Signal Problems??

I just got my Evo yesterday and at work & at home I am having very fluctuating signal levels. Coming from AT&Ts network I had pretty much full signal at work & at home. Other users on the Sprint network in my office have full signal but the most I get is 2-3 bars.

I have turned off GPS,WiFi,4g and still very low signal. Even if I exit the building and stand clear of any buildings it will constantly change from 1-2 bars to full signal.

Is this something common on the EVO and I just shouldn't worry about it?? I don't know another EVO user to compare signal strength with in the Orlando area.
 
Firstly, you can't compare other carrier's signals to Sprint and get any useful information other than the fact that other carriers might have more coverage in that one spot.

I have had a Pre, Hero and now the Evo. The Evo seems to get as good or better reception than either of my previous phones. What does NOT get good reception for me is wifi and 4G. My friend's 4G data card will pull signals at my house and work, where my Evo will not even pick up a signal.

If you want to know what your true reception is, download Real Signal. It will tell you in dBm. The higher the number, the better... but this is tricky cause it's negative. So a -70 is better than a -100. For some reason they took the ability to see signal strength out of the Evo while all other Sprint phones I've had had it.

Compare actual dBm to other Sprint phones and see what you get. That will tell you the true reception.

Here is the deal, from the ATT side of things when I had them I had full signal in my condo, when I ported over to Sprint I was down to 1-2 bars. When I went outside pretty much full signal. What happens is the CDMA frequency can not penetrate brick, concrete etc as effcient as GSM/HSPA (in my case my condo complex is Brick). So what did I do? I could have survived fine with the signal I had, however I bought an AIRAVE and now I get 100% signal (granted its 1x) but with WIFI I am all set.

As soon as I am in my parking lot, full signal no issues what so ever. I am fortunate that my office has a Sprint repeater so no signal issues in the office.

Am I the only one that finds it a bit ridiculous that we need to set up what amounts to a small cell tower in our living rooms to get a signal indoors?

I've never had issues with signals indoors, even with Verizon which I believe is also CDMA. And it's not like I live out in the boonies. I'm in one of the biggest cities in the country right on top of a huge interstate. Signal should be superb.

it's $100 plus $5/mon. great option but too expensive.
i drop calls now in my house (it's brick).

Its not that "CDMA frequency" can not penetrate objects as well as "GSM/HSPA" as the carriers all have low/high bands from 800-900/1700-2100 (AT&T uses a "Wideband CDMA" variant), so much as its the higher frequency range signal, regardless of carrier/technology, that "may" have issue with penetration. However the closer one's respective distance to the carrier's tower/antenna the less of an issue it becomes...discounting any other interference.

That said, if it helps, you could try what I did with my Droid, to help with weak signal:

Sprint is typically 1900mhz, whereas AT&T's 3G is at 850mhz typically. 850 penetrates better than 1900mhz. Also, the tower may be much closer with AT&T. The difference, for me, is that with 1-2 bars on Sprint, I get perfect reception. With AT&T, even full bars would give me dropped calls/data. And both are CDMA, btw. 3G AT&T is Wideband CDMA. Even LTE/Wimax are similar; ODMA in stead of CDMA.
