T-Mobile vs Sprint Signal Strength Question

[Ascertion]

Hey, there is still more to come. I will have that for you in the morning. Now, back to David with weather...:PAJ

You gotta deliver.

 

P.S. ever since LTE came live, I've had better 3G reception, too. It's at -79dBm on EvDo and -85 or so on CDMA.

Also get anywhere from -88 to -100 LTE.

[wyatt:-)]

Just wondering....I recently got myself a Nexus 4 and started a prepaid plan on it. I notice that my T-Mobile device always has better than a -80dBm which is really good on HSDPA+. Meanwhile, Sprint (who is on the same tower, although Sprint is on the higher row) yields me around -85 to -90dBm which is weak for CDMA. The panels appear to be facing the same direction (sprint and T-Mobile). Why would T-Mobile be yielding a much stronger signal strength than Sprint at my home?

 

Not dissing Sprint, just curious. Is it because T-Mobile is 1700mhz and Sprint is 1900?

Same in my area, except Sprint is -80dBm and better, while T-Mobile is -110. Same tower.

What do I need to deliver?  I must have forgotten anything else that I had to say on the subject.

 

As for improvements in CDMA2000 signal reception, that was to be expected with the new antennas and RRUs.

So, all other factors equal -- frequency, power, modulation, coding -- could we agree that, say, an isolated ~8 kbps W-CDMA voice channel has a potential spreading gain advantage over an isolated ~8 kbps CDMA1X voice channel?

While that may be true, it's kind of irrelevant because don't most/all HSPA use a higher modulation?

Why would it be irrelevant?  W-CDMA is used for voice; HSPA is not.

Oh yea, guess I have LTE on the mind.

HSPA+ can use 64-QAM, but if I recall correctly, Rel 99 W-CDMA is limited to QPSK, just like CDMA1X.

This article agrees with you, so that's good enough for me.
