FWA to be mobile (think RV or camping). Unsure if this represents a higher priority, for example, FWA Mobile in RVs in Walmart parking lots working where mobile phones need all the capacity. In terms of FWA capacity, their offload strategy is fiber through joint ventures where T-Mobile does the marketing, sales, and customer support while the fiber company does the network planning and installation.  50%-50% financial split not being consolidated into their books. I think discussion of other spectrum would have diluted the fiber joint venture discussion. They do have a fund which one use is to purchase new spectrum. Sale of the 800Mhz would go into this. It should be noted that they continue to buy 2.5Ghz spectrum from schools etc to replace leases. They will have a conference this fall  to update their overall strategies. Other notes from the call are 75% of the phones on the network are 5g. About 85% of their sites have n41, n25, and n71, 90% 5g.  93% of traffic is on midband.  SA is also adding to their performance advantage, which they figure is still ahead of other carriers by two years. It took two weeks to put the auction 108 spectrum to use at their existing sites. Mention was also made that their site spacing was designed for midrange thus no gaps in n41 coverage, while competitors was designed for lowband thus toggles back and forth for n77 also with its shorter range.  
    • The manual network selection sounds like it isn't always scanning NR, hence Dish not showing up. Your easiest way to force Dish is going to be forcing the phone into NR-only mode (*#*#4636#*#* menu?), since rainbow sims don't support SA on T-Mobile.
