Why do cell phones have such bad sound quality? I know immediately if someone calls me from a cell or mobile phone because there is such a high background noise of popping and crackling sound on the line. Is this normal?

Well, cell phones are essentially weak 2-way radios, and are subject to all the same sorts of interference and problems that other types of radios have. On top of those things, in order to get as many calls through as possible, voices are digitally compressed, and this introduces some distortion, and errors in the data can result in a lot of cutting out and crackling. So, yeah, in the real world it's pretty normal. The only way to improve that, really, is to add more ugly cell towers so that the distance the radio has to transmit is reduced.

Yes it's normal. And it varies, I use Net10 and find they do pretty well. Older analog cell phones sounded better, but with digital they can get more calls through on the same radio signals. So poor quality is here to stay. It may be worth trying different providers as they have different characteristics. Also different phones - I find Nokia sound relatively clear (sharp, hard and tinny - but clear) but Motorola (and other phones using Motorola chipsets) sound soft and fuzzy and are difficult to understand.

Some interference is completely normal. Two factors. First off, cell phones are wireless so you don't have complete control of the circuit and the radios are open to interference like any radio. Also, more and more of us use headsets when we talk on the phone, and these also can introduce background noise or additional interference when they are also wireless. If you often can't get a reliable signal in the areas you use your phone you might consider a different provider. The other thing to consider is the phones themselves. Some phones do better than others both in terms of receiving signal, and in reproducing voice. You might try different models of phones to see which get the best signal and which sound best to you. Note, SOME interference is normal. There can always be radio interference but when you have a good phone and a strong signal your calls should be mostly clear.

It will depend on cellphone models. Frequency reciever has different level, the higher the cost the better the quality. Try use VOIP Phones(http://www.ringcentral.com) for longdistance calls with no extra charges.
