Towers.
Is there a way in which I can tell by just looking at a tower whether it's a GSM or CDMA tower? Are they are different from each other?
...
there isn't really a way to tell. from my experiences the cdma and old tdma towers are a but shorter in height. at least in my area.
...
Not really. Many/most towers are owned by tower management companies, not carriers. They may have every carrier in an area on a particular tower - CDMA, GSM, etc...
...
Anyone know how far towers reach? I understand GSM is different than CDMA. And it also has to do with terrain, weather, etc. But what is the distance they are suppose to reach based on perfect conditions? Please no one guess.

There is no correct answer to your question. Towers are tuned and directed based on need and capacity.
Just because you know where a tower is located has nothing to do with coverage in your area.
Towers can reach up to 15 miles in each direction in some cases but that is generally only in areas like rural highway coverage.

Thats right, although the average tower other then rural highway towers, are generally 3-5 miles, for GSM, not sure about CDMA.

CDMA is higher frequency, 1900 MHz, which means it doesn't travel as far. A tower has about a 2-3 mile range...line of sight. In the winter signals go a bit farther because there are no leaves on trees. Obviously wind, weather, etc. are going to have an effect on signal...also with the technology that CDMA is...if a tower starts getting swamped with connections...it will start to reduce it's effective range, to cut down on the number of people it is covering...but I have never had this cause a dropped call. In fact, I've only had one dropped call in over 2 years...
While the range for a Sprint or Verizon tower may be less...it is better for transmitting data, and having clearer calls. This is offset by constructing more towers...which Spr...

Nonsense. 1900 "PCS" can be used with any technology whether it's CDMA, TDMA (IS-136) or GSM.

Actually the 1900 MHz band does not travel farther, all things being equal. The 1900 MHz band is a higher frequency and therefore, all other things being equal, has a smaller effective range.
Think of it this way, what do you hear when the car drives by with the bomming system? Bass. Bass is the lower frequency and therefore can travel farther distances.

In your area CDMA may be on the 1900 MHz frequency but CDMA is not solely on 1900 MHz.
Want to make sure there is proper seperation on those terms.

i was always told 20-30 miles in rural areas of course for gsm. with an average of 5-15 miles urban depending on freq. and density.
cdma i was told 15-25 miles rural of course. with an avreage of the same 5-15 miles urban depending on freq. and density.
the other guys were all pretty close, actual usage range where talk is clear before clipping out or bars get low is 3-12 miles in urban dense areas.

For GSM it's supposed to be 35km.
